METAPHYSICS AND EPISTEMOLOGY
Sec. The stand-point and
purpose of the philosopher define his task, but they
do not necessarily prearrange the division of it.
That the task is a complex one, embracing many subordinate
problems which must be treated seriatim, is
attested both by the breadth of its scope and the
variety of the interests from which it may be approached.
But this complexity is qualified by the peculiar importance
which here attaches to unity. That which lends
philosophical quality to any reflection is a steadfast
adherence to the ideals of inclusiveness and consistency.
Hence, though the philosopher must of necessity occupy
himself with subordinate problems, these cannot be
completely isolated from one another, and solved successively.
Perspective is his most indispensable requisite, and
he has solved no problem finally until he has provided
for the solution of all. His own peculiar conceptions
are those which order experience, and reconcile
such aspects of it as other interests have distinguished.
Hence the compatibility of any idea with all other
ideas is the prime test of its philosophical sufficiency.
On these grounds it may confidently be asserted that
the work of philosophy cannot be assigned by the piece
to different specialists, and then assembled.
There are no special philosophical problems which can
be finally solved upon their own merits. Indeed,
such problems could never even be named, for in their
discreteness they would cease to be philosophical.
The case of metaphysics and
epistemology affords an excellent illustration.
The former of these is commonly defined as the theory
of reality or of first principles, the latter as the
theory of knowledge. But the most distinctive
philosophical movement of the nineteenth century issues
from the idea that knowing and being are identical.
The prime reality is defined as a knowing mind, and
the terms of reality are interpreted as terms of a
cognitive process. Ideas and logical principles
constitute the world. It is evident that
in this Hegelian philosophy epistemology embraces metaphysics.
In defining the relations of knowledge to its object,
one has already defined one’s fundamental philosophical
conception, while logic, as the science of
the universal necessities of thought, will embrace
the first principles of reality. Now, were one
to divide and arrange the problems of philosophy upon
this basis, it is evident that one would not have
deduced the arrangement from the general problem of
philosophy, but from a single attempted solution of
that problem. It might serve as an exposition
of Hegel, but not as a general philosophical programme.
Another case in point is provided
by the present-day interest in what is called “pragmatism."
This doctrine is historically connected with Kant’s
principle of the “primacy of the practical reason,”
in which he maintained that the consciousness of duty
is a profounder though less scientific insight than
the knowledge of objects. The current doctrine
maintains that thought with its fruits is an expression
of interest, and that the will which evinces and realizes
such an interest is more original and significant
than that which the thinking defines. Such a
view attaches a peculiar importance to the springs
of conduct, and in its more systematic development
has regarded ethics as the true propaedeutic
and proof of philosophy. But to make ethics the
key-stone of the arch, is to define a special philosophical
system; for it is the very problem of philosophy to
dispose the parts of knowledge with a view to systematic
construction. The relation of the provinces of
metaphysics, epistemology, logic, and ethics cannot,
then, be defined without entering these provinces
and answering the questions proper to them.
Sec. Since the above terms
exist, however, there can be no doubt but that important
divisions within the general aim of philosophy have
actually been made. The inevitableness of it appears
in the variety of the sources from which that aim
may spring. The point of departure will always
determine the emphasis and the application which the
philosophy receives. If philosophy be needed
to supplement more special interests, it will receive
a particular character from whatever interest it so
supplements. He who approaches it from a definite
stand-point will find in it primarily an interpretation
of that stand-point.
Sec. There are two sources
of the philosophical aim, which are perennial in their
human significance. He, firstly, who begins with
the demands of life and its ideals, looks to philosophy
for a reconciliation of these with the orderly procedure
of nature. His philosophy will receive its form
from its illumination of life, and it will be an ethical
or religious philosophy. Spinoza, the great seventeenth-century
philosopher who justified mysticism after the manner
of mathematics, displays this temper in his
philosophy:
“After experience had taught
me that all the usual surroundings of social
life are vain and futile; seeing that none of
the objects of my fears contained in themselves anything
either good or bad, except in so far as the mind is
affected by them, I finally resolved to inquire
whether there might be some real good having
power to communicate itself, which would affect
the mind singly, to the exclusion of all else:
whether, in fact, there might be anything of which
the discovery and attainment would enable me
to enjoy continuous, supreme, and unending happiness."
In pursuance of this aim, though he
deals with the problem of being in the rigorous logical
fashion of his day, the final words of his great work
are, “Of Human Freedom”:
“Whereas the wise man, in so
far as he is regarded as such, is scarcely at
all disturbed in spirit, but, being conscious of himself,
and of God, and of things, by a certain eternal necessity,
never ceases to be, but always possesses true acquiescence
of his spirit. If the way which I have pointed
out as leading to this result seems exceedingly
hard, it may nevertheless be discovered.
Needs must it be hard, since it is so seldom
found. How would it be possible if salvation were
ready to our hand, and could without great labor
be found, that it should be by almost all men
neglected? But all things excellent are
as difficult as they are rare."
Sec. On the other hand,
one who looks to philosophy for the extension and
correction of scientific knowledge will be primarily
interested in the philosophical definition of ultimate
conceptions, and in the method wherewith such a definition
is obtained. Thus the philosophy of the scientist
will tend to be logical and metaphysical. Such
is the case with Descartes and Leibniz, who are nevertheless
intimately related to Spinoza in the historical development
of philosophy.
“Several years have now elapsed,”
says the former, “since I first became
aware that I had accepted, even from my youth, many
false opinions for true, and that consequently what
I afterward based on such principles was highly
doubtful; and from that time I was convinced
of the necessity of undertaking once in my life
to rid myself of all the opinions I had adopted,
and of commencing anew the work of building from the
foundation, if I desired to establish a firm and
abiding superstructure in the sciences."
Leibniz’s mind was more predominantly
logical even than Descartes’s. He sought
in philosophy a supreme intellectual synthesis, a science
of the universe.
“Although,” he says retrospectively,
“I am one of those who have worked much
at mathematics, I have none the less meditated
upon philosophy from my youth up; for it always seemed
to me that there was a possibility of establishing
something solid in philosophy by clear demonstrations.
. . . I perceived, after much meditation,
that it is impossible to find the principles
of a real unity in matter alone, or in that
which is only passive, since it is nothing but a collection
or aggregation of parts ad infinitum."
Sec. Though these types
are peculiarly representative, they are by no means
exhaustive. There are as many possibilities of
emphasis as there are incentives to philosophical
reflection. It is not possible to exhaust the
aspects of experience which may serve as bases from
which such thought may issue, and to which, after
its synthetic insight, it may return. But it
is evident that such divisions of philosophy represent
in their order, and in the sharpness with which they
are sundered, the intellectual autobiography of the
individual philosopher. There is but one method
by which that which is peculiar either to the individual,
or to the special position which he adopts, may be
eliminated. Though it is impossible to tabulate
the empty programme of philosophy, we may name certain
special problems that have appeared in its history.
Since this history comprehends the activities of many
individuals, a general validity attaches to it.
There has been, moreover, a certain periodicity in
the emergence of these problems, so that it may fairly
be claimed for them that they indicate inevitable
phases in the development of human reflection upon
experience. They represent a normal differentiation
of interest which the individual mind, in the course
of its own thinking, tends to follow. It is true
that it can never be said with assurance that any age
is utterly blind to any aspect of experience.
This is obviously the case with the practical and
theoretical interests which have just been distinguished.
There is no age that does not have some practical consciousness
of the world as a whole, nor any which does not seek
more or less earnestly to universalize its science.
But though it compel us to deal abstractly with historical
epochs, there is abundant compensation in the possibility
which this method affords of finding the divisions
of philosophy in the manifestation of the living philosophical
spirit.
Sec. To Thales, one of the
Seven Wise Men of Greece, is commonly awarded the
honor of being the founder of European philosophy.
If he deserve this distinction, it is on account of
the question which he raised, and not on account of
the answer which he gave to it. Aristotle informs
us that Thales held “water” to be “the
material cause of all things." This crude theory
is evidently due to an interest in the totality of
things, an interest which is therefore philosophical.
But the interest of this first philosopher has a more
definite character. It looks toward the definition
in terms of some single conception, of the constitution
of the world. As a child might conceivably think
the moon to be made of green cheese, so philosophy
in its childhood thinks here of all things as made
of water. Water was a well-known substance, possessing
well-known predicates. To define all nature in
terms of it, was to maintain that in spite of superficial
differences, all things have these predicates in common.
They are the predicates which qualify for reality,
and compose a community of nature from which all the
individual objects and events of nature arise.
The successors of Thales were evidently dissatisfied
with his fundamental conception, because of its lack
of generality. They seized upon vaguer substances
like air and fire, for the very definiteness of the
nature of water forbids the identification of other
substances with it. But what is so obviously
true of water is scarcely less true of air and fire;
and it appeared at length that only a substance possessing
the most general characters of body, such as shape,
size, and mobility, could be thought as truly primeval
and universal. In this wise a conception like
our modern physical conception of matter came at length
into vogue. Now the problem of which these were
all tentative solutions is, in general, the problem
of metaphysics; although this term belongs to
a later era, arising only from the accidental place
of the discussion of first principles after physics
in the system of Aristotle. The attempt to secure
a most fundamental conception which attaches some
definite meaning to the reality including and informing
every particular thing, is metaphysics.
Sec. It must not be supposed
that metaphysics is dogmatically committed to the
reduction of all reality to a unity of nature.
It is quite consistent with its purpose that the parts
of reality should be found to compose a group, or
an indefinite multitude of irreducibly different entities.
But it is clear that even such an account of things
deals with what is true of all reality, and even in
acknowledging the variety of its constituents, attributes
to them some kind of relationship. The degree
to which such a relationship is regarded as intimate
and essential, determines the degree to which any metaphysical
system is monistic, rather than pluralistic.
But the significance of this difference will be better
appreciated after a further differentiation of the
metaphysical problem has been noted.
Sec. It has already been
suggested that the test of Thales’s conception
lay in the possibility of deriving nature from it.
A world principle must be fruitful. Now an abstract
distinction has prevailed more or less persistently
in metaphysics, between the general definition
of being, called ontology, and the study
of the processes wherewith being is divided into things
and events. This latter study has to do primarily
with the details of experience enumerated and systematized
by the natural sciences. To reconcile these,
or the course of nature, with the fundamental definition
of being, is the problem of cosmology.
Cosmology is the construing of the prima facie
reality in terms of the essential reality. It
is the proof and the explanation of ontology.
Since the most familiar part of the prima facie
reality, the part almost exclusively noticed by the
naïve mind, is embraced within the field of the physical
sciences, the term cosmology has come more definitely
to signify the philosophy of nature. It
embraces such an examination of space, time, matter,
causality, etc., as seeks to answer the most general
questions about them, and provide for them in the
world thought of as most profoundly real. Such
a study receives its philosophical character from its
affiliation with ontology, as the latter would find
its application in cosmology.
Sec. But in addition to
the consideration of the various parts of nature,
cosmology has commonly dealt with a radical and far-reaching
alternative that appeared at the very dawn of metaphysics.
Differences may arise within a world constituted of
a single substance or a small group of ultimate substances,
by changes in the relative position and grouping of
the parts. Hence the virtue of the conception
of motion. The theory which explains all differences
by motions of the parts of a qualitatively simple
world, is called mechanism. Another source
of change familiar to naïve experience is will,
or the action of living creatures. According
to the mechanical theory, changes occur on account
of the natural motions of the parts of matter;
according to the latter or teleological conception,
changes are made by a formative agency directed
to some end. Among the early Greek philosophers,
Leucippus was an exponent of mechanism.
“He says that the worlds arise
when many bodies are collected together into
the mighty void from the surrounding space and rush
together. They come into collision, and those
which are of similar shape and like form become
entangled, and from their entanglement the heavenly
bodies arise."
Anaxagoras, on the other hand, was
famed for his doctrine of the Nous, or Intelligence,
to whose direction he attributed the whole process
of the world. The following is translated from
extant fragments of his book, “+peri physeo:s+”:
“And Nous had power over the
whole revolution, so that it began to revolve
in the beginning. And it began to revolve first
from a small beginning; but the revolution now extends
over a larger space, and will extend over a larger
still. And all the things that are mingled
together and separated off and distinguished
are all known by the Nous. And Nous set in order
all things that were to be and that were, and
all things that are not now and that are, and
this revolution in which now revolve the stars
and the sun and the moon, and the air and the
ether that are separated off."
Sec. It is clear, furthermore,
that the doctrine of Anaxagoras not only names a distinct
kind of cause, but also ascribes to it an independence
and intrinsic importance that do not belong to motion.
Whereas motion is a property of matter, intelligence
is an originative power working out purposes of its
own choosing. Hence we have here to do with a
new ontology. If we construe ultimate being in
terms of mind, we have a definite substitute for the
physical theories outlined above. Such a theory
is scarcely to be attributed to any Greek philosopher
of the early period; it belongs to a more sophisticated
stage in the development of thought, after the rise
of the problem of epistemology. But Anaxagoras’s
sharp distinction between the material of the world
on the one hand, and the author of its order and evolution
on the other, is in itself worthy of notice.
It contains the germ of a recurrent philosophical
dualism, which differs from pluralism in that
it finds two and only two fundamental divisions of
being, the physical, material, or potential on the
one hand, and the mental, formal, or ideal on the
other.
Sec. Finally, the alternative
possibilities which these cosmological considerations
introduce, bear directly upon the general question
of the interdependence of the parts of the world, a
question which has already appeared as pertinent in
ontology. Monism and pluralism now obtain a new
meaning. Where the world process is informed
with some singleness of plan, as teleology proposes,
the parts are reciprocally necessary, and inseparable
from the unity. Where, on the other hand, the
processes are random and reciprocally fortuitous, as
Leucippus proposes, the world as a whole is an aggregate
rather than a unity. In this way uniformity in
kind of being may prevail in a world the relations
of whose parts are due to chance, while diversity in
kind of being may prevail in a world knit together
by some thorough-going plan of organization.
Thus monism and pluralism are conceptions as proper
to cosmology as to ontology.
But enough has been said to demonstrate
the interdependence of ontology and cosmology, of
the theory of being and the theory of differentiation
and process. Such problems can be only abstractly
sundered, and the distinctive character of any metaphysical
system will usually consist in some theory determining
their relation. Philosophy returns to these metaphysical
problems with its thought enriched and its method
complicated, after becoming thoroughly alive to the
problems of epistemology, logic, and ethics.
Sec. Epistemology is the theory
of the possibility of knowledge, and issues from
criticism and scepticism. If we revert again to
the history of Greek philosophy, we find a first period
of enterprising speculation giving place to a second
period of hesitancy and doubt. This phase of
thought occurs simultaneously with the brilliantly
humanistic age of Pericles, and it is undoubtedly
true that energy is withdrawn from speculation largely
for the sake of expending it in the more lively and
engaging pursuits of politics and art. But there
are patent reasons within the sphere of philosophy
itself for entailment of activity and taking of stock.
For three centuries men have taken their philosophical
powers for granted, and used them without questioning
them. Repeated attacks upon the problem of reality
have resulted in no consensus of opinion, but only
in a disagreement among the wise men themselves.
A great variety of mere theories has been substituted
for the old unanimity of religious tradition and practical
life. It is natural under these circumstances
to infer that in philosophy man has overreached himself.
He would more profitably busy himself with affairs
that belong to his own sphere, and find a basis for
life in his immediate relations with his fellows.
The sophists, learned in tradition, and skilled in
disputation, but for the most part entirely lacking
in originality, are the new prophets. As teachers
of rhetoric and morals, they represent the practical
and secular spirit of their age; while in their avoidance
of speculation, and their critical justification of
that course, they express its sceptical philosophy.
Sec. In their self-justification
certain of the sophists attached themselves to a definite
doctrine maintained by those of their predecessors
and contemporaries who were atomists, or followers
of that same Leucippus whom we have quoted. This
doctrine was the result of an attempt to construe
perception in terms of the motion of atoms. Outer
objects were said to give off fine particles which,
through the mediation of the sense organs, impinged
upon the soul-atom. But it was evident even to
the early exponents of this theory that according to
such an account, each perceiver is relegated to a world
peculiar to his own stand-point. His perception
informs him concerning his own states as affected
by things, rather than concerning the things themselves.
Upon this ground the great sophist Protagoras is said
to have based his dictum: +Panto:n chre:mato:n
metron anthro:pos+, “Man is the
measure of all things.” This is the classic
statement of the doctrine of relativity. But
we have now entered into the province of epistemology,
and various alternatives confront us. Reduce thought
to perception, define perception as relative to each
individual, and you arrive at scepticism, or
the denial of the possibility of valid knowledge.
Plato expounds this consequence in the well-known discussion
of Protagoras that occurs in the “Theaetetus.”
“I am charmed with his doctrine,
that what appears is to each one, but I wonder
that he did not begin his book on Truth with a
declaration that a pig or a dog-faced baboon, or some
other yet stranger monster which has sensation,
is the measure of all things; then he might have
shown a magnificent contempt for our opinion
of him by informing us at the outset that while
we were reverencing him like a God for his wisdom,
he was no better than a tadpole, not to speak
of his fellow-men would not this have
produced an overpowering effect? For if
truth is only sensation, and no man can discern another’s
feelings better than he, or has any superior right
to determine whether his opinion is true or false,
but each, as we have several times repeated,
is to himself the sole judge, and everything
that he judges is true and right, why, my friend,
should Protagoras be preferred to the place of wisdom
and instruction, and deserve to be well paid, and we
poor ignoramuses have to go to him, if each one
is the measure of his own wisdom? . . .
The attempt to supervise or refute the notions
or opinions of others would be a tedious and enormous
piece of folly, if to each man his own are right; and
this must be the case if Protagoras’s Truth
is the real truth, and the philosopher is not
merely amusing himself by giving oracles out
of the shrine of his book."
This is the full swing of the pendulum
from dogmatism, or the uncritical conviction
of truth. A modified form of scepticism has been
developed in these later days under the influence of
natural science, and is called agnosticism
or positivism. It accepts the Protagorean
doctrine only in the sense of attributing to human
knowledge as a whole an incapacity for exceeding the
range of perception. Beyond this realm of natural
science, where theories can be sensibly verified, lies
the unknowable realm, more real, but forever inaccessible.
Sec. It is important to
note that both scepticism and agnosticism agree in
regarding perception as the essential factor in
knowledge. So far at any rate as our knowledge
is concerned, the certification of being consists
in perceivability. Knowledge is coextensive with
actual and possible human experience. This account
of the source and criterion of knowledge is called
empiricism, in distinction from the counter-theory
of rationalism.
The rationalistic motive was a quickening
influence in Greek philosophy long before it became
deliberate and conspicuous in Socrates and Plato.
Parmenides, founder of the Eleatic School, has left
behind him a poem divided into two parts: “The
Way of Truth” and “The Way of Opinion."
In the first of these he expounds his esoteric philosophy,
which is a definition of being established by dialectical
reasoning. He finds that being must be single,
eternal, and changeless, because otherwise it cannot
be thought and defined without contradiction.
The method which Parmenides here employs presupposes
that knowledge consists in understanding rather than
perception. Indeed, he regards the fact that
the world of the senses is manifold and mutable as
of little consequence to the wise man. The world
of sense is the province of vulgar opinion, while
that of reason is the absolute truth revealed only
to the philosopher. The truth has no concern with
appearance, but is answerable only to the test of rationality.
That world is real which one is able by thinking
to make intelligible. The world is what a world
must be in order to be possible at all, and the philosopher
can deduce it directly from the very conditions of
thought which it must satisfy. He who would know
reality may disregard what seems to be, provided he
can by reflective analysis discover certain general
necessities to which being must conform. This
is rationalism in its extreme form.
The rationalism of Socrates was more
moderate, as it was more fruitful than that of Parmenides.
As is well known, Socrates composed no philosophical
books, but sought to inculcate wisdom in his teaching
and conversation. His method of inculcating wisdom
was to evoke it in his interlocutor by making him
considerate of the meaning of his speech. Through
his own questions he sought to arouse the questioning
spirit, which should weigh the import of words, and
be satisfied with nothing short of a definite and
consistent judgment. In the Platonic dialogues
the Socratic method obtains a place in literature.
In the “Theaetetus,” which is, perhaps,
the greatest of all epistemological treatises, Socrates
is represented as likening his vocation to that of
the midwife.
“Well, my art of midwifery is
in most respects like theirs, but differs in
that I attend men, and not women, and I look after
their souls when they are in labor, and not after their
bodies: and the triumph of my art is in thoroughly
examining whether the thought which the mind
of the young man brings forth is a false idol
or a noble and true birth. And, like the midwives,
I am barren, and the reproach which is often made
against me, that I ask questions of others and
have not the wit to answer them myself, is very
just; the reason is that the god compels me to
be a midwife, but does not allow me to bring
forth. And therefore I am not myself at all wise,
nor have I anything to show which is the invention
or birth of my own soul, but those who converse
with me profit. . . . It is quite clear
that they never learned anything from me; the many
fine discoveries to which they cling are of their own
making."
The principle underlying this method
is the insistence that a proposition, to be true of
reality, must at least bespeak a mind that is true
to itself, internally luminous, and free from contradiction.
That which is to me nothing that I can express in
form that will convey precise meaning and bear analysis,
is so far nothing at all. Being is not, as the
empiricist would have it, ready at hand, ours for the
looking, but is the fruit of critical reflection.
Only reason, overcoming the relativity of perception,
and the chaos of popular opinion, can lay hold on
the universal truth.
A very interesting tendency to clothe
the articulations of thought with the immediacy of
perception is exhibited in mysticism, which
attributes the highest cognitive power to an experience
that transcends thought, an ineffable insight that
is the occasional reward of thought and virtuous living.
This theory would seem to owe its great vigor to the
fact that it promises to unite the universality of
the rational object with the vivid presence of the
empirical object, though it sacrifices the definite
content of both. The mystic, empiricist, and
rationalist are in these several ways led to revise
their metaphysics upon the basis of their epistemology,
or to define reality in terms dictated by the means
of knowing it.
Sec. But within the general
field of epistemology there has arisen another issue
of even greater significance in its bearing upon metaphysics.
The first issue, as we have seen, has reference to
the criterion of knowledge, to the possibility of
arriving at certainty about reality, and the choice
of means to that end. A second question arises,
concerning the relation between the knowledge and
its object or that which is known. This problem
does not at first appear as an epistemological difficulty,
but is due to the emphasis which the moral and religious
interests of men give to the conception of the self.
My knowing is a part of me, a function of that soul
whose welfare and eternal happiness I am seeking to
secure. Indeed, my knowing is, so the wise men
have always taught, the greatest of my prerogatives.
Wisdom appertains to the philosopher, as folly to
the fool. But though my knowledge be a part of
me, and in me, the same cannot, lightly at any rate,
be said of what I know. It would seem that I must
distinguish between the knowledge, which is my act
or state, an event in my life, and the known, which
is object, and belongs to the context of the outer
world. The object of knowledge would then be
quite independent of the circumstance that I know
it. This theory has acquired the name of
realism, and is evidently as close to
common sense as any epistemological doctrine can be
said to be. If the knowledge consists in some
sign or symbol which in my mind stands for the object,
but is quite other than the object, realism is given
the form known as the representative theory.
This theory is due to a radical distinction between
the inner world of consciousness and the outer world
of things, whereby in knowledge the outer object requires
a substitute that is qualified to belong to the inner
world. Where, on the other hand, no specific
and exclusive nature is attributed to the inner world,
realism may flourish without the representative theory.
In such a case the object would be regarded as itself
capable of entering into any number of individual
experiences or of remaining outside them all, and without
on either account forfeiting its identity. This
view was taken for granted by Plato, but is elaborately
defended in our own day. During the intervening
period epistemology has been largely occupied with
difficulties inherent in the representative theory,
and from that discussion there has emerged the theory
of idealism, the great rival theory
to that of realism.
Sec. The representative
theory contains at least one obvious difficulty.
If the thinker be confined to his ideas, and if the
reality be at the same time beyond these ideas, how
can he ever verify their report? Indeed, what
can it mean that an idea should be true of that which
belongs to a wholly different category? How under
such circumstances can that which is a part of the
idea be attributed with any certainty to the object?
Once grant that you know only your ideas, and the
object reduces to an unknown x, which you retain
to account for the outward pointing or reference of
the ideas, but which is not missed if neglected.
The obvious though radical theory of idealism is almost
inevitably the next step. Why assume that there
is any object other than the state of mind, since
all positive content belongs to that realm? The
eighteenth century English philosopher, Bishop Berkeley,
was accused by his contemporaries of wilful eccentricity,
and even madness, for his boldness in accepting this
argument and drawing this conclusion:
“The table I write on I say exists;
that is, I see and feel it: and if I were
out of my study I should say it existed; meaning
thereby that if I was in my study I might perceive
it, or that some other spirit actually does perceive
it. There was an odor that is,
it was smelt; there was a sound that is,
it was heard; a color or figure, and it was perceived
by sight or touch. This is all that I can
understand by these and the like expressions.
For as to what is said of the absolute existence
of unthinking things, without any relation to their
being perceived, that is to me perfectly unintelligible.
Their esse is percipi; nor is it
possible that they should have any existence
out of the minds or thinking thing which perceives
them."
Sec. In this paragraph Berkeley
maintains that it is essential to things, or at any
rate to their qualities, that they be perceived.
This principle when expressed as an epistemological
or metaphysical generalization, is called phenomenalism.
But in another phase of his thought Berkeley emphasizes
the perceiver, or spirit. The theory
which maintains that the only real substances are these
active selves, with their powers and their states,
has been called somewhat vaguely by the name of spiritualism.
Philosophically it shows a strong tendency to develop
into either panpsychism or transcendentalism.
The former is radically empirical. Its classic
representative is the German pessimist Schopenhauer,
who defined reality in terms of will because that
term signified to him most eloquently the directly
felt nature of the self. This immediate revelation
of the true inwardness of being serves as the key
to an “intuitive interpretation” of the
gradations of nature, and will finally awaken a sense
of the presence of the universal Will.
Sec. Transcendentalism,
or absolute idealism, on the other hand, emphasizes
the rational activity, rather than the bare
subjectivity, of the self. The term “transcendental”
has become associated with this type of idealism through
Kant, whose favorite form of argument, the “transcendental
deduction,” was an analysis of experience with
a view to discovering the categories, or formal principles
of thought, implied in its meaning. From the Kantian
method arose the conception of a standard or absolute
mind for the standard experience. This mind
is transcendental not in the sense of being alien,
but in the sense of exceeding the human mind in the
direction of what this means and strives to be.
It is the ideal or normal mind, in which the true
reality is contained, with all the chaos of finite
experience compounded and redeemed. There is
no being but the absolute, the one all-inclusive spiritual
life, in whom all things are inherent, and whose perfection
is the virtual implication of all purposive activities.
“God’s life . . . sees
the one plan fulfilled through all the manifold
lives, the single consciousness winning its purpose
by virtue of all the ideas, of all the individual
selves, and of all the lives. No finite
view is wholly illusory. Every finite intent
taken precisely in its wholeness is fulfilled in the
Absolute. The least life is not neglected, the
most fleeting act is a recognized part of the
world’s meaning. You are for the divine
view all that you know yourself at this instant
to be. But you are also infinitely more.
The preciousness of your present purposes to
yourself is only a hint of that preciousness
which in the end links their meaning to the entire
realm of Being."
The fruitfulness of the philosopher’s
reflective doubt concerning his own powers is now
evident. Problems are raised which are not merely
urgent in themselves, but which present wholly new
alternatives to the metaphysician. Rationalism
and empiricism, realism and idealism, are doctrines
which, though springing from the epistemological query
concerning the possibility of knowledge, may determine
an entire philosophical system. They bear upon
every question of metaphysics, whether the fundamental
conception of being, or the problems of the world’s
unity, origin, and significance for human life.
The term idealism is sometimes
applied to Plato on account of his designation of
ideas as the ultimate realities. This would be
a natural use of the term, but in our own day it has
become inseparably associated with the doctrine which
attributes to being a dependence upon the activity
of mind. It is of the utmost importance to keep
these two meanings clear. In the preferred sense
Plato is a realist, and so opposed to idealism.
The term idealism is further
confused on account of its employment in literature
and common speech to denote the control of ideals.
Although this is a kindred meaning, the student of
philosophy will gain little or no help from it, and
will avoid confusion if he distinguishes the term
in its technical use and permits it in that capacity
to acquire an independent meaning.
