[0:16] Speaker 1: History of Philosophy by William Turner, Chapter seventy four. Conclusion.
[0:23] Speaker 1: We have traced the origin and growth of philosophical opinions,
[0:27] Speaker 1: outlined the development of schools and systems of philosophy, and
[0:31] Speaker 1: indicated what seemed in each case to be an advance
[0:34] Speaker 1: in or a retrogression of philosophic thought. There remains the
[0:40] Speaker 1: task of inquiring into the general laws in obedience to
[0:43] Speaker 1: which philosophy took in the course of its development, the
[0:46] Speaker 1: particular direction which it has taken, that at one time
[0:51] Speaker 1: rather than at another, in one place rather than in another,
[0:55] Speaker 1: men should appear whose lives and thoughts had a decisive
[0:58] Speaker 1: influence on the course of the development of philosophy. That
[1:01] Speaker 1: countless factors, hereditary, temperamental, education, and so forth should result
[1:07] Speaker 1: in determining the philosophical career of such men. These are phenomena,
[1:12] Speaker 1: the origin of which lies beyond the scope of the
[1:14] Speaker 1: philosophy of history. They are data which must be considered
[1:19] Speaker 1: as given by experience, in much the same way as
[1:22] Speaker 1: that innate tendency to vary is taken as a datum
[1:25] Speaker 1: by the biologists, who restricts his investigation to answering the
[1:30] Speaker 1: question how is this tendency affected by environment? The task
[1:35] Speaker 1: of the philosophy of history is merely to inquire how
[1:38] Speaker 1: such data were influenced by social, political, religious, and other influences,
[1:44] Speaker 1: Starting therefore with the unexplained appearance of Plato, Aristotle, Saint Augustine,
[1:50] Speaker 1: Saint Thomas des Cart, Spinoza, how may we formulate the
[1:54] Speaker 1: laws to which these and other contributors to the development
[1:57] Speaker 1: of philosophic thought were influenced by the internal and external
[2:02] Speaker 1: conditions which, combined with the personal factor commonly called genius,
[2:08] Speaker 1: produce the changes and vicissitudes of the history of philosophy.
[2:13] Speaker 1: The laws of historical development are a posteriori laws. They
[2:18] Speaker 1: are not to be deduced from a priori principles, but
[2:21] Speaker 1: built up by a process of inductive reasoning from the
[2:24] Speaker 1: study of the facts of history. This does not mean
[2:27] Speaker 1: that history is the resultant of forces acting capriciously, but
[2:32] Speaker 1: that the forces which produce historical development being dependent on
[2:36] Speaker 1: physical conditions, mental temperament and the action and interaction of
[2:41] Speaker 1: social institutions, customs, and organizations are contingent, not necessarily causes.
[2:48] Speaker 1: That consequently, the philosophy of history is not a geometry
[2:52] Speaker 1: of the evolution and play of such forces, and that
[2:56] Speaker 1: the laws which it seeks to establish are not deductions
[2:59] Speaker 1: from definitions and axioms, but generalizations, similar to the post
[3:04] Speaker 1: facta generalizations of the statistician. Divine providence and human reason
[3:10] Speaker 1: are the two great factors which determine the course of history.
[3:14] Speaker 1: Sometimes these two work in unison. Sometimes they clash, and
[3:19] Speaker 1: the result is progress or deterioration. Wars, revolutions, conquests, educational reforms,
[3:26] Speaker 1: industrial reconstructions are all the work of man's mind, directed
[3:30] Speaker 1: but not quierced by divine providence. Now, divine providence works
[3:36] Speaker 1: through secondary causes and will, which is the motive power
[3:39] Speaker 1: of mind, though free, is not capricious, but follows certain
[3:44] Speaker 1: ascertainable laws in its efforts to advance to a higher
[3:47] Speaker 1: social state. The ground of historical development is therefore reason,
[3:52] Speaker 1: not pure reason deducing events as the logical mind deduces categories,
[3:58] Speaker 1: but reason rendered contingent by freedom and always subject to
[4:02] Speaker 1: the unreasoning opposition of passion and impulses. Consequently, the laws
[4:07] Speaker 1: of historical development are not a priori principles as they
[4:11] Speaker 1: should be if the ground of history were pure reason,
[4:15] Speaker 1: nor are they mere aggregations of facts, as they should
[4:18] Speaker 1: be if the ground of history were blind force. They
[4:22] Speaker 1: are a posteriori inductions based on observations, neither purely logical
[4:28] Speaker 1: nor biological, but psychological. The laws of historical development are
[4:34] Speaker 1: organic laws, that is to say, they deal with vital phenomena. Now,
[4:39] Speaker 1: organic laws differ from mechanical laws in this that, while
[4:42] Speaker 1: the latter may be expressed with quantitative accuracy, the former
[4:47] Speaker 1: can lay claim to qualitative definiteness merely. In physics, chemistry, astronomy,
[4:53] Speaker 1: and geology, the amount of force expend it can be
[4:56] Speaker 1: calculated and expressed in terms of some unit of measurement,
[5:00] Speaker 1: and the verification of the laws of these sciences includes
[5:03] Speaker 1: the establishment of a quantitative equivalence between the force expended
[5:08] Speaker 1: and the work accomplished. But when once we cross the
[5:11] Speaker 1: threshold of the biological sciences, we must be content with
[5:16] Speaker 1: the formulation of laws which are definite in every respect
[5:19] Speaker 1: save that of quantity. When therefore, the laws of historical
[5:23] Speaker 1: development formulate the relations between cause and effect. They do
[5:28] Speaker 1: not pretend to specify the definite amount of action and reaction.
[5:33] Speaker 1: Another peculiarity of the laws of historical development results from
[5:37] Speaker 1: what is commonly called the continuity of history. This is
[5:41] Speaker 1: based on a quality common to all manifestations of vital activity, namely,
[5:46] Speaker 1: the absolute indelibleness of an effect once produced on the
[5:50] Speaker 1: living organism. It is the peculiarity of living things rights Clifford,
[5:55] Speaker 1: not merely that they change under the influence of surrounding circumstances,
[6:00] Speaker 1: but that any change which takes place in them is
[6:03] Speaker 1: not lost, but retained, and as it were, built into
[6:07] Speaker 1: the organism to serve as the foundation for future actions.
[6:11] Speaker 1: You cause any distortion of the growth of a tree
[6:14] Speaker 1: and make it crooked. Whatever you may do afterwards to
[6:17] Speaker 1: make the tree straight, the mark of your distortion is there.
[6:21] Speaker 1: It is absolutely indelible. It has become part of the
[6:24] Speaker 1: tree's nature. No one can tell by examining the piece
[6:28] Speaker 1: of gold how often it has been melted and cooled
[6:31] Speaker 1: in geologic ages, by changes of the Earth's crust, or
[6:35] Speaker 1: even in the last year, by the hand of man.
[6:38] Speaker 1: Anyone who cuts down an oak can tell by the
[6:40] Speaker 1: rings in its trunk how many times winter has frozen
[6:43] Speaker 1: it into widowhood and summer has warmed it into life.
[6:47] Speaker 1: A living being must always contain within itself the history
[6:51] Speaker 1: not merely of its own existence, but of all its ancestors.
[6:55] Speaker 1: This peculiarity of living organisms, which may be likened to
[6:59] Speaker 1: the inertiae of physical force, appears an aggregate life as
[7:03] Speaker 1: the continuity of history and conditions. The development of philosophy
[7:07] Speaker 1: as well as that of every other vital product. The
[7:11] Speaker 1: philosophy of the history of philosophy is therefore the study
[7:15] Speaker 1: of the organic laws in obedience to which philosophy took
[7:18] Speaker 1: the particular course which it did take in its historical development.
[7:23] Speaker 1: Some of these laws we have already observed as occasion offered.
[7:27] Speaker 1: We have observed, for example, that a period of national
[7:30] Speaker 1: enthusiasm and national prosperity is usually one of great activity,
[7:35] Speaker 1: in a particular, of great constructive activity. In philosophy, we
[7:39] Speaker 1: have observed that the era of introspective philosophy corresponds with
[7:43] Speaker 1: the period of mental maturity of a nation. Similarly, laws
[7:48] Speaker 1: may be formulated expressive of the influence which climate, racial characteristics, literature, art, religion, etc.
[7:56] Speaker 1: Exercise on philosophy. Or again, laws may be formulated in
[8:00] Speaker 1: reference to conditions which are internal to philosophy itself, as
[8:04] Speaker 1: for example, that psychology is first dogmatic and afterwards critical,
[8:09] Speaker 1: or that a system of ethics is determined by the
[8:12] Speaker 1: psychology of the author or the school. We are, not, however,
[8:16] Speaker 1: concerned here with such particular laws, but rather with the
[8:20] Speaker 1: general formula under which all the particular laws, external and
[8:24] Speaker 1: internal of the history of philosophy may be subsumed. Such
[8:29] Speaker 1: a general formula is development. In the course of its history,
[8:33] Speaker 1: philosophy has passed from a relatively simple to a relatively
[8:37] Speaker 1: complex condition, from homogeneous to a heterogeneous state, from indeterminateness
[8:44] Speaker 1: to determinateness. But what are the characters of this development?
[8:49] Speaker 1: A glance of the secession of philosophical systems will convince
[8:53] Speaker 1: us that the evolution of philosophy has not followed in
[8:57] Speaker 1: increasing purpose. Philosophy is not always, in everywhere passed from
[9:01] Speaker 1: less to greater perfection. It has not gathered momentum as
[9:05] Speaker 1: it came down the ages. Truth has not come down
[9:08] Speaker 1: to us gaining power and volume in its course, like
[9:11] Speaker 1: the avalanche in its descent from the mountain tub If
[9:15] Speaker 1: philosophy were the gradual unfolding of an idea, if that
[9:18] Speaker 1: idea were the only reality, and if its evolution were
[9:22] Speaker 1: consequently monistic, the progress of philosophy should have been a
[9:26] Speaker 1: triumphal march from victory to victory, through province after province
[9:30] Speaker 1: of newly acquired truth, without a single reverse, without ever
[9:35] Speaker 1: retreating from territory once fairly won. Such we know has
[9:39] Speaker 1: not been the history of the philosophical sciences. The development
[9:43] Speaker 1: of philosophy has followed a more complicated course than that
[9:46] Speaker 1: of continued increase in perfection compit will be remembered distinguished
[9:51] Speaker 1: three stages in the development of human thought, namely the theological,
[9:56] Speaker 1: the metaphysical, and the positive or scientific. This generalization is
[10:02] Speaker 1: one sided. It judges all thought from the viewpoint of
[10:06] Speaker 1: positific prepossessions. Besides, it is inaccurate, for there have been
[10:11] Speaker 1: alternations of the metaphysical and the scientific periods in philosophy.
[10:16] Speaker 1: The age of Plato was metaphysical, that of Archimedes, Euclid
[10:20] Speaker 1: and Ptolemy was scientific. The thirteenth century returned to metaphysics,
[10:26] Speaker 1: the sixteenth was pre eminently a scientific century, while the
[10:30] Speaker 1: nineteenth went back to metaphysics in the form of transcendentalism,
[10:35] Speaker 1: still less accurate as cousins generalization according to which philosophy
[10:39] Speaker 1: has passed successively through the stages of sensism, idealism, skepticism, mysticism,
[10:47] Speaker 1: and eclecticism. According to Hegel, philosophy has, in the course
[10:52] Speaker 1: of its development, assumed different forms, each of which it
[10:55] Speaker 1: successively transcends, thus gaining a fuller, richer remark on crete content,
[11:01] Speaker 1: so that the progress of philosophy corresponds to the development
[11:05] Speaker 1: of logical categories being eleatics becoming heraclitis, individuality, atomness, etc.
[11:16] Speaker 1: No one will, however, maintain that Hegel's generalization meets with
[11:20] Speaker 1: more than an approximate verification from the study of the
[11:23] Speaker 1: facts of history. We shall be content here with describing
[11:28] Speaker 1: the development of philosophy in general terms as a process
[11:31] Speaker 1: of alternate progress in retrogression, a vast connected growth from
[11:36] Speaker 1: lower to higher with alternating periods of stagnation or degeneracy.
[11:41] Speaker 1: This alternation of progress in retrogression is a characteristic of
[11:45] Speaker 1: all development. Even in the evolutionary hypothesis, the survival of
[11:50] Speaker 1: the fittest does not necessarily mean the survival of the best. Indeed,
[11:55] Speaker 1: rhythm is equality of all motion whatsoever. In the physical
[11:59] Speaker 1: and zoological and the psychological, as well as in the
[12:03] Speaker 1: social order, progress is essentially conditioned by periosity. As in
[12:08] Speaker 1: the individual life, so in the aggregate life there is
[12:12] Speaker 1: a fluctuation of vitality, or rise and fall. The line
[12:16] Speaker 1: which represents human progress in industry, in art, in literature,
[12:20] Speaker 1: and in philosophy is not an ascending vertical nor a
[12:24] Speaker 1: straight line ascending obliquely from the horizontal, but an undulating curve,
[12:29] Speaker 1: like the record of the pulsation, now rising above the horizontal,
[12:33] Speaker 1: now falling below it, representing at different points the same
[12:37] Speaker 1: height of perfection or the same depth of degeneracy, but
[12:41] Speaker 1: never representing exactly the same condition of human progress. The
[12:46] Speaker 1: motion of the row boat floating with a tide, rising
[12:49] Speaker 1: and falling with each successive wave, yet constantly moving forward,
[12:54] Speaker 1: so that while it often rises to the same height,
[12:57] Speaker 1: it never rises twice to the same point of space
[13:01] Speaker 1: is an image of the progress of human thought, human customs,
[13:04] Speaker 1: and even human fashions, which are constantly changing and constantly
[13:09] Speaker 1: returning to previous conditions, without ever completing the circle of aggression.
[13:14] Speaker 1: The continuity of life demands at each successive moment in
[13:18] Speaker 1: life recapitulate the entire past iodym, said Elitter. If we
[13:23] Speaker 1: are to reduce to general terms the forces which combine
[13:26] Speaker 1: to cause this progress and retrogression of philosophic thought, we
[13:29] Speaker 1: shall find that on the side of progress are the
[13:32] Speaker 1: power of Him who wishes all men to come to
[13:35] Speaker 1: a knowledge of the truth, the attractiveness of truth itself,
[13:39] Speaker 1: the impetus given to philosophic speculation by a Plato and
[13:43] Speaker 1: Aristotle and Aquinas, and the enthusiasm of their followers. While
[13:48] Speaker 1: opposed to progress are the necessity of daily toil and
[13:52] Speaker 1: commercial spirit, greed, unworthy ambition, war, despotism, superstition, conservatism, fanaticism,
[14:02] Speaker 1: love of novelty, loyalty to tradition, and intellectual sloth. Through
[14:08] Speaker 1: these agencies does Divine Providence work out its designs by
[14:12] Speaker 1: these conditions, as human reason aided or hindered in its
[14:15] Speaker 1: efforts to arrive at a knowledge of the ultimate nature
[14:18] Speaker 1: of things. And by these factors are the rise and
[14:21] Speaker 1: fall of philosophy determined from Thales to Aristotle. There is
[14:27] Speaker 1: one great way of a progress, which, though ruffled by
[14:30] Speaker 1: petty wavelets of less successful movements, moves onward until contemporaneously,
[14:36] Speaker 1: with the downfall of Greece's political independence, it begins to
[14:40] Speaker 1: sync to the calm level of indifference to speculative effort.
[14:45] Speaker 1: The wave of progress next appears in the doctrines of
[14:47] Speaker 1: the Alexandrian school. It differs an aspect from the wave
[14:51] Speaker 1: which preceded it. It is less compact in form and
[14:55] Speaker 1: more easily broken. In the early centuries of the Christian era,
[14:59] Speaker 1: the the philosophical movement gathers strength once more and rises
[15:03] Speaker 1: to its greatest height in the thirteenth century, after which
[15:07] Speaker 1: conservatism indifference in sloth play the part of retrograding forces,
[15:12] Speaker 1: until with the opening of the modern era, another movement begins.
[15:17] Speaker 1: This movement has continued with alternating rise and fall until
[15:21] Speaker 1: our own day. It is risen at those points where
[15:24] Speaker 1: men like Descartes, Spinoza, Leibniz, Kant and Hegel have appeared.
[15:29] Speaker 1: It has fallen wherever adverse influences have predominated. But never
[15:34] Speaker 1: has it risen to the altitude attained by that wave
[15:37] Speaker 1: of human thought whose crest touched Heaven itself, when reason
[15:41] Speaker 1: and faith were united in one system of knowledge. Whither
[15:45] Speaker 1: will this movement bear us? Will carry us forward. We
[15:48] Speaker 1: cannot risk the progress of historical development, but will it
[15:52] Speaker 1: raise us to a height as great as that to
[15:54] Speaker 1: which the past attained? All will depend on the principles
[15:58] Speaker 1: on which philosophic speculates in the future will rest. It
[16:02] Speaker 1: has been well said that a cripple on the right
[16:04] Speaker 1: road will reach his destination sooner than the swiftest runner
[16:08] Speaker 1: who has started in the wrong direction. Philosophy today realizes
[16:12] Speaker 1: more than ever the importance of a right start and
[16:14] Speaker 1: a correct method. If therefore much of recent speculation has
[16:19] Speaker 1: made a wrong start, the sooner we return to the
[16:22] Speaker 1: principles of former and more successfully constructed systems, principles often
[16:27] Speaker 1: harshly expressed yet plainly pointing towards the truth. The sooner
[16:32] Speaker 1: will a genuine reform of philosophic method be possible. The
[16:36] Speaker 1: fullest appreciation of the past is compatible with the most
[16:39] Speaker 1: complete originality to modern philosophers. The challenge has err now
[16:44] Speaker 1: been addressed. Ye have removed our landmarks, give us others
[16:48] Speaker 1: that are better. Ye have taken away our foothold. What
[16:52] Speaker 1: have ye surer and safer in its place? The present
[16:56] Speaker 1: has much to learn from the past. If it is
[16:59] Speaker 1: vain to strive to seay stemmed the progress of the world.
[17:02] Speaker 1: It is equally vain to neglect the study of the past,
[17:05] Speaker 1: and to spend one's time in gloomily forecasting the future.
[17:09] Speaker 1: The principles which the past has bequeathed to us should
[17:12] Speaker 1: be adapted to the requirements of the future. And the
[17:15] Speaker 1: motto by which all enlightened advancement should be guided is
[17:19] Speaker 1: vetera novis ulgeri et perfiseri. End of Chapter seventy four,
