THE PRE-SOCRATIC SCHOOLS.

"The first act in the drama of Grecian speculation was performed on the varied theatre of the Grecian colonies--Asiatic, insular, and Italian, verging at length (in Anaxagoras) towards Athens." During the progress of this drama two distinct schools of philosophy were developed, having distinct geographical provinces, one on the east, the other on the west, of the peninsula of Greece, and deriving their names from the localities in which they flourished. The earliest was the Ionian; the latter was the Italian school.

It would be extremely difficult, at this remote period, to estimate the influence which geographical conditions and ethnical relations exerted in determining the course of philosophic thought in these schools. Unquestionably those conditions contributed somewhat towards fixing their individuality. At the same time, it must be granted that the distinction in these two schools of philosophy is of a deeper character than can be represented or explained by geographical surroundings; it is a distinction reaching to the very foundation of their habits of thought. These schools represent two distinct aspects of philosophic thought, two distinct methods in which the human mind has essayed to solve the problem of the universe.

The ante-Socratic schools were chiefly occupied with the study of external nature. "Greek philosophy was, at its first appearance, a philosophy of nature." It was an effort of the reason to reach a "first principle" which should explain the universe. This early attempt was purely speculative. It sought to interpret all phenomena by hypotheses, that is, by suppositions, more or less plausible, suggested by physical analogies or by à priori rational conceptions.

Now there are two distinct aspects under which nature presents itself to the observant mind. The first and most obvious is the simple phenomena as perceived by the senses. The second is the relations of phenomena, cognized by the reason alone. Let phenomena, which are indeed the first objects of perception, continue to be the chief and almost exclusive object of thought, and philosophy is on the highway of pure physics. On the other hand, instead of stopping at phenomena, let their relations become the sole object of thought, and philosophy is now on the road of purely mathematical or metaphysical abstraction. Thus two schools of philosophy are developed, the one SENSATIONAL, the other IDEALIST. Now these, it will be found, are the leading and characteristic tendencies of the two grand divisions of the pre-Socratic schools; the Ionian is sensational, the Italian is idealist.

These two schools have again been the subject of a further subdivision based upon diverse habits of thought. The Ionian school sought to explain the universe by physical analogies. Of these there are two clear and obvious divisions--analogies suggested by living organisms, and analogies suggested by mechanical arrangements. One class of philosophers in the Ionian school laid hold on the first analogy. They regarded the world as a living being, spontaneously evolving itself--a vital organism whose successive developments and transformations constitute all visible phenomena. A second class laid hold on the analogy suggested by mechanical arrangements. For them the universe was a grand superstructure, built up from elemental particles, arranged and united by some ab-extra power or force, or else aggregated by some inherent mutual affinity. Thus we have two sects of the Ionian school; the first, Dynamical or vital; the second, Mechanical. [400]

The Italian school sought to explain the universe by rational conceptions and à priori ideas. Now to those who seek, by simple reflection, to investigate the relations of the external world this marked distinction will present itself: some are relations between sensible phenomena--relations of time, of place, of number, of proportion, and of harmony; others are relations of phenomena to essential being--relations of qualities to substance, of becoming to being, of the finite to the infinite. The former constituted the field of Pythagorean the latter of Eleatic contemplation. The Pythagoreans sought to explain the universe by numbers, forms, and harmonies; the Eleatics by the à priori ideas of unity, substance, Being in se, the Infinite. Thus were constituted a Mathematical and a Metaphysical sect in the Italian school. The pre-Socratic schools may, therefore, be tabulated in the following order:

I. IONIAN (Sensational), (1.) PHYSICAL {Dynamical or Vital.
{Mechanical.
II. Italian (Idealist), {(2.) MATHEMATICAL Pythagoreans.
{(3.) METAPHYSICAL Eleatics.

I. The Ionian or Physical School.--We have premised that the philosophers of this school attempted the explanation of the universe by physical analogies.
