亚里士多德创立的新学科——逻辑学，使淹没在神话和寓言迷雾当中的古希腊思维慢慢清晰化。
Aristotle and Greek Science
II. The Work of Aristotle
It does not appear that Aristotle published in his life-time any technical writings except those on logic and rhetoric; and the present form of the logical treatises is due to later editing. In the case of the Metaphysics and the Politics the notes left by Aristotle seem to have been put together by his executors without revision or alteration. Even the unity of style which marks Aristotle's writings, and offers an argument to those who defend his direct authorship, may be, after all, merely a unity given them through common editing by the Peripatetic School. About this matter there rages a sort of Homeric question, of almost epic scope, into which the busy reader will not care to go, and on which a modest student will not undertake to judge. We may at all events be sure that Aristotle is the spiritual author of all these books that bear his name: that the hand may be in some cases another's hand, but that the head and the heart are his.
III. The Foundation of Logic
The first great distinction of Aristotle is that almost without predecessors, almost entirely by his own hard thinking, he created a new science—Logic. Renan speaks of "the ill training of every mind that has not, directly or indirectly, come under Greek discipline"; but in truth the Greek intellect itself was undisciplined and chaotic till the ruthless formulas of Aristotle provided a ready method for the test and correction of thought. Even Plato (if a lover may so far presume) was an unruly and irregular soul, caught up too frequently in a cloud of myth, and letting beauty too richly veil the face of truth. Aristotle himself, as we shall see, violated his own canons plentifully; but then he was the product of his past, and not of that future which his thought would build. The political and economic decay of Greece brought a weakening of the Hellenic mind and character after Aristotle; but when a new race, after a millennium of barbaric darkness, found again the leisure and ability for speculation, it was Aristotle's "Organon" of logic, translated by Boethius (470–525 A.D.), that became the very mould of medieval thought, the strict mother of that scholastic philosophy which, though rendered sterile by encircling dogmas, nevertheless trained the intellect of adolescent Europe to reasoning and subtlety, constructed the terminology of modern science, and laid the bases of that same maturity of mind which was to outgrow and overthrow the very system and methods which had given it birth and sustenance.

逻辑是一门科学，正确思维的程序可以像物理学和几何学一样简化成定律；逻辑也是一门艺术，钢琴家的手指在琴键上轻松自如地弹出优美的乐曲同样也需要逻辑的支持。

III. The Foundation of Logic
Logic means, simply, the art and method of correct thinking. It is the logy or method of every science, of every discipline and every art; and even music harbors it. It is a science because to a considerable extent the processes of correct thinking can be reduced to rules like physics and geometry, and taught to any normal mind; it is an art because by practice it gives to thought, at last, that unconscious and immediate accuracy which guides the fingers of the pianist over his instrument to effortless harmonies.
There was a hint of this new science in Socrates' maddening insistence on definitions, and in Plato's constant refining of every concept. Aristotle's little treatise on Definitions shows how his logic found nourishment at this source.
