Such was the attitude of Socrates to the great teachers who since Thales downwards had preceded him in leading the intellectual advance of the most intellectual people of the ancient world. He stood forward as a teacher of moral science, as a preacher and philosophical missionary also; for in morals, the separation of theory from practice is an inconsistency of which only a feeble and imperfect nature is capable. Who, then, and of what quality, were his antagonists in the great regenerative work which he undertook? Not so much the physical philosophers, who might still pursue their researches or pamper their imaginations in their own speculative corners without disturbing the busy world, except in so far as they now and then might come into collision with theological orthodoxy, but the great untrained mass of the people themselves, and the pretentious array of a class of men who put themselves forward as their instructors,--the famous SOPHISTS. The word Sophists signifies professors of wisdom, in which sense Lucian calls our Saviour τὸν ἀνεσκολοπισμένον ἐκεῖνον σοφιστήν--_that crucified Sophist_--because He came forward as a public instructor professing to teach men wisdom. But as wisdom is a vague word (in fact σοφός in Greek signifies _clever_, and even {22} _cunning_ as often as _wise_), we must consult the circumstances of time and place to know what it exactly meant in any particular instance. The generation immediately preceding Socrates, when the Sophists first became prominent, was the era of the great Persian wars, and of the notable uprising of national spirit and of popular power which that memorable struggle called forth. How fiercely the strife between the old aristocratic and the new democratic element in Greek society had been raging in the immediately preceding epoch, the poems of Theognis may serve sufficiently to indicate; and now that by the battle of Salamis the political importance of the middle and sub-middle classes had been blazoned forth before universal Greece in glowing characters, the democracy in great commercial cities like Athens at once started into an attitude of hitherto unsuspected significance. New aspirations had been created, new pretensions were put forth, and new guides were required for a large class of people who felt themselves as it were suddenly shooting up from pupilage into majority. Now what guides had a people, circumstanced as the Athenians then, were, to look to for direction? The Church in those days--if we may call it a Church--was not a teaching body; its moral efficacy was exercised through sacred ceremonial and pious hymns; its intellectual agency was almost null. And though gymnastics and music, including a certain amount of the most popular literary culture, were common, there were no institutions like our Universities, for the severe and systematic discipline of the thinking faculties. A cry went up from the heart of the people for
