(ii.) The other point, though less important in itself, is even more important as indicating the strength of the Greek educational system. It is that we retain still its technical terms and many of its scholastic usages, either in their original Greek form or as translated into Latin and modified by Latin habits, in the schools of the West. The designation “professor” comes to us from the Greek sophists, who drew their pupils by promises: to “profess” was to “promise,” and to promise was the characteristic of the class of teachers with whom in the fourth century B.C. Greek education began. The title lost its original force, and became the general designation of a public teacher, superseding the special titles, “philosopher,” “sophist,” “rhetorician,” “grammarian,” and ending by being the synonym of “doctor.”[47] The practice of lecturing, that is of giving instruction by reading an ancient author, with longer or shorter comments upon his meaning, comes to us from the schools in which a passage of Homer or Plato or Chrysippus was read and explained. The “lecture” was probably in the first instance a student’s exercise: the function of the teacher was to make remarks or to give his judgment upon the explanation that was given: it was not so much _legere_ as _prælegere_, whence the existing title of “prælector.”[48] The use of the word “chair” to designate the teacher’s office, and of the word “faculty” to denote the branch of knowledge which he teaches, are similar survivals of Greek terms.[49] The use of academical designations as titles is also Greek: it was written upon a man’s tombstone that he was “philosopher” or “sophist,” “grammarian” or “rhetorician,” as in later times he would be designated M.A. or D.D.[50] The most interesting of these designations is that of “sophist.” The long academical history of the word only ceased at Oxford a few years ago, when the clauses relating to “sophistæ generales” were erased as obsolete from the statute-book.
