P. V. N. Myers, A General History for Colleges and High Schools…
“ This great philosopher believed that the proper study of mankind is man, his favorite maxim being "Know Thyself"; hence he is said to have brought philosophy from the heavens and introduced it to the homes of men. Socrates held the Sophists in aversion, and in opposition to their selfish expediency taught the purest system of morals that the world had yet known, and which has been surpassed only by the precepts of the Great Teacher. ”
