in finding a teacher of those who are wholly ignorant. And this is true of virtue or of anything else; if a man is better able than we are to promote virtue ever so little, we must be content with the result. A teacher of this sort I believe myself to be, and above all other men to have the knowledge which makes a man noble and good; and I give my pupils their money's-worth, and even more, as they themselves confess. And therefore I have introduced the following mode of payment:--When a man has been my pupil, if he likes he pays my price, but there is no compulsion; and if he does not like, he has only to go into a temple and take an oath of the value of the instructions, and he pays no more than he declares to be their value. Such is my Apologue, Socrates, and such is the argument by which I endeavour to show that virtue may be taught, and that this is the opinion of the Athenians. And I have also attempted to show that you are not to wonder at good fathers having bad sons, or at good sons having bad fathers, of which the sons of Polycleitus afford an example, who are the companions of our friends here, Paralus and Xanthippus, but are nothing in comparison with their father; and this is true of the sons of many other artists. As yet I ought not to say the same of Paralus and Xanthippus themselves, for they are young and there is still hope of them. Protagoras ended, and in my ear 'So charming left his voice, that I the while Thought him still speaking; still stood fixed to hear (Borrowed by Milton, "Paradise Lost".).'
