Philosophy is a bitter medicine with many fearsome side effects, but if you are able to stomach it, it can cure your soul of the many ills and infirmities of ignorance. Given the choice, most men prefer not to take it, and many of those who do soon find that they cannot carry on with it. In the end, they choose what is more pleasant over what is more wholesome, and prefer the society of those who encourage them in their follies to that of those who admonish and improve them. You, on the other hand, appear to be minded otherwise, for when a young man set for himself the highest standards of education and conduct, he naturally shuns the company of mindless nobodies and boldly seeks out that of the singular men who are prepared to teach him and challenge him and exhort him to virtue. In time, by his strivings, he will come to realize that it is from the hardest toil and noblest deeds that the purest and most persisting pleasures are to be had, and, taking pity on other men, and thinking also of the gods, he will do everything in his power to share this precious secret.
