The noble soul occupies itself with wisdom and friendship.

Virtue consisteth of three parts,--temperance, fortitude, and justice.

I was not, I was, I am not, I care not. (Non fui, fui, non sum, non curo)

All other love is extinguished by self-love; beneficence, humanity, justice, philosophy, sink under it.

Luxurious food and drinks, in no way protect you from harm. Wealth beyond what is natural, is no more use than an overflowing container. Real value is not generated by theaters, and baths, perfumes or ointments, but by philosophy.

We must consider both the ultimate end and all clear sensory evidence, to which we refer our opinions; for otherwise everything will be full of uncertainty and confusion.

Moreover, the universe as a whole is infinite, for whatever is limited has an outermost edge to limit it, and such an edge is defined by something beyond. Since the universe has no edge, it has no limit; and since it lacks a limit, it is infinite and unbounded. Moreover, the universe is infinite both in the number of its atoms and in the extent of its void.
