“if you are willing to reflect on the courage and moderation of other people, you will find them strange...they all consider death a great evil...and the brave among them face death, when they do, for fear of greater evils...therefore, it is fear and terror that make all men brave, except for philosophers. yet it is illogical to be brave through fear and cowardice...what of the moderate among them? is their experience not similar?...they master certain pleasures because they are mastered by others...i fear this is not the right exchange to attain virtue, to exchange pleasures for pleasures, pains for pains, and fears for fears, the greater for the less like coins, but that they only valid currency for which all these things should be exchanged is wisdom.”
