One imagines pleasure to be a good, another money; and yet the one may be called off from intemperance, the other from covetousness.

The other method and address, which, at the same time that it removes the false opinion, withdraws the disorder, has more subtlety in it; but it seldom succeeds, and is not applicable to vulgar minds, for there are some diseases which that medicine can by no means remove.

For, should any one be uneasy because he is without virtue, without courage, destitute of a sense of duty or honesty, his anxiety proceeds from a real evil; and yet we must apply another method of cure to him, and such a one as all the philosophers, however they may differ about other things, agree in.

For they must necessarily agree in this, that commotions of the mind in opposition to right reason are vicious; and that even admitting those things to be evils which occasion fear or grief, and those to be goods which provoke desire or joy, yet that very commotion itself is vicious; for we mean by the expressions magnanimous and brave, one who is resolute, sedate, grave, and superior to everything in this life; but one who either grieves, or fears, or covets, or is transported with passion, cannot come under that denomination; for these things are consistent only with those who look on the things of this world as things with which their minds are unequal to contend.
XXIX.

Wherefore, as I before said, the philosophers have all one method of cure, so that we need say nothing about what sort of thing that is which disturbs the mind, but we must speak only concerning the perturbation itself.
