adhered closely to in my Tusculan Disputations. Therefore, as I have
acquainted you with the disputations of the three former days, this
book shall conclude the discussion of the fourth day. When we had come
down into the Academy, as we had done the former days, the business was
carried on thus:

_M._ Let any one say, who pleases, what he would wish to have
discussed.

_A._ I do not think a wise man can possibly be free from every
perturbation of mind.

_M._ He seemed by yesterday's discourse to be free from grief; unless
you agreed with us only to avoid taking up time.

_A._ Not at all on that account, for I was extremely satisfied with
your discourse.

_M._ You do not think, then, that a wise man is subject to grief?

_A._ No, by no means.

_M._ But if that cannot disorder the mind of a wise man, nothing else
can. For what--can such a man be disturbed by fear? Fear proceeds from
the same things when absent which occasion grief when present. Take
away grief, then, and you remove fear.

The two remaining perturbations are, a joy elate above measure, and
lust; and if a wise man is not subject to these, his mind will be
always at rest.
