That rule, moreover, shall be in perfect harmony with the Stoics'
system and doctrines. It is their teachings that
I am following in these books, and for this
reason: the older Academicians and your Peripatetics (who were once the same as the Academicians) give what is morally right the preference over
what seems expedient; and yet the discussion of
these problems, if conducted by those who consider
whatever is morally right also expedient and nothing
expedient that is not at the same time morally right,
will be more illuminating than if conducted by those
who think that something not expedient may be
morally right and that something not morally right
may be expedient. But our New Academy allows
us wide liberty, so that it is within my right to
defend any theory that presents itself to me as most
probable. But to return to my rule.
