Although omission is a most serious defect in
1
classification, two points have been overlooked in
[p. 13]
the foregoing:
2 for we usually consider not only
whether an action is morally right or morally wrong,
but also, when a choice of two morally right courses
is offered, which one is morally better; and likewise,
when a choice of two expedients is offered, which one
is more expedient. Thus the question which Panaetius thought threefold ought, we find, to be divided
into five parts. First, therefore, we must discuss the
moral—and that, under two sub-heads; secondly, in
the same manner, the expedient; and finally, the
cases where they must be weighed against each other.
