Central to this Stoic outlook is an understanding of what constitutes the good or most appropriate life for human beings. Whilst many thinkers might suppose health or wealth, the Stoics insist that the ultimate good must be good at all times. It is conceivable that wealth may be sometimes detrimental to me, and so too, even, health, if for example, my strength were put to ill-doing. Hence the Stoic conclusion that the only infallible good is virtue, which includes the usual list of Greco-Roman excellences: wisdom, justice, courage, and moderation.
