Full Idea
An appropriate action, say the stoics, is that which, when done, admits of a reasonable defence, such as what is consistent in life, and this extends also to plants and animals.
Gist of Idea
An appropriate action is one that can be defended, perhaps by its consistency.

A Reaction
I love [Zeno's] word 'appropriate' here, since that strikes me as greatly clarifying the Aristotelian doctrine of the mean. In fact I love the whole of this idea. Appropriate actions can be defended. Cf T.Scanlon. Consistency is a good defence.
