““Action is, by definition, always rational. One is unwarranted in calling goals of action irrational simply because they are not worth striving for from the point of view of one's own valuations. Such a mode of expressions leads to gross misunderstandings. Instead of saying that irrationality plays a role in action, one should accustom oneself to saying merely: There are people who aim at different ends from those that I aim at, and people who employ different means from those I would employ in their situation.””
