 Because actions are produced by drives, you can only be fully active if you approve of your drives’ role; that in turn requires approving of the drives’ primary structural feature, namely, their ongoing production of challenging goals. It follows that whenever we do something, we have (or aspire to have, if we are less than fully active) a further aim (which, borrowing Nietzsche’s vocabulary, Katsafanas dubs ‘will to power’): that of selecting and structuring our activities so that they involve challenges we will exert ourselves in meeting.
