Different questions generate different forms of practical reasoning. A contextually unrestricted ‘What shall I do?’ is too open to focus reflection. More determinately, an agent may ask, ‘Shall I do X, or Y?’ To answer that, he may need to weigh things up—as fits the derivation of ‘deliberation’ fromlibra(Latin for ‘scales’). Ubiquitous and indispensable though this is, I mention it only to salute it in passing. Or he may ask how to achieve a proposed end: if his end is to (...) do X, he may ask ‘How shall I do X?’ Or he may ask how to apply a universal rule or particular maxim. Aristotle supplies examples inDe Motu Animalium(7.701a7 ff.), whose wording I freely adapt to my own purposes:A1 reasons to a necessary means to achieving an end:I will make a cloak.To make a cloak I must do A.So, I will do A.
