6 ideas
We avoid evil either through a natural aversion, or because we have acquired knowledge [Plato]
     Full Idea: Unless a man is born with a heaven-sent aversion to wrong-doing, or acquires the knowledge to refrain from it, he will never do right of his own free will.
     From: Plato (The Republic [c.374 BCE], 366c)
     A reaction: This is the territory explored so carefully by Aristotle (after he had read Republic!). It is hard to see what the knowledge could be, other than awareness of consequences.
Choice results when deliberation brings together an opinion with an inclination [Aristotle]
     Full Idea: Choice is neither simply wish nor opinion, but opinion together with inclination, whenever as a result of deliberation they are brought to a conclusion.
     From: Aristotle (Eudemian Ethics [c.333 BCE], 1227a04)
     A reaction: This seems to be the earliest appearance of the belief-plus-desire theory of action, which is often associated with Hume. A choice does not necessarily result from having the inclination and the appropriate opinion. Laziness!
Our motives don't explain our actions [Nietzsche]
     Full Idea: Human actions can in no way be explained by reference to human motives.
     From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 9[43])
     A reaction: He takes motives to come after the event. His view seems to be that our actions are deeply inexplicable. But if we explain why we performed some action, are we all and always lying? We give reasons, even if we don't know the source of the reasons.
Acting for a reason is a combination of a pro attitude, and a belief that the action is appropriate [Davidson]
     Full Idea: Whenever someone does something for a reason he can be characterised as (a) having some sort of pro attitude towards action of a certain kind, and (b) believing (or knowing, perceiving, noticing, remembering) that his action is of that kind.
     From: Donald Davidson (Action, Reasons and Causes [1963], p.3-4), quoted by Rowland Stout - Action 3 'The belief-'
     A reaction: This is the earlier Davidson roughly endorsing the traditional belief-desire account of action. He is giving a reductive account of reasons. Deciding reasons were not reducible may have led him to property dualism.
To control our actions better, make them result from our attitudes, not from circumstances [Kekes]
     Full Idea: We increase our control by making our actions more and more the effects of our attitudes, and less and less the effects of external forces acting on us independently of our attitudes.
     From: John Kekes (The Human Condition [2010], 02.4)
     A reaction: He says that the attitudes should be focused on our well-being. Attitudes may also, however, serve some exernal ideal, such as altruism or patriotism. He has built a case for 'control' being a much more important value than 'free will'.
Must all actions be caused in part by a desire, or can a belief on its own be sufficient? [Hursthouse]
     Full Idea: In contemporary philosophy of action, there is a fervid debate about whether any intentional action must be prompted in part by desire, or whether it is possible to be moved to action by a belief alone.
     From: Rosalind Hursthouse (On Virtue Ethics [1999], Intro)
     A reaction: I want a cool belief to be sufficient to produce an action, because it will permit at least a Kantian dimension to ethics, and make judgement central, and marginalise emotivism, which is the spawn of Satan.
