[reasons have a distinct causal role in actions]

22 ideas
Our reasoned acts are held to be voluntary and our own doing [Aristotle]
     Full Idea: It is our reasoned acts that are held to be in the fullest sense voluntary and our own doing.
     From: Aristotle (Nicomachean Ethics [c.334 BCE], 1169a01)
     A reaction: This seems to me crucial in morality. Morality concerns important decisions made by the core of a person. If we ask how 'core decisions' are known, their hallmark will be reasons, because reasons are the peak of human awareness.
We assign the cause of someone's walking when we say why they are doing it [Aristotle]
     Full Idea: Why is he going for a walk? We say 'to be healthy', and having said that we have assigned the cause.
     From: Aristotle (Physics [c.337 BCE], 194b33-5)
     A reaction: Stout gives this as the predecessor of Anscombe's account of intentions. The thought is that the explanation of the act is its purpose. Such teleology is more plausible than the Aristotelian teleology about non-human events.
Motivation is causality seen from within [Schopenhauer]
     Full Idea: Motivation is causality seen from within.
     From: Arthur Schopenhauer (Fourfold Root of Princ of Sufficient Reason [1813], p.214), quoted by Christopher Janaway - Schopenhauer 2 'Fourfold'
     A reaction: This is more illuminating about causation than about motivation, since we can be motivated without actually doing anything.
I want to suppress in myself the normal reasons people have for action [Cioran]
     Full Idea: I want to suppress in myself the reasons men invoke in order to exist, in order to act.
     From: E.M. Cioran (A Short History of Decay [1949], 1 'Gamut')
     A reaction: So much of our inner and moral life concerns not what we think or feel, but what we want to think or feel. The theory of action (if there can be such a thing) must account for these metareasons, which hover over us while we act.
It is an odd Humean view to think a reason to act must always involve caring [Foot]
     Full Idea: One would need a very special, very Humean, view about reasons for actions to think a man doesn't have a reason unless he cares.
     From: Philippa Foot (Interview with Philippa Foot [2003], p.34-5)
     A reaction: She says she used to believe this, but was wrong. It is hard to imagine acting for reasons if they don't care about anything at all (even that it's their job). But then people just do care about things.
The best explanation of reasons as purposes for actions is that they are causal [Davidson, by Smith,M]
     Full Idea: Davidson argues that the best interpretation of the teleological character of reason explanations is an intepretation in causal terms.
     From: report of Donald Davidson (Action, Reasons and Causes [1963]) by Michael Smith - The Moral Problem 4.4
     A reaction: That is, this is the explanation of someone doing something 'because' they have this reason (rather than happening to have a reason). Smith observes that other mental states (such as beliefs) may also have this causal power.
Reasons can give purposes to actions, without actually causing them [Smith,M on Davidson]
     Full Idea: Only the Humean theory is able to make sense of reason explanation as a species of teleological explanation, and one may accept that reason explanations are teleological without accepting that they are causal.
     From: comment on Donald Davidson (Action, Reasons and Causes [1963]) by Michael Smith - The Moral Problem 4.6
     A reaction: That is, reasons can give a purpose to an action, and thereby motivate it, without actually causing it. I agree with Smith. I certainly don't (usually, at least) experience reasons as directly producing my actions. Hume says desires are needed.
Early Davidson says intentional action is caused by reasons [Davidson, by Stout,R]
     Full Idea: In Davidson's earlier approach, intentional action requires causation by reasons.
     From: report of Donald Davidson (Action, Reasons and Causes [1963]) by Rowland Stout - Action 8 'Weakness'
     A reaction: A very Kantian idea, and one that seems to bestow causal powers on something which I take to be highly abstract. Thus Davidson was wrong (but in a nice way).
Reasons must be causes when agents act 'for' reasons [Davidson, by Lowe]
     Full Idea: It can be argued (by Davidson) that far from it being the case that reasons for and causes of action are quite distinct, reasons must be causes when agents act 'for' reasons.
     From: report of Donald Davidson (Action, Reasons and Causes [1963]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.9
     A reaction: Lowe argues against this view. The rival views to Davidson would be either that reasons are no more than desires-plus-beliefs in disguise, or that the will causes actions, and strong reasons carry a great weight with the will. I like the will.
Davidson claims that what causes an action is the reason for doing it [Davidson, by Kim]
     Full Idea: Davidson defends the simple thesis that the reason for which an action is done is the one that causes it, …which means that agency is possible only if mental causation is possible.
     From: report of Donald Davidson (Action, Reasons and Causes [1963]) by Jaegwon Kim - Philosophy of Mind p.127
Deviant causal chain: a reason causes an action, but isn't the reason for which it was performed [Davidson, by Neta]
     Full Idea: A 'deviant causal chain' is when an agent has a reason for performing an action, and for the reason to cause the performance, without that being the reason for which the agent performed it.
     From: report of Donald Davidson (Freedom to Act [1973]) by Ram Neta - The Basing Relation II
     A reaction: Davidson's thesis is that 'reasons are causes'. This was a problem he faced. I think this discussion is now obscured by the complex and multi-layered account of action which is emerging from neuroscience.
Reasons are 'internal' if they give a person a motive to act, but 'external' otherwise [Williams,B]
     Full Idea: Someone has 'internal reasons' to act when the person has some motive which will be served or furthered by the action; if this turns out not to be so, the reason is false. Reasons are 'external' when there is no such condition.
     From: Bernard Williams (Internal and External Reasons [1980], p.101)
     A reaction: [compressed] An external example given is a family tradition of joining the army, if the person doesn't want to. Williams says (p.111) external reason statements are actually false, and a misapplication of the concept of a 'reason to act'. See Idea 8815.
Explaining an action is showing that it is rational [Newton-Smith]
     Full Idea: To explain an action as an action is to show that it is rational.
     From: W.H. Newton-Smith (The Rationality of Science [1981], X.2)
Actions are not mere effects of reasons, but are under their control [Audi,R]
     Full Idea: An action for a reason is one that is, in a special way, under the control of reason. It is a response to, not a mere effect of, a reason.
     From: Robert Audi (Action, Intention and Reason [1992], p.177), quoted by Rowland Stout - Action 6 'Alien'
     A reaction: This modifies Davidson's 'reasons are causes'. Audi has a deviant causal chain which causes trouble for his idea, but Stout says he is right to focus on causal 'processes' (an Aristotelian idea) rather than causal 'chains'.
We feel belief and desire as reasons for choice, not causes of choice [Lowe]
     Full Idea: When we choose how to act in the light of our beliefs and desires, we do not feel our choices to be caused by them, but we conceive of them as giving us reasons to choose.
     From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 9)
     A reaction: I agree, though this 'feeling' could be a delusion, and we certainly don't need to start talking about a 'free' will. The best account of action seems to be that the will operates on the raw material of beliefs and desires. The will is our 'decision box'.
Rational decisions are either taken to be based on evidence, or to be explained causally [Conee/Feldman]
     Full Idea: In decision theory, there is a view according to which the rational basis for all decisions is evidential. This kind of decision theory is typically contrasted with causal decision theory.
     From: E Conee / R Feldman (Introduction to 'Evidentialism' [2004], p.3)
     A reaction: Your Kantian presumably likes rational reflection on evidence, and your modern reductive scientist prefers causality (which doesn't really sound very rational).
Beliefs, desires and intentions are not events, so can't figure in causal relations [Stout,R]
     Full Idea: Beliefs, desires and intentions are states of mind rather than events, but events are the only things that figure in causal relations.
     From: Rowland Stout (Action [2005], 5 'Do beliefs')
     A reaction: This is exactly why we have the concept of 'the will' - because it is a mental state to which we attribute active causal powers. We then have to explain how this 'will' is related to the other mental states (which presume motivate or drive it?).
A standard view says that the explanation of an action is showing its rational justification [Stout,R]
     Full Idea: The idea running through the work of Aristotle, Kant, Anscombe and Davidson is that explanation of action involves justifying that action or making it rationally intelligible.
     From: Rowland Stout (Action [2005], 5 'Psychological')
     A reaction: Stout goes on to say that instead you could give the 'rationalisation' of the action, which is psychological facts which explain the action, without justifying it. The earlier view may seem a little optimistic and intellectualist.
In order to be causal, an agent's reasons must be internalised as psychological states [Stout,R]
     Full Idea: It is widely accepted that to get involved in the causal process of acting an agent's reasons must be internalised as psychological states.
     From: Rowland Stout (Action [2005], 5 'Psychological')
     A reaction: This doesn't say whether the 'psychological states' have to be fully conscious. That seems unlikely, given the speed with which we perform some sequences of actions, such as when driving a car, or playing a musical instrument.
It is generally assumed that reason explanations are causal [Wilson/Schpall]
     Full Idea: The view that reason explanations are somehow causal explanations remains the dominant position.
     From: Wilson,G/Schpall,S (Action [2012], Intro)
     A reaction: I suspect that this is only because no philosopher has a better idea, and the whole issue is being slowly outflanked by psychology.
Causalists allow purposive explanations, but then reduce the purpose to the action's cause [Wilson/Schpall]
     Full Idea: Most causalists allow that reason explanations are teleological, but say that such purposive explanations are analysable causally, where the primary reasons for the act are the guiding causes of the act.
     From: Wilson,G/Schpall,S (Action [2012], 3)
     A reaction: The authors observe that it is hard to adjudicate on this matter, and that the concept of the 'cause' of an action is unclear.
Rather than requiring an action, a reason may 'entice' us, or be 'eligible', or 'justify' it [Orsi]
     Full Idea: Many have suggested alternative roles or sorts of reasons, which are not mandatory. Dancy says some reasons are 'enticing' rather than peremptory; Raz makes options 'eligible' rather than required; Gert says they justify rather than require action.
     From: Francesco Orsi (Value Theory [2015], 6.4)
     A reaction: The third option is immediately attractive - but then it would only justify the action because it was a good reason, which would need explaining. 'Enticing' captures the psychology in a nice vague way.
