  What gives Reid's claim appeal is the fact that when we deliberate we think that what we are deliberating about is up to us, and for Reid, what is up to us is identical to what is in our power. However, it's not clear that we have to think of actions as being in our power in order to be motivated to deliberate; the thought that our actions are ‘up to us’, a thought which is undeniably involved in deliberation, might be understood in some way which does not presuppose power. For instance, in thinking that what we do is ‘up to us’, we might just be thinking that if we're sufficiently motivated to do it, we will. By way of example, note that it's generally true that people who deliberate before they act do things that are more in their interests than those who simply act impulsively, without deliberation. Hence, if you are motivated to avoid impulsive action, that motive might lead you to deliberate, and your deliberation might, in turn, lead you to do something better than you would have done had you not deliberated. It is not clear that a person who was motivated to deliberate for this reason would be presuming himself or herself to be endowed with power in Reid's sense. Such a person might think merely that deliberation will produce motives that happen to give rise, for reasons entirely out of the agent's control, to better actions. In short, if we think of deliberation as motivated action, and if we can imagine a person being motivated to engage in it even in the absence of the belief that he or she is endowed with power, then Reid is wrong.
