If we take an action as something I voluntarily do, does it ever make sense to say that reason causes me to act? Reason can tell me that smoking is bad for my health, so if I quit was reason the cause of my quitting? Without a desire to quit it seems that all the reasons in the world won't cause me to do anything. So, it really is that simple? Reasons are never causes?
