you could go further. Most of people's behaviors don't seem to be acts of volition, and certainly people's feelings aren't. You don't have the energy (in an engineering sense) for that to be true. We're on autopilot. You can train it, and override it, in most circumstances. But (sorry, I'm indulging in pop psych which I've been known to ridicule in others) a lot of the credit people give themselves for thinking through their actions is misplaced, and is nothing more than an attempt to feel in control of themselves.
We're all really good at after-the-fact rationalization when trying to explain our own actions. I've seen convincing arguments that the speed at which your brain reaches decisions is incompatible with the time it takes to apply rational processes - your body has fired off a reaction or feeling already and your brain checks it slightly later against a more thoughtful analysis, hoping you haven't already done something stupid!
Getting pretty OT, sorry.
