We seem to do little more than lurch between wanting and not wanting. Thus, the question naturally arises: Is there more to life than this? Might it … - Sam Harris

Given the right experimental manipulations, people can be led to believe that they consciously intended an action when they neither chose it nor had control over their movements.

The temptation to start each day with several glazed donuts and to end it with an extramarital affair might be difficult for some people to resist, for reasons that are easily understood in evolutionary terms, but there are surely better ways to maximize one’s long-term well-being.

You need an argument, and the nature of any argument is that its validity doesn't depend on who you are. [...] When talking about violence, again, the facts are whatever they are – how many people got shot, how many died, what was the color of their skin, who shot them, what was the color of their skin. Getting a handle on these facts does not require one to say, 'As a black man, I know x, y, and z .' The color of your skin simply isn't relevant information.

When talking about the data – that is, what is happening throughout a whole society – your life experience isn't relevant information. And the fact that you think it might be is a problem. [...] Now this isn't to say that a person's life experience is never relevant to a conversation [...] it can be used to establish certain kinds of facts. I mean, if someone says to you, 'Catholics don't believe in hell', it's perfectly valid to resort, 'Actually my mom is a Catholic, and she believes in hell'. Of course there's a larger question of what the Catholic doctrine actually is – but if a person is making a statement about a certain group of people and you are a member of the group, you might very well be in a position to falsify his claim on the basis of your experience.

But a person's identity and life experience often aren't relevant when talking about facts. And they're usually invoked in ways that are clearly fallacious.
