Most advocates of the nonphysical self have been happy enough with the immortality payoff not to obsess about the incoherence it carries with it. - Alexander Rosenberg

We have to acknowledge (to ourselves, at least) that many questions we want the "right" answers to just don't have any. These are the questions about the morality of stem-cell research or abortion or affirmative action or gay marriage or our obligations to future generations. Many enlightened people, including many scientists, think that reasonable people can eventually find the right answers to such questions. Alas, it will turn out that all anyone can really find are the answers that they like.

If you are going to be scientistic, you will have to be comfortable with a certain amount of nihilism.

Why is there anything at all? or as the question is famously put, Why is there something rather than nothing? Physics, especially quantum physics, shows that the correct answer to this question is: No reason, no reason at all.
