My thesis is that morality exists outside the human mind in the sense of being not just a trait of individual humans, but a human trait; that is, a human universal.

In science, if an idea is not falsifiable, it is not that it is wrong, it is that we cannot determine if it is wrong, and thus it is not even wrong.

Anecdotal thinking comes naturally; science requires training.

Science is not a thing. It's a verb. It's a way of thinking about things. It's a way of looking for natural explanations for all phenomena.

In principle, skeptics are neither closed-minded nor cynical. We are curious but cautious.

Accepting evolution does not force us to jettison our morals and ethics, and rejecting evolution does not ensure their constancy.

Through no divine design or cosmic plan, we have inherited the mantle of life's caretaker on the earth, the only home we have ever known.
