"Faith is a vice pretending to be a virtue, its lies and errors and frothy nonsense deluding us and distracting us from action. There's no salvation in wishful thinking, only inertia. Faith is the enemy of reason. The one thing every single one of us here must be united in despising is faith. It's the barren refuge of the vacuous, the fearful, the frauds, and the obstacles to accomplishment."

“Look at the bible as a pastiche, a collection of mutually and often internally inconsistent fragments slapped together for crude reasons of politics and art and priestly self-promotion and sometimes beauty and a lot of chest-thumping tribalism, and through that lens, it makes a lot of sense. It does tell us something important…about us, not some fantastic mythological being. It tells us that we are fractious, arrogant, scrappy people who sometimes accomplish great things and more often cause grief and pain to one another. We want to be special in a universe that is uncaring and cold, and in which the nature of our existence is a transient flicker, so we invent these strange stories of grand beginnings, like every orphan dreaming that they are the children of kings who will one day ride up on a white horse and take them away to a beautiful palace and a rich and healthy family that will love them forever. We are not princes of the earth, we are the descendants of worms, and any nobility must be earned.”

“If you've got a religious belief that withers in the face of observations of the natural world, you ought to rethink your beliefs — rethinking the world isn't an option.”

“I have been told that my position won't win the creationist court cases. Do you think I care? I didn't become a scientist because I want to impress lawyers. The word for people who are neutral about truth is "liars.”

“People who say this cracker is literally and physically the body of their god and that I'm doing this great act of heresy and sacrilege and horror -- even though I didn't actually do anything to it -- is disturbing. It's like discovering there are witch doctors lurking in your community and they've been doing weird practices.”

“We're confronted all the time with evolving viruses and bacteria. The Red Queen really rules the biological world, and we have to keep running just to keep up pace with the changing microorganisms. Yet policymakers and the public deny vaccination, and evolution itself, and question the value of biomedical research. Maybe they don't believe in evolution, but the microorganisms trying to kill us are taking full advantage of it.”

“Nothing must be held sacred. Question everything. God is not great, Jesus is not your lord, you are not disciples of any charismatic prophet. You are all human beings who must make your way through your life by thinking and learning, and you have the job of advancing humanity's knowledge by winnowing out the errors of past generations and finding deeper understanding of reality. You will not find wisdom in rituals and sacraments and dogma, which build only self-satisfied ignorance, but you can find truth by looking at your world with fresh eyes and a questioning mind.”
