“If there is a human moral to be drawn, it is that we must teach our children altruism, for we cannot expect it to be part of their biological nature.”

Indeed, organizing atheists has been compared to herding cats, because they tend to think independently and will not conform to authority.

The theory of evolution by cumulative natural selection is the only theory we know of that is in principle capable of explaining the existence of organized complexity.

We, alone on earth, can rebel against the tyranny of the selfish replicators.

Religion is regarded by the common people as true, by the wise as false, and by the rulers as useful.

We are going to die, and that makes us the lucky ones. Most people are never going to die because they are never going to be born.

Creationists eagerly seek a gap in present-day knowledge or understanding. If an apparent gap is found, it is assumed that God, by default, must fill it.

Religion is not the root of all evil, for no one thing is the root of all anything.

I don’t give a damn for anybody’s opinion, I only care about the facts. So I’m not an enthusiast for diversity of opinion where factual matters are concerned.

Any altruistic system is inherently unstable, because it is open to abuse by selfish individuals, ready to exploit it.

Faith is belief without evidence and reason; coincidentally that’s also the definition of delusion.

The meme for blind faith secures its own perpetuation by the simple unconscious expedient of discouraging rational inquiry.

Perhaps consciousness arises when the brain’s simulation of the world becomes so complex that it must include a model of itself.

The world and the universe is an extremely beautiful place, and the more we understand about it the more beautiful does it appear.

I suddenly realized that through no act of my own I had become biologically related to a new human being.

What’s been gratifying is to live long enough to see molecular biology and evolutionary biology growing toward each other and uniting in research efforts.

I just want everybody to know that I’m opposed to an unauthorized biography on anybody.

Man can be understood only by ascending from physics, chemistry, biology, and geology. In other words, he is first of all a cosmic problem.

We study biology, physics, movements of glaciers… Where are the classes on envy, feeling wronged, despair, bitterness.

Downloading a Tamagotchi egg onto my phone is possibly the loudest my biological clock has ever ticked.

We are living in times when technology, biology and chemistry have created the possibility of killing in large numbers.

After all, our families–our ancestors–are our identities. Biology is destiny.
