The plural of anecdote is not data.

The initial animosity between divergent approaches can be overcome if we realize that each has something to offer that the other lacks. We may weave them together into a new whole that is stronger than the sum of its parts.

I am passionate about the truth. Passion is very different from fundamentalism.

[Some dogs] develop blood feuds with other dogs that are so serious that the only silver lining is a dog's inability to build nuclear weapons in the backyard. -- Patricia McConnell, A Tale of Two Species

[O]ur percept is an elaborate computer model in the brain, constructed on the basis of information coming from [the environment], but transformed in the head into a form in which that information can be used. Wavelength differences in the light out there become coded as 'colour' differences in the computer model in the head. Shape and other attributes are encoded in the same kind of way, encoded into a form that is convenient to handle. The sensation of seeing is, for us, very different from the sensation of hearing, but this cannot be directly due to the physical differences between light and sound. Both light and sound are, after all, translated by the respective sense organs into the same kind of nerve impulses. It is impossible to tell, from the physical attributes of a nerve impulse, whether it is conveying information about light, about sound or about smell. The reason the sensation of seeing is so different from the sensation of hearing and the sensation of smelling is that the brain finds it convenient to use different kinds of internal model of the visual world, the world of sound and the world of smell. It is because we internally use our visual information and our sound information in different ways and for different purposes that the sensations of seeing and hearing are so different. It is not directly because of the physical differences between light and sound.

I know that not all my readers like my digressions, but the research that has been done on Caenorhabditis elegans is such a ringing triumph of science that you aren't going to stop me.

Different sorts of survival machine appear very varied on the outside and in their internal organs. An octopus is nothing like a mouse, and both are quite different from an oak tree. Yet in their fundamental chemistry they are rather uniform, and, in particular, the replicators that they bear, the genes, are basically the same kind of molecule in all of us—from bacteria to elephants. We are all survival machines for the same kind of replicator—molecules called DNA— but there are many different ways of making a living in the world, and the replicators have built a vast range of machines to exploit them. A monkey is a machine that preserves genes up trees, a fish is a machine that preserves genes in the water; there is even a small worm that preserves genes in German beer mats. DNA works in mysterious ways.

Lacking a shared language, emotions are perhaps our most effective means of cross-species communication. We can share our emotions, we can understand the language of feelings, and that's why we form deep and enduring social bonds with many other beings. Emotions are the glue that binds.

Either blasphemy is a victimless crime or its victim is powerful enough to take care of himself without any help from you.

We are talking about a bet, remember, and Pascal wasn't claiming that his wager enjoyed anything but very long odds. Would you bet on God's valuing dishonestly faked belief (or even honest belief) over honest scepticism?

Even the staunchest atheist growing up in Western society cannot avoid having absorbed the basic tenets of Christian morality. Our societies are steeped in it: everything we have accomplished over the centuries, even science, developed either hand in hand with or in opposition to religion, but never separately. It is impossible to know what morality would look like without religion. It would require a visit to a human culture that is not now and never was religious. That such cultures do not exist should give us pause.

There was something built into the human brain by natural selection which was once useful, and which now manifests itself as religion.

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

The long-lived gene as an evolutionary unit is not any particular physical structure but the textual archival information that is copied on down the generations. [I]t is widely distributed in space among different individuals, and widely distributed in time over many generations. [A] successful gene will be one that does well in the environments provided by these other genes that it is likely to meet in lots of different bodies.

Make ethical choices in what we buy, do, and watch. In a consumer-driven society our individual choices, used collectively for the good of animals and nature, can change the world faster than laws.
