Why would anybody be intimidated by mere words? I mean, neither I nor any other athiest that I know ever threatens violence. We never threaten to fly planes into skyscrapers. We never threaten suicide bombs. We are very gentle people. All we do is use words to talk about things like the cosmos, the origin of the universe, evolution, the origin of life. What's there to be frightened of? It's just an opinion.

[Richard Leakey is] a robust hero of a man, who actually lives up to the cliché, “a big man in every sense of the word.” Like other big men he is loved by many, feared by some, and not over-preoccupied with the judgments of any.

Such is the breathtaking speciesism of our Christian-inspired attitudes, the abortion of a single human zygote can arouse more moral solicitude and righteous indignation than the vivasection of any number of intelligent adult chimpanzees! The only reason we can be comfortable with such a double standard is that the intermediates between humans and chimps are all dead.

Time and again, my sociobiological colleagues have upbraided me as a turncoat, because I will not agree with them that the ultimate criterion for the success of a meme must be its contribution to Darwinian "fitness". At bottom, they insist, a "good meme" spreads because brains are receptive to it, and the receptiveness of brains is ultimately shaped by (genetic) natural selection.

We have the power to defy the selfish genes of our birth and, if necessary, the selfish memes of our indoctrination. We can even discuss ways of deliberately cultivating and nurturing pure, disinterested altruism - something that has no place in nature, something that has never existed before in the whole history of the world. We are built as gene machines and cultured as meme machines, but we have the power to turn against our creators. We, alone on earth, can rebel against the tyranny of the selfish replicators.

Luke [the gospel writer] screws up his dating by tactlessly mentioning events that historians are capable of independently checking. There was indeed a census under Governor Quirinius - a local census, not one decreed by Caesar Augustus for the Empire as a whole - but it happened too late in 6 AD, long after Herod's death.

The human psyche has two great sicknesses: the urge to carry vendetta across generations, and the tendency to fasten group labels on people rather than see them as individuals.
