“Human suffering has been caused because too many of us cannot grasp that words are only tools for our use.The mere presence in the dictionary of a word like 'living' does not mean it necessarily has to refer to something definite in the real world.”

“For more than three thousand million years, DNA has been the only replicator worth talking about in the world. But it does not necessarily hold these monopoly rights for all time. Whenever conditions arise in which a new kind of replicator can make copies of itself, the new replicators will tend to take over, and start a new kind of evolution of their own.”

“Let us try to teach generosity and altruism, because we are born selfish. Let us understand what our own selfish genes are up to, because we may then at least have the chance to upset their designs, something that no other species has ever aspired to do.”

“A consequentialist or utilitarian is likely to approach the abortion question in a very different way, by trying to weigh up suffering. Does the embryo suffer? (Presumably not if it is aborted before it has a nervous system; and even if it is old enough to have a nervous system it surely suffers less than, say, an adult cow in a slaughterhouse.) Does the pregnant woman, or her family, suffer if she does not have an abortion? Very possibly so; and, in any case, given that the embryo lacks a nervous system, shouldn't the mother's well-developed nervous system have the choice?”

“There is something infantile in the presumption that somebody else has a responsibility to give your life meaning and point… The truly adult view, by contrast, is that our life is as meaningful, as full and as wonderful as we choose to make it.”

“My objection to supernatural beliefs is precisely that they miserably fail to do justice to the sublime grandeur of the real world. They represent a narrowing-down from reality, an impoverishment of what the real world has to offer.”

“Let us remind ourselves of the terminology. A theist believes in a supernatural intelligence who, in addition to his main work of creating the universe in the first place, is still around to oversee and influence the subsequent fate of his initial creation. In many theistic belief systems, the deity is intimately involved in human affairs. He answers prayers; forgives or punishes sins; intervenes in the world by performing miracles; frets about good and bad deeds, and knows when we do them (or even think about doing them). A deist, too, believes in a supernatural intelligence, but one whose activities were confined to setting up the laws that govern the universe in the first place. The deist God never intervenes thereafter, and certainly has no specific interest in human affairs. Pantheists don't believe in a supernatural God at all, but use the word God as a non-supernatural synonym for Nature, or for the Universe, or for the lawfulness that governs its workings. Deists differ from theists in that their God does not answer prayers, is not interested in sins or confessions, does not read our thoughts and does not intervene with capricious miracles. Deists differ from pantheists in that the deist God is some kind of cosmic intelligence, rather than the pantheist's metaphoric or poetic synonym for the laws of the universe. Pantheism is sexed-up atheism. Deism is watered-down theism.”
