The true scientific understanding of the nature of existence is so utterly fascinating; how could you not want people to share it? Carl Sagan, I think, said 'when you're in love, you want to tell the world.' And who, on understanding a scientific view of reality, would not, as it were, fall in love and want to tell the world.
Richard DawkinsMost people understand that sexual lust has to do with propagating genes. Copulation in nature tends to lead to reproduction and so to more genetic copies. But in modern society, most copulations involve contraception, designed precisely to avoid reproduction. Altruism probably has origins like those of lust.
Richard DawkinsIt is all too easy to mistake passion that can change its mind for fundamentalism, which never will.
Richard DawkinsWhat you cannot have is a gene that sacrifices itself for the benefit of other genes. What you can have is a gene that makes organisms sacrifice themselves for other organisms under the influence of selfish genes.
