And when we look closely, we find a system of morals which any civilised person today should surely find poisonous. - Richard Dawkins

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.

Many of us shrink from judicial execution of even the most horrible human criminals, while we cheerfully countenance the shooting without trial of fairly mild animal pests. Indeed we kill members of other harmless species as a means of recreation and amusement. A human foetus, with no more human feeling than an amoeba, enjoys a reverence and legal protection far in excess of those granted to an adult chimpanzee. Yet the chimp feels and thinks and — according to recent experimental evidence — may even be capable of learning a form of human language.

[If] there is mercy in nature, it is accidental. Nature is neither kind nor cruel but indifferent.
