The traditional view of purpose says it comes from on high, from God, from the Creator. Darwin's idea of natural selection makes people uncomfortable because it reverses the direction of tradition. Whereas people used to think of meaning coming from on high and being ordained from the top down, now we have Darwin saying, "No, all of this design can happen, all of this purpose can emerge from the bottom up without any direction at all."
Daniel DennettI don't think there is any religious revival. I think what we are hearing, the furor, is merely the hysterical response of the churches the handwriting on the wall that they are seeing.
Daniel DennettYou don't get to advertise all the good that your religion does without first scrupulously subtracting all the harm it does and considering seriously the question of whether some other religion, or no religion at all, does better.
