I don't believe, for instance, that evolutionary biology or any scientific endeavor has much to say about love. I'm sure a lot can be learned about the importance of hormones and their effects on our feelings. But do the bleak implications of evolution have any impact on the love I feel for my family? Do they make me more likely to break the law of flaunt society's expectations of me? No. I simply does not follow that human relationships are meaningless just because we live in a godless universe subject to the natural laws of biology.
