Featured Comment

The notion that humans are moral because morality is the result of natural selection acting on genes (e.g., the gene for oxytocin) is the naturalistic fallacy (defining good as some natural property).

If you can show that oxytocin promotes behaviors such as: trust, empathy, and cooperation, you still can ask the question: are trust, empathy, and cooperation good things or bad things?
