I often discuss a scientific approach to morality because I find this an interesting and developing field. However, morality is still sometimes linked in the public mind with religion, so it’s worth actually considering those religious arguments.
QualiaSoup is currently posting a useful YouTube video series on morality. I have posted No 2 below. It deals with the problems of religious morality, or the “divine command” concept of morality. It’s quite thorough.
There is at least one more video to come in this series.
No 1, Good without God, is below.
