Here’s a great video. It’s not short (31 mins) but its well worth watching right through – or downloading and watching later. Even watching several times, the speaker is so eloquent and precise with his language. In it Scott Clifton gives a thorough critique of the Christian apologetics understanding of morality. He also gives a good outline of secular morality – a rational, objectively-based morality.

Clifton stresses morality is important because it determines how we behave and how we interact with others. In the video he sets out to answer four questions:
-What do we specifically mean by words like “right,” “wrong,” “moral,” “immoral,” etc.?
-Why are our definitions useful and applicable, and why do they represent how the vast majority of people see these words, whether they realise it or not?
-How can we objectively determine what is “right” and what is “wrong” without appealing to personal taste or subjective opinion?
-Why ought we to do right and not do wrong?
He answers the first question by defining “right” by that which promotes the health, happiness and well-being of humans, or minimises unnecessary human pain or suffering. And “wrong” of course is the converse.
