Phizzy: "A lot of good, ethical and moral choices are made in Nature, by what some still like to think of as " lesser " species, co-operation and altruistic works are seen. If we have evolved the intelligence to work out what does the most good and the least harm, we should make those choices, not anything that comes short of that."
Agreed! But, we (humans) still don't know why other animals seem to demonstrate altruism or why they co-operate. For example, a recent YT video showed a lioness killing a ungulate and then apparently realising (?) it was pregnant and then attempting to revive (?) the fetus. Was the lioness's actions true mercy? Or, was it simply a response to a chemical messenger emitted by the killed beast.
It seems apparent that in spite of the biblical teaching at 2 Peter 2:12 (that governed western thought for centuries) that 'beasts' were 'destitute of reason' (hence the NWT's use of the word 'unreasoning'), animal behaviour can be interpreted as indicating some reasoning ability. So do animals 'think' about their conduct and actions?
And, if humans are animals (advanced or not) is intelligence the foundation of our actions, or is 'instinct' the starting point? Think about the English Protestant persecution of Catholics in Elizabethan times. Was it intelligent or merciful to burn people to death (mimicking the flames of hell)? We humans may think we are intelligent, but our behaviour is often stupid.
Which, of course, was the point of the author's remark at 2 Peter 2:12.(except his chosen illustration was false).
