First you said "All human actions are swayed by instinct." So your saying that it is instinct for you to believe in evolution and for me to beleive in creation even though we come from the same ancesters as you would say? that instinct says to kill our brothers? What if your wrong about these instincts are really free will with hints from a devine creator?
Second you said Instinctual Desires. What do you mean by instinct? What about desires? you also mentioned morality whats your definition of those words? The way im reading your statement these instincts can have good and bad consequences. i mean look at moths for instance the same bright colors that bring them to a flower might also bring them to a candle flame burning them. instinct is non discriminatory where as we as humans can discern between flowers and fire right? when was the last time you burnt yourself because you thought the candle was a yellow rose? and these desires you talk about these yearnings could they be hints from a devine creator? could God be trying to say something? what if your wrong about these so called instintual desires?
You mentioned there was no right or wrong, that statement cant be true then can it? that statement could be right for me but wrong for you or the exact opposite. It could be indiffrent. was what hittler did wrong? executing jews for their faith. how about dr. jack kevorkian? helping people commit suicide? what of abortion? where do you stand on abortion?
Teaching a dog not to poop on the floor is merely cause and effect not development between right and wrong. a dog knows that there is a punishment after pooping on the floor so it learns and retains that piece of information. its instincts are to eat, recreate, and protect it self from harm, it the dog gets kicked when it pees on my shoes it might not do it after a few tries. i recently read about an expirement where a man turned on a light and put a bowl of dogfood on the porch and the dog would come eat. after awhile he didnt put the food out but turned on the light and instantly the dog began to salivate, is having a light turned on instinct? no its a training
