Original post by viddy91.I see where you're coming from now, but what this essentially means is that life-forms display behaviour dedicated to achieveing their interests - in other words, they have instincts, or intuitions, that they should achieve their interests. These intuitions have been hardwired into life forms by natural selection. But, at the same time, caring for others is also an intuition displayed not only by humans, but by some nonhuman animals as well.
2.This is essentially the argument that I made earlier, but you then said "[f]ulfilling the interests of others is not rational". However, if a being has a desire to fulfill the interests or others due to his/her sense of right and wrong, then, by your argument and by the argument I presented a few posts ago, it is rational.
3.So, is it fair to say that we agree on this point? I agree with you on free will, incidentally.
4.I agree that morality is not objective, too. However, it seems we disagree on how subjective morality really is and, by extension, how similar people's ethical intuitions are, as well as how much they care. Point of interest, though, Peter Singer may have changed to some kind of objective utilitarian viewpoint now - see his new book, The Point of View of the Universe.
5. Firstly, in different cultures over the millennia, many have included some version of the Golden Rule in them, and many advocated helping the poor and the vulnerable. Like today, we see that these cultures didn't implement their ethics particularly well on a large scale, but, individually, the instinct to help others has been present, generally, in the human species, for a long time.
6. You claim that the fact that people don't always take actions in their life that are 'ethical' demonstrates that they don't care. On the contrary, humans are, generally, irrational creatures. We have cognitive biases, and these have been written about in detail by psychologists and behavioural economists. Pertinent to this discussion are biases to do with ethics: people, for instance, are more likely to help others when they're alone and they see someone struggling than when other people are around and they see someone struggling. Humans seem to like to share responsibility, but, thinking about these situations logically, there's no relevant difference - the goal, helping the struggling person, should still be met. There are a number of other cognitive errors holding people back from acting upon their ethical intuitions - it's not that they don't care; it's more that they're unaware that situation z is an ethical situation.
7.You point out that we live in an information-filled society in which people are bound to know that what they're doing is wrong. But, it's not that people consciously ignore this information, it's simply that they subconsciously put it to the back of their minds. And, often, humans will make rationalisations to justify their actions - in the case of eating nonhuman animals, which you mentioned, they'll make fallacious arguments, such as the appeal to nature ("it's only natural"), or the ad hominem attack ("vegans are sanctimonious"). So, they don't even think that they're doing something wrong in the first place.
