Pascal's Wager and Piaget's Hierarchy of moral thinking As for question of humanity being an abstraction, I think it's irrelevant at this point because love of humanity doesn't commit the fallacy of composition and the word "humanity" doesn't dilute or ignore the fact that individuals who constitute it are our main concern. — TheMadFool
Thanks for the interesting and detailed reply, but at risk of being overly pedantic (which I guess is probably not such a problem on a philosophy forum !) I'd like to take issue with your assertion that the fact that humanity is an abstraction is irrelevant.
I do take your point that 'love of humanity' doesn't necessarily commit the fallacy of composition, but I think there is a deeper and more intractable problem with the abstract nature of the word 'humanity' - which is that I don't think it's a term that actually points to anything concrete or meaningful in the world, and instead serves as a kind of placeholder concept for people to displace emotions that would be socially unacceptable if acted out on real, existing human beings (emotions such as disgust, hatred, envy, despair, contempt etc). Hence the general tendency for people to talk about the state of humanity in such tragic terms as in your response above. My assertion is that while there are self-evidently negative aspects to real human nature, in reality the picture is nothing like as grim as it appears once we drop the philosopher's temptation to sit in judgement of real human beings, on the basis of an abstraction we've created ourselves, informed by the most lurid extremes of human behaviour.
