Oddly, since by now I've written quite a lot on early modern philosophers, I didn't care for the history of philosophy, which I thought dull and obscure, until I got a minor job writing articles for a children's encyclopedia in the history of science and began to make connections between science and philosophy.

Highly unequal societies are morally defective because they get to be that way through the exploitation by the clever and well-positioned ones of the vulnerabilities and weaknesses of others. The well-off then use their acquired political power to refuse to make sacrifices for others. This system brings us a wonderful range of products and experiences for consumers at the top of the privilege scale, but it also degrades and benumbs the workers at the lower end, as Adam Smith and Marx both said.

I had the idea that there were secret laws of the universe that could explain the baffling human reality around me, and that philosophers maybe had the key to them.

We have to gamble, and sometimes lose as George Ainslie argues; this keeps the appetite for life sharp.

Moral theory develops from the divine command theory of medieval Christian philosophy, mixed up with a bit of ancient pagan virtue theory, to the purely secular moral sentiment and interpersonal reaction theories of Smith and Hume, to Kant's attempt to restore command theory but with something supersensible in the individual rather than God as the source of authority.

In the academic setting, you take (typically) lonely, interesting middle-aged men and beautiful, intelligent young women, and everybody's motivations for display and conquest are engaged to the max. Sublimated, this can be a powerful force for the good - Plato had a lot to say about that - but acted upon it can bring evils without end.

Maybe we will get to this point and reach a decision one way or the other with 'Human cloning is acceptable,' but I doubt that it is ever going to happen for 'It is morally permissible to eat shrimp' or with the general formula 'Adultery is wrong,' whose intended extension is again very unclear.
