"[...W]e might try to understand exactly what loving your neighbor as yourself means. I have to love him as I love myself. Well, how exactly do I love myself?'
"Now that I come to think of it, I have not exactly got a feeling of fondness or affection for myself, and I do not even always enjoy my own society. So apparently 'Love your neighbor' does not mean 'feel fond of him' or 'find him attractive'. I ought to have seen that before, because, of course, you cannot feel fond of a person by trying. Do I think well of myself, think myself a nice chap? Well, I am afraid I sometimes do (and those are, no doubt, my worst moments) but that is not why I love myself. In fact it is the other way round: my self-love makes me think myself nice, but thinking myself nice is not why I love myself. So loving my enemies does not apparently mean thinking them nice either."
