My contribution to Thinking Towards Humanity: themes from Norman Geras, Manchester University Press, 2012.
What is it like to be a blogger?
Hume famously observed that it is not contrary to reason to prefer the destruction of the whole world to the scratching of his finger. He wasn’t expressing a whimsically inflated sense of his own importance, but pointing out that logic doesn’t determine how we weigh the world versus our finger. We have to love the world in order to be able to weigh it properly. Looking it up in a table of weights and measures won’t do the job – we could see the arithmetic and still shrug and say yes but it’s my finger, the world is none of mine and I don’t care. We have to care in order to make choices properly – to make them in such a way that we don’t place our own petty desires above everyone else’s deepest needs. (We have been learning lately, if we didn’t already know, that bankers and investment wizards could use some intensive training in this.) Morality is rooted in feeling, Hume told us, and researchers such as Antonio Damasio and Jonathan Haidt have been elaborating on the idea recently.
