"Those attracted to nominalism usually seek to press it as far as it can go, and understandably so. For if one's nominalism is motivated by a desire to defend materialism or naturalism, there isn't much point to being selective about it, since to admit that at least some sorts of abstract (hence non-material and non-natural) objects exist seriously weakens the plausibility of materialism or naturalism as a general position."
--Edward Feser, The Last Superstition, 2008, 274-275.
