An eccentric neo-positivist David Stove, an Australian, produced some great writing attacking western idealism (e.g. Plato and Kant) as well as the more egregious absurdities of marxism. Stove was a bit conservative (supposedly he was leftist in his youth), but seems materialist, more or less; his scathingly humorous attacks on postmod., marxism, feminism, etc. are sort of Jonathan Swift-like, but a bit more philosophically informed.
