Will Wright argues that scientific knowledge - and specifically physics, as the fundamental science - is primarily an effort at social legitimation, and that its conceptual incoherence as knowledge is now becoming ecological incoherence as social practice. In this argument he attacks the scientific notions of nature, mathematics, the mind and social life, and concludes that the idea of knowledge must be understood ecologically and reflexively as an issue of language, rather than objectively and technically as an issue of nature.
