Here is some info on the incompleteness theorem:
Gödel's incompleteness theorems - Wikipedia, the free encyclopedia
I dont say that science dosnt lead to increased knowledge of the Universe, but it relates that knowledge in the form of myth, or perhaps "metaphor" is a term that you would find less offensive. Im a spiritual person, but my argument is not an attempt to make space for a God, its siomply a recognition that language is limited.
Perhaps I should say Marxists, rather than Marxism?
Anyway, part of the problem is that the early Marx is quite different from the later Marx; another part is that theoretical Marxism can be considered to be distinct from what we might term 'political' Marxism. Socialism is at times portrayed as a normatively desirable goal, and at times as a consequence of the operation of deterministic historical laws, with no normative content.
Science is not restricted to language. There is mathematics and physical experiment. Why do you say it relates to knowledge in the form of myth? I thought you accepted that the development of thought through natural selection was an evolutionary advantage ? That would only be the case if thought allowed for accurate reflection of nature and the development of knowledge that enabled us to survive more effectively in the material world.
I'll read your link: here is one from Lenin:
Lenin: 1908/mec: 1. Sensations And Complexes Of Sensations
Have you read Diderot on idealism ? Historically, idealist philosophy of the kind you and stringjack espouse was intended to counteract the materialism of the Enlightenment - it was a reactionary tendency both philosophically and politically.
