Historical Materialism is the application of Marxist science to historical development. The fundamental proposition of historical materialism can be summed up in a sentence: "it is not the consciousness of men that determines their existence, but, on the contrary, their social existence that determines their consciousness." (Marx, in the Preface to A Contribution to the Critique of Political Economy.)
What does this mean? Readers of the Daily Mirror will be familiar with the "Perishers" cartoon strip. In one incident the old dog, Wellington wanders down to a pool full of crabs. The crabs speculate about the mysterious divinity, the "eyeballs in the sky," which appears to them.
The point is, that is actually how you would look at things if your universe were a pond. Your consciousness is determined by your being. Thought is limited by the range of experience of the species.
