Every worldview claiming eternal truth is actually historically provisional.

Evidence

If the philosophy of praxis affirms theoretically that every “truth” believed to be eternal and absolute has had practical origins and has represented a “provisional” value (historicity of every conception of the world and of life), it is still very difficult to make people grasp “practically” that such an interpretation is valid also for the philosophy of praxis itself, without in so doing shaking the convictions that are necessary for action. This is, moreover, a difficulty that recurs for every historicist philosophy; it is taken advantage of by cheap polemicists (particularly Catholics) in order to contrast within the same individual the “scientist” and the “demagogue”, the philosopher and the man of action, and to deduce that historicism leads necessarily to moral scepticism and depravity. — Antonio Gramsci, Selections from the Prison Notebooks, 1442

Categorization

• DEFINE: This defines the historicity thesis at the heart of the philosophy of praxis — that even Marxism’s own claims are provisional, creating a self-referential problem.
• XREF: The historicity-of-all-worldviews claim connects to Foucault’s genealogy and the later construction-of-the-Other vocabulary the Islamophobia toolkit needs.
