The opening paragraph of that shows considerable ignorance of the actual history of mathematics (and misrepresenting History is a sin for a Marxist, no?) --

Consider that calculus too started out as a half-baked theory laden with paradoxes, and that one of the great mathematical achievements was to put it on a rigourous footing. And indeed, set theory was one of the important tools in that enterprise.
