“…then there is an end to the Kantian ungraspable ‘thing-in-itself’. The chemical substances produced in the bodies of plants and animals remained just such ‘things-in-themselves’ until organic chemistry began to produce them one after another, whereupon the ‘thing-in-itself’ became a thing for us — as, for instance, alizarin, the coloring matter of the madder, which we no longer trouble to grow in the madder roots in the field, but produce much more cheaply and simply from coal tar.” (Ludwig Feuerbach and the End of Classical German Philosophy)
“For us” is a relation of cognition. “For-itself” names the object’s determinate self-relation. Cognition can grasp that self-relation, and it is the intention of philosophy to bring its positive Content to light, and develop thought into reflexive conceptual knowledge.
