Context

“It therefore shows entire ignorance of the problem, or at least it is very inept, to wish to define that relation as that between being and thinking. Thinking has primarily only a relation to perceiving, but perception has a relation to the real being of what is perceived, and this last is the great problem with which we are here concerned. Empirical being, on the other hand, as it lies before us, is nothing else than simply being given in perception; but the relation of the latter to thinking is no riddle, for the conceptions, thus the immediate materials of thought, are obviously abstracted from perception, which no reasonable man can doubt. It may be said in passing that one can see how important the choice of expressions in philosophy is from the fact that that inept expression condemned above, and the misunderstanding which arose from it, became the foundation of the whole Hegelian pseudo-philosophy, which has occupied the German public for twenty-five years.” source
