Plato would hardly need to change a single word of his myth of the cave. Our knowledge would not be able to furnish an answer to his anxiety, his disquietude, his "premonitions." The world would remain for him, "in the light" of our "positive" sciences, what it was - a dark and sorrowful subterranean region - and we would seem to him like chained prisoners. Life would again have to make superhuman efforts, "as in a battle," to break open for himself a path through the truths created by the sciences which "dream of being but cannot see it in waking reality." [1] In brief, Aristotle would bless our knowledge while Plato would curse it.
