This agreement between Kant and Hume must at first sight surprise us, when we recall that, as already mentioned, Kant worked out his philosophy precisely to protect the cognizing being of man from the consequences of Hume's thought. For, as he himself said, it was his becoming acquainted with Hume's Treatise that 'roused him out of his dogmatic slumber' and obliged him to reflect on the foundations of human knowing. We shall understand this apparent paradox, however, if we take it as a symptom of humanity's close imprisonment in recent centuries within the limits of its onlooker-consciousness.
