This objection is often summed up under the slogan of “deducing Krug’s pen”, in that in 1801 the philosopher W.T. Krug had accused Schelling’s idealist philosophy of nature of aiming to deduce the nature of all contingent phenomena, even that of the pen with which he, Krug, was writing his critique. Hegel responded to Krug’s accusation in the following year, claiming that Krug had made the common mistake of conflating the understanding with reason, and treating the Absolute as something on the same level as finite things.
