Additionally, Bahnsen disagreed with Hartmann on fundamental points. If the will and the (rational) ideas are different (as Hartmann claimed), how do the Ideas influence the Will at all if they don't have a will of their own? Hartmann would claim that they are "different, yet unified", staying true to his monism. Yet, this would appear as a contradiction to Bahnsen and would further solidify the power of Bahnsen's own convictions and conclusions stemming from his "Realdialektik". As for Hartmann, he did not accept Bahnsen's theories and diagnosed him with a "psychopathic melancholy" and a philosophical inability to distinguish "conflict" from "contradiction".
