Kant fought against metaphysics because he saw it as a primary source of unbelief and immorality. Really.
I have therefore
found it necessary to deny knowledge, in order to make room
for faith. The dogmatism of metaphysics, that is, the precon-
ception that it is possible to make headway in metaphysics with-
out a previous criticism of pure reason, is the source of all that
unbelief, always very dogmatic, which wars against morality.
This is no chance remark, but a certain summary of the whole Kantian project. With the benefit of hindsight, we can see this is as purely accidental. Metaphysics was never the real enemy. In truth, immorality alone, or the perverse will of an immoral man- is the primary enemy of morality, and it will justify itself and beat on morality with the any stick at hand. If people respect science, immoral people will use science against morality; if people respect literature, the immoral will fight against morality with literature; if politics, politics; if tribal gods…. whatever. Examples of this abound. Honestly, Kant’s hang up with metaphysics strikes me a hilarious. Has the empirical science that Kant so loved proved itself any more of a friend to morality? Of course not.
A similar silly opinion to Kant’s is sometimes found in postmodern thought. The idea is that it was the belief in ones own certitude that led to all the atrocities of the twentieth-century, as opposed to this being properly and primarily due to perversity and obstinance in wickedness. Stalin killed millions because he was so sure of his system. Hilarious. Postmodern thought can kill as many out of its skepticism as Hitler killed with his certitude. This is the dark side of the axiom “where there’s a will there’s a way”
Just Thomism
