Darwinism is biological Kantianism. Darwinkantism? Kantarwinism?
The synthetic unity of species.
The historically transcendental features of lived experience. Noumenal selectionism?
The phenomenal manifestations of the noumenal limits of absolute biological constraints.
The ethical imperative not to act in a way that would have led to the extinction of your ancestors. The adaptive imperative?
If there is a way around Kantianism, then there is a way around Darwinism qua metaphysical "universal acid".
