Kant's Transcendental Idealism

Kant's transcendental idealism suggests that we do have experiences of things in the world that exist. We might not be totally tuned to what they are truly in themselves as numina, and we might never. In fact, we will never. But we can still accept the fact that we are having a relationship with those things as phenomena. And we can still extract certain truths, empirical truths within the world, from these phenomena that can extend beyond those things themselves.
