Truth Versus Interpretation

Kant: Experience and Knowledge

I wonder, how did Kant encounter the idea of a noumenal world containing differential perceptions and conceptions if it is said to be a realm that is beyond human comprehension or expression? If we are ignorant of this realm and the true nature of its contents, how do we acquire knowledge about it? According to Kant, we acquire knowledge of this ineffable domain, "the (presumed) things themselves, which constitute reality," through experiences of the phenomena-"appearances, which constitute the our experience". The only a priori judgments (judgments that are independent of observation or experiences and based entirely on an entity's true nature, unattainable by the human race) that we can make must derive from experiences in the phenomenal realm. Kant believed that the laws of nature, science, and mathematics are apprehensible exclusively because they intend to explain the world as we experience it. What is the true nature of a pencil? Surely, it is more than the words we produce with it and the smell of its shavings, but these experiences are the only things that will define a pencil's purpose to us. Experience truly is the only way we can attain knowledge. If we could comprehend the world as it is in the noumenal realm, then life would be utterly inane. I think it's safe to say that perspectivism is relevant in terms of radical constructivism. We must perceive the same things (from the noumenal world), yet interpret them differently based on experience in the phenomenal realm which we are familiar with. We can contrast radical constructivism with metaphysical realism even further by suggesting that radical constructivism is creation and interpretation based on experience while metaphysical realism is interpretation of a description. A skeptic would ask how Kant discovered the idea of Noumena if it isn't accessible to mankind. It's possible that a radical constructivist would suggest that we could create that access and possibly merge the two realms together, bridging the gaps between truth versus perception and description versus interpretation. Exactly how, whether consciously or by means of an inconceivable inner force, we could achieve this, is another question.
