A number of years ago I created this picture in an attempt to explain Kant’s model of understanding (initially to myself). Was it possible to encapsulate its sheer extent and subtlety in one image? The obvious answer - a relief to lifetime Kant scholars - is a resounding “no”, but something about this conveys at least some of its essence, in my humble opinion.
What is shown serves as a quick aid memoire that summarises the hours of podcast lectures and notes supporting reading of the text, but cannot survive as standalone elucidation.
It occurred to me that providing some text alongside would help place all this in context, and help distill thoughts into something of a lecture template. If you want to learn something ,teach it. So as understanding evolves so will this essay, and if it helps anyone grasp at any level perhaps the most famous and least understood philosophical treaty then I’ll take that as a win.
Kant’s philosophy grew from the reconciliation of two competing approaches: rationalism and empiricism. The rationalist tradition tackled philosophical problems through thought alone, believing that the right person in the right armchair could deduce the rules and facts of the world. Clearly this is impossible. As humans have often learned, the real world can often be counter to our intuitions, and so requires objective observation to observe facts of the world, and allow them to direct you to rules and theories that can be further tested with other observations. Radical empiricists believed that knowledge was acquired entirely in this way, through exposure to experiences through the human senses. Kant’s problem with this was the belief that if all we receive is the experience of senses then where do the rules and laws of nature come from. He reasoned that there must be some facets of knowledge that come from humans themselves, not necessarily the content of knowledge, but its structure.
