The Philosophy of Kant Pt.1

Immanuel Kant was born in Honisberg in 1724, and was brought up in a Pietistic family. His earliest influences were Newtonian physics and his philosophy professor, Professor Knutzen. He is know to have first formulated the nebular hypothesis (that the universe was at one time a primitive cloud), but it is debated that it was in fact Emanuel Swedenborg who first proposed this. Kant was a believer in the natural law, an idea he took from Aristotle, and used the idea that humans are logical and rational by nature in his philosophy. To the questions he thought were out of reach and unanswerable, he called this the use of ‘speculative’ reason, a part of our reason which desires to know that which is not knowable, so speculates about answers without any real rational argument to support them. Kant described his Critique of Pure Reason as the ‘Copernican Revolution’, since he set out to show that the mind is like a solar system.

Kant rested upon the assumption that truth is stable, and that logic is perfect and complete. He took the Platonic idea that concepts are greater than what is physical and built on it. A lot of his work rests on the concept S is P. S is the subject, and P is the predicate or quality (e.g. the sky is blue). This will be developed later.

Kant rejected empiricism, a philosophy made famous by David Hume, which proposed that causality does not exist, and that it is our own subjective minds which make the mistake of assuming cause and effect: aRb where R is psychological and subjective, and represents the idea of causality. Kant rejected this, as well as Locke’s idea of a ‘tabula rasa’, arguing that logic and rationality are imprinted into us before we are born. This too will be developed later.

Kant is perhaps most famous for his development on Hume’s ‘relations of ideas and matters of fact’. Kant formulated the idea of analytic and synthetic judgements. Analytic judgements don’t tell us anything new (e.g. a bachelor is an unmarried man)-they are true but uninformative. All analytic judgements are a priori. Synthetic judgements are informative and can be either a priori (universal, necessary, and before experience-7+5=12) or a posteriori (after examination-sky is blue). Kant’s idea of S is P is resurrected here. S=intuitions, and are experienced through the faculty of sensibility. P=concepts, and the faculty of understanding is responsible for concepts.
