The major works
Kant was 57 when he published the Critique of Pure Reason — then, within some fifteen years, one work followed another. Each writing has its own page here covering genesis, core theses and impact.
Every work page has a Kant decoder: a famous sentence (German original plus our close translation) that you unpack in three steps, from its frame through the key words to a plain-language version.
