In 1764—1765, Kant found a new friend — an English merchant, a bachelor and a hermit Joseph Green. Kant's visits to him were always punctual, always at the same hour in the evening. With him, the philosopher discussed almost every sentence of the Critique of Pure Reason. It was from him that Kant took the idea of living «by the strictest rules or maxims» and introduced it into the thinking of a new human character.
