Schopenhauer was born on 22 Feb 1788 in Danzig -- his family were Dutch traders in the Hanseatic League, living in Danzig port city, at least until it was taken by Prussia, and then they moved on to another free trade town, Hamburg.
Schopenhauer believed that we live in a dual universe: the one that we perceive with our limited human senses and reasoning, and the universe as it truly is, which is unknowable and may or may not conform to our construct of “reason.” He was also pessimistic, believing that happiness is an illusion, our desires can never truly be satisfied, and the only way to attain peace of mind is by maintaining very low expectations. He was interested in Eastern religions and agreed with the Buddhist viewpoint that the nature of life is suffering, so happiness was simply freedom from it. His views on women influenced early feminists, who rejected his claim that women were childish and meant to obey. Schopenhauer never married.
He traveled often in France and England, considering himself an Anglophile even though he went to college in Gottingen and based in Berlin and Munich.
