evidence: Immanuel Kant[a] (born Emanuel Kant; 22 April 1724 – 12 February 1804) was a German philosopher and one of the central Enlightenment thinkers. Born in Königsberg, Kant's comprehensive and systematic works in epistemology, metaphysics, ethics, and aesthetics have made him one of the most influential and controversial figures in modern Western philosophy, being called the "father of modern ethics",[7] the "father of modern aesthetics",[8] and for bringing together rationalism and empiricism earned the title of "father of modern philosophy".[9][10] [...] Kant was baptized as Emanuel and later changed the spelling of his name to Immanuel after learning Hebrew.[13] He was the fourth of nine children (six of whom reached adulthood).[16] The Kant household stressed the pietist values of religious devotion, humility, and a literal interpretation of the Bible.[17] The young Immanuel's education was strict, punitive and disciplinary, and focused on Latin and religious instruction over mathematics and science.[18] In his later years, Kant lived a strictly ordered life. It was said that neighbors would set their clocks by his daily walks. He never married but seems to have had a rewarding social life; he was a popular teacher as well as a modestly successful author, even before starting on his major philosophical works.[19]
