BLAISE PASCAL (19 June 1623 - 19 August 1662) was a French mathematician, physicist, inventor, writer and Christian philosopher. He was a child prodigy who was educated by his father. On 23 November 1654, between 10:30 and 12:30 at night, Pascal had an intense religious vision and immediately recorded the experience in a brief note to himself which began: "Fire. God of Abraham, God of Isaac, God of Jacob, not of the philosophers and the scholars..." and concluded by quoting Psalm 119:16: "I will not forget thy word. Amen." He seems to have carefully sewn this document into his coat and always transferred it when he changed clothes. Following this experience, he began writing influential works on philosophy and theology. His two most famous works date from this period: the Lettres provinciales and the Pens es. Pascal had poor health, especially after his 18th year, and his death came just two months after his 39th birthday.
