Answer:
What was Blaise Pascal known for? Blaise Pascal laid the foundation for the modern theory of probabilities, formulated what came to be known as Pascal's principle of pressure, and propagated a religious doctrine that taught the experience of God through the heart rather than through reason.
Pascal's sudden religious conversion, probably the most decisive moment in Pascal's personal life, during the night of the 23rd to 24th of November 1654, was accompanied by a lighted vision which he interpreted as fire which brought him the total conviction of God's 'reality and presence'.
