William of Ockham, a Franciscan monk, a scholastic philosopher, and theologian used scientific logic to disprove Thomas Aquinas’s, Five Proofs for the Existence of God. Ockham held faith was a separate thing from science, stating that “God's existence cannot be deduced by reason alone.” At the time, this idea was socially repugnant forcing Ockham to spend the rest of his life in hiding. He continued to write about natural rights, politics and theology. He died in exile in 1347.
Ockham's Razor is the principle of parsimony that entities should not be multiplied beyond necessity. When theories compete in explanations, the simpler one is to be preferred. When arguing hypotheses about the same prediction, one should select the solution with the fewest assumptions.
