 Boole’s final path to logic fame occurred in a curious way. In early 1847 he was stimulated to renew his investigations into logic by a trivial but very public dispute between De Morgan and the Scottish philosopher Sir William Hamilton (1788–1856)—not to be confused with his contemporary the Irish mathematician Sir William Rowan Hamilton (1805–1865). This dispute revolved around who deserved credit for the idea of quantifying the predicate (e.g., All \(A\) is all \(B\), All \(A\) is some \(B\), etc.). MaryAnn wrote that when the true method flashed upon him in 1847, “he was literally like a man dazzled with excess of light”.  Within a few months Boole had written his 82 page monograph, Mathematical Analysis of Logic, first presenting an algebraic approach to Aristotelian logic, then looking briefly at the general theory. (Some say that this monograph and De Morgan’s book Formal Logic appeared on the same day in November 1847.)
