The term 'Father of Modern Philosophy' refers to Renรฉ Descartes, a French philosopher whose ideas and method of systematic doubt laid the groundwork for modern Western philosophy. His emphasis on reason, skepticism about accepted truths, and the famous dictum 'Cogito, ergo sum' ('I think, therefore I am') revolutionized philosophical thought, influencing various aspects of the Enlightenment, cultural shifts in the 18th century, colonial rivalries, and the transformation of scientific inquiry.
