• B. David Hume
• C. René Descartes
• D. John Locke

Answer: (C)

René Descartes is often referred to as the "Father of Modern Philosophy" due to his significant contributions to the development of Western philosophical thought. His statement "I think, therefore I am" encapsulates his approach to epistemology and his quest for foundational knowledge. This phrase, originally "Cogito, ergo sum," emphasizes the act of thinking as proof of one’s existence and is central to his philosophy.

In his works, Descartes sought to establish a new method of inquiry based on reason and doubt, departing from reliance on tradition and sensory experience. By starting with doubt and arriving at certainty through rational thought, he laid the groundwork for modern philosophy and influenced various fields, including mathematics and science. His emphasis on the use of reason as a path to knowledge set a precedent that shaped the landscape of philosophical inquiry for centuries to come.
