The Latin phrase "Cogito, ergo sum" is often translated as "I think, therefore I am." Coined by the renowned philosopher René Descartes, it encapsulates a foundational principle in philosophy. The phrase suggests that the very act of thinking is evidence of one's existence. Descartes employed this statement as a fundamental starting point for his philosophical investigations, aiming to establish a firm foundation of knowledge. It underscores the inseparable connection between consciousness, rationality, and self-awareness, inviting profound contemplation on the nature of existence and the role of thought in affirming our reality.
