"Meditations on First Philosophy" (René Descartes)

"Meditations on First Philosophy" is a philosophical work by René Descartes, where he seeks to establish a foundation for knowledge. Descartes systematically doubts all beliefs to find what is undeniably true. He famously concludes, "I think, therefore I am," affirming that the act of thinking signifies existence. Throughout the meditations, he explores the nature of reality, the existence of God, and the distinction between the mind and body. Ultimately, Descartes aims to demonstrate that certain knowledge is achievable, laying groundwork for modern philosophy and science by promoting skepticism and clear reasoning as tools for understanding truth.
