# René Descartes — Philosophical Works character guide > René Descartes in Philosophical Works by René Descartes. **Role:** major **Also known as:** Descartes, La Vie de M. Descartes **First appearance:** 0000-discourse-on-the-method-of-rightly-conducting-one-s-reason-and-of-seeking-truth-in-the-sciences ## Snapshot The philosopher who surveys four ordinary roads to wisdom, finds no one has ever reached the fifth, and decides to try it himself. ## Who they are Descartes stands in a long line of thinkers — Plato, Aristotle, Epicurus — and judges them all to have failed at the one task that matters: finding first causes from which everything else can be deduced. His candor about that failure, and his willingness to begin again rather than defer to authority, is the engine of the whole project. He matters because he turns the history of philosophy into a challenge rather than a monument, inviting the reader to walk the untried road alongside him. ## In the story ### [Discourse on the Method of Rightly Conducting One’s Reason and of Seeking Truth in the Sciences](https://www.betterreads.dev/discover/philosophical_works_se/chapters/discourse-on-the-method-of-rightly-conducting-one-s-reason-and-of-seeking-truth-in-the-sciences) The author and protagonist, who develops and applies the method of doubt to establish certain knowledge. ### [Prefatory Note by the Author](https://www.betterreads.dev/discover/philosophical_works_se/chapters/prefatory-note-by-the-author) The author of the Discourse, who has discovered the method and deduced rules of morals and metaphysical foundations. ### [Discourse on the Method](https://www.betterreads.dev/discover/philosophical_works_se/chapters/discourse-on-the-method) The philosopher who systematically doubts all previous beliefs to find indubitable truth. ### [Meditations on the First Philosophy: In Which the Existence of God and the Immortality of the Soul Are Demonstrated](https://www.betterreads.dev/discover/philosophical_works_se/chapters/meditations-on-the-first-philosophy-in-which-the-existence-of-god-and-the-immortality-of-the-soul-are-demonstrated) The author who presents the Meditations, addresses objections from learned men, and demonstrates the existence of God and the immortality of the soul. ### [Dedication](https://www.betterreads.dev/discover/philosophical_works_se/chapters/dedication) Author of the treatise, seeking patronage and correction from the Faculty of Theology. ### [Preface to the Reader](https://www.betterreads.dev/discover/philosophical_works_se/chapters/preface-to-the-reader) Author and narrator, defending his philosophical method and responding to objections. ### [Synopsis of the Six Following Meditations](https://www.betterreads.dev/discover/philosophical_works_se/chapters/synopsis-of-the-six-following-meditations) Descartes is the author and central figure, outlining his philosophical method and arguments. ### [Meditations on the First Philosophy](https://www.betterreads.dev/discover/philosophical_works_se/chapters/meditations-on-the-first-philosophy) Descartes presents his philosophical arguments, including the wax example and the role of free will in avoiding error. ### [Meditation I: Of the Things of Which We May Doubt](https://www.betterreads.dev/discover/philosophical_works_se/chapters/meditation-i-of-the-things-of-which-we-may-doubt) The philosopher who authors the Meditations and is the subject of the narrative. ### [Meditation II: Of the Nature of the Human Mind;
