How René Descartes might approach Philosophy

For too long has that noble pursuit known as philosophy been a fertile ground for dispute and uncertainty, a edifice built upon shifting sands rather than solid rock. Indeed, when I reflect upon the vast array of opinions held by various learned men, concerning even the most fundamental questions, I find myself overwhelmed by a profound skepticism. How can we call this knowledge, when it lacks the very certitude we demand of arithmetic or geometry? It is evident that if we are to establish anything firm and lasting in the sciences, we must first demolish these questionable foundations and begin anew.

My method is this: to doubt everything that can possibly be doubted, to reject as absolutely false anything in which I could imagine the least reason for doubt. I examine all I once believed, not as a madman, but as one committed to truth alone. The senses, I have observed, often deceive us. Our imaginations conjure illusions. Even the most seemingly clear propositions might be the trick of an evil genius.

Yet, in this very act of doubting, I discovered an indubitable truth: I, who was doubting, must exist. Whether I am deceived or not, I cannot be nothing. *Cogito, ergo sum* – I think, therefore I am. This single, simple proposition, perceived with such clarity and distinctness by the natural light of reason, forms the Archimedean point, the unshakable foundation upon which all true philosophy must be erected.

From this first truth, and guided by the same principle of clear and distinct perception, I proceed, as one would in geometry, to deduce the existence of a perfect God, who guarantees the truth of what I clearly and distinctly perceive. From there, I advance to the existence of the material world. Thus, from the inner certainty of the thinking self, we may…
