Descartes & Locke: A Philosophical Discourse on Knowledge & Existence
Descartes: Doubt and the Criterion of Truth
Methodical Doubt
Doubt, for Descartes, is a method for reaching indubitable truth. It applies universally and involves three phases:
- Doubting the Senses: Senses often deceive us, making them unreliable.
- Doubting Immediate Experience: The dream hypothesis questions the reality of our perceptions.

Dialogue as a Way to Philosophize:
Plato followed his teacher Socrates, expressing their thoughts through dialogue as it was felt that while writings and speeches do not allow us to clarify the doubts and aporias (difficulties) they contain, dialogue, on the contrary, is a living form of philosophizing that plays the drama and the force of dialectic dialogue through questions and answers, clarifications, and rebuttals.

Aristotle (384-322 BC), Macedonia
Aristotle was first and foremost a naturalist and biologist devoted to the observation and study of nature. He tried to explain reality without recourse to the supernatural. Aristotle’s philosophy leaves the world of separate, transcendent ideas and focuses on the world witnessed by the real senses.
His main claim to fame is based on logic, the set of binding rules that allow the use of coherent discourse.
He was able to make the instrument (organon) of thought
