Descartes’ Epistemology: Understanding His Theory of Knowledge
Descartes’ Epistemology: Theory of Knowledge
Descartes had a great interest in thinking about man, the self, and introspection. Everything started from scratch as a result of discovering errors in established knowledge. Heliocentrism, showing the existence of an infinite universe without a center, conditioned philosophers to review all criteria of truth. This period of doubt caused great confusion and uncertainty, leading to the school of thought known as Rationalism. Its main features are:
- Reason
Kant’s Critical Philosophy: Reason and Science
Critique of Reason: Understanding its Limits
Abstract: The direction of a critique of reason itself is the task to prosecute the fundamental reason for the discrepancy and resolve the antagonism between their performances:
- Rationalist dogmatism, with its pretension that reason alone can interpret the structure and the sense of all that is real.
- Empiricist positivism, whose ultimate expression is skepticism, an attempt to reduce thought given by the senses, thus defeating reason.
- Irrationalism, understood

Plato’s Dualism
Dualism: Plato: Plato viewed all that we can touch and feel in nature as constantly changing. He believed the world consists of a field that is always in flux.

The Cogito and the Criterion of Truth
Doubt, disappointment, and disorientation are the results of years of study. The solution is contained in reason: it is one and the same for all men and their proper use. The method will also be one and the same for all sciences. The philosophical foundation of the method will doubt; it can reach the indubitable truth. There is no doubt that skepticism denies any possibility of knowledge, but it is the methodical starting point for an investigation. This is a
