Descartes and Spinoza: Rationalism, Method, and Substance
Descartes’ Method: A Foundation for Rationalism
Descartes believed the success of his method stemmed not only from its inherent perfection but also from his understanding of human reason as a faculty capable of addressing and resolving complex questions. His method is based on four rules:
- Evidence: Accept only what is clear and distinct.
- Analysis: Divide complex problems into simpler parts.
- Synthesis: Systematically build from simple to complex.
- Enumeration: Thoroughly review to ensure nothing is omitted.

A common critique of Marxism targets its idealist philosophy. Marxist thought posits that all

Thus, considering that our senses

Justice in Plato’s Philosophy
Justice: Virtue consists in the hierarchical, orderly, and harmonious arrangement of the three parts

In the first part of Discourse on Method, René Descartes addresses the issue of methodology, which is able to establish, manage, and organize existing ideas and guide the search for truth, discerning what is true or false, and what constitutes common sense or reason.
Faced with a rigorous education at the Jesuit school La Flèche, based on the principles of Scholastic philosophy (considered the most valid defense of the Catholic religion), Descartes felt confused and dissatisfied by the lack of
