Descartes’ Method and Philosophy: A Deep Dive
Descartes’ Method and Philosophy
Text 1: Cartesian Method and Rules
Cartesian Method: Descartes’ reaction against skepticism, coupled with his interest in science, led him to emphasize error rejection and the search for truth. He insists on rejecting bugs in the pursuit of truth, preparing to investigate and determine anything with certainty, particularly in mathematics.
Definition of Method: A set of certain and easy rules, ensuring the discovery of true knowledge without vain effort, gradually increasing scientific understanding. The method serves to discover new truths, not prove existing ones.
Rules of the Method
1st Rule: Evidence as Criterion of Truth
Accept nothing as true unless evident. Clarity and distinction are key. Reject preconceived ideas and judge only what is clear and distinct. This combats ingrained notions from childhood that obscure natural understanding. Three precepts emerge: (1) Judge only with clear evidence. (2) Avoid preconceptions. (3) Judge only based on clear and distinct perceptions.
2nd Rule: Divide and Conquer
Divide each difficulty into smaller parts for examination and solution. This represents the final stage of analysis and synthesis.
3rd Rule: Orderly Thought
After dividing difficulties into simpler natures, conduct thoughts in an orderly manner.
4th Rule: Comprehensive Review
Ensure all reasoning links are sound to prevent errors from memory weakness. This reflects rationalist optimism, suggesting everyone possesses the same reason, fostering optimism if used well.
Text 2: Method of Mathematics
Method: Relates to the mathematical argument.
Text 3: Implications and God’s Existence
Implication: The fourth part of the method establishes the existence of God and the human soul through causal arguments. Philosophy is based on demonstrating God’s existence. Discarding the cause of all (sensible world, ideas, etc.), Descartes discusses God’s existence. He concludes that God cannot be a composite being since nature is distinct from the body. Composition implies dependence, and dependence implies imperfection.
Idea: A picture or representation of a thing. Ideas are neither true nor false; truth and falsity apply only to judgments. Ideas have two aspects: (a) Formal reality (being thought), where all ideas are equal. (b) Objective reality (representing things), where ideas differ. Some ideas are innate, others adventitious (external), and others factitious (invented).
Descartes attributes characters to a substance, leading to the concept of a “thing” with attributes. The existence of external things remains a question. Analysis of the “I think” characterizes it as a thinking substance.
Three types of ideas exist: (1) Adventitious (external). (2) Factitious (invented). (3) Innate. Descartes analyzes ideas of infinity and perfection, arguing they cannot originate from a finite and imperfect being like himself. These ideas must be placed in him by an infinite and perfect being—God. Thus, Descartes proves God’s existence through arguments based on the ideas of infinity and perfection.
