The Cartesian method, also known as the discourse of the method, is one that consists of the application of a methodical doubt, that is, it is about doubting all or any truth that is displayed in front of our senses in order to recognize the truths that tolerate methodical doubt, which are those greater truths on which an idea of reality must be erected. And it is in this way that the Cartesian method works by promoting or promoting the doubt that lies in each of the sensible realities by proving the unconsciousness of all the individual's senses. And when this happens, doubting all these sensible realities, only all those internal geometric and mathematical realities remain standing.
The method of discourse was devised by the French philosopher, mathematician and physicist Rene Descartes, also known as the father of analytical geometry and modern philosophy, in the year 1637 published in Leiden, the Netherlands, to later be translated into Latin and published in 1656 in Amsterdam, with the purpose of directing the reason well and finding the truth in the sciences. The Cartesian method is one of the most respected and accredited works in the history of modern philosophy, in addition to being of great importance for the evolution of natural sciences. Rene Descartes in this speech touches on the theme of skepticism, which was previously studied by Sexto Empirico, Al-Ghazali and Michel de Montaigne.
This method can be applied to different topics or questions, and has only four important rules, which are:
1. Rule of evidence, nothing is admitted as true unless it is evident.
2. Rule of analysis, divide the problem into different parts, to more easily solve what is being studied
3. Rule of synthesis, once all the parts are studied, a synthesis is made, a pooling of everything that we have obtained by studying the different parts.
4. Rule of checks, at the end of the synthesis, list everything and review it in case something is omitted.
