5+ Rationalism Books for Free! [PDF]

For you who want to know a little more about the philosophical current that seeks to explain the truth, we have created a collection of free books on rationalism in PDF format.

Rationalism promotes and sustains the self-sufficiency of reason to explain reality in a deductive way; it is a philosophical current that sponsors the primacy of reason to know the truth. 

This current began in the 17th century and the philosopher of French origin, René Descartes, is its main exponent; the movement, besides placing the problem of knowledge among the main themes, also emphasized the relationship between mind and body.

The most prominent representatives of this philosophical current lived in Germany, France, and other regions of Europe, and represented the opposition to the empiricism that emerged in England.

To learn the most relevant details of this current that marked a before and after in world history, you can consult the more than 20 materials between books and free articles on rationalism in PDF format that we share with you in this section.
