Rational philosophy emphasizes the use of reason and logical thinking to understand the world and human existence. It seeks to establish knowledge through rational arguments rather than relying solely on sensory experience or emotional responses. Key figures in this tradition include René Descartes and Immanuel Kant, who explored the foundations of knowledge and the nature of reality. This approach often contrasts with empiricism, which prioritizes observation and experience. Rational philosophy has influenced various fields, including science, ethics, and political theory, by promoting critical thinking and systematic analysis as essential tools for inquiry and understanding.
