Rationalism

Definition

Rationalism is a philosophical viewpoint that emphasizes reason as the primary source of knowledge, asserting that certain truths can be known through intellectual deduction rather than sensory experience.

In contrast, empiricism argues that knowledge comes from sensory experiences and observations. While rationalists prioritize logical reasoning as the basis for understanding reality, empiricists emphasize experimentation and evidence as essential for validating knowledge claims. This debate between the two philosophies shaped various fields including science, philosophy, and education during the Enlightenment.
