What is the rationalism belief fact?

Rationalism is the philosophical belief that reason and logical deduction are the primary sources of knowledge, rather than sensory experience. Rationalists argue that certain truths can be known through intellectual insight alone, independent of empirical evidence. This perspective emphasizes the role of innate ideas and principles, suggesting that some concepts are inherent to human understanding. Key figures in rationalism include René Descartes, Baruch Spinoza, and Gottfried Wilhelm Leibniz.
