Metaphysics: Reality, Existence, and Belief
Plato: The Reality of Ideas
In the fourth century BC, Plato proposed one of the most important metaphysical systems.

The Essence of Ratio-Vitalism
Life as a Paradox
If life is defined by our choices, then it is a constant state of becoming. We project ourselves into the future, anticipating what we will be. This forward momentum makes us aware of our existence as temporal beings.
The Vital Reason as Historical Reason
Ortega y Gasset’s ratio-vitalism emphasizes the interconnectedness of reason and life. Human existence, he argues, can only be understood through the lens of reason. This creates a synthesis between

Rationalism: From Descartes to Spinoza
Rationalism
Rationalism posits the self-sufficiency of reason as the primary source of knowledge, contrasting with empiricism, which emphasizes sensory experience. While empiricism asserts that knowledge comes from experience, rationalism argues that valid and true knowledge about reality proceeds from reason. Science, ideas, and principles, according to rationalists, originate from innate ideas within the understanding, existing independently of experience. Rational knowledge is inherently trustworthy,
