Key Philosophical Theories: From Aristotle to Ortega y Gasset

Philosophical Perspectives on Knowledge and Reality

Aristotle and the Desire for Wisdom

Text 26: Aristotle posits that humans have an innate desire to know, which becomes apparent when we lack sensory input. For the philosopher, this drive is a pursuit of wisdom—seeking to understand the most profound truths, not for practical utility, but for the sake of knowledge itself. In essence, the philosopher seeks to understand reality as a whole, which is the foundation of Metaphysics.

Descartes and the Role of Reason

Text 27: Descartes examines the reliability of the senses. He argues that because senses can deceive us, it is ultimately reason that allows us to attain an accurate understanding of reality.

Critique of Protagoras

Text 28: Aristotle critiques the assertion made by Protagoras that "man is the measure of all things."

Gorgias and the Triple Nihilism

Text 29: Gorgias expresses a triple nihilism:

• Ontological Nihilism: Nothing exists essentially; nothing is immutable.
• Epistemological Nihilism: Nothing can be truly known.
• Communicative Nihilism: Even if something existed and could be known, it could not be communicated, as knowledge remains trapped within the individual.

Ortega y Gasset: Perspectives and Truth

Text 30 & 33: Ortega y Gasset argues that true knowledge is universal, unique, immutable, and eternal. He suggests that every individual possesses a unique perspective, which is an essential ingredient of reality. Knowledge is the union and evolution of these subjective perspectives; therefore, universal knowledge is the sum of all individual viewpoints.

Augustine on the Pursuit of Truth

Text 32: Augustine asserts that every person prefers to know the truth rather than be deceived by madness. This aligns with Aristotle’s view, as both thinkers emphasize the human preference for truth over sensory deception.

Rationalism vs. Empiricism

Text 35: This text contrasts rationalism and empiricism. Rationalism, inaugurated by Descartes and inspired by Galileo’s scientific method, posits that mathematical thought is the sole source of reason. Conversely, empiricism defends the role of the senses as the primary source of true knowledge regarding reality.
