David Hume’s Philosophy: Knowledge, Causality, and Substance
David Hume
Theory of Knowledge
Hume defined perception as everything that is present in our minds, and he identified two types:
- Impressions: Knowledge gained through the senses.
- Ideas: Representations or images of perceptions in thought, which are derived from impressions and are less intense.
Impressions serve as the criterion of truth for ideas because an idea is true if we can identify it as coming from an impression. Hume also distinguished two ways of knowing:
- Knowledge of relationships among ideas

Becoming
Becoming is often used synonymously with evolving. Some conceptions of becoming include:
- The Eleatic solution: Seeking to account for evolution through denial.

- The Heraclitean solution: Proclaiming that reality is, in essence, becoming.
Nietzsche understood the history of philosophy very well and considered that becoming was incomprehensible to reason. Therefore,

Plato’s Concept of the Soul and Reminiscence
Plato, building upon the Socratic thesis of anamnesis, argues for the immortality of the soul. Anamnesis suggests that learning is a form of recollection. Socrates addresses the question of dualism, asserting the soul’s superiority over the body. He posits that humans are composed of a divine and immortal part (the soul) and a corruptible, mortal part (the body). The soul resembles the divine and immutable, while the body is subject to change.

Epicureanism and Stoicism: Two Ancient Philosophies
Epicureanism: A Philosophy for a Happy Life
Epicurus (341-270 BC) was born in Samos and lived in Athens. His conception of the good and optimal human behavior differed greatly from Aristotle’s political vision. Epicurus advocated for the affirmation of the individual and their conscience as the core of morality.
Epicurus conceived philosophy as a way of life. Epicureanism, rather than being a rigid philosophical system, is a practical approach to living. Epicurus’s thought is based on three fundamental

Aristotle’s Hylomorphism: Matter and Form
Hylomorphism is the Aristotelian theory that states everything is composed of matter and form:
- Matter: The substratum of form.
- First matter: The absolutely unknown substrate in the composition of all material things.
- Second matter: The tangible reality. Example: wood.
- Form: What determines the matter.
- Substantial form: What makes a thing what it is. Example: table.
- Accidental form: Accidents of second matter. Example: color of the table.
