Jean-Jacques Rousseau: Enlightenment and Romanticism

Jean-Jacques Rousseau (Geneva, 1712) developed theories that served as a bridge between the Enlightenment and Romanticism. His political ideas heavily influenced the French Revolution and the growth of nationalism. His legacy as a radical and revolutionary thinker is captured in two famous sentiments:

• "Man is born free, but everywhere he is in chains."
• "Man is good by nature."

These concepts laid the foundation for his theories on education.

The Enlightenment and the Age of Philosophers

The Enlightenment flourished in France, where Voltaire promoted Anglophilia and championed the encyclopedic movement. This intellectual shift also bore fruit in Britain and the American colonies, shaped by the sociopolitical...

Theory of Ideas

The realities of ideas exist independently of the characteristics of things. Plato places them in the tradition of Parmenides, asserting that they are unique, eternal, immutable, and unchanging, and can only be grasped by intelligence. Things, on the contrary, are multiple and subject to change.

Objectives of the Ideas

• Ethics: To fight sophistic relativism, Plato bases virtue on knowledge; one can only be fair if one knows the idea of justice.
• Politics: Rulers must be guided by absolute ideals.
• Scientific: Science can only discuss what is permanent. Since the sensible world is constantly changing, science can only exist regarding the world of ideas.

The Platonic Soul

The soul is the reality intermediate between the two worlds. Plato...

Historical and Geographical Context

The basic framework of Greek life was the polis, the city-state. An essential part of the polis was the agora, a meeting place for citizens. Throughout this period, the pressure of the Persian Empire was constant.

Fundamental Social Changes

These changes questioned the traditional view of the world and paved the way for philosophical inquiry:

• The emergence of the hoplites (foot soldiers), changing the traditional model of war and replacing the Homeric hero.
• The emergence of alphabetic writing and the introduction of currency restructured traditional mental space.
• The emergence of a new commercial class brought new approaches and new values. New skills were needed that myth could not provide.

The polis of Miletus,...

Defining Reality: Material and Spiritual

Philosophers distinguish two types of reality: material and immaterial (or spiritual). The relationships proposed between them include:

1. Exclusion: The existence of one kind excludes the existence of the other (characteristic of metaphysical materialism or spiritualism).
2. Coexistence: They may interact, but interaction is considered very difficult as they are radically different.
3. Basis: One reality serves as the foundation or basis upon which the other is built.

Plato and Aristotle: Foundational Views

It is sometimes argued that Plato resolved fundamental philosophical issues, with later philosophers primarily commenting, nuancing, and explaining his work. Aristotle (often associated with a more material perspective)...

The Transition from Myth to Logos

Starting in the 6th century BC, particularly in regions like Greece, a new form of rational thought emerged. This shift challenged traditional cultural, political, and religious dogmas that previously forbade questioning mythological explanations. This new method, known as Logos, is characterized by:

• Justifying and arguing every affirmation.
• Utilizing logic.
• Maintaining a critical attitude.

Understanding Mythological Thinking

Before the rise of Logos, Myth provided the primary explanations for the existence of the universe and human behavior. Mythological thinking is defined by:

• Narrative structure: Myths are stories that do not require justification; they are accepted as truth.
• Anthropomorphic analogy: Using images

Philosophy is an activity that reflects on concepts. It involves examining concepts without preconceived notions and responding with arguments or reasoning, similar to Aristotle's approach. According to him, the origin of philosophy lies in the admiration for strange phenomena that we don't understand by nature or because we lack instinctive explanations. Explanations can be:

• Pre-rational: Myths are explanations based on imagination. These fantasy stories tell of supernatural beings and random events.
• Rational: These explanations originated in Miletus (6th century BC) due to its geographical location and commercial activity. The rise of democracy in Miletus contributed to the development of rational reasoning.

Types of Rational Explanations:

• Scientific

The Eudaimonist Ethics of Aristotle

Plato imagined the existence of an ideal, eternal, and immutable Good, illuminating the intelligible world. Aristotle, however, takes a position similar to that of Plato's disciples with respect to the Good. Similarly, the Good is not one thing, but a multitude of goods.

There exists not one good, but a multitude of goods.

So if in any case Aristotle holds that whatever is natural to a thing tends toward its good, it permits that thing to achieve a higher grade of perfection in its being.

The highest good, if it exists, according to Aristotle, must possess certain characteristics that allow us to recognize it:

• It must be valuable in itself, and not only as a means to reach another good.
• It must be sufficient in

The Sensible and Intelligible Worlds in Plato's Philosophy

The Relationship Between the Sensible and Intelligible Worlds

Plato explores the connection between the sensible (perceptible) and intelligible (conceptual) realms through several key ideas:

1. Participation: Ideas are fundamental beings, and physical things gain their existence by participating in these ideas.
2. Imitation: Physical things are created by a Demiurge (divine craftsman) who imitates the eternal Forms or Ideas.
3. Purpose: Ideas serve as the cause of all occurrences, as things strive towards a soul-body ratio idea.

Soul and Body

The union of the soul and body is considered accidental and superficial, with the body acting as a prison for the soul. Plato views the body as an impediment,...

Science and Episteme

SCIENCE: episteme — justified knowledge; a foundation that provides reason whether something is true. Mathematics, astronomy and music are the sciences, but the knowledge of the Good is not the same kind of science. If the Good were merely based on science, then science would be nothing unless it were directed toward achieving the good.

Intelligible Realm

AMBITO INTELLIGIBLE: the world of ideas, the field that concerns the predicate of being — the really real — because it is imperishable and immutable. It can only be seen or known by intelligence (nous) and is beyond what is immediate.

Sensible Realm

AMBITO SENSITIVE: the world of things: the changing and changeable world that is immediately before us in the eyes and senses....

Philosophy of Aristotle

Aristotle was a disciple of Plato and the teacher of Alexander the Great. At the age of 18, he entered Plato's Academy, remaining there until Plato's death, after which he founded his own school, the Lyceum. His work relates to the philosophies of Parmenides and Heraclitus (providing a solution to their antinomies) and Plato (transcending Platonic dualism by valuing sensible being and rejecting the theory of Ideas, searching instead for the universal as the essence of things).

Metaphysics and the Four Causes

Aristotle conducted physical and metaphysical studies of being and its properties. Metaphysics is divided into ontology (the study of being as being) and theology (the study of the first cause of universal movement)...
