Key Characteristics of Enlightenment Reason

• Reason is autonomous and self-sufficient.
• Reason has internal limitations.
• Reason is critical: It critiques external factors that undermine its freedom. It performs a sharp analysis of all reality and engages in careful self-criticism. Reason tends to be analytical and tolerant.
• Reason is empirical: It must relate to experience and the empirical world to find a secular rationality.

Enlightenment Reason and Deism

The application of reason to religion led many Enlightenment philosophers to Deism. Deism defends the existence of God as the supreme being, a creator who set the laws of nature but is not concerned with the world, rejecting revelation and religious rituals.

Descartes' Philosophy: The Nature of Ideas and Reality

The Thinking Self: Res Cogitans

I am a thinking thing: a spirit, an understanding, a reason. I possess an absolutely certain truth: the existence of the self as a thinking subject. This truth does not seem to imply the existence of any other reality, because, though I think, perhaps the world does not exist in reality.

The object of thought consists of ideas; thought does not rest directly on things, but on ideas.

Universal Methodical Doubt and Undeniable Reality

Universal methodical doubt has led to an undeniable reality: the existence of a thinking being, i.e., a substance that thinks, a res cogitans, a soul.

Descartes concludes that I can doubt the existence of a body and the world around... Continue reading "Descartes' Philosophy: Doubt, Self, and the Nature of Ideas" »

Plato's Theory of Knowledge

For Plato, the soul belongs to the intelligible world but resides in the material world. This leads to the Theory of Reminiscence, which posits that knowledge is acquired through experience, but we already possess it within us. We must realize that ideas are tools that help the soul remember what it already knows. Knowledge, therefore, comes from memories; to know is to remember. Socrates believed that truth lies within the soul. We should not seek what we do not know, because everything is already inside us.

There are other ways of knowing, such as the dialectic, which is the true knowledge of essences. It involves dialogue and discussions to understand Ideas. Dialectic is above reason, and scientific discourse constitutes... Continue reading "Plato's Theory of Knowledge, Ethics, and Politics" »

Critique of Progress and the Social Contract Idea

In his critique of society, emerging from the idea of progress, Jean-Jacques Rousseau argues that it is impossible to return to the idyllic state of nature. As a solution to the appearance and artificiality to which society leads, he proposed the idea of the Social Contract.

Purpose and Foundations of the Social Contract

This contract represents the basis for establishing a legitimate society, designed to foster justice and happiness among its citizens, thereby excluding inequality. It aims to overcome the shortcomings of previous states (the state of nature and corrupted civil society) by promoting a social model where individuals live in harmony, with their human integrity encompassing both feeling...

Nietzsche on the Human Condition

Continuing with his concept of man, Nietzsche posits that humanity is a fundamentally flawed animal—a disease in the universe. Because humans have not yet consolidated their nature, living involves a serious risk: either overcoming oneself or regressing to primitive animal states. Unlike other species that have produced something superior, humanity often refuses to evolve, clinging to past values instead of creating new meaning.

Despite this negative view, Nietzsche identifies a defining feature that sets humans apart: we are a future-oriented draft. By virtue of radical spontaneity, human beings conceive of ideals, goals, and targets.

Hume and the Science of Human Nature

Hume argued that all sciences related... Continue reading "Nietzsche and Hume: Contrasting Perspectives on Human Nature" »

Machiavelli and the Crisis of Classical Ideal

His position, known as political realism, requires seeing the state as it is and not as it should be. When analyzed from this perspective, the following tenets emerge:

• Men are selfish by nature.
• Human nature is constant and does not change; we observe what men do in the present and what they have done in the past.
• Driven by their own interests, men desire power at any price.
• Politics becomes a science. Its most important finding is that to win and retain political power, one must wisely use terror to control behavior and religion to control consciences.
• Neither religion nor morality legitimizes the state; the state legitimizes itself by force of circumstance.
• The state may seize the property of its subjects

Defining Legal Rules: An Aristotelian Perspective

A primary perspective of a legal rule can be obtained from its definition, provided by the Aristotelian-scholastic mold. The definition represents the expression of the essence of a thing and should include an indication of the general category to which it belongs, in addition to the features that distinguish it from other realities within the same category.

Systematic Frameworks in Legal Institutions

Facing a legal institution through its definition contributes to framing it within a systematic, "regional" context. The definition involves the formation of generic concepts—such as legal relationships or legal business—which were unknown to Roman dogmatics, where legal concepts were often treated...

Classical Athens: Political and Cultural Power (460–late 5th c. BC)

From the year 460 BC until the late 5th century BC, Athens was the most important polis because of its political, social, and cultural power and influence. During this period, Athens fought wars against the Persians (the Greco-Persian Wars) and Sparta (the Peloponnesian War), which highlighted its naval supremacy. The city opted for equality before the law (isonomy), experienced population growth, and its social environment was characterized by religious laxity (more open disclosure of feelings), ideological and political pluralism (greater freedom, education, diversity of opinion, and democratic progress), and ambiguity or moral relativism (absence of singular sacred myths)...

Rousseau's Discourse on Inequality (1754)

The work Man and Society, presented in the Discourse on the Origin of Inequality Among Men (1754), marks a crucial starting point for anthropological thought. It introduces the hypothesis (due to a lack of empirical data) of the "state of nature," the condition in which humans lived before forming organized society.

The State of Nature: True, Good, and Happy

Under this original scenario, man in the state of nature is characterized as true, good, and happy. He is moved primarily by two fundamental feelings:

• Love of Self (Amour de soi): The instinct for self-conservation.
• Compassion for Others: A natural aversion to seeing others suffer (in direct opposition to the views of Hobbes).

In this state, individuals... Continue reading "Rousseau's Philosophy: Inequality, Society, and the State of Nature" »

The Composition of the Real: Aristotle's Hylomorphism

The Hylomorphic theory is the defining feature of Aristotle's philosophy, distinguishing it from Plato's Theory of Ideas while retaining certain similarities and extensions. As Aristotle matured, he partially rejected the Theory of Ideas, recognizing the limitations of Plato's perspective. While he maintained a Platonic mindset, he disagreed with the notion that ideas exist separately from physical objects.

Aristotle argued that every being must contain an explanation of itself within itself. He proposed that reality is a composition of matter and form. Furthermore, he explained that change is a union between matter, form, and essence. While many of his concepts mirror Plato's, the primary...
