Freedom and Responsibility

In ancient times, freedom was understood as the ability of humans to act despite the constraints that nature imposed. Humans are free but may require responsibility for their actions. Then, freedom was a divine law. In modern times, freedom is a consequence of accountability. Individual freedom is the foundation of modern political and economic forms, and self-choice human beings have by right.

Ethics and Morality

Morality is related to action, while ethics is the reflection on morality. They have a relationship but are distinct. Morality deals with the set of rules and customs that are accepted as appropriate in one place. Ethics is a critical view of morality, rules, and consequences resulting from human action. It...

René Descartes: A Philosophical Pioneer

Early Life and Education

René Descartes was born on March 31, 1596, in La Haye, Touraine, France. He grew up in a family of minor nobility, the third son of Joachim Descartes and Jeanne Brochard, a lawyer, who died when he was a year old.

He trained at the Jesuit college of La Flèche between 1606 and 1614, where he studied the science and philosophy of his era. He then began his law studies at the University of Poitiers. In 1618, he began serving as a volunteer in the army of Maurice of Nassau, Prince of Orange, and in 1619, for the Duke of Bavaria. However, he soon left his military career to pursue philosophy, his true vocation.

Later Life and Demise

In 1628, Descartes traveled to Holland, where he lived... Continue reading "René Descartes: Life, Philosophy, and Enduring Legacy" »

Hume's Empiricism: Rejecting Innatism

David Hume's philosophy defends the view that all contents of the mind are derived from experience, leading him to reject innatism.

Hume's Theory of Perceptions

Perceptions are the contents of our mind and can be divided into two major classes:

• Impressions

  Impressions are the immediate, vivid data of experience, irreducible and basic. They are strong perceptions received through the senses.

  • Simple Impressions

    These are feelings that come directly to our understanding and cannot be decomposed into parts.

  • Complex Impressions

    Complex impressions are combinations of simple impressions, but derived from simple ideas.

• Ideas

  Ideas are copies of impressions in our minds. They are weaker perceptions.

  • Simple Ideas

    These are ideas

Ethical Theories and Moral Philosophies

Classical Ethical Theories: Socrates

Socrates laid foundational groundwork for Western ethical thought, emphasizing virtue and moral reasoning.

Eudaimonism: Aristotle's Pursuit of Flourishing

Aristotle championed Eudaimonism, a philosophy centered on achieving human flourishing or well-being. He believed that the ultimate goal of human life is to live well and do well, which leads to happiness.

Hedonism: The Pursuit of Pleasure

Derived from the Greek word "hedone" (pleasure), Hedonism posits that the primary goal of life is to obtain pleasure. Epicurus (Hellenistic period) argued that pleasure is a natural criterion for what is good and desirable, advocating for a life of moderate pleasures and tranquility....

The Scientific Revolution: 15th-17th Centuries

Origins and Early Influences

The Scientific Revolution, spanning the 15th to 17th centuries, found its origins in the Middle Ages. It emerged from a critique of the Aristotelian scholastic interpretation, emphasizing the importance of Platonic mathematics.

Key figures laid the groundwork:

• Nicholas of Cusa: Proposed an infinite universe, lacking an absolute center, and supported Neoplatonic ideas.
• Giordano Bruno: Advocated for heliocentrism, further developing Neoplatonic concepts.

Copernicus and the New Cosmic Vision

Nicolaus Copernicus introduced elements that combined an old vision with a new image of the universe. The traditional view considered the universe spherical and adhered to geocentrism. Copernicus,... Continue reading "Foundations of Modern Science: Revolution and Rationalism" »

The World Against Chaos: Opposing Forces and Eternal Return

The world against chaos, the irreducible presence of opposing forces and the eternal return, the predominance of consciousness and rationality over the instincts, and the existence of a punitive God with the intention of weakening desires, feelings, the will to power, pride, ambition, the instinctive, the natural, and the passionate, will be collected by Judeo-Christianity, which sets the Jewish character of sin and resentment. The Jewish priest, due to his inability to satisfy their instincts, reverses the true values: good, noble, powerful, happy, and loved by God become miserable, poor, powerless, inferior, suffering, abstinent, sick, and deformed, while good and beloved by God become...

Groundwork of Fundamental Rights

There are several positions regarding the groundwork of fundamental rights:

First Position: Natural Law as the Foundation

This position explicitly accepts natural law as the foundation for fundamental individual rights. It posits that "Man is a being endowed with reason and free will and has an end in itself. Consequently, the true philosophy of the human person rests on transcendent dignity."

Second Position: Rejection of Natural Law

This position rejects natural law as the basis for fundamental human rights. Instead, it argues that man, within the historical development of society, is covered with varying rights and subjected to the flow of history.

1. The Ius Naturalist Foundation

This perspective defines natural... Continue reading "Fundamental Rights: Natural, Historical, and Ethical Foundations" »

The Soul and Its Essence

Like Plato, Aristotle believed that humans are composed of body and soul. He viewed the soul as the form of the body, making it the essence of humanity. Aristotle distinguished three types of souls:

• Vegetative (plants)
• Sensitive (animals)
• Rational (humans)

Each type of soul imbues the being with its own tendencies. Humans, possessing a rational soul, are distinguished by their capacity for reason.

Human Activity and its Purpose

Aristotle argued that all human activity aims towards a certain end. He differentiated between praxis, actions performed for their own sake, and poiesis, actions performed for the sake of something external. He posited that the ultimate aim of humanity is eudaimonia, often translated as happiness... Continue reading "Aristotle's Philosophy of Soul, Virtues, and Happiness" »

The Sensible and Intelligible Worlds

Plato's theory of knowledge is intrinsically linked to his ontological dualism, which distinguishes between the sensible world and the intelligible world. In the ever-changing sensible world, we can only attain doxa (opinion), a sensory-based knowledge that, at best, coincides with reality. This inadequate knowledge, based on perception, satisfies only the ignorant.

The intelligible world, characterized by eternity, immutability, and permanence, offers episteme (true knowledge), providing wisdom and understanding of causes. This is the knowledge sought by the sage, who can demonstrate truth to others.

Levels of Knowledge: The Divided Line

In the Republic's allegory of the divided line, Plato further elaborates... Continue reading "Plato's Theory of Knowledge and its Ontological Foundations" »

Alma (Soul)

A finite spiritual substance. It is simple because it is not composed of parts and therefore immortal. It is an independent substance from the body and does not require it to exist. It is the principle of consciousness, that is, what makes us aware.

Certainty

An act of perfect understanding that fully recognizes the clarity, distinction, and conviction of truth. It is the security of possessing the truth. It is based on evidence. It refers to the evidence that something is true, as false certainty can exist: being sure of something that is actually wrong.

Clarity and Distinction

These belong to the first rule of the Cartesian method and are key features of evidence. Claro is what is transparent, clear, and visible to reason. Distinto... Continue reading "Cartesian Philosophy: Key Concepts and Definitions" »
