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" »

History of the Stock Exchange

Over 21 years ago, the concept of the stock exchange emerged. Today, less than 1% of businesses remain listed on the market.

Origins and Early Development

There is no definitive agreement on the origin of stock exchanges. The clearest precursor lies in procurement auctions, where goods were sold publicly, with the price determined by existing demand.

An urban legend traces the birth of this concept to the XV century in Bruges. Operations were reportedly closed in the house of a man named Vander Bouse, whose shield featured three bags (of money).

The commercial center shifted from Bruges to Antwerp. In 1527, Charles V of Germany and I of Spain authorized the creation of a stock exchange there.

Later, between 1608 and... Continue reading "Evolution of Stock Exchanges: From Bruges to Modern Markets" »

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

Scientific and technical texts aim to interpret reality, applying knowledge to explain phenomena without modifying the human environment. The objective of the sender is the transmission of knowledge. Scientific texts typically follow a tripartite structure:

• 1. Presentation: An introduction to the topic. It may consist of a definition of a concept or the contextualization of a fact.
• 2. Development: An orderly and logical exposition of ideas. It follows a linear order governed by causal relationships and enumeration.
• 3. Conclusion: A brief summary of the ideas expressed or the final state of the situation.

Characteristics of Scientific and Technical Language

• Clarity: Uses referential and metalinguistic functions with clear, unambiguous concepts.
• Objectivity:

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 Plot of Life is a Dream

The plot of Life is a Dream is as follows: when Segismundo, Prince of Poland, was born, a horoscope predicted that he would become a cruel and tyrannical king. To avoid this, King Basilio, his father, ordered him imprisoned in a tower. As the play begins, the King hesitates and decides to put his son to a test: he sends for a drugged Segismundo to be brought to the palace and orders that, upon awakening, he be treated as a prince.

The King's Test and the Tower

If his conduct is prudent and virtuous, the King will appoint him his heir; if, on the contrary, he shows himself to be arrogant and violent, he will be locked back in the tower. His noble guardian, Clotaldo, will then persuade him that everything was merely a... Continue reading "Life is a Dream: Segismundo and the Illusion of Reality" »

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...

Rationalism and Empiricism in Modern Philosophy

The emergence of Rationalism in Europe found its strongest representation in France, Germany, and Holland. Rationalism places human reason at the center of knowledge, positing that the mind is filled with innate ideas—concepts that the human mind develops naturally. For instance, rationalists often cite the ideas of infinity and extension as innate.

For rationalists, the foundation of philosophy is to analyze the origin, truth, and limits of human knowledge. Understanding reality is not a straightforward process, as we are not always directly aware of the ideas we hold regarding reality.
