The Thirteenth Century: Context and Scholastic Philosophy

The period between 1225 and 1274 marks the greatest flowering of medieval Europe, with France serving as the primary political and cultural center.

Historical Background of the 13th Century

France enjoyed a stable economy driven by flourishing trade. This stability was underpinned by several factors:

• The stability of the currency and increased circulation of precious metals.
• The consolidation of craft guilds.
• Progress in agriculture, including the adoption of the wheeled plow, the water mill, and crop rotation, which significantly increased field performance.

Socially, this economic boom led to the enrichment of many peasants and bourgeois merchants, while some of the old nobility began to... Continue reading "Medieval Europe in the 13th Century: Scholastic Philosophy and Context" »

Nietzsche's Critique of Metaphysics and Language

Nietzsche's critique of metaphysics involves a static interpretation of being, which he argues strips away the essence of change and becoming. This criticism stems from the German philosopher's view on conceptual knowledge.

Critique of Conceptual Genesis

Platonism and Reification

Nietzsche's first complaint targets a certain Platonism in the genesis and formation of concepts. This has led to the reification and substantification of concepts. Concepts, once created to refer to original experiences or familiarity, have, over time, become substances themselves. They acquire independent life, surpassing the real life they initially attempted to reflect.

Abstraction and Universal Representation

Furthermore,... Continue reading "Nietzsche's View on Concepts and Reality" »

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:

What is Philosophy?

Philosophy is a science that studies theories regarding different aspects of reality. The term originates from philo (love) and sophia (wisdom). Philosophers interpret reality beyond conventional perspectives, maintaining an attitude that encourages critical thinking rather than accepting information at face value.

The Process of Thinking

Thinking involves analyzing reality and constructing abstract concepts. We build mental schemes that allow us to adapt to the world. This requires us to engage with the soul, utilizing words and symbols to interpret reality through ideas.

Forms of Knowledge

• Sensitivity: Knowing through the senses.
• Science: Mathematized knowledge based on rigorous, exacting theories to determine if conclusions

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....

1. The Platonic Conception of Knowledge

Knowing is defined as understanding the universal and becoming familiar with the Ideas. These exist not in the immediate world, but above it. Plato utilizes two primary explanations:

• Reminiscence: A mythical explanation of how knowledge transitions from the sensible world to the world of ideas.
• Dialectic: The process of ascending from lower knowledge toward the Idea of the Good.

Knowledge of Sensible Objects

This produces mere opinion rather than true knowledge:

• Conjecture: Knowledge of images, shadows, and reflections. These are neither discernible, demonstrable, nor intuited.
• Belief (Faith): Knowledge of directly detectable sensible things, such as nature and art. These are imperfect copies of ideas and lack
