Classifying nouns according to their meaning is complex, as it involves establishing an order for the realities or beings they designate. However, understanding the traditional classification is essential, as it is the most common:

Common Nouns vs. Proper Nouns

Common nouns designate all members of the same class (e.g., pine, balcony). Proper nouns identify or individualize a being distinct from others of the same class. Proper nouns for people are called anthroponyms (e.g., Gabriela, Eduardo), while those for places are called toponyms (e.g., Madrid, Júcar).

Proper nouns, used to designate individual beings, often accept the plural form. They typically reject the article, except in specific cases:

1. When the proper noun is specified:

Nietzsche on Tragic Art and Life Affirmation

Tragedy vs. Philosophy

For Nietzsche, philosophers often seem to hate life, killing everything they touch. Artists, with their fiction and lies, manage to be faithful to reality, expressing truth better than philosophers, especially tragic artists.

Affirming Life's Pain

In an original and profound way, Nietzsche sees tragic art as the antithesis of the decadent attitude, which is both pessimistic and nihilistic. Nietzsche maintains, against common opinion, that the tragic conception of the world is not pessimistic. Pessimism, for him, is indicative of resignation and regret, a sign of spiritual weakness.

Tragedy, however, is clearly a vigorous affirmation of reality. It teaches that one must always say...

The Problem of Knowledge: Epistemology

Hume is the most important author of the school of empiricism. Empiricism states that all our knowledge comes from experience. Hume denies the existence of innate ideas in reason, prior to experience, since our mind is like a blank page on which nothing is written at birth (tabula rasa).

He distinguishes two elements of knowledge (or "perceptions"): impressions, more vivid mental representations received by the senses (external or internal); and ideas, which are representations or copies of past impressions in the mind, characterized by being less lively. Both impressions and ideas can be simple or complex.

Ideas can be associated or connected according to three basic laws: the law of similarity, the law...

Hume's Epistemology: Relations of Ideas and Matters of Fact

Human knowledge is composed of simple ideas, impressions, and composite materials, but this composition alone does not constitute actual knowledge. Knowing means identifying properties. For example, knowledge is attributed to the "flame" when I perceive the property of "burning." Once I connect these two sets of impressions, I can state that "the flame is burning." David Hume finds that the objects of human reason can be divided into two classes:

1. Relations of Ideas

This term refers to knowledge or truth for which information does not accurately draw on experience. It is sufficient to analyze the words and their meanings. These are necessary truths that cannot be conceived otherwise....

The Socratic Ideal of Self-Examination

Socrates was not a professional philosopher but a simple citizen guided by an unshakeable desire for truth, questioning the values and practices of his time. Socrates gave no definitive answers, nor did he appear to claim he had them. He only knew that the conventional answers of his fellow citizens often lacked true understanding. However, his ideal of life was not exhausted in the negativity of this apparent skepticism. Above all, he wanted individuals to care for their souls and find the truth, believing that truth should illuminate our lives. Socrates was convinced that truth exists, and although hard to find, it is to be found within ourselves. He argued the difficulty lies in our souls being full...

The Cartesian Method: Ideal Mathematical Certainty

Descartes was dissatisfied with his formal training, with the exception of mathematics. He argued that other teachings were misleading and based on false prejudices accumulated over time, lacking inherent value. For Descartes, the only guarantee of truth is the method, which finds its purest expression in mathematics.

The concept of a single, universal method is central to the Cartesian system. Mathematics is not viewed as a specialized field of knowledge, but rather as the foundation for the method applied to all disciplines. If human reason is singular, there must be a single method to attain wisdom.

The Four Rules of the Method

Descartes proposed four requirements for his method, intending to...

Defining Science

Science is a type of knowledge distinct from ordinary knowledge. Ordinary knowledge often focuses on the result of an event, whereas a scientist questions its cause. Science establishes relationships between concepts and formulates laws, asserting that these relationships occur regularly.

Understanding Knowledge

A person knows an event if and only if:

• The subject believes in that event.
• The subject's belief in the event is rationally justified.
• The event is true.

Scientific Knowledge

The scientific community knows a theory if and only if:

• The scientific community believes in this theory.
• The scientific community's belief in that theory is rational and scientifically justified.

These conditions are also necessary; the scientific community...

The Enduring Legacy of Thomas Aquinas

Early Opposition and the Rise of Thomism

Following the death of Thomas Aquinas, his philosophy faced significant opposition, particularly from the Franciscans. They regarded Saint Augustine as the most faithful exponent of the Christian view. This opposition culminated in the condemnation of certain Thomistic doctrines by ecclesiastical authorities in Paris and Oxford in 1277. However, it soon became clear that these fears were unfounded. Following the canonization of Saint Thomas in 1323, Thomism expanded significantly, becoming a dominant intellectual force.

Reason and Faith: Aquinas Versus Augustine

A central theme in medieval philosophy is the ongoing debate between reason and faith. Thomas Aquinas, unlike...

An Approach to Ethics and Morals

The Etymology of Ethics

The word ethics comes from the Greek and has two meanings. The first term comes from the word ethos, meaning custom or habit. Later, this originated from the word ēthos, which means way of life or character. Aristotle believed that the two words are inseparable. Ethics lies in the moral conscience of every human being and serves as an engine, brake, or steering wheel, as appropriate, for the time of action.

Understanding the Scope of Ethics

Ethics is a concept that encompasses a variety of meanings. The word ethos has a much broader sense than that given to the word ethics. Ethics includes the disposition of man in life, character, custom, and morals. We could translate it as "the mode or...

Plato: Athenian Philosopher's Early Life

Plato was born in Athens in 427 BC into a noble family. He received an education in music and gymnastics. A pivotal moment in his life occurred in 407 BC when he met his future mentor, Socrates. Plato studied under Socrates for about eight years until Socrates was convicted of corrupting the youth. Socrates was condemned to drink hemlock and died, refusing to renounce his sentence, accompanied by close friends at his final meal.

Plato was not present during his teacher's final moments, an event reported in the Phaedo. This outrageous injustice likely became the prototype for the philosophical struggle Plato dedicated his life to. Because of this event, the philosopher consistently attacked democracy as...
