Fundamentals of Argumentative Texts

An argumentative text advocates an idea by providing a set of reasons for it. It seeks to alter the opinion of a recipient, reinforce their existing beliefs, or achieve their adherence to a specific viewpoint. Success is based on the effectiveness of the arguments presented.

Argumentation vs. Persuasion

Argumentation and persuasion base their explanations and reasoning on proof, logic, and rational argument. Argumentation tries to be objective, while persuasion leans toward the subjective. When the text is developed for use in the media, the two are often intertwined.

Organization and Content Structure

General Organization of Argumentation

Argumentative texts are generally organized into three structural parts:...

John Locke's Liberal Social Contract

Locke's political thought is of great importance, as it forms the theoretical basis of the modern liberal state. His key tenets include:

1. According to Locke, man is a social being by nature, possessing certain natural rights.
2. In the state of nature, the most important rights are security and property. However, this coexistence may lead to excessive 'interest,' causing insecurity.
3. Therefore, to address these interests, Locke advocates for building a state that guarantees the life and property of its members. The state's mission is to serve its members, ensuring their welfare and protecting their property, which it may not dispose of.
4. To prevent any abuse of power or interests, power is split between the legislature

Descartes' Skepticism Towards Scholasticism

The starting point of René Descartes' philosophy is the disillusionment caused by traditional scholastic knowledge. He considered this knowledge entirely insecure, where everything was doubtful, and all issues presented a variety of conflicting opinions. This skepticism extended to philosophy in general and, consequently, to all sciences dependent on it, as none seemed to possess sufficiently secure foundations.

The Tree of Knowledge and the Quest for Certainty

Descartes envisioned knowledge as a unified "great tree," with metaphysics as its roots, physics as its trunk, and various sciences like medicine, mechanics, and morals as its branches. His fundamental objective was therefore to demolish the...

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...

John Locke (1632–1704): Father of Liberalism

John Locke is considered the father of political liberalism. His most important work is Two Treatises of Government.

The Social Contract and Consent of the Governed

The main idea of Locke's philosophy is that the power of rulers is based on the consent of the governed.

The State of Nature (Locke)

For Locke, civil government arises through a social contract. His State of Nature is characterized by:

• Complete Equality: No one is above anyone else.
• Perfect Freedom: Individuals can do whatever they want with themselves and their properties.
• Natural Law Limit: This freedom has a limit—the obligation not to harm others.

Men leave the State of Nature because not all individuals adhere to natural law; some violate...

Scientific Explanations

A scientific explanation provides an answer to the question of why a particular event has occurred. The philosopher Ernest Nagel classified scientific explanations into four distinct types:

• Deductive Explanation: Typical of natural and formal sciences.
• Probabilistic Explanation: Common in human sciences and medicine.
• Teleological Explanation: Clarifies historical events or human behavior.
• Genetic Explanation: Used in history and the natural sciences.

The Scientific Method

A method is a stable process consisting of specific rules to achieve a goal; the term literally means path. Key methods include:

• Deductive Method: Deriving specific conclusions from general principles. Only feasible in formal sciences.
• Inductive Method: Reasoning

Aristotle's Philosophy: Virtue, Ethics, and Happiness

Aristotle addresses the concept of virtue in his ethics as a means to achieve the highest good: happiness. He distinguishes between intellectual virtues, attained through the practice of contemplative life, and ethical virtues, cultivated through the habit of acting and aligning our behavior with the golden mean between two extremes—one of excess and one of deficiency.

Aristotle's View on Happiness and Perfection

Aristotle posits that virtue guarantees the enjoyment of happiness because every being achieves perfection within its kind. Happiness is derived from engaging in activities specific to one's nature. Given that human nature is defined by its specific form, the rational soul, a life...

Notion of Freedom

What defines freedom is the power to direct and dominate one's actions, the ability to set a goal and head toward it. It is more about self-control than governing others' actions. In the free act, two higher faculties of the soul come into play: intelligence and will. The will chooses what has previously been known by intelligence. To do so, before deliberately choosing, the mind considers various possibilities, with their different advantages and disadvantages. The decision is the result of that mental consideration of possibilities. I decide when I choose one of the possibilities discussed. It is not the possibility that forces me to take it; rather, I am the one who makes it happen.

To be human is to be free. There is physical...

Plato's Philosophical Connection to Pythagorean Thought

The Pythagorean school, due to its significant popularity and the encounters Plato had with its members, exerted various influences on his philosophy.

Shared Philosophical Foundations

Mathematics as a Path to Knowledge

Plato, in some ways, agreed with the importance attributed by the Pythagorean school to numbers, famously encapsulated in the maxim: "Numbers are the essence of all things." He also adopted their division between body and soul.

Plato believed that mathematics serves as a crucial tool for attaining knowledge of the Forms (or Ideas). While the Forms represent the true essence and occupy the highest ontological plane, mathematics, though a notch lower (similar to the Divided Line'...

Ancient Wisdom

1^st Premise: All men tend by nature to know. 2^nd Premise: Knowledge through the senses gives wisdom. Thesis Conclusion: Human wisdom is to know the first causes and principles of things. (Fifteenth century BC) Aristotle tells us the ultimate goal of wisdom: knowledge of first principles.

Introduction to Early Greek Thought

The birthplace of Greek philosophy was the coast of Asia Minor, and the first philosophers were Ionians. Philosophy is both an individual activity and a product of society, reflected in the conception of law as the order of the cosmos. Philosophy arises from a shift in thinking: the abandonment of mythical thought and the emergence of rational thought. Mythical elements are found not only in the first philosophers...
