St. Augustine's Defense Against Skepticism

Skepticism, particularly from the New Academy, was defended by denying the possibility of achieving any certainty. "No," says St. Augustine, "even if I were a fool, I would still exist." He argues that the statement "si fallor, sum" (if I err, I am) would always be true, ensuring the certainty of one's existence. However, Augustine asserts that certainty is triple, because man:

• Is (exists)
• Lives
• Understands

The Validity of Knowledge: Inner Experience

Through the certain knowledge that the mind possesses within itself and for itself, in inner experience, St. Augustine establishes the validity of knowledge. Therefore, he contends that one cannot doubt:

• The accuracy of the principles of understanding (e.g.,

Mythos and Logos: Contrasting Philosophical Concepts

The terms Mythos and Logos designate distinct types of discourse. Mythos refers to a particular form of speech that narrates stories of the gods and foundational myths. In contrast, Logos signifies explained and demonstrated speech, rooted in reason.

The word "Logos" itself holds a broad meaning, encompassing concepts such as "account" (telling), "reason," and "calculation." In philosophical discourse, "Logos" is often generalized as a concept contrary to "Mythos." As science or philosophy, Logos represents knowledge founded on rational principles and empirical proof, often through deduction.

In Heraclitus's philosophy, however, "Logos"...

Descartes' Methodical Doubt and the Three Certainties

The Quest for Indubitable Truths

Descartes' attempt to exercise universal doubt aimed not at skepticism, but at establishing a foundation for true knowledge. His methodical doubt sought to identify truths immune to skepticism. Through this process, he established three indubitable certainties.

First Certainty: The Existence of the Thinking Self (Cogito)

Descartes realized that even if he doubted everything else, he could not doubt his own existence as a thinking being. This is encapsulated in his famous phrase "Cogito, ergo sum" ("I think, therefore I am").

Second Certainty: The Existence of God

Descartes reasoned that his own imperfection implied the existence of a perfect being, God. He argued...

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...

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...

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...

Plato's Core Philosophical Concepts

Dialectic: Reaching Truth Through Dialogue

Dialectic is the method to get to the truth through dialogue, as practiced by Socrates and Plato, who was the true master of dialectics. Dialogue allows for the rejection and complement of arguments, thus reaching the truth level by level. This is the true attitude of the philosopher.

The opposite is eristic dialectic, which was very popular in circles of friends who wanted to be right at all costs, aiming to win a thesis whether it was true or false.

Opinion (Doxa): Forms of Knowledge

Opinion, or doxa, is one of the forms of knowledge. It is divided into two main types:

• Conjecture: The idea we have of things when we see their shadows or reflections.
• Beliefs: When we perceive
