The Concept of Rational Action

Humans are endowed with reason, which we can use more or less adequately. Rationality is the proper use of reason. It applies to:

• Our beliefs
• Our motives
• Our actions

A rational action is based on good reasons, forming rational beliefs and motives that drive the action for which they are reasons.

Individual Rational Action

This is the action of an individual agent whose reasons for acting are good reasons. Conditions for Individual Rational Action include:

• Awareness of the purposes of consistency and logic, structure, and practical feasibility.
• Priority of objectives over the means.
• Autonomous and universal ends: focusing on one's own welfare.
• Rational beliefs regarding the best ways.
• Rational behavior.

Rational Collective

Descartes' Philosophical Context and Major Works

Animals are capable of carnal love, and we were like trees, sensitive beings. If objects could not love, anything that has movement and feeling could. But as we are men, created in the image of our Creator, who is the eternal truth, eternal and true love, we are able to return there in the triple form of human nature, as the image of God. "I am, I know, I want to be."

René Descartes was born in 1596. He studied at the Jesuit college of La Flèche. After graduation, he decided to learn from the "great book of the world." In 1619, he embarked on a search for truth through the use of reason. His most important works are:

• Rules for the Direction of the Spirit: An unfinished work containing twenty-one

The Will to Power and Eternal Recurrence

The fundamental value exalted by the Will to Power is the exaltation of life. The concept of Eternal Return suggests that all configurations of matter and energy will combine and recur infinitely, meaning every moment will be lived again, exactly as it is now, an infinite number of times. Man is merely a step toward the Übermensch (Superman).

The Three Metamorphoses of the Spirit

The metamorphosis of the spirit involves three crucial stages:

1. The Camel: Symbolizes those who obey and carry heavy loads, such as traditional moral precepts.
2. The Lion: Represents the great conqueror who fights for freedom against the restrictive “Thou Shalt.”
3. The Child: A state of innocence, free from prejudice, ready to affirm

The Dawn of Modern Philosophy

Renaissance Thought, spanning from the fourteenth to the sixteenth century, marked the pivotal transition from medieval to modern philosophy. It was profoundly characterized by a humanistic turn.

From Divine to Human Focus

During this period, God and Christianity ceased to be the sole central points of thought, giving rise to humans as the primary focus. Concurrently, the Church began to lose its exclusive authority in intellectual matters.

Medieval Roots and Renaissance Reactions

The early Middle Ages had limited knowledge of Greek sources, and the period was largely influenced by the Platonism of St. Augustine's extensive work, and to a lesser extent, the Stoics, Skeptics, and Epicureans. However, the late Middle... Continue reading "Renaissance Philosophy: Humanism, Science, and Intellectual Transformation" »

Philosophical Concepts: Ancient to Modern

Natural Concepts and Aristotelian Science

The natural concept, stemming from nominalist philosophy, applies across all fields. Natural science, in this view, distinguishes itself from Aristotelian science. For Aristotle, nature was the principle of movement; a being is natural if it possesses life.

Ockham and Mathematical Thinking

Ockham's mathematical thinking, influenced by Galilean motion, posits that narrative events (symbols) must be measurable and expressible mathematically. He sought the laws of phenomena, believing that true nature reveals itself. Ockham suggested that our mind is limited, while God is unlimited (or perhaps we do not know God, or we are gods). The human mind can only grasp things... Continue reading "Philosophical Foundations: From Ancient Ideas to Modern Science" »

The Moral: Since human freedom allows a person to be both the builder and the building, one is responsible for oneself and one's actions. Therefore, a free action is also a moral action.

The Nature of Moral Action

Human action is characterized by great flexibility for learning. Human behavior is defined by being open and free; this openness to action makes human beings responsible for their individual acts. Before a given action, an individual reflects, makes a decision, and acts accordingly. One must answer for it and be willing to receive recognition or admonishment from oneself and others. This free character of human action is the basis of moral character.

Definition of Moral: A code of rules governing individual and collective... Continue reading "Human Freedom and the Foundations of Moral Action" »

1. Descartes' Methodical Doubt

Overcoming Doubt

Descartes' methodical doubt, unlike radical skepticism, is provisional. The goal is to find a truth that is undeniable.

The Purpose

Descartes' method begins with a diagnosis applied to the era. Humanity is like a sick man who must free himself from his sickness. Descartes decides that the path to truth must undergo a destructive critique of everything we know with certainty.

The Method

Descartes' method is like having faith in critique. It is a seemingly impossible task. He asks skeptical questions, directly attacking the foundations of our knowledge. He applies skepticism to doubt our senses and reason.

1.1 First Argument: Senses and Reason

We cannot trust our senses because they often deceive us (e.... Continue reading "Methodical Doubt in Descartes' Philosophy" »

Empiricism and the Role of Sense Experience

Empiricism is characterized by the value placed on sense experience, minimizing the role of reason regarding reality. The consequence of this approach was that it was not possible to speak of ultimate reality or establish any general principle unless it was feasible for experimental testing. Demonstrating moral truth could only be a feeling or a guide to support value judgments that serve as a criterion in making moral decisions.

Hume: Reason, Sentiment, and Morality

As famously stated, reason is the slave of the passions. Sentiment has to do with pleasure and taste. Virtue is defined as any action that produces a pleasant feeling, and vice is the contrary.

Ethics: Definition and Etymology

Ethics originates from the Greek ethos, referring to character and various aspects of decision-making and responsibility. It is a branch of philosophy that determines the concept of good and evil within specific cultural contexts to improve practical existence. Ethics analyzes the moral life of humans, teaching how to live well and focusing on preferences. It justifies our actions, choices, and behavior, underlying our morality. In essence, ethics and moral philosophy examine human life situations, justify human choices, forge character, and provide living standards.

Morality: Definition and Etymology

The word moral has its roots in the Latin word mos, meaning 'custom' or 'usual'. The moral universe is defined... Continue reading "Ethics and Morality: Principles and Philosophical Traditions" »

Descartes' View of Mind and Body

Descartes' anthropology presents man as a composite of two distinct substances: res cogitans (the thinking substance or soul) and res extensa (the extended substance or body). These substances are considered independent and autonomous.

The Mind-Body Problem

Two important questions arise from this dualism: how do these substances relate, and how do they communicate? Their relationship is undeniable: when the soul gives orders, the body obeys. Descartes' duality of man is a direct result of his metaphysical dualism.

Since the understanding has a clear and distinct idea of thinking substance and a clear and distinct idea of extended substance, it is evident that these are two different, independent substances. This... Continue reading "Descartes: Mind, Body, and Reality" »
