The First Truth: Cogito

From that universal doubt appears the first truth and certainty. The first base of Cartesian philosophy is: "I think, therefore I am." The cogito is not an argument, but an intuition.

Try to explain rationally the universe, i.e., to explain in terms of man, according to me. It was therefore necessary to start by defining the man, the self, and defining it so that in him were enough elements to build a world system.

The cogito is an act of the subject because I'm the one who thinks.

The ideas represent an inevitable mediation between the thinker and things.

Three Types of Ideas

• Innate: The understanding that has by nature: thought, God.
• Adventitious: Those who come from outside expertise.
• Artificial: Those coming from our imagination.

Metaphysical Theory: The Foundations of Marx's Thought

Marx's thought stems from a critical attitude grounded in the reality of the economic (industrial capitalism), political (liberal), and social systems consolidating during the mid-nineteenth century.

Historical Development and Social Formations

Marx posits that human society has undergone various stages of development throughout history. Each particular society at a given moment is defined by its social-economic formation, which consists of two primary components:

• Economic Structure: The synthesis of the relationship between social productive forces and relations of production.
• Ideological Superstructure: Non-economic elements including politics, morality, philosophy, religion, and art, which

Key Characteristics of Enlightenment Reason

• Reason is autonomous and self-sufficient.
• Reason has internal limitations.
• Reason is critical: It critiques external factors that undermine its freedom. It performs a sharp analysis of all reality and engages in careful self-criticism. Reason tends to be analytical and tolerant.
• Reason is empirical: It must relate to experience and the empirical world to find a secular rationality.

Enlightenment Reason and Deism

The application of reason to religion led many Enlightenment philosophers to Deism. Deism defends the existence of God as the supreme being, a creator who set the laws of nature but is not concerned with the world, rejecting revelation and religious rituals.

The Analytical Transcendental

The Intellectual Conditions of Knowledge

If sensitivity is the function of intuition, the intellect is the function of understanding. This function is performed through concepts and judgments. There are two types of concepts:

• Empirical concepts: Derived from experience.
• Pure concepts (Categories): Derived from the intellect, not from experience.

These categories are necessary conditions for our knowledge of phenomena. The intellect cannot think without utilizing these categories, as they represent the fundamental structures of our thought. While space and time are filled with sense impressions, the categories must be filled with data.

Transcendental Analytic: Understanding and Categories

The Transcendental Analytic study deals with pure concepts, or a priori structures, that organize the understanding. The task of understanding is to synthesize; that is, to reunify the representations obtained through sensitivity. Kant distinguishes pure concepts—those with no empirical content—from empirical concepts, which arise from sensory experience.

The Nature of Categories

Pure concepts are called categories, which are a priori forms of understanding that allow us to think about sensible intuitions. There are two primary conditions regarding categories:

1. Categories are the condition of possibility that makes sensible intuitions thinkable.
2. Categories can only be applied to sensible intuitions;

Descartes' Arguments for God's Existence

The Argument from Perfection

The idea of God is not innate within us, nor does it come from external experience, because neither we nor the world are perfect. Therefore, this perfect idea must originate from a being that is truly perfect. If we, imperfect beings, possess the idea of perfection, this idea must have come from a being more perfect than ourselves. This being is God.

The Ontological Argument

This argument, primarily associated with Anselm of Canterbury, is also known as the ontological argument. Building on the concept of God as a supremely perfect being, Descartes argues that if we conceive of God as possessing all perfections, then existence must be one of those perfections. Therefore, God,...

Nietzsche’s Critique of Traditional Philosophy

From a genealogical perspective, Nietzsche demonstrates that traditional philosophy—specifically Plato and Christianity—has committed the error of rejecting the body and the senses. For Plato, the soul is the substantial component of human beings; it is immortal and eternal. Instead, the body is the accidental component, guilty of vices and errors. The soul must submit to the body and discipline it.

Christianity and the Ascetic Ideal

Christian values are derived from Platonic philosophy. The extreme example is the mystical and ascetic movement, which goes as far as torturing the body so that the soul may reach God. Having denied Christianity and all Western moral foundations, Nietzsche’s thought...

Kantian Concepts: A Priori, Freedom, and Ethics

A Priori and A Posteriori in Kant's Philosophy

The concept of a posteriori is not limited to the issue of knowledge; it is also present in Kant's ethics. In general, a priori is defined as that which does not originate from, or is mediated by, immediate experience. Conversely, a posteriori is that which has an empirical origin, lying in experience and ultimately in perception.

The Concept of Freedom

Theoretical reason cannot prove the existence of freedom. It is only able to grasp the phenomenal world, a world in which everything is subject to the law of causality, and therefore where everything happens by natural necessity.

Etymology of Logic

From the Greek word logos, meaning 'proposition' or 'reason'.

What is Logic?

It is the study of methods and principles for distinguishing good reasoning from bad.

Central Problem of Logic

The central problem of logic is the distinction between right and wrong reasoning.

Premises and Conclusions

Proposition

A proposition is a statement that can be true, false, or indeterminate. It is usually the expression of a judgment.

Structure of a Proposition

• Subject
• Verb (Copula)
• Predicate

Distinction: Questions and Exclamations

Unlike propositions, questions and exclamations do not assert something that can be true or false.

Criteria for Determining Truth

A criterion of truth is a procedure by which we distinguish truth from falsehood. The following criteria are commonly mentioned:

• Authority: A statement is accepted as true because it comes from someone who is granted credit for their knowledge in a subject.
• Tradition: That which has been accepted as true over time and enjoys popular support is taken as true.
• Correspondence between Thought and Reality: What we think will be true if it matches empirical reality. This criterion establishes the adequacy or consistency between what is said and what it is.
• Logical Consistency: This involves checking that there is no contradiction between statements belonging to the same system, and that these statements are necessarily derived
