David Hume's Theory of Knowledge

Elements of knowledge: The elements of knowledge for Hume are impressions and ideas. These are the contents of consciousness, defined as anything that may be present within the human mind, whether through our senses or the exercise of our thought and reflection.

• Impressions are those perceptions that are presented to the mind with greater force and vivacity.
• Ideas are the result of an operation of the mind on the data previously obtained through impressions. They are images of the impressions that we retain in our minds to remember or think about them.

Cervantes and the Printing of Don Quixote

We recently discovered a request in Cervantes's own hand, addressed to the authorities, in which he authorized the printing of Don Quixote. This discovery is significant for three reasons:

• It provides a new autograph of Cervantes.
• It reveals the title Cervantes himself conceived for his work: The Ingenious Gentleman of La Mancha.
• It offers a key to reading Don Quixote as a celebration of the pleasure of fiction.

Structure of the Quixote

The structure of the work is built upon two pillars: the observation of reality and the symbolic nature of madness, both directly influenced by the literature of the time.

Elements, Qualities, and Temperaments

The work reflects the medical knowledge of the era regarding the... Continue reading "Cervantes and Don Quixote: Literary Analysis and Historical Context" »

Explanation of Marxian Concepts

Marxian anthropology conceives of man as a natural being who possesses a series of capabilities. These allow individuals to meet their needs through the transformation of nature—a process Marx defined as work, which serves as the defining human trait.

The Role of Productive Activity

In the practice of work, humans realize their own being. Consequently, productive activity determines not only the constitution of each individual but also, under the doctrine of historical materialism, the entirety of social reality.

Historical Modes of Production

This human essence is historical because work takes on different forms across various settings, which Marx called modes of production. These comprise all productive forces... Continue reading "Marxian Anthropology: Work, Alienation, and Human Essence" »

Kant's Critique of Traditional Metaphysics

Kant conceives of traditional metaphysics as dogmatic speculation, unsubstantiated and false wisdom, founded only in analytic judgments. This widespread practice seeks truth by considering subjective and objective factors. Kant questions how metaphysical claims are possible. For Kant, the existence of metaphysics as a science (ciencia) depends on certain requirements. All scientific knowledge must expand our understanding and be universal, such that everyone can share in its consensus without doubt or differences. Metaphysical principles and presuppositions do not meet these requirements, as they are founded on analytic judgments that are necessary but do not contribute anything new to knowledge. Metaphysics... Continue reading "Kant's Critique of Metaphysics: Synthetic A Priori Knowledge" »

Kant's Philosophy

Between these two categories, there are two wrecks: Hume's substance and the cause. Categories are given legitimate application to phenomena based on perceptions and lose that legitimacy when we endeavor to apply them to non-empirical or supersensible realities.

Kant again emphasizes the difference between phenomenon and thing in itself.

Kant goes on to show that metaphysics cannot be a science because it lacks the empirical conditions. This is because it looks at God, spirit, and matter (the universe).

The Moral Principles of the Law

Reason is the faculty of reasoning. An argument is a chain of trials. To link the early trials, they are needed. The only way to relate judgments is by linking all trials, each in turn belonging to... Continue reading "Kant's Philosophy: Categories, Metaphysics, and Moral Principles" »

Plato's Ethical Conception of Mathematical Ideas

In The Republic, Plato presents an ethical conception of mathematical ideas. He posits that mathematical ideas exist, and since mathematics is considered a form of rational knowledge, it must have a purpose. This aligns with the existence of ethical ideas, or value-ideas (goodness, beauty, value), which are objects of philosophical knowledge. Plato believed that ideas are interconnected through the idea of property. The idea of good serves as both a cause and a final cause. By introducing a final cause, Plato breaks from the previous mechanistic view and opens the door to a teleological explanation of the world, later developed by Aristotle. This perspective suggests that everything that exists... Continue reading "Plato's Philosophy: Ethics, Politics, and the Ideal State" »

Critique of Pure Reason

Distinguishes two things: the theoretical use and the practical use of reason (metaphysics and ethics). When called pure reason, it refers to reason that is not mixed with anything empirical, which is a priori. Regarding the possibility of metaphysics as a science, Kant stated: "I had to suppress the knowledge to make room for faith."

The conclusion of Kant's metaphysics is that he is agnostic, but he supports the postulates of practical reason: God, Freedom, and Immortality.

Foundations of the Metaphysics of Morals

This work focuses on ethics, but above all, the triple formulation of the categorical imperative:

1. "Act only according to that maxim whereby you can at the same time will that it should become a universal law."

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"... Continue reading "Heraclitus's Logos and Aquinas's Proof of God's Existence" »

The World and Principles of Material Things

When you have demonstrated the existence of God, as an assurance criterion of truth, we have the opportunity to demonstrate the existence of corporeal things, the world. Since God exists, he cannot deceive me into believing that the world exists if it does not; therefore, we conclude that the world exists. Returning to the theory of the objective reality of ideas, this theory posits that the causes of ideas of sensible things are corporeal things, and these corporeal things do exist. God guarantees the truth, but error is not attributable to God; rather, it arises when we deceive ourselves by misinterpreting.

Theory of Substance

Descartes identified three domains of reality: God (or infinite substance)... Continue reading "Descartes: World, Substance, and Mechanism" »
