John Locke: The Method of Consciousness

John Locke proposed a method for understanding consciousness based on three steps:

1. The origin of ideas and how understanding accesses them.
2. Showing the type of knowledge the understanding reaches through these ideas (conocimiento).
3. Researching the nature and basis of what we consider true without having true knowledge (conocimiento).

Locke's Classes of Ideas

Locke categorized ideas into two main groups: Simple and Complex.

Simple Ideas

Simple ideas are real and positive. They are the foundation of feeling and are derived from experience:

• Ideas of Sensation: Ideas coming from external experience, generated by information received through our senses. Locke distinguishes between:
  • Primary Qualities: (e.g., extension,

Marxism: An Introduction

Marxism, developed by Karl Marx (1818-1883), is inextricably linked to Friedrich Engels (1820-1895). Their long collaboration resulted in a significant literary output, with Engels' contribution always acknowledged. Engels' support was crucial, particularly in financing Marx's magnum opus.

Key Collaborations

Their collaborations include the drafting and publication of the Communist Manifesto (1848), a response to the revolutionary events of 1848. This work posits that all societies have historically been defined by class struggle, currently manifested between the proletariat and the bourgeoisie.

Engels also supported Marx in the creation of Das Kapital (1867), a critical analysis of modes of production and a presentation... Continue reading "Marxism: Key Concepts, Theories, and Impact" »

Ethics and Ethical Duty Purposes

The ethics of ends informs you what to do (the purpose). In contrast, the ethics of duty informs you how you should act as you pursue that purpose.

Philosophical Ethics

Aristotle

For Aristotle, happiness is achieved by finding the middle ground on a subject, leading a person to act with caution and virtue.

Epicurus

Epicurus believed happiness is attained by seeking pleasure and avoiding pain. Sometimes, this requires enduring minor suffering now for the sake of greater, long-term pleasure.

Utilitarianism

Only the results matter; the means employed can be good or bad, provided they yield a positive outcome. The core tenet is: "The end justifies the means."

Kantian Ethics

Kant asserted that we must act out of duty, voluntarily... Continue reading "Foundational Concepts in Ethics and Political Law" »

The Transition from the Middle Ages to Modernity

Background: In the thirteenth and fourteenth centuries, knowledge revolved around the relationship between faith and reason, and society was organized according to a theocentric vision of the world. Modernity arises from the confrontation with the Middle Ages.

The Rise of Renaissance Humanism

If medieval life revolved around God, Renaissance humanism stars in a naturalistic turn that promotes anthropocentrism. Man becomes the center of intellectual interest, rediscovering Greco-Roman thinkers through philology. This change in European thought provoked a crisis of European consciousness determined by various social, economic, religious, cultural, artistic, and scientific events.

The Scientific Revolution

Nietzsche's Philosophy: Nihilism and the Death of God

Nietzsche's philosophy takes as its starting point the cultural diagnosis of nihilism. This nihilism is understood as the historical event that Nietzsche called the "death of God."

The Platonic-Christian Tradition and Supersensible Reality

From Socrates to Plato, Western tradition has understood true reality – that which gives existence meaning and intelligibility – to lie in a parallel world. In Plato's philosophy, this is the world of Forms. Christianity, which Nietzsche considered an heir of Platonism, further extended this concept. This world of Forms, or the 'beyond' in tradition, acted as the norm and measure of truth and goodness, serving as the source of all that is true and good...

Descartes' Dualism: The Division of Substance

The reality, according to Descartes, is divided into three classes of things (res) or substances:

• Res Infinita (Infinite Substance): God, the creator of all things, who ultimately serves as the guarantor of our cognitive ability.
• Res Cogitans (Thinking Substance): The ego or soul, representing the innermost nature of man. The ego, as the subject of all intellectual activity, is composed of two faculties: the intellect and the will.
• Res Extensa (Extended Substance): External bodies or material substances.

The Cartesian View of Human Nature

The separation between spiritual substance (Res Cogitans) and extended substance (Res Extensa) profoundly affects the Cartesian view of human beings. The human body,... Continue reading "Descartes' Dualism: Mind, Body, and the Pineal Gland" »

Critique of the Theory of Platonic Reminiscence

Reminiscence in the Meno

After the exposition of Plato's religious-mystical theory of reminiscence, Socrates—the character Plato uses to explain this transitional theory—asks for a demonstration of its "truth," though he does not question its "utility."

Socrates' demonstration is not "brilliant" but "dialectic." We find the famous passage of Meno's slave, who, despite never having received instruction in geometry, is led by Socrates through a trial-and-error process to conclude that the diagonal of a square forms the side of a square double the area of the former. Therefore, that knowledge, not acquired during his life, was found "potentially" in his soul.

The Maieutic Procedure

The "maieutic"... Continue reading "Platonic Reminiscence: Analysis of Meno and Phaedo" »

What Should I Do? Kant's Moral Philosophy

Kant replies: Reason criticizes the practice. Human reason has two faces: reason concerned with the theoretical (what is) and reason dedicated to the practical (what to do). These are two sides of a single reason. The practical face is dedicated to identifying with our will.

The Foundation of Kantian Ethics

To study this aspect, Kant starts from a "factum": the moral law exists in men. We know what is right and what is wrong. Kant wonders if pure reason is enough to know what must be done.

Kant's Critique of Material Morals

Kant’s previous studies on morality led him to criticize what he called "material morals" (MM), stating that they are not well done. Material morals have a double content: they tell... Continue reading "Understanding Kant's Moral Philosophy and the Realm of Ends" »

Two Positions in Modernity: Reason and Senses

1) Empiricism: Knowledge originates and concludes with experience, derived from sensory information. Two types of perceptions exist: impressions and ideas. (Hume)

2) Rationalism: The dominant philosophical tradition of the 17th and 18th centuries, emphasizing confidence in reason as the primary tool for understanding reality. Reason plays a crucial role in discovering innate ideas for true knowledge. (Descartes)

3) Kant: Sensations provide the raw material for knowledge, but human reason organizes it in a universal manner.

The Subjective Construction of Knowledge

1) Sensations: All living beings share sensitivity to external stimuli. While sensitivity varies, sense organs are the structures through which... Continue reading "Epistemology: Reason, Senses, and Knowledge Construction" »

John Locke (1632-1704)

John Locke was a representative of philosophical empiricism, a thinker, an intellectual, and an advocate for a liberal regime. He was a philosopher, politician, physician, and chemist. In his *Essay Concerning Human Understanding* and his *Letter Concerning Toleration*, he defended religious tolerance.

Locke lived through the Middle Ages, a time marked by religious and political intolerance, centralization of power, and a lack of peace and security. Violence, bigotry, and inequality dominated the era. He believed that the solution to the disputes between the Christian sects that arose after the Reformation lay in tolerance. Today, his remarks advocate for a secular state.

His principal works include *Two Treatises of Civil... Continue reading "Key Philosophers and Thinkers: Renaissance to Enlightenment" »
