Foundational Questions and Shared Commitments

The theories of knowledge proposed by Plato and Marx represent two distinct yet interconnected approaches to a fundamental question: What is the reality we need to know? Despite radical differences in their philosophical systems, both thinkers shared a profound commitment to transforming the societies in which they lived through philosophy. Just as Plato was a political thinker aiming to reform ancient Athens, Marx was a political thinker seeking to change the social reality of the 19th and 20th centuries through his philosophical insights. However, the distinctions between these two influential authors are profound.

Ethics of Minimum and Maximum: Foundations of Justice and Happiness

Understanding Minimum Ethics: Civic Foundations

Minimum ethics contains the essential requirements of justice that are absolutely necessary to ensure citizens live in peace and can develop their own idea of happiness. This ethic is also known as civic ethics. It implies that citizens understand and uphold fairness. Its five core principles are:

• Freedom: Understood as moral autonomy—the capacity to make moral decisions for oneself; and political autonomy—the ability to participate in political institutions without coercion.
• Equality: Involves the elimination of domination, ensuring everyone can enjoy a reasonable amount of all goods. Citizens must have minimum social and cultural

Nietzsche's Critique of Western Thought

The text that we have to discuss is an excerpt from Twilight of the Idols, a work in which Nietzsche declares war on the entire tradition of Western thought: philosophers, priests, moralists, and scientists—essentially, all who have defended the morality of slaves and promoted a lifestyle that denies metaphysical life and instincts. In short, he critiques those who have denied the Dionysian.

Philosophy of Reason

As stated in the philosophy of reason, this is a character epistemic text that summarizes Nietzsche's critique of metaphysics and vital morality. Encased in the nineteenth century, Nietzsche's thought is a response to the crisis of Enlightenment reason. The philosophy of the second half of the...

Descartes' Proofs for God's Existence

It is necessary to prove the existence of God without reference to the outside world, only from the analysis of my ideas.

Arguments from the Idea of God

The "cogito ergo sum" gives us the assurance that there are ideas in my mind but does not give us certainty if the objects they represent remain in external reality or not.

The ideas are not different if considered from the point of view of their subjective reality, but when considered from the objective point of view, they are very different from each other.

All these ideas are "caused," and "it is clear that there must be at least as much reality in the cause as in the effect."

The ideas that represent other people or natural things contain nothing so perfect...

2D) Ideas underlined. The proposed text for comment we point out two important expressions: the first is to know, for Descartes knowledge is evidence, in the intuition of clear and distinct from a proposition or opinion beyond doubt. The second term would be doubt, doubt is the first step of the method is a methodical doubt and not skeptical, ie methodical doubt is that their function is related to knowledge, interest in attaining knowledge. It extends to all views acquired without thinking and try to avoid that, without realizing it, incorporate knowledge misjudgments or superfluous. Method refers to the method that made ​​Descartes, which is certain and easy rules, through which observe all that never fail to take as true what is false...

Hume's Empiricism: Experience and the Origin of Ideas

David Hume believes that experience is the source of all knowledge. He asserts that initially, we only know that some of the representations that appear in consciousness are very sharp and intense, while others are faint. The first are called impressions (which may involve feeling or sensing). The latter are called ideas (which involve thinking). Assuming that impressions originate in the outside world is merely an assumption that Hume will investigate. True to the empiricist principle of admitting as true only what is the product of pure experience, Hume sets the fundamental rule of his work:

The Correspondence Principle

There can be no other source for ideas than impressions. Every idea must

Topic 5: Introduction to Philosophical Empiricism

Empiricism emphasizes the role of sensory experience in acquiring knowledge. It denies the existence of innate ideas, proposing that the mind begins as a "blank slate." This perspective challenges traditional metaphysics, which attempts to transcend the boundaries of experience.

1. Epistemological Foundations

1.1. Elements of Knowledge

According to Locke and Hume, an "idea" represents everything we know or perceive. Hume refined Locke's concept of "idea" to encompass sensations and perceptions. He identified two key elements of knowledge:

• Impressions: These are immediate sensations—our direct experience of the world. They are strong, vivid feelings that form the raw data of our senses.
• Ideas:

Ethics 3.LA: Kantian Practical Reason

The Shift to Practical Philosophy

Once the shift in the realm of theoretical philosophy is practiced, the way opens to the Critique of Practical Reason and the fundamental question: "What should I do?" The ethical nature of this issue leads Kant to formulate the necessary form of a moral action, which must respect the principles of freedom and autonomy central to Enlightenment discourse.

The A Priori of Moral Action

It is necessary to investigate the a priori nature of moral action and the form it must take to be considered moral. Consequently, transcendental reason, now practical, is presented as containing the a priori form of moral action. The imperatives of ethics, defined as formal, must be categorical...

Hume's Critique of Rationalist Philosophy

David Hume’s philosophy is deeply connected to René Descartes, primarily through his rigorous critique of the main premises of rationalism.

The Problem of Inductive and Deductive Methods

First, Hume criticizes the methodology of knowledge. He identifies two primary types of methods:

• The Inductive Method: Using particular cases to develop a general law.
• The Deductive Method: Deriving individual cases from a general statement.

Regarding the deductive method, Hume criticizes rationalists for basing their systems on principles that stem from innate ideas to develop knowledge. Hume, like all empiricists, rejects the existence of innate ideas and, therefore, the validity of the deductive method for discovering...

The Nature of Metaphysics

Metaphysics is purely speculative knowledge and is totally separate from experience. Throughout history, its objects of study have been three: God, the soul, and the world. All of them share the fact that they are not objects of experience; that is, they are beyond the scope of empirical knowledge.

Kant and the Scientific Status of Metaphysics

Kant questions whether metaphysics can be considered a science, given that mathematics (specifically arithmetic and geometry) has successfully achieved that status. Throughout history, earlier philosophers attempted to find a method to attain secure knowledge:

• Rationalism: Sought to know metaphysical objects using only reason.
• Empiricism: Criticized rationalist claims, arguing that
