Theme 2: Science and Other Forms of Human Knowledge

1. Science

One characteristic that distinguishes humans from other living beings is our natural curiosity to wonder about the world in which we live and about our human nature.

To satisfy this curiosity, there have been ways of knowing, understanding, explaining, and interpreting the world and human existence. One way is through philosophy.

Another is through science, which seeks to know reality, find the causes of observed phenomena, establish universally valid concepts, and demonstrate rational arguments. Science provides knowledge about the universe.

1.1 The Scientific Explanation: A Brief History

Science has not always been the same. There have been three main models of scientific paradigms:...

The Unique Method of Reason

The ideal of universal science rests on a unique method valid for all sciences. This method, based on the structure of reason, applies to all individuals and fields of knowledge. To understand this method, we must analyze reason itself. Descartes identifies two fundamental operations of reason: intuition and deduction.

Intuition and the Simple Natures

Intuition is the immediate and effortless grasp of a clear and distinct idea. These intuited objects are "simple natures" or "clear and distinct ideas," the foundation of all knowledge. Key examples are extension and thought, considered innate ideas—potentially present in the mind and revealed through experience.

Deduction and the Composite Natures

Deduction involves...

Nietzsche's Philosophy: The Will to Power and the Dionysian Spirit

For Friedrich Nietzsche, the Will to Power is fundamentally expressed through the Dionysian spirit of humanity. He argues that a crucial balance must be maintained between this instinct and its counterpart (the Apollonian, though not explicitly named here, is implied by the need for balance). Following the ancient Greeks, Nietzsche believed that the profound thinking of the body has been largely overlooked in Western culture. Unlike Western thought, the Greeks never despised the body; they understood it as a mere discipline of feelings and drives, not something to be suppressed or ignored.

Nietzsche's concept of nihilism describes a world...

The Political Philosophy of Machiavelli

Niccolò Machiavelli, the foremost political thinker of the Renaissance, inaugurated modern political science by dealing with the practical affairs of the state. He was a hands-on politician, more interested in intervening in the governance of his state than in abstract theorizing. However, he knew that any goal-oriented action must be guided by theoretical principles.

These principles are outlined in his two most famous works, The Prince and Discourses on Livy, which serve as a guide for rulers. This approach posits that the ultimate goal of politics is to preserve the unity and identity of the community. The general rule is that every city tends toward the degeneration and corruption of its institutions...

Nietzsche's Core Philosophical Concepts

The Problem of "Egyptianism" in Philosophy

The term "Egyptianism" (or a similar concept in Nietzsche's thought) refers to a philosophical tendency that defines a certain quality among Western philosophers and the historical spirit. It is characterized by a failure to grasp genuine historical understanding and a reliance on fixed, rather than useful, sources of moral values. This approach, which reflects a static notion of becoming, ultimately leads philosophy to develop empty concepts.

The Primacy of the Senses

For Nietzsche, the senses provide us with immediate and individual knowledge. This is the basic form of all knowledge, supplied by both our internal and external perceptual systems. The senses, in...

Nietzsche's Critique of Abstract Philosophy

Friedrich Nietzsche criticizes philosophers who deny the reality of change and the dynamism of real life, replacing them with "mummified concepts" – a substance always equal for all eternity. He vehemently rejected the lack of historical sense, arguing that denying change renders history meaningless. Nietzsche also criticized what he termed "Egypticism," which he saw as a taste for the eternal and immutable, akin to Egyptian mummies.

Nietzsche and Heraclitus: Embracing Flux

Nietzsche's perspective resonates with Heraclitus's philosophy, which recognizes that reality is multiple and in continuous change and transformation. For Heraclitus, this change is caused by the constant struggle of opposites (...

Thesis of the eternal return as a sign of vitality. This conception of time is to accept that all world events, all situations and things past, present and future will be repeated forever, an infinite number of times. This thesis can be understood as the expression of the maximum claim of life: life is fleeting, birth, life and death. The will to power, "essence" of life. It is the basic principle of reality from which all beings develop. Characteristics that he is actually being (the will to power) are: irrationality: the reason is just a surface dimension of reality because the world is not rational but chaos, multiplicity, difference, change and death, the reason has the last word, since it is always available to other bodies such as the...

Ethical Criteria of Truth: Evidence and Errors

Evidence is the ultimate criterion of truth, but how do we measure the strength of evidence? Ethics is the most terrible and most glorious aspect of being human. The pattern of life, truth, and values, namely the need to distinguish truth from falsehood to avoid tragedy. Values are at stake as fundamental as peace, freedom, equality, and justice. This is very serious. Some say we cannot agree upon the formulation of ethical principles valid for humanity. Although in some cases there are violent disputes, often there is no disagreement on the fundamentals, but on how to accept or interpret the accepted principles. All these problems that ethics will have to resolve, but should not hide the fact that...

Social Contract Theories

The justification of the state: contractualism: Social Contract: "According to the agreement among the community to enforce laws and make the state appear." They are the citizens who decide to cede power to an authority and legitimacy. These theories are contractualism. Hobbes, Locke and Rousseau. Two forms of state:

• a) State of nature: Describes Life as it would not exist without the state
• b) Welfare state: People are forced to organize on the basis of an agreement or covenant.

Thomas Hobbes

First to use the term social contract. He understood the state of nature and justification of the rule as follows:

1. a) State of Nature. "Homo homini lupus" Man is a wolf to man, without a state is governed by the law of the jungle. The
