Mutation

If mutations are harmful, less fit individuals are eliminated by natural selection.

Synthetic Theory of Evolution

This modern theory of evolution, also called Neo-Darwinism, is currently the most accepted theory to explain the evolutionary processes of any population. Modern scientists argue that all biological organization, starting from the molecular level, has gone through an evolutionary process. Natural selection acting on genetic variation remains the way evolutionary changes manifest.

Development of the Theory of Evolution

In the late nineteenth century, the so-called primitive Neo-Darwinism, which is based on the principle of natural selection as the basis of evolution, found in the German biologist A. Weismann one of its main exponents....

Kant's Critique of Pure Reason: Foundations of Knowledge

Immanuel Kant's philosophical inquiry begins with a fundamental question: Is metaphysics possible as a science? (Metaphysics is defined here as that which is beyond physics). Kant meticulously examines what truly constitutes scientific knowledge, analyzing judgments classified into two primary types: analytic and synthetic. Synthetic judgments are further subdivided into synthetic a priori and synthetic a posteriori.

Conditions for Scientific Knowledge

To determine what qualifies as scientific knowledge, Kant subjects each type of judgment to a rigorous screening based on three essential conditions:

• Universality: Applicable everywhere and always.
• Necessity: Must be true; cannot be otherwise.

Karl Popper: Critique of Utopian Political Thought

Karl Popper distinguished between two fundamental societal conceptions:

• Closed Society

  A *mythic-rational conception* characterized by rigid standards, often upheld by tradition and totalitarian power.

• Open Society

  A *rational design* where society prioritizes individual interests, featuring flexible rules that adapt when proven inefficient in solving problems.

The Triple Error of Utopian Conceptions

Popper identified three critical errors in utopian thinking:

• The *epistemological error*: believing we possess thorough knowledge of society.
• The *metaphysical error*: conceiving society as an entity separate and distinct from its constituent individuals.
• The *ethical error*: asserting that the absolute

Hobbes: The State of Nature

The state of nature, according to Hobbes, is the condition of humanity before the establishment of society. In this state, individuals exist in complete freedom and equality, unbound by laws or authority. Consequently, everyone possesses a right to everything, which effectively equates to possessing nothing, as there is no mechanism to enforce or protect individual rights. Driven by selfishness and a lack of restraint, individuals become a threat to one another ("homo homini lupus"), transforming the state of nature into a perpetual state of war and widespread insecurity. This condition impedes progress in all areas, including agriculture, industry, knowledge, and culture.

However, the instinct for self-preservation,...

The World Against Chaos: Opposing Forces and Eternal Return

The world against chaos, the irreducible presence of opposing forces and the eternal return, the predominance of consciousness and rationality over the instincts, and the existence of a punitive God with the intention of weakening desires, feelings, the will to power, pride, ambition, the instinctive, the natural, and the passionate, will be collected by Judeo-Christianity, which sets the Jewish character of sin and resentment. The Jewish priest, due to his inability to satisfy their instincts, reverses the true values: good, noble, powerful, happy, and loved by God become miserable, poor, powerless, inferior, suffering, abstinent, sick, and deformed, while good and beloved by God become...

Descartes' Proof of God and the Nature of Reality

The Existence of God and the Refutation of Doubt

Descartes' proof of God's existence is central to his philosophical system. He argues that there exists an infinite and benevolent God, distinct from the thinking self. This divine being guarantees that clear and distinct ideas, products of proper reasoning, correspond to external realities. This counters the 'evil genius' hypothesis, assuring us that our properly formed thoughts are not systematically deceptive.

Three Fundamental Substances: God, Thought, and Extension

Descartes posits three fundamental substances: God, thought (mind), and extension (matter). God is the ultimate cause of all other realities. Thought and extension are distinct in...

Epistemology in Kant's *Critique of Pure Reason*

In the *Critique of Pure Reason* (CPR), Kant answers the first question raised: What can I know? The question of what we know leads to a more specific question: whether or not a metaphysical science is possible, if one can gain scientific knowledge regarding the world, God, or the soul. In his view, there are two conditions that any intended scientific discourse should satisfy: universality in judgment and the provision of information. This being so, he proposes to operate a sea-change in the epistemological field because, if so far we have assumed that "all our knowledge must be guided by the objects," there is no way of knowing something in them *a priori*. He then expresses the need for objects

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."

The Theory of Knowledge: Epistemological Realism of Aristotle and Aquinas

General Characteristics

1. Two Levels of Knowledge: Distinguishes between sensitive (sensory) and intellectual (understanding) knowledge.
2. Empiricism: Sensitive knowledge captures aspects of reality, while intellectual knowledge grasps aspects beyond sensory experience, such as causality and logical implications. Both levels are integrated within human knowledge.
3. Realism: Knowledge is of reality itself, caused by the objects themselves. It is the faculty by which we become aware of reality.

Sensitive Knowledge

Human knowledge begins with the senses, capturing the sensible qualities of things, forming the base of knowledge content.

1. Sense Organs: The senses, both external (5 senses)

Kant's Practical Reason: Bridging Morality and Metaphysics

Transcendental Idealism, as proposed by Immanuel Kant, rejects the possibility of metaphysical knowledge (concerning God, the soul, freedom, etc.) through intellectual, scientific means. Scientific knowledge, for Kant, is limited to the phenomenal reality. However, Kant identifies one profound experience that can connect us to the metaphysical: the moral experience.

The Postulates of Practical Reason

This connection arises from the so-called Postulates of Practical Reason. These are fundamental propositions that cannot be proven by theoretical reason but must be admitted to understand the "moral factum" (the undeniable fact of morality). These postulates specifically concern:

• The existence
