Practical Rationality and Philosophy: Ethics, Morality, and Justice
1. Areas of Practical Rationality and Philosophical Disciplines
Practical rationality encompasses moral action (ethics) and civic/political action (social philosophy). Ethics covers two areas of morality: moral action and civic/political action. Normative ethics reflects on moral and political action and is divided into three branches:
Branches of Ethics
- Descriptive Ethics: A branch of sociology classifying and systematizing moral habits (traditions and customs).
- Normative Ethics: Exposes and reviews
Human Nature, Science, and Free Will
Hypothetico-Deductive Method
The process begins with identifying a problematic situation. A hypothesis, or possible explanation, is then formulated. Using deductive reasoning, the consequences of this hypothesis are explored. These consequences are then tested through observation and experimentation. A sufficient number of carefully selected cases allows for verification or refutation of the hypothesis. If the expected consequences are not met, the hypothesis is rejected, and a new one is formulated.

Ancient Philosophy
The Ionian School and the Pre-Socratics
Philosophy emerged with the Ionians, who sought rational explanations for the world. Their approach emphasized reason and immanent explanations, viewing the universe as an ordered cosmos.
Key figures include the Pre-Socratics, Socrates, Plato, and Aristotle.
The Pre-Socratics explored the fundamental principle of reality (arkhe). They believed in a primary substance from which all things originate and return. Among them were:
- The Milesians

A Critical Look at Tradition
Friedrich Nietzsche’s philosophy stands in stark contrast to much of the Western tradition. While admiring the Presocratics, particularly Heraclitus, for their self-regard and skepticism of the masses, Nietzsche directs sharp criticism towards Socrates, Plato, and the Christian tradition. He views them as proponents of a flawed system of values that has permeated Western culture.

Duty
Kant defines duty as the necessity to act out of respect for the law. Actions can be performed with immediate inclination or disinclination. For example, preserving one’s life is a moral duty and something we are naturally inclined to do. Conversely, a merchant charging fair prices to retain customers acts out of respect for the law but is motivated by the inclination to earn money. In both cases, the action aligns with duty, but the motivation differs.

Determinism
Determinism denies freedom, although it may admit its appearance or accept its coexistence in practice as if it were real, but without truly being as represented.
Foundation in the Natural Sciences
- Physical or Mechanistic Determinism: Although humans can be considered more complex, they would still be determined by the laws of physics or matter.
- Biological or Physiological Determinism: Human behavior is determined by biological or physiological factors. Geneticists argue that human behavior
