The Evolution of Modern Science and Philosophy

The Emergence of Modern Science

Modern science emerged between the 15th and 17th centuries as philosophy began to acquire its own independent status. The first field of research to gain independence was astronomy, triggered by the Copernican Revolution, which proposed the substitution of the geocentric paradigm with a heliocentric one. Subsequently, Kepler challenged the notion of circularity in the movement of the sublunar world.

Galileo and the Experimental Method

Galileo Galilei utilized the telescope to consolidate this new model, famously stating "eppur si muove" (and yet it moves) despite opposition from the Inquisition and the scholastic mentality, which relied on revealed truth. Galileo is...

This document compares the philosophical thought of Plato and the Sophists, highlighting their fundamental disagreements on truth, knowledge, and morality.

Who Were the Sophists?

The Sophists were a group of Greek thinkers who flourished around the second half of the 5th century BCE. They were the first teaching professionals, organizing and collecting complete courses to be taught. Their teachings included:

• Rhetoric
• Logic
• Law
• Morality

Shift in Philosophical Focus

With the Sophists, the focus of philosophy shifted, becoming a concern for humanity rather than nature. This marked a significant anthropological turn in Greek thought.

Physis and Nomos: Nature vs. Convention

The Sophists drew a distinction between physis (nature) and nomos (convention). For...

Formal Science: Deduction and Induction

• Axioms: Principles unprovable within the system.
• Formation and Transformation Rules: Used to extract new statements valid for extending the system.
• Theorems: Statements obtained deductively from axioms.

Natural Science: Hypothetical-Deductive Method

• Protocol Statements: Expressed phenomena of the world likely to be tested empirically.
• Laws: Universal statements about the relation of certain phenomena in a regular and unvarying way.
• Theory: Universal statements from which all the laws of a particular science can be drawn.

Social Sciences: Empirical-Analytical and Hermeneutics

Characterized by less predictability, less generalization, and value neutrality.

Empirical-Rational Origin

Originating in Aristotle, focusing...

Moral Relativism and Ethical Perspectives

Moral relativism posits that concepts of fair and unfair, as well as good and bad, are always relative to specific groups and depend on individual perspectives. Key frameworks include:

• Cultural Relativism: Moral standards depend entirely on different cultures.
• Contextualism: We can only determine if a proposal is right or wrong by considering the specific context of the action.
• Ethnocentrism: The inability to justify the goodness or morality of any human action due to cultural bias.
• Skepticism: Since we cannot find a universal criterion for choosing between options, no choice is objectively better, making it impossible to distinguish between right and injustice.
• Subjectivity: It is impossible to reach a consensus

Three Basic Ideas in Plato:

The Good (Agathon)

The concept of the Good is central to Plato's philosophy. The higher the idea, the better it is. The Good is the ultimate reason for excellence. Plato uses the word Agathon, which doesn't just mean good morals or actions, but also excellence. The highest form of the Good is appropriate or inappropriate. The idea of the Good, when applied to the social world and politics, is identified with the idea of Justice [Justice = OK].

Plato compares the Good with the idea of the Sun. The sun illuminates and gives life to everything. Similarly, the idea of the Good illuminates and gives meaning to all other ideas. The Good provides existence, identity, and perfection to all things knowable. It is the principle...

Plato's Theory of Ideas (or Theory of Forms) stands as the core of his philosophical thought. It emerged from the intellectual ferment of pre-Socratic philosophy, particularly the debate between Heraclitus and Parmenides regarding the nature of change.

Philosophical Foundations

• Heraclitus: Argued that change (logos or reason) was the fundamental principle of reality, famously stating, "You cannot step into the same river twice."
• Parmenides: Contended in his poem that change was an illusion, asserting the impossibility of true change and the eternal, unchanging nature of Being.

Socrates, Plato's mentor, further influenced this theory by opposing the relativism of the Sophists. Socrates asserted that universal ethical and moral concepts (ethical...

Understanding Reason, Knowledge, and Truth

Reason: Practical and Theoretical Rationality: Reason can be understood as the power and the act of explaining something. Theoretical reason is oriented toward the contemplation of the world, that is, to the knowledge of reality. Practical reason, according to Kant, guides action, leading us to a moral idea.

Philosophy and Theoretical Rationality

Philosophy uses theoretical knowledge about reality and truth with the greatest possible rigor. However, unraveling reality requires specifying how we truly know it.

Metaphysical Knowledge

Metaphysical knowledge aims to go beyond scientific explanations. For example, science might discover the human genome, but metaphysics asks if we can reduce ourselves to our...

Philosophical Methods and Approaches

• Maieutic-Dialectical:

  Origin: 5th–4th century B.C. Representatives: Socrates and Plato. Characteristics: The sole form to find the truth is through dialogue. Strength: A foundational and widely used method.

• Empirical-Rational:

  Origin: 4th century B.C. Representative: Aristotle. Characteristics: Knowledge is received through the senses (empirical) and then mediated by explanatory reason (rational). Strength: Normally used in the sciences.

• Rationalist:

  Origin: 17th century. Representative: Descartes. Characteristics: Primacy of reason, clear thinking, and adherence to a reasonable procedure. Effective: Method utilized in mathematics.

Major Branches of Philosophy

Plato's Theory of Knowledge: Epistemology

Characteristics of Platonic Knowledge

Plato's theory of knowledge requires characteristics of objectivity and universal validity. True knowledge, for Plato, must be unchanging and universally applicable.

The Object of Human Knowledge

The object of human knowledge cannot be solely derived from sensitive data. While describing science as a simple table is inaccurate due to its many types, the idea itself is unchangeable and serves as a true object of knowledge.

Degrees of Knowledge

Plato distinguishes between two main degrees of knowledge:

Science (Episteme)

This represents true knowledge, characterized by certainty and understanding of the Forms or Ideas.

• Intuitive Knowledge

  Within the realm of episteme, this

The Noun: Forms and Meanings

Form: Substantive features can receive inflections of gender and number. For example: Dog: Dog-o (masculine gender inflections).

Grammatical Number and Inflections

The Number: This is a grammatical change that provides information as to whether the referent of the noun is one (singular) or more than one (plural). Inflectional markers include -s and -es for plural, or a null marker for singular.

Classification of Nouns by Meaning

• Common or Proper Names: Common names refer to all beings in the same class (e.g., piano, balcony). Names of people are called anthroponyms (e.g., Gabriela, Maria, Mario), and place names are called toponyms (e.g., Madrid, Salamanca).
• Concrete or Abstract Names: Concrete names designate specific
