Understanding Philosophy: Core Concepts and Branches

1.1 What Is Philosophy?

There is no single, exact definition of philosophy, but it can be defined as the result of the activity of researching knowledge. Philosophical activity is characterized by being:

• Rational: Based on logical arguments or empirical observations.
• Systematic: Knowledge must be organized hierarchically, where individual claims derive from general principles, ensuring consistency.
• Critical: No claim is accepted without review. Ancient knowledge is subject to re-evaluation and rejection if proven invalid.

2.1 Philosophy and Science

The first philosopher, Thales of Miletus (630–546 BC), was also an astronomer and mathematician, illustrating that for a long time, there was no distinction between philosophy and science. Both fields share commonalities:

• They are systematic and rational.
• They seek universal truths about the world.
• They share the same objects of study.

During the 16th century, science and philosophy began to diverge as modern science adopted new approaches. However, they remain connected, as philosophy analyzes, evaluates, and questions the methods, reliability, and limits of science.

2.2 Philosophy and Religion

• Coincidences: Both share similar fundamental questions and attempt to provide guidance for life.
• Differences: Philosophy seeks rational knowledge, whereas religion generates knowledge through faith, relying on revealed truths that are not subject to critical demonstration.

1.2 Branches of Philosophy

Philosophy is a broad field that has specialized into several key branches:

• Metaphysics: Literally "beyond physics"; it deals with being and the nature of existence.
• Logic: Investigates the structure, form, and correctness of reasoning expressed through language.
• Epistemology: The theory of knowledge; it examines types of knowledge, scientific limits, and how we know what we know.
• Ethics: The study of moral codes and conduct.
• Aesthetics: The study of art and beauty.

While these are the primary branches, philosophy addresses a vast array of issues and intersects with many other scientific disciplines.
