Key Concepts in Western Philosophy: From Pre-Socratics to Modernity

Key Concepts in Western Philosophy

Characteristics of Philosophical Thinking

The work of the philosopher is to reflect on reality, whatever it may be, rediscovering its deeper meanings. It involves overcoming naivete and relying on rigorous and comprehensive thought.

Pre-Socratic Schools

Three prominent pre-Socratic schools are:

  • Thales of Miletus
  • Heraclitus
  • Parmenides

Thales of Miletus considered water to be the essential element of all matter, believing it to be the first element of things, the beginning of everything.

The Importance of Philosophy for Humanity

Philosophy is important because it addresses the insatiable curiosity of human beings, prompting us to question and seek understanding.

Pre-Socratic vs. Socratic Philosophy

Pre-Socratic philosophy primarily focused on explaining the origin of the world and the causes of transformations in nature. Socratic philosophy, in contrast, began to investigate human issues, such as ethics, politics, and techniques.

Plato’s Philosophy

Plato believed that the process of knowledge develops through a gradual transition from the world of shadows and appearances to the world of ideas and essences. He proposed a method of thought and language called dialectics.

Aristotle’s Philosophy

Aristotle posited that there is only one world, which contains both essences and appearances. He is considered the creator of logic, which he viewed as a tool for acquiring knowledge.

The Basis of Medieval Christian Philosophy

Medieval philosophy was characterized by the dominance of the Roman Church in Europe and beyond. During this period, Christian philosophy, or rather theology, emerged. Its fundamental basis was the distinction between the infinite God and finite man and the world, between body (matter) and soul (spirit). Key themes included divine perfection and the paths that lead to God. Notable figures include St. Augustine and Thomas Aquinas.
