Pre-Socratic philosophy

Pre-Socratic philosophy, also called early Greek philosophy, refers to the ancient Greek thinking that came before Socrates. These early thinkers were mostly interested in understanding the world around them, especially how the universe began and what it is made of. They looked for answers in nature and natural laws instead of just blaming the actions of gods. Sadly, most of their original writings have been lost, and we know about them mostly through what later writers said about their ideas.

This philosophy started in the 6th century BC with three thinkers from Miletus: Thales, Anaximander, and Anaximenes. They suggested different basic substances for the world, like water, the unlimited, and air. Other important figures included Heraclitus, known for saying everything is always changing, and Pythagoras, who believed the universe was built on numbers. Later, thinkers like Parmenides argued that nothing changes, while others like Democritus thought the world was made of tiny particles called atoms. These early ideas helped shape many parts of Western thinking and even how we do science today.

Terminology

The term "Pre-Socratic" started in the 19th century. A German philosopher named J.A. Eberhard first used it in the late 18th century. Before this, these thinkers were called physikoi, meaning "physicists," because they studied nature. They were also known as physiologoi, or natural philosophers. This name helped separate them from storytellers and theologians of the time, who often explained things using gods and myths.

The name "Pre-Socratic" was created to show a big change in thinking. Philosophers before Socrates focused on understanding the universe and its order. Socrates and those who came after him were more interested in ethics and politics. However, this term has some problems. Some Pre-Socratic thinkers also cared deeply about how to live a good life. Also, calling them "Pre-Socratic" might make it seem like they were less important or just a step toward later philosophy. In fact, some lived at the same time as Socrates. Because of these issues, some scholars prefer the term "early Greek philosophy" instead. This term helps avoid the problems with the "Pre-Socratic" label and recognizes that some of these thinkers were Socrates' contemporaries.
