Philosophy is the study of general and fundamental problems, such as those connected with reality, existence, knowledge, values, reason, mind, and language. Philosophy is distinguished from other ways of addressing such problems by its critical, generally systematic approach and its reliance on rational argument. In more casual speech, by extension, “philosophy” can refer to “the most basic beliefs, concepts, and attitudes of an individual or group”.
The word “philosophy” comes from the Ancient Greek φιλοσοφία (philosophia), which literally means “love of wisdom”. The introduction of the terms “philosopher” and “philosophy” has been ascribed to the Greek thinker Pythagoras. A “philosopher” was understood as a word which contrasted with “sophist“. Traveling sophists or “wise men” were important in Classical Greece, often earning money as teachers, whereas philosophers are “lovers of wisdom” and were therefore not in it primarily for the money.
