Pythagoras probably invented the term philosophy. Typically, the term philosophy refers to a body of knowledge. Philosophical methods involve questioning, critical discussion, logical argument, and organized presentation. Historically, “philosophy” comprises any body of knowledge.
Since the era of Aristotle, natural philosophy implies the combination of astronomy, medicine, and physics. In the modern era, certain teachings that commonly fell under the branch of philosophy became separate academic disciplines. These include psychology, sociology, linguistics, and economics. The concept of philosophy is evolving to include education, mathematics, religion, natural science, and politics.
Philosophy literally means love of wisdom. The history of philosophy can be dated back to the era of pre-Socratic philosophers in the 6th century. These ancient philosophers started by asking questions about some things about life. Majority of those questions were about the truth of creation, the plurality of creatures, and many others. However, they were able to give some explanations about those things through critical thinking, argument, questioning, and other philosophical methods. Also, the huge contributions of Socrates after many years also made philosophy an interesting discipline to the people of that time.
They were able to relate philosophy to medicine, moral values, beauty, art, politics, physics, science, and many others. A lot of these contributions are the basis for most scientific methods that are operational today. Philosophy has to do with a strong desire for knowledge through critical and rational thinking. And as this is being done, knowledge is being formed and the truth is being revealed
