Philosophy (English: philosophy, from Greek: φ ι λ ο σ ο φ? α) etymologically means "love and wisdom". In academic circles, there is no universally accepted definition of the word philosophy, and it is impossible to foresee the possibility of reaching an agreed definition. As far as western academic history is concerned, philosophy is the study of some problems and the concepts involved.

Philosophy is the study of universal and basic problems, which are mostly related to reality, existence, knowledge, value, reason, mind and language.

In the East, the word philosophy is usually used to describe a person's outlook on life (such as a person's "philosophy of life") and basic principles (such as values, thoughts and behaviors). Academic philosophy is to question and reflect on the rational basis of these basic principles and try to reconstruct them rationally.

In daily language, the word "philosophy" can be extended to the most basic beliefs, concepts and attitudes of individuals or groups, and the word philosophy can refer to a purpose, proposition or thought.
