Philosophy can be defined in three ways: etymologically as the love of wisdom, terminologically as different thinkers have defined it, and practically as thinking systematically, rationally, and universally. There are four main branches of philosophy: metaphysics, axiology, epistemology, and logic. Education is defined as a comprehensive process to develop individuals' abilities through social and institutional learning. The philosophy of education views education as a socialization process, a means for cultural development and social integration, and as determining social placement based on academic performance.
