There may be a question came to your mind that why PhD is expanded as a doctor of philosophy if it is awarded in almost every field. In the context of academic degrees, philosophy doesn't merely refer to the field of philosophy or the holder of PhD does not necessarily study philosophy, rather it refers to its original Greek meaning which is "love of wisdom".
