Here is the defintion of both ~~~~

Psychology (from Greek: ψυχή, psukhē, “spirit, soul”; and λόγος, logos, “knowledge”) is both an academic and applied discipline involving the scientific study of mental processes and behavior. Psychologists study such phenomena as perception, cognition, emotion, personality, behavior, and interpersonal relationships. Psychology also refers to the application of such knowledge to various spheres of human activity, including issues related to daily life—e.g. family, education, and work—and the treatment of mental health problems.

The social science branch of psychology (mainly social psychology) attempts to understand the role human behavior plays in social dynamics (e.g., culture, economics, and politics). Although the natural science branch of psychology differs from biology and neuroscience as a field of study, psychological science has a long tradition of incorporating physiological and neurological processes into its conceptions of mental functioning. Psychology includes many sub-fields of study and application concerned with such areas as human development, sports, health, industry, forensics, and spirituality. As such, psychology is not a unified scientific discipline, with many different perceptions of what the field entails, and many different standards of what constitutes scientific research.

Philosophy is the discipline concerned with questions of how one should live (ethics); what sorts of things exist and what are their essential natures (metaphysics); what counts as genuine knowledge (epistemology); and what are the correct principles of reasoning (logic).[1] [2] The word itself is of Greek origin: φιλοσοφία (philosophía), a compound of φίλος (phílos: friend, or lover) and σοφία (sophía: wisdom).[3][4]

Though no single definition of philosophy is uncontroversial, and the field has historically expanded and changed depending upon what kinds of questions were interesting or relevant in a given era, it is generally agreed that philosophy is a method, rather than a set of claims, propositions, or theories. Its investigations are based upon reason, striving to make no unexamined assumptions and no leaps based on faith or pure analogy. Different philosophers have had varied ideas about the nature of reason, and there is also disagreement about the subject matter of philosophy. Some think that philosophy examines the process of inquiry itself. Others, that there are essentially philosophical propositions which it is the task of philosophy to prove.[5]

Although the word “philosophy” originates in the Western tradition, many figures in the history of other cultures have addressed similar topics in similar ways.[6] The philosophers of the Far East are discussed in Eastern philosophy, while the philosophers of North Africa and the Near East, because of their strong interactions with Europe, are usually considered part of Western Philosophy.
