text: Psychology is an academic and applied field involving the study of the mind, brain, and behavior, both human and nonhuman. Psychology also refers to the application of such knowledge to various spheres of human activity, including problems of individuals' daily lives and the treatment of mental illness. \nPsychology differs from sociology, anthropology, economics, and political science in part because it involves studying the mental processes and behavior of individuals (alone or in groups) rather than the behavior of the groups or aggregates themselves. Psychology differs from biology and neuroscience in that it is primarily concerned with the interaction of mental processes and behavior and of the overall processes of a system, and not simply the biological or neural processes themselves, though the subfield of neuropsychology combines the study of the actual neural processes with the study of the mental effects they subjectively produce.\n\n\nPhilosophy is a field of study that includes diverse subfields such as aesthetics, epistemology, ethics, logic, and metaphysics, in which people ask questions such as whether God exists, whether knowledge is possible, and what makes actions right or wrong. The fundamental method of philosophy is the use of reasoning to evaluate arguments concerning these questions. However, the exact scope and methodology of philosophy is not rigid. What counts as philosophy is itself debated, and it varies across philosophical traditions.\n\nThe term philosophy comes from the Greek word "Φιλοσοφία" (philo-sophia), which means "love of wisdom". The term is notoriously difficult to define (see definition of philosophy) because of the diverse range of ideas that have been labeled as a philosophy. The Penguin Dictionary of Philosophy defines it as the study of "the most fundamental and general concepts and principles involved in thought, action, and reality". The Penguin Encyclopedia says that philosophy differs from science in that philosophy's questions cannot be answered empirically, and from religion in that philosophy allows no place for faith or revelation. However, these points are called into question by the Oxford Dictionary of Philosophy, which states: "the late 20th-century... prefers to see philosophical reflection as continuous with the best practice of any field of intellectual enquiry." Indeed, many of the speculations of early philosophers in the field of natural philosophy eventually formed the basis for modern scientific explanations on a variety of subjects.\n\nInformally, a "philosophy" may refer to a general world view or to a specific ethic or belief
