摘要：Psychology has long been accepted by many scholars as a science. Nevertheless, intensive readings onphilosophy of science and psychology in Indonesia are rarely found. Meanwhile, there are not many professionalpsychologists nor psychology scientists deliver a course on Philosophy of Science in the faculties and studyprograms of psychology. The common argument proposed is that both psychologists and lecturers on psychologyare not well qualified nor confident enough to teach the Philosophy of Science subject, as if the subject "is onlytaught" by philosophers or alumni of philosophy department. This phenomenon depicts that there are twoworlds: the psychology world and the "other world", philosophy. This straight differentiation is certainly bothunnecessary and dangerous as philosophy of science is indeed inherent in any psychological discussions. Thisarticle proposed that philosophy of science is a holistic base for the development of psychology and that therelationship between philosophy of science and psychology is close and tight. Psychologists are expected to takemore part in inquiring assumptions and values in psychology and thus the simplification of psychology as atechnical psychodiagnostic could be avoided.
