Philosophy is considered the mother of all the other disciplines because of the generality and vastness of its subject matter in contrast to other forms of human inquiry. People talk of philosophy without understanding its role in educational research, particularly its significant contribution to all the other disciplines. It is worth noting that there is nothing in the universe that does not concern or interest philosophy hence philosophical enterprise is essentially the application of reasoning to a wide variety of topics. It is therefore of paramount importance to highlight the important role that philosophy plays in other fields of study in that every discipline raises questions which philosophical investigation can help clarify. Because of the complexity of the world we live in, our efforts to comprehend it are just as diverse. Besides, our different aspirations, interests and activities factor in our endeavor to understand the world and these aspirations and interests find expressions in various fields of study such as history, law, theology, education, economics, political science etc.
Although these fields of study play an important role in our lives generally and in our endeavours to comprehend the world specifically, one cannot divorce them from philosophy. How can this be demonstrated? Given the unrestricted nature of the subject matter of philosophy, one can say that philosophy is an attempt to understand the world, its meaning and values. It examines rationally the fundamental problems affecting man and the world in which he lives. Its field is broad and inclusive. While using the facts and descriptive material presented by other specialized fields of study, philosophy goes beyond description to inquire into the nature, the values and the possibilities of things. Its goal is inclusive, comprehension and wisdom. That notwithstanding, philosophy cannot do without the results of other disciplines. It constantly interrogates and assesses the subject matters of the various fields of inquiry with a view of coming up with a conception of the universe that is coherent and systematic. This paper therefore aims at highlighting the contribution of philosophy to other fields of study such that questions and issues raised in every disciplineare addressed in a fundamental and comprehensive manner.Every domain of human existence confronts us with problems on which philosophical reflection can shed light.
