Is Metaphysics a Feasible Philosophical Option?

Before attempting to answer our primary question “is metaphysics a feasible philosophical option?”, I believe that it is necessary to explain and to discuss what the nature of philosophy is, and how it differs from science because my assumption that metaphysics is a feasible philosophical option will get its meaning by showing that metaphysics differs from science as well as philosophy differs from science; furthermore, it would be shown that metaphysics differs from the other options of philosophy. Therefore, in this paper, three concepts will be examined and compared with each other: Philosophy, science, and metaphysics.
