Domination of MetaphysicalIssues and its Challenges

Philosophyof science, among Muslim philosophers, embraces certain priory and crucial rules which the discursive-real sciences must take them as their logical structures. On the basis of the rules, each science should have its own subject and follow in the explanation, the principles and rules of proof expand their domination in their determined boundaries, in their researches should intend the essential properties of subject as well. The later point has not been respected in the metaphysics and violated repeatedly by the philosophers. The subject of metaphysics is being qua being, and all predictions of issues must be essential accidents of the topic while many metaphysical predictions are not such. This methodological error has not been considered by most philosophers. Some others, representing certain solutions, having confessed and acknowledged this error. The most important solutions are two things: the first, the metaphysics has no specific subject. The second, the rules of the philosophy of science are preferable and unnecessary to be followed. The first solution which is the ancient one with a little revise has been accepted in this article as a modern solution. Accordingly, the different branches of philosophy which have their own specific and independent subjects and issues, in virtue of their method and basic issues, can be laid under general topic of philosophy as we can put the sciences under the title of experimental sciences.
