Diagnosing the subject of etymology

As for the subject of Principles, the ancients mentioned that it is the four proofs by what they are, or by what they are.

Latecomers discussed both sides. The conclusion of the discussions: that the subject of science should be applicable to the topics of its issues. And both of these two aspects of defining the subject do not have this joke, so you see that the subject of practical principles is doubt, and doubt is not included in the four evidences, and research on requirements such as the study of the corollary between the necessity of a thing and the necessity of its premise is the assignment, and the assignment is not among the corroboration of the four evidences, so all The subject of these researches is not included in the subject of theology according to this definition on both sides. As for the issues of arguments, some of them do not apply to either of the two aspects either, such as the issue of the authority of fame, for fame is not one of the corroboration of the four proofs, and some of them do not apply to the first aspect and the second aspect applies to it, such as the authoritativeness of the appearances of the book, for example. It is necessary to leave this research on the science of origins; Because the evidence and its authoritativeness were taken as a part or a restriction in the subject, so it must be taken for granted in science, and the subject of science is not searched in the same science, even if the subject is the evidence as it is, that would be applicable to this research; Because the phenomena of the book are included in the book. As for the authenticity of a single report, it may be said that it is outside of both aspects. Because the news of a single person is not a book, nor reason, nor consensus, nor Sunnah. Because the Sunnah is the same as the infallible’s saying, action, and approval, not the narration that relates to it, and it may be said: it is outside the first aspect only; Because searching in it is for the evidence of the evidence, but the second aspect applies to it; And that is with the blessing of one of the cares they mention, perhaps the easiest of which is to expand the scope of the Sunnah for the narrative story.

So it turns out: that the science of Usul is based on these two aspects of defining its subject, and many of its researches depart from it. Yes, it may include vocabularies, such as the meaning of the imperative form of the imperative, if it is assumed that the subject of the issue of the signification of the command over the obligation, for example, is the command

The third: that the issues of fundamentals - as we explained in the definition - are the common rules in the jurisprudential analogy, i.e.: that analogy that makes or excuses from reality. Because, with their real existence, they are neither feasible nor excused, but the fundamental rules are the proofs of these titles. Thus it becomes clear: that the subject of the four proofs of Usul is of the utmost importance, those common rules that are established in Usul is, of course, not established by the same bases; This is behind, rather it is proven by a superior reference whose authority is established before knowledge, so it is the source for proving the common rules: either directly or through an intermediary. It is not a foregone conclusion before the science of theology, but rather it is from the research of theology. We have clarified that the predicate does not have to be attributable to the subject in relation to the case to the place, rather it may be the ratio of the effect to the cause, and these evidences are the reason to prove the common rules that he talks about in the science of origins, as it is said in → God Almighty would have been the subject of all sciences that talk about anything in the world; Because God Almighty is the originator of all of them. Accordingly, what is correct is to make the subject of Usul the common elements of deduction as it was mentioned in the three episodes of our Martyr Professor (may his secret be sanctified), not in particular the four or three proofs, for everything in Usul is a search for the common symptoms.
