Book VIII.
Chapter I.--The Object of Philosophical and Theological Inquiry--The Discovery of Truth. [3703]
But the most ancient of the philosophers were not carried away to disputing and doubting, much less are we, who are attached to the really true philosophy, on whom the Scripture enjoins examination and investigation. For it is the more recent of the Hellenic philosophers who, by empty and futile love of fame, are led into useless babbling in refuting and wrangling. But, on the contrary, the Barbarian philosophy, expelling all contention, said, "Seek, and ye shall find; knock, and it shall be opened unto you; ask, and it shall be given you." [3704]
Accordingly, by investigation, the point proposed for inquiry and answer knocks at the door of truth, according to what appears. And on an opening being made through the obstacle in the process of investigation, there results scientific contemplation. To those who thus knock, according to my view, the subject under investigation is opened.
And to those who thus ask questions, in the Scriptures, there is given from God (that at which they aim) the gift of the God-given knowledge, by way of comprehension, through the true illumination of logical investigation. For it is impossible to find, without having sought; or to have sought, without having examined; or to have examined, without having unfolded and opened up the question by interrogation, to produce distinctness; or again, to have gone through the whole investigation, without thereafter receiving as the prize the knowledge of the point in question.
But it belongs to him who has sought, to find; and to him to seek, who thinks previously that he does not know. Hence drawn by desire to the discovery of what is good, he seeks thoughtfully, without love of strife or glory, asking, answering, and besides considering the statements made. For it is incumbent, in applying ourselves not only to the divine Scriptures, but also to common notions, to institute investigations, the discovery ceasing at some useful end.
For another place and crowd await turbulent people, and forensic sophistries. But it is suitable for him, who is at once a lover and disciple of the truth, to be pacific even in investigations, advancing by scientific demonstration, without love of self, but with love of truth, to comprehensive knowledge.

Chapter II.--The Necessity of Perspicuous Definition.
What better or clearer method, for the commencement of instruction of this nature, can there be than discussion of the term advanced, so distinctly, that all who use the same language may follow it? Is the term for demonstration of such a kind as the word Blityri, which is a mere sound, signifying nothing? But how is it that neither does the philosopher, nor the orator,--no more does the judge,--adduce demonstration as a term that means nothing; nor is any of the contending parties ignorant of the fact, that the meaning does not exist?
Philosophers, in fact, present demonstration as having a substantial existence, one in one way, another in another. Therefore, if one would treat aright of each question, he cannot carry back the discourse to another more generally admitted fundamental principle than what is admitted to be signified by the term by all of the same nation and language.
Then, starting from this point, it is necessary to inquire if the proposition has this signification or not. And next, if it is demonstrated to have, it is necessary to investigate its nature accurately, of what kind it is, and whether it ever passes over the class assigned. And if it suffices not to say, absolutely, only that which one thinks (for one's opponent may equally allege, on the other side, what he likes); then what is stated must be confirmed. If the decision of it be carried back to what is likewise matter of dispute, and the decision of that likewise to another disputed point, it will go on ad infinitum, and will be incapable of demonstration. But if the belief of a point that is not admitted be carried back to one admitted by all, that is to be made the commencement of instruction. Every term, therefore, advanced for discussion is to be converted into an expression that is admitted by those that are parties in the discussion, to form the starting point for instruction, to lead the way to the discovery of the points under investigation. For example, let it be the term "sun" that is in question. Now the Stoics say that it is "an intellectual fire kindled from the waters of the sea." Is not the definition, consequently, obscurer than the term, requiring another demonstration to prove if it be true? It is therefore better to say, in the common and distinct form of speech, "that the brightest of the heavenly bodies is named the sun." For this expression is more credible and clearer, and is likewise admitted by all.
