Again, A testimony is of small validity if deduced from men out of their own profession; so if _Lactantius_ affirm the Figure of the Earth is plain, or _Austin_ deny there are _Antipodes_; though venerable Fathers of the Church, and ever to be honoured, yet will not their Authorities prove sufficient to ground a belief thereon. Whereas notwithstanding the solid reason or confirmed experience of any man, is very approvable in what profession soever. So _Raymund Sebund_ a Physitian of _Tholouze_, besides his learned Dialogues _De Natura Humana_, hath written a natural Theologie; demonstrating therein the Attributes of God, and attempting the like in most points of Religion. So _Hugo Grotius_ a Civilian, did write an excellent Tract of the verity of Christian Religion. Wherein most rationally delivering themselves, their works will be embraced by most that understand them, and their reasons enforce belief even from prejudicate Readers. Neither indeed have the Authorities of men been ever so awful; but that by some they have been rejected, even in their own professions. Thus _Aristotle_ affirming the birth of the Infant or time of its gestation, extendeth sometimes unto the eleventh Month, but _Hippocrates_, averring that it exceedeth not the tenth: _Adrian_ the Emperour in a solemn process, determined for _Aristotle_; but _Justinian_ many years after, took in with _Hippocrates_ and reversed the Decree of the other. Thus have Councils, not only condemned private men, but the Decrees and Acts of one another. So _Galen_ after all his veneration of _Hippocrates_, in some things hath fallen from him. _Avicen_ in many from _Galen_; and others succeeding from him. And although the singularity of _Paracelsus_ be intolerable, who sparing onely _Hippocrates_, hath reviled not onely the Authors, but almost all the learning that went before him; yet is it not much less injurious unto knowledge obstinately and inconvincibly to side with any one. Which humour unhappily possessing many, they have by prejudice withdrawn themselves into parties, and contemning the soveraignty of truth, seditiously abetted the private divisions of error.
