NATURAL∣PHILOSOPHICAL DISCOURSES.
The INTRODUCTION.
IT hath been both by me and others elswhere at large declared, That there are two things which chiefly draw the minds of men from Truth, and hinder the growth of all Disciplines; viz. A Servile kind of Credulity, and a rash desire of Innovation. How much hurt both of these have done to other Disciplines, let those speak that are skilled in them. That I may speak of Natural Phi∣losophy and Physick which belong to my Profession; it cannot be demed but that much hurt hath been done to both these, especially to Natural Philosophy, whiles some Men little regarding Reason and Experience, have solely adhered to the Authority of other Men; others out of a desire of novelty have endeavored wholly to overthrow the foundations of ancient Discipline. From both these courses I freely profess my self to have been alwaies averse: For neither would I be of the number of those rash Innovators, whether Paracelsians or Chymists, or how ever otherwise called, who endeavor wholly to banish from the Schools the ancient Phi∣losophy, which is come to us chiefly from the Writings of Aristotle: nor yet would I be recko∣ned amongst them who are not ashamed in this Age of ours publickly to profess, that they had rather err with Aristotle and Galen, than speak the Truth with any later Author. The Innowators aforesaid I pass over at present. Touching these latter, I conceive Julius Caesar Scaliger hath well written in Exercit. 306. That those Wits are most unhappy which stifly maintain, That our Ancestors knew al things. I do not verily envy Aristotle those praises wherewith the same Scaliger every where adorns him. Let us grant that Aristotle is a man that hath deserved more than all mortal men besides, of all the parts of Humane Knowledg; that he is the Father and Captain of our Wisdom; that he is the chief Dicta∣tor of Learning, the Emperor of Philosophers; that he is the Eagle of the Philosophical Kingdom of Wisdom, and Literary praise; that he is the Hercules, the Prince, the Tri∣bunal of Truth; that he is the god of Philosophers; and in a word, greater than all praise, and above all Calumny: yet neither he nor any mortal Man can be made the Rule of Truth. Let it be counted a comely and a decent thing to cite the Testimonies of Aristotle as of a prime Philosopher for his Opinion, and to produce as many of them as may be: but if weighty reasons be not added, a mind defirous of the Truth will not be contented with these alone. Their Course therefore is by no means approvable, who taking no care for reasons, contend only with Authorities. Yet this is a fault common enough. For if we look into the Writings of some Men we see nothing brought to prove their Matter, but the Authorities of Hippocrates, Aristotle, and Galen, and oftentimes many interpretations are alleadged touching the sence of some one place, and all those rejected, and at last another substituted, perhaps no better than the former, and so in disputing thereabouts pro and con, so many Pages are taken up, that he must have abundance of leisure that would read them all. And which is a ridiculous thing, the contention is not so much about the mind of the
