Turba Philosophorum
The Sixth Dictum
Lucas saitth:—You speak only about four natures; and each one of you observes something concerning these. Now, I testify unto you that all things which God hath created are from these four natures, and the things which have been created out of them return into them, In these living creatures are generated and die, and all things take place as God hath predestinated. Democritus, the disciple of Lucas, answereth:—Thou hast well spoken, O Lucas, when dealing with the four natures! Then satith AritsLEus:—O Democritus, since thy knowledge was derived from Lucas, it is presumption to speak among those who are well acquainted with thy master!
Lucas answereth:—Albeit Democritus received from me the science of natural things, that knowledge was derived from the philosophers of the Indies and from the Babylonians; I think he surpasses those of his own age in this learning.
The Turba answereth:—When he attains to that age* he will give no small satisfaction, but being in his youth he should keep silence.
