and civilly demean'd to strange Persons, they treat strange Opinions and new Inventions at another rate. 'Tis the only Policy accounted to keep a bal∣lance among men, and if any one by a more than ordinary industry and God's blessing on it, hath made at any time a conquest in the Intellectual world, whereby 'tis thought he may get the start of his Neighbours, a rotten Cabal shall make head a∣gainst him, and perhaps, use him with as much se∣verity as a forceable Intruder on another's right; whereas the Secrets of Nature are free to all, and the Victor here enters not by Blood, and Rapine, and Tyrannical oppression, but in a way both innocent in it self, and advantagious to others.
When I reflect on the hard measure the Re∣nowned Dr. Harvey met withal from the pride and peevishness of some conceited Brethren (who esteem nothing Currant but what bears their image and superscription, if not minted in their own brain) on his first demonstration of the Circulation to the World, I cannot but conclude, if I had no other instance for it, That neither Ingenuity, Learning, Modesty, nor any thing that is good and truly valua∣ble can give protection from, though a sufficient antidote against, the poyson of Envy; Envy, that spreading Ring-worm, that Ʋbiquitarian infection, that Canker of what is sound, and Rust of what is bright! to be found almost in all places, in Town and in Country, in the Shop and in the Street, in the Tavern and in the Ale-house; it hovers over all, and pitches where it can, till at last, if it hurt not others, it preys upon it self:
Thou wicked Fiend! that ne'r didst good,
But hast perversly it withstood,
And ever will, till Time shall be
No more, or We
Be rid of Thee.
