Definition of "Peripatetic"

And though it be True indeed, that some Aristotelians have occasionally written against the Chymical Doctrine he Oppugnes, yet since they have done it according to their Principles, And since our Carneades must as well oppose their Hypothesis as that of the Spagyrist, he was fain to fight his Adverfaries with their own Weapons, Those of the Peripatetick being Improper, if not hurtfull for a Person of his Tenents ; besides that those Aristotelians, (at Least, those he met with,) that have written against the Chymists, seem to have had so little Experimental Knowledge in Chymical Matters, that by their frequent Mistakes and unskilfull way of Oppugning, they have too often expos'd Themselves to the Derision of their Adversaries, for writing so Confidently against what they appear so little to understand.
