The Saying Of Protagoras Is Like The Views We Have Mentioned; He Said That Man Is The Measure Of All Things, Meaning Simply That That Which Seems To Each Man Assuredly Is.

Hence We Think Of Plants Also As Living, For They Are Observed To Possess In Themselves An Originative Power Through Which They Increase Or Decrease In All Spatial Directions.
