Only one philosopher has succeeded in building his reputation on silence—Cratylus. It is said that under no circumstance would he say anything, but would merely crook his finger. Nor is it known whether he achieved this unique glory by a persistence that lasted from toothless youth to toothless old age, or whether he merely petered out into withering speechlessness before the follies of man and the grandeur of God. More likely it was something like the latter, for otherwise we would be confronted by the delicate riddle: why was he called a philosopher?

Nevertheless, a tenable explanation is that Cratylus' reputation was arrived at by an experiment. Arranging philosophers on a scale of self .control in speech, one might derive the plausible law: the less one says the more he is of a philosopher. Ergo, say nothing and be declared the worthiest of philosophers. The difficulties in such an extrapolation, however, are very great. It is hard to see what harm just one word can do, and even two or three, or several, if they but fall short of being a sentence. Why absolute silence? Then, again, what harm is there in repeating even a multitude of words, the entire dictionary if you please, plus whatever sounds you can think of, provided you say nothing? And since we have progressed so far with the argument, what harm can there be even in connected speech, grammatical, fluent and mellifluous, provided you still say nothing? Cratylus, apparently, was playing a safe bet with a vengeance. He must have feared being understood (or misunderstood) by accident!
