In... "The Education of Children"... Plutarch gives an anecdote of Theocritus, a sophist, as an example of athuroglossos... he is... "a giant in impudence"... strong not because of his reason, or his rhetorical ability... or his ability to pronounce the truth, but only because he is arrogant. ...His fourth trait is... "putting his confidence in bluster." He is confident in thorubos... the noise made by a strong voice, by a scream, a clamor, or uproar. ...The final characteristic ...his confidence in ..."ignorant outspokenness..." ... it lacks mathesis ...-learning or wisdom.
