[367b]
that there is such a person as a man who is false about calculation and number?
Hippias
Yes.
Socrates
Now who would that man be? Must he not, as you just now agreed, have power to tell falsehoods, if he is to be false? For it was said by you, if you recollect, that he who has not the power to tell falsehoods would never be false.
Hippias
Yes, I recollect, that was said.
Socrates
And just now you were found to have most power to tell falsehoods about calculations, were you not?
Hippias
Yes, that also was said.
