When, however, it is respect for some person that hampers us (which I mentioned as the second condition [*](See § 66.) under which such figures may be used), all the greater caution is required because the sense of shame is a stronger deterrent to all good men than fear. In such cases the judge must be impressed with the fact that we are hiding what we know and keeping back the words which our natural impulse to speak out the truth would cause to burst from our lips. For those against whom we are speaking, together with the judges and our audience, would

For declaimers selected by preference those themes which attracted them by their apparent difficulty, although as a matter of fact they were much easier than many others.
For straightforward eloquence requires the highest gifts to commend itself to the audience, while these circuitous and indirect methods are merely the refuge of weakness, for those who use them are like men who, being unable to escape from their pursuers by speed, do so by doubling, since this method of expression, which is so much affected, is really not far removed from jesting.
