Institutio Oratoria

For there are some advocates so brazen-faced that they bluster and bellow at us, interrupt us in the middle of a sentence

and try to throw everything into confusion. While, then, it would be wrong to pay them the compliment of imitation, we must none the less repel their onslaughts with vigour by crushing their insolence and making frequent appeals to the judges or presiding magistrates to insist on the observance of the proper order of speaking. The debater's task is not one that suits a meek temper or excessive modesty, and we are apt to be misled because that which is really weakness is dignified by the name of honesty.
