Exordia

If you have decided, men of Athens, what it is best to do in the circumstances, it is a mistake to propose debate; for why should you be needlessly bored by listening to what you have yourselves judged to be expedient before hearing it discussed? But if, assuming that you must reach a judgement on the basis of what shall be said, you are exploring and deliberating, it is wrong to stop those who wish to speak, since by so doing you are deprived entirely of whatever practical proposal some speakers have thought up, and you cause other speakers to abandon their own conclusions in favour of what they think you desire to hear.

While to unite in forcing the speaker to express your wishes shows an intention to do wrong, the willingness to deliberate is proved when you listen to his views, scan them and, if any Is good, adopt it. I say this, not as one about to recommend measures opposed to those you are favouring, but as one who knows that, if you refuse to hear the opposition, they will say you have been deceived, while, if you do listen and are not persuaded, they will have been proved on the spot to be offering the worse proposals.
