"I cannot help persuading myself, that the disputes between contending parties between the defenders of a law and the opposers of it, would stand a much better chance of being adjusted than at present were they but explicitly and constantly referred at once to the principle of UTILITY. The footing on which this principle rests every dispute, is that of matter of fact; that is, future fact the probability of certain future contingencies. Were the debate then conducted under the auspices of this principle, one of two things would happen: either men would come to an agreement concerning that probability, or they would see at length, after due discussion of the real grounds of the dispute, that no agreement was to be hoped for. They would at any rate see clearly and explicitly, the point on which the disagreement turned. The discontented party would then take their resolution to resist or to submit, upon just grounds, according as it should appear to them worth their while according to what should appear to them, the importance of the matter in dispute according to what should appear to them the probability or improbability of success according, in short, as the mischiefs of submission should appear to bear a less, or a greater ratio to the mischiefs of resistance. But the door to reconcilement would be much more open, when they saw that it might be not a mere affair of passion, but a difference of judgment, and that, for any thing they could know to the contrary, a sincere one, that was the ground of quarrel.
...
The question is now manifestly a question of conjecture concerning so many future contingent matters of fact: to solve it, both parties then are naturally directed to support their respective persuasions by the only evidence the nature of the case admits of; the evidence of such past matters of fact as appear to be analogous to those contingent future ones. Now these past facts are almost always numerous: so numerous, that till brought into view for the purpose of the debate, a great proportion of them are what may very fairly have escaped the observation of one of the parties: and it is owing, perhaps, to this and nothing else, that that party is of the persuasion which sets it at variance with the other. Here, then, we have a plain and open road, perhaps, to present reconcilement: at the worst to an intelligible and explicit issue, that is, to such a ground of difference as may, when thoroughly trodden and explored, be found to lead on to reconcilement at the last. Men, let them but once clearly understand one another, will not be long ere they agree. It is the perplexity of ambiguous and sophistical discourse that, while it distracts and eludes the apprehension, stimulates and inflames the passions."
-- (Jeremy Bentham, ch.4 in "A Fragment on Government")
