The struggle alone pleases us, not the victory. We love to see animals fighting, not the victor infuriated over the vanquished. We would only see the victorious end; and, as soon as it comes, we are satiated. It is the same in play, and the same in the search for truth. In disputes we like to see the clash of opinions, but not at all to contemplate truth when found. To observe it with pleasure, we have to see it emerge out of strife. So in the passions, there is pleasure in seeing the collision of two contraries; but when one acquires the mastery, it becomes only brutality. We never seek things for themselves, but for the search. Likewise in plays, scenes which do not rouse the emotion of fear are worthless, so are extreme and hopeless misery, brutal lust, and extreme cruelty.
From Pascal’s Pensées.
