New opinions often appear first as jokes and fancies, then as blasphemies and treason, then as questions open to discussion, and finally as established truths.
When a thing is said to be not worth refuting you may be sure that either it is flagrantly stupid - in which case all comment is superfluous - or it is something formidable, the very crux of the problem.
If I have renounced the search of truth, if I have come into the port of some pretending dogmatism, some new church, some Schelling or Cousin, I have died to all use of these new events that are born out of prolific time into multitude of life every hour. I am as bankrupt to whom brilliant opportunities offer in vain. He has just foreclosed his freedom, tied his hands, locked himself up and given the key to another to keep.
But it was ever thus, all through my life: whenever I have diverged from custom and principle and uttered a truth, the rule has been that the hearer hadn't strength of mind enough to believe it.
I cannot often enough say, that a man is only a relative and representative nature. Each is a hint of the truth, but far enough from being that truth, which yet he quite newly and inevitably suggests to us. If I seek it in him, I shall not find it.
To all new truths, or renovation of old truths, it must be as in the ark between the destroyed and the about-to-be renovated world. The raven must be sent out before the dove, and ominous controversy must precede peace and the olive wreath.
