“There are two kinds of truths: those of reasoning and those of fact. The truths of reasoning are necessary and their opposite is impossible; the truths of fact are contingent and their opposites are possible.”

— Gottfried Leibniz

Il y a aussi deux sortes de vérités, celles de Raisonnement et celle de Fait. Les vérités de Raisonnement sont nécessaires et leur opposé est impossible, et celles de Fait sont contingentes et leur opposé est possible.

“Two sorts of truth: profound truths recognized by the fact that the opposite is also a profound truth, in contrast to trivialities where opposites are obviously absurd.”

Niels Bohr (1885–1962) Danish physicist

As quoted by his son Hans Bohr in "My Father", published in Niels Bohr: His Life and Work (1967), p. 328

As quoted in Max Delbrück, Mind from Matter: An Essay on Evolutionary Epistemology, (1986) p. 167. It is the hallmark of any deep truth that its negation is also a deep truth

“There are most certainly two distinguishable kinds of truths, “truths of reason” (that two plus two equals four) and “truths of fact” (that the sky appears blue). By his resort to his daimon Socrates added the class of “truths of self,” personal truths.”

“Only those afraid of the truth seek to silence debate, intimidate those with whom they disagree, or slander their ideological counterparts. Those who know they are right have no reason to stifle debate because they realize that all opposing arguments will ultimately be overcome by fact.”

“I have been vitally aware of the Law of Opposites, and this awareness has kept me reasonably serene… the drama of life… the play of truth. the quarrel of fools and frauds, male and female, the classic and the romantic, the disciplined and the free… the comic and the tragic contrasting of the opposites in all areas of possibility and on and on and on.”

William Saroyan (1908–1981) American writer

Obituaries (1979)

“The truth is balance, but the opposite of truth, which is unbalance, may not be a lie.”

Susan Sontag (1933–2004) American writer and filmmaker, professor, and activist

Review of Selected Essays by Simone Weil, The New York Review of Books (1 February 1963)
Context: The need for truth is not constant; no more than is the need for repose. An idea which is a distortion may have a greater intellectual thrust than the truth; it may better serve the needs of the spirit, which vary. The truth is balance, but the opposite of truth, which is unbalance, may not be a lie.

“What is truth?” retorted Pilate.
