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.

The Monadology (1714)
“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.”

“There are two kinds of truth: the truth that lights the way and the truth that warms the heart.”
"Great Thought" (19 February 1938), published in The Notebooks of Raymond Chandler (1976)
Context: There are two kinds of truth: the truth that lights the way and the truth that warms the heart. The first of these is science, and the second is art. Neither is independent of the other or more important than the other. Without art, science would be as useless as a pair of high forceps in the hands of a plumber. Without science, art would become a crude mess of folklore and emotional quackery. The truth of art keeps science from becoming inhuman, and the truth of science keeps art from becoming ridiculous.

Unsourced variant: The opposite of a correct statement is a false statement. But the opposite of a profound truth may well be another profound truth.
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
