“Truth is contrary to our nature, not so error, and this for a very simple reason: truth demands that we should recognize ourselves as limited, error flatters us that, in one way or another, we are unlimited.”

“We demand that sex speak the truth [...] and we demand that it tell us our truth, or rather, the deeply buried truth of that truth about ourselves wich we think we possess in our immediate consciousness.”

“The world always makes the assumption that the exposure of an error is identical with the discovery of truth - that the error and truth are simply opposite. They are nothing of the sort. What the world turns to, when it is cured on one error, is usually simply another error, and maybe one worse than the first one.”

“If in other sciences we should arrive at certainty without doubt and truth without error, it behooves us to place the foundations of knowledge in mathematics...”

“It is only that my illusion is more real to me than reality. And so do we often build our world on an error, and cry out that the universe is falling to pieces, if any one but lift a finger to replace the error by truth.”

“Meanwhile, the question is not whether we should 'lose ourselves' - since all do so in one way or another - but where we lose ourselves: in light or in darkness, in good dreams or in nightmares, in truth or in falsehood.”
