There is nothing more necessary than truth, and in comparison with it everything else has only secondary value.
This absolute will to truth: what is it? Is it the will to not allow ourselves to be deceived? Is it the will not to deceive? One does not want to be deceived, under the supposition that it is injurious, dangerous, or fatal to be deceived. ... Do not allow yourselves to be deceived: Great Minds are Skeptical.

What if God were not exactly truth, and if this could be proved? And if he were instead the vanity, the desire for power, the ambitions, the fear, and the enraptured and terrified folly of mankind?
(Friedrich Nietzsche, 1890)
