“No Dilettantism in this Mahomet; it is a business of Reprobation and Salvation with him, of Time and Eternity: he is in deadly earnest about it! Dilettantism, hypothesis, speculation, a kind of amateur-search for Truth, toying and coquetting with Truth: this is the sorest sin. The root of all other imaginable sins. It consists in the heart and soul of the man never having been open to Truth; — "living in a vain show." Such a man not only utters and produces falsehoods, but is himself a falsehood. The rational moral principle, spark of the Divinity, is sunk deep in him, in quiet paralysis of life-death.”

As translated in 1,001 Pearls of Wisdom (2006) by David Ross, p. 36
Context: Cling to truth and it turns into falsehood. Understand falsehood and it turns into truth. Truth and falsehood are two sides of the same coin. Neither accept one nor reject the other.

Context: Man consists in Truth. If he exposes Truth, he exposes himself. If he betrays Truth, he betrays himself. We speak not here of lies, but of acting against Conviction.
