There is nothing in the world more difficult than candor, and nothing easier than flattery. If there is a hundredth of a fraction of a false note to candor, it immediately produces dissonance, and as a result, exposure. But in flattery, even if everything is false down to the last note, it is still pleasant, and people will listen not without pleasure; with coarse pleasure, perhaps, but pleasure nevertheless.
Fyodor DostoevskyMan has such a predilection for systems and abstract deductions that he is ready to distort the truth intentionally he is ready to deny the evidence of his senses only to justify his logic.
