Consider Well

"When we lie to ourselves, and believe our own lies, we become unable to recognize truth, either in ourselves or in anyone else, and we end up losing respect for ourselves and for others. When we have no respect for anyone, we can no longer love, and, in order to divert ourselves, having no love in us, we yield to our impulses, indulge in the lowest forms of pleasure, and behave in the end like an animal, in satisfying our vices. And it all comes from lying - lying to others and ourselves."

-Fyodor Dostoyevsky
