There are different degrees in this aversion to truth; but all may perhaps be said to have it in some degree… — Blaise Pascal

There are different degrees in this aversion to truth; but all may perhaps be said to have it in some degree, because it is inseparable from self-love. It is this false delicacy which makes those who are under the necessity of reproving others choose so many windings and middle courses to avoid offense. They must lessen our faults, appear to excuse them, intersperse praises and evidence of love and esteem. Despite all this, the medicine does not cease to be bitter to self-love. It takes as little as it can, always with disgust, and often with a secret spite against those who administer it. Hence it happens that if any have some interest in being loved by us, they are averse to render us a service which they know to be disagreeable. They treat us as we wish to be treated. We hate the truth, and they hide it from us. We desire flattery, and they flatter us. We like to be deceived, and they deceive us.
