Like many things in life, truth is hotly debated. Some people think it’s an obstacle to self-improvement:

Lying increases the creative faculties, expands the ego, and lessens the frictions of social contacts.
-Clare Boothe Luce

Some people think it should be used selectively:

People who are brutally honest get more satisfaction out of the brutality than out of the honesty.
-Richard J. Needham

And some see it as a black and white issue:

Those who think it is permissible to tell white lies soon grow color-blind.
-Austin O’Malley

But in any case, everyone has something to say about it…

If you tell a lie, always rehearse it. If it don’t sound good to you, it won’t sound good to anybody.
-Leroy ”Satchel” Paige

It is hard to believe that a man is telling the truth when you know that you would lie if you were in his place.
-Henry Louis Mencken

The hardest tumble a man can make is to fall over his own bluff.
-Ambrose Bierce
