Advice For People Who Lie

“People think that a liar gains a victory over his victim. What I’ve learned is that a lie is an act of self-abdication, because one surrenders one’s reality to the person to whom one lies, making that person one’s master, condemning oneself from then on to faking the sort of reality that person’s view requires to be faked…The man who lies to the world, is the world’s slave from then on…There are no white lies, there is only the blackest of destruction, and a white lie is the blackest of all.” 
― Ayn Rand, Atlas Shrugged

“I always say the truth is best even when we find it unpleasant. Any rat in a sewer can lie. It's how rats are. It's what makes them rats. But a human doesn't run and hide in dark places, because he's something more. Lying is the most personal act of cowardice there is.” 
― Nancy Farmer, The House of the Scorpion

“There is beauty in truth, even if it's painful. Those who lie, twist life so that it looks tasty to the lazy, brilliant to the ignorant, and powerful to the weak. But lies only strengthen our defects. They don't teach anything, help anything, fix anything or cure anything. Nor do they develop one's character, one's mind, one's heart or one's soul.” 
― José N. Harris

“Hard truths can be dealt with, triumphed over, but lies will destroy your soul.” 
― Patricia Briggs, Moon Called

“Declare your jihad on thirteen enemies you cannot see -egoism, arrogance, conceit, selfishness, greed, lust, intolerance, anger, lying, cheating, gossiping and slandering. If you can master and destroy them, then you will be ready to fight the enemy you can see.” 
― Al-Ghazali

"Telling lies about others is as harmful as hitting them with an ax, wounding them with a sword, or shooting them with a sharp arrow...You shall not give false testimony against your neighbor."
- God, The Bible
