Quote by Ayn Rand

"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."

Ayn Rand (writer/philosopher, 1905-1982)
