Man’s rights can be violated only by the use of physical force. It is only by means of physical force that one man can deprive another of his life, or enslave him, or rob him, or prevent him from pursuing his own goals, or compel him to act against his own rational judgment.

Ayn RandRationalization is a cover-up, a process of providing one's emotions with a false identity, of giving them spurious explanations and justifications - in order to hide one's motives, not just from others, but primarily from oneself. The price of rationalizing is the hampering, the distortion, and, ultimately, the destruction of one's cognitive faculty. Rationalization is a process not of perceiving reality, but of attempting to make reality fit one's emotions.
