By what he chooses to present and by how he presents it, any author expresses his fundamental, metaphysical values.
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.
