I'm not a big Ayn Rand fan, but this quote is worth tattooing on my forehead
The smallest minority on earth is the individual. Those who deny individual rights cannot claim to be defenders of minorities. - Ayn Rand
Perhaps the biggest mistake an intellectual can make is to try to parlay his one brilliant insight into a unified theory of existence. Ayn Rand made this mistake with Objectivism. Objectivism was useful for thinking in certain limited realms, but Rand sought to apply Objectivist thinking to every aspect of the human experience, including love. The result is a sterile philosophical landscape, extending out of sight in all directions. Tellingly, Rand was unable to live according to her ideals. This is part of what makes Rand so disagreeable; the almost hysterical denial of subjectivity's inevitable, essential role in our lives. And it makes her not only disagreeable, but wrong.
