I've heard the description "Ayn Rand-ian" too many times now in my life to neglect its meaning.
She scorns the existence of God and altruism. Her philosophy of objectivism (rational selfishness) is polarizing. To this day, she still appeals to certain segments of the population, given that she still sells books, like The Fountainhead. Her position states that there is an objective reality of facts. Perceiving it is through solely reason. Everyone operates in accordance to self-interest. The world is dog-eat-dog, zero-sum, maybe even Hobbesian.
Objectivism is inherently positive, she argues. That respecting one another's freedom in a positive sum game that is a natural result of a society governed by rational and free-thinking men. Laissez faire capitalism is the status quo in a Rand-ian world. Is reason really absolute? Can self-interest as the highest moral code really result in ethical and harmonious actions?
I personally think not. In this age of emotional design, the pinnacle of which can be seen in, for example, advertising, radical empathy is touted in the business world. For me, it is easy to think contrarily to Rand's ideas because I believe that reason is subjective, rather than absolute. She assumes that all self-interested action leads to mutual agreement towards peace, but I think not.
