“The Strike” conveys Ayn Rand’s philosophy of objectivism:
“My philosophy is basically the concept of the person as a heroic creation, with his own fortune as moral purpose of life, with creative work as his noblest occupation and of reason as his only standard.”
The novel personalities Dagny Taggart, Hank Rearden, John Galt (and a few more) are some of these heroic personalities that improve society through their actions. Against them are pitted the exploiters: politics, mediocrity and oppression.
The so called Objectivism of Ayn Rand is not an original theory, or doctrine (as You may prefer): it is rather a conglomerate of ideas from Nietzsche, on one hand, and the Marginalists, on the other hand, as for example Leon Walras who wrote:
“It is so useful the prayer for the holy man, as it is useful the crime for the criminal man”.
From Nietzsche, Ayn Rand fetched the superman or superwoman (either Dagny Taggart, or Hank Rearden, or John Galt, et al), the hero with supernatural resources, the übermensch sacrificed at the altar of the untermenschen who allegedly are the majority of the people.
We can see in Rand’s heroes a glimpse of the gnostic Pneumatics from the late antiquity, who were automatically entitled to salvation by means of a sort of “biological determinism” — in opposition to the vast majority of the Hylics who were intended to burn in Hell.
Furthermore, Ayn Rand puts a pinch of Darwin and Francis Galton in her theory too, advocating a clear social-Darwinism and a barbaric utilitarian ethics. That’s why Objectivism is politically correct, these days.
