BioShock is not only inspired by the theory of Objectivism that Ayn Rand developed and championed in her written works--and famously fictionalized in her novel Atlas Shrugged--but the game's narrative also functions chiefly as a frightening critique of a society shaped in the image of her political and economic beliefs.  Andrew Ryan’s underwater city of Rapture (the name itself used as a double-entendre for both the height of pleasure and the biblical apocalypse) offers the player a visceral demonstration of the pitfalls of what Rand called “rational self-interest” merged with a dystopian alternate history science fiction epic.  

According to Rand:

My philosophy, Objectivism, holds that:

1. Reality exists as an objective absolute —facts are facts, independent of man’s feelings, wishes, hopes or fears.
2. Reason (the faculty which identifies and integrates the material provided by man’s senses) is man’s only means of perceiving reality, his only source of knowledge, his only guide to action, and his basic means of survival.
3. Man—every man—is an end in himself, not the means to the ends of others. He must exist for his own sake, neither sacrificing himself to others nor sacrificing others to himself. The pursuit of his own rational self-interest and of his own happiness is the highest moral purpose of his life.
4. The ideal political-economic system is laissez-faire capitalism. It is a system where men deal with one another, not as victims and executioners, nor as masters and slaves, but as traders, by free, voluntary exchange to mutual benefit. It is a system where no man may obtain any values from others by resorting to physical force, and  no man may initiate the use of physical force against others . The government acts only as a policeman that protects man’s rights; it uses physical force only in retaliation and only against those who initiate its use, such as criminals or foreign invaders. In a system of full capitalism, there should be (but, historically, has not yet been) a complete separation of state and economics, in the same way and for the same reasons as the separation of state and church.

In a nutshell, Rand believed that no human being “owed” any other human being in the world anything, save to be free from the threat of violence from each other, and that every man and woman should be allowed to pursue their own happiness and economic interests without regard to anyone else.   Her theories hold many diverse implications for politics and economics, as well as religion, but the creators of BioShock primarily use the game to explore a single question that Rand takes for granted in her fiction and in her philosophy: “What would a society look like if everyone were really only in it for themselves and owed no allegiance to anyone but themselves?”

The Downside of Hands-Off Capitalism: Rand’s Blindside and Ryan’s All- Too-Human Lust for Power

BioShock succeeds as a serious social critique, rather than just an extremely well-designed video game, largely because of its willingness to tackle the main tenets of Objectivism head-on; not by lengthy diatribes delivered through main characters (even if Andrew Ryan’s famous mid-game speech provides a griping visual reminder that arguments over free will still loom large in our modern cultural consciousness), but by dropping the player into a world where Ayn Rand’s ideas have been allowed to take hold and endure until their logical—and, some might argue, inevitable—conclusion.

The city of Rapture, itself the most damning condemnation of Ayn Rand’s ideas, also functions as the ironic twist of the entire tragedy. By establishing a colony outside the confines of “normal” society and rejecting any principles but his own, Ryan laid the groundwork for his, and Rapture’s, eventual doom. The major flaw in Rand’s theory of Objectivism—and the one which the creators of BioShock seize upon most effectively in their narrative—is that it attempts to deny in ourselves a desire to nurture and empathize with other human beings by placing ourselves at the center of our own interests, to the exclusion of everyone else in our larger society.   The downfall of Rapture was a direct result of Ryan’s attempts to forbid contact with the surface, which was itself a result of Ryan’s effort to install pride as the chief virtue of his city, and deny the corrosive effect of vice and corruption that flourish in the absence of the concept of the collective good.   When the player is dramatically thrust into the heart of this dying city and gradually sees the truth of his, and Rapture’s, situation unfold around him, it’s a potent, immersive reminder that the one trait shared by all dreams of a perfect society is their habit of ignoring the insurmountable flaws in our human nature, often at their own peril.
