My parents split up when I was 4. My father, a lawyer, wrote the divorce papers himself and included one specific rule: My mother was forbidden to raise my brother and me religiously. She agreed, dissolving Sunday church and Bible study with one swift signature. Mom didn’t mind; she was agnostic and knew we didn’t need religion to be good people. But a disdain for faith wasn’t the only reason he wrote God out of my childhood. There was simply no room in our household for both Jesus Christ and my father’s one true love: Ayn Rand.

You might be familiar with Rand from a high school reading assignment. Perhaps a Tea Partyer acquaintance name-dropped her in a debate on individual rights. Or maybe you’ve heard the film adaptation of her magnum opus “Atlas Shrugged” is due out April 15. In short, she is a Russian-born American novelist who championed her self-taught philosophy of objectivism through her many works of fiction. Conservatives are known to praise her for her support of laissez-faire economics and meritocracy. Liberals tend to criticize her for being too simplistic. I know her more intimately as the woman whose philosophy dictates my father’s every decision.

What is objectivism? If you’d asked me that question as a child, I could have trotted to the foyer of my father’s home and referenced a framed quote by Rand that hung there like a cross. It read: “My philosophy, in essence, is the concept of man as a heroic being, with his own happiness as the moral purpose of his life, with productive achievement as his noblest activity, and reason as his only absolute.” As a little kid I interpreted this to mean: Love yourself. Nowadays, Rand’s bit is best summed up by the rapper Drake, who sang: “Imma do me.”

Dad wasn’t always a Rand zealot. He was raised in a Catholic family and went to church every week. After he and my mother got married in 1982, they shopped around for a church. He was looking for something to live by, but he couldn’t find it in traditional organized religion.

Then he discovered objectivism. I don’t know exactly why he sparked to Rand. He claimed the philosophy appealed to him because it’s based solely on logic. It also conveniently quenched his lawyer’s thirst to always be right. It’s not uncommon for people to seek out belief systems, whether political or spiritual, that make them feel good about how they already live their lives. Ultimately, I suspect Dad was drawn to objectivism because, unlike so many altruistic faiths, it made him feel good about being selfish.
