1. A New Cause Area
In October 1819, my grandmother's grandfather's grandfather, Hiram Bingham I, stood with his wife, Sybil, and his friends outside Park Street Church in Boston and bade farewell to family before venturing into the unknown. They would spend the next five months on a cramped ship sailing to a foreign land of strange people, full of "destitution, degradation, and barbarism." They did not know if they would ever return to America.
Unlike others who voyaged out to sea, they were not whalers, nor merchants trying to make a quick profit. Instead, their goal was far more ambitious: to uplift an entire nation out of heathenry to civilization. Or as Hiram wrote, to "most effectually and most extensively promote the Redeemer's cause with the means that are put into our hands".
I first came across Hiram's memoir, A Residence of Twenty-One Years in the Sandwich Islands, on my honeymoon to the Hawaiian Islands last summer. I had vague knowledge of a family connection to the area, and decided to do some research into it. As I started reading, I had a growing sense of deja vu as I recognized my own patterns of thinking in Hiram's words.
Today's Effective Altruists sincerely want to do the most good possible, and often focus on international development as a means of improving lives. However, there is another group who fits that description equally well: 19th-century missionaries.
Hiram and his colleagues believed that Heaven and Hell were not metaphorical, and that doing the most good meant saving the most souls from eternal torment. And what, they asked themselves, was the most effective means towards accomplishing this goal? Spreading the Gospel to those who had never heard it. All of humanity required salvation, and those who lived in foreign lands mattered just as much as those who lived nearby.
As a missionary destination, the Hawaiian Islands (then known as the Sandwich Islands), had several compelling advantages. First, the islands were very neglected, being recently discovered. While not as important as China, Egypt/Palestine, or India, they still held a sizable population. And unlike those places, there was little competition from other missionaries or pre-existing organized religions, making them much more tractable for conversion. The mission to Hawaii would prove notably cost-effective compared to other missions1. Basically all that was needed was a ship, a printing press, and missionaries to teach the Bible.
In other words, if the EA Forum existed in the early 19th century, I could easily imagine a post arguing that bringing the Gospel to the Sandwich Islands is a promising cause area.
So, with the benefit of 200 years of hindsight, what can Effective Altruists and other aspiring do-gooders today learn from the previous wave of people who wanted to save the world?
