Let’s remember and salute Charles Darwin, the thinker who came to understand the basic mechanism by which we and all other species on earth come to be.

Born on February 12, 1809, Darwin was the grandson of Enlightenment physician, poet, and botanist Erasmus Darwin, who posited his own theory of evolution, as had many others, who observed its effects but had not successfully formulated a theory to explain how it worked. Given that his father was also a physician, it seemed natural that young Charles would take up the family profession. He studied medicine at the University of Edinburgh (my university!) from the age of 16 to 18. Darwin would have attended classes in the original building on South Bridge, now called the Old College, beautifully designed by Robert Adam (it didn’t yet have the dome it has now). While he loved the excellent science education he received there, Darwin decided being a physician was not for him.

His father then sent Darwin to Christ’s College, Cambridge, with the idea that he could be a minister instead. Darwin did well at Christ’s College, but it was his pursuits as a naturalist that really captured his imagination and into which he poured his best efforts. After he completed his Bachelor of Arts degree in 1831, he continued his scientific study of animals and geologic formations. When the opportunity arose to travel to South America on the HMS Beagle later that year, Darwin took it, and spent the next five years gathering specimens and making detailed notes of his observations of the natural world. Among the wealth of valuable scientific information he amassed, Darwin’s observations of the appearance of apparently designed adaptations in living things; fossils of known and unknown animals sometimes found in the most unexpected places (remains of ancient sea life embedded in rocks at high elevation?!?); and the incredible amount of waste and suffering throughout the natural world, from wasps who laid their eggs in living caterpillars so that the growing grubs would devour them slowly from within to the genocide and slavery routinely practiced against the native people there, gave him much to think about.

With his experience broadened, his understanding deepened, and his body strengthened by the rigors of his expeditions, Darwin returned to England a wiser, stronger, more serious man. The first publications of his findings, together with his friendships with influential scientists such as the geologist Charles Lyell, made him famous. Darwin had found his profession. He began to pull together the evidence of his own eyes with the work of other naturalists and scientists to formulate a theory that would explain it all. What would explain a world of living things replete with beauty and waste, some joy and contentment but far more suffering, animals marvelously wrought but more often than not hidden from the human eye either by remoteness, incredibly tiny size, or time through extinction? It was the work of Edinburgh’s own self-made geologist James Hutton, popularized and developed by Lyell, which gave Darwin one key to the mystery. Since it had become clear that the earth was indeed ancient, not young as popular interpretations of the Bible would have it, species had plenty of time to adapt and change to their environment as needed, just as the earth itself had plenty of time to form as it is.

Another key to the mystery was the mass suffering and death Darwin observed. While he mourned it, it was no doubt a comforting realization that it was not designed into the natural world by a divine mind that he was nonetheless bound to worship. Rather, Darwin realized that the living things that could not survive in the environment they found themselves in left those better equipped to do so to reproduce and pass on their adaptations. This realization, this theory of natural selection, Darwin recognized to be explosive as well. It took him about twenty years of careful thought and self-questioning to publish this theory. He knew, for one, that his theory went against people’s natural squeamishness and desire to think of the earth as a friendly home. More than that, Darwin knew perhaps better than anyone what a profound challenge this theory was to orthodox Christianity. But when another naturalist, Alfred Russel Wallace, independently arrived at the same theory, Darwin was galvanized to publish his findings in 1859. His On the Origin of Species went on to become one of the most influential works in the history of thought.

Darwin’s life is a fascinating one in so many more ways outside of the scope of this piece. To learn more about this husband, father, writer, and restless seeker for truth, I recommend the excellent works I’ve linked to below.

Before that, one more thing: I’ve always hated the term ‘Social Darwinism’ because I think it’s terribly misleading. It refers to the idea that societies can be structured so as to direct evolution in some way, for example, by allowing the weakest or least able, as defined by that society, to die off so that the strongest and most able are the most likely to survive and reproduce. But Darwin did not espouse that idea, nor do scientists now understand him to have implied it. For Darwin, as for those who understand the theory of evolution by natural selection as an explanation of a natural process rather than a policy of action, the reason why human beings have become such a successful species is precisely our capacity for empathy and solidarity. It’s the fact that we care about each other as individuals, that we help each other survive and develop our unique capacities that makes us so adaptable, so creative, so able to get by in such a wide variety of environments. Social Darwinism, then, is contrary to Darwin’s own theories about human evolution. Eugenics, ‘survival of the fittest,’ and other such ideas that later thinkers claimed as part of Darwin’s intellectual legacy are not, in fact, his, or ideas that he would endorse given what he actually wrote. The shameful thing about putting Darwin’s name in the term ‘Social Darwinism’ is that it misleads people into thinking that he came up with it, and therefore to think of him as a cruel and heartless thinker, responsible for ideas which have caused much suffering and death. He was nothing of the sort.
