If the universe operates by fixed physical laws, what does it mean for us to have free will? That’s what C.S. Lewis considers with an elegant sidewise gleam in an essay titled “Divine Omnipotence” from his altogether fascinating 1940 book The Problem of Pain (public library) — a scintillating examination of the concept of free will in a material universe and why suffering is not only a natural but an essential part of the human experience. Though explored through the lens of the contradictions and impossibilities of belief, the questions Lewis raises touch on elements of philosophy, politics, psychology, cosmology, and ethics — areas that have profound, direct impact on how we live our lives, day to day.
He begins by framing “the problem of pain, in its simplest form” — the paradoxical idea that if we were to believe in a higher power, we would, on the one hand, have to believe that “God” wants all creatures to be happy and, being almighty, can make that wish manifest; on the other hand, we’d have to acknowledge that all creatures are not happy, which renders that god lacking in “either goodness, or power, or both.”
To be sure, Lewis’s own journey of spirituality was a convoluted one — he was raised in a religious family, became an atheist at fifteen, then slowly returned to Christianity under the influence of his friend and Oxford colleague J.R.R. Tolkien. But whatever his religious bent, Lewis possessed the rare gift of being able to examine his own beliefs critically and, in the process, to offer layered, timeless insight on eternal inquiries into spirituality and the material universe that resonate even with those of us who fall on the nonreligious end of the spectrum and side with Carl Sagan on matters of spirituality.
