Scottish novelist David Lindsay (1876-1945) was born to a middle-class Calvinist family, forced by poverty to work as an insurance clerk instead of attending university, and at the age of 40 took up the cause and worked his way to Corporal of the Royal Army Pay Corps in World War I. After the war he moved to Cornwall with his wife and began writing full-time, publishing his first novel, A Voyage to Arcturus, in 1920. Although the science fiction novel initially sold less than 600 copies, it has come to be known as a major "underground" novel of the 20th century, and heavily influenced C.S. Lewis's "Out of the Silent Planet". The story is set at Tormance, an imaginary planet orbiting Arcturus, where an adventurous Scot named Muskall has travelled and where he encounters myriad characters and lands that reflect Lindsay's critique of various philosophical systems.
