“David Lindsay is at once one of the most remarkable and one of the most tragic figures in 20th-century literature. Anyone who is willing to read his work patiently, from that amazing fantasy A Voyage to Arcturus to the strange unfinished torso called The Witch, will agree that the man was a towering genius whose mind is cast in the same mould as that of Dostoevsky. The Philosophical Aphorisms published in 1972 in the Scottish magazine Lines reveal him as a thinker who deserves comparison with Nietzsche. His problem was simple. Ordinary technical ability, the literary talent that so many third-rate novelists possess in abundance, was denied to him. As a result, his works have simply failed to reach a wider audience, and remain confined to a small band of ardent admirers. For example, this novel, Sphinx, has been out of print ever since it first appeared in 1923. Yet anyone who is willing to take it seriously—that is, to put into it the same kind of energy he might put into reading acknowledged masterpieces like Joyce's Ulysses or Proust's Remembrance of Things Past—will agree that it is a work of power and originality, with a haunting quality that is uniquely its own.
Let me take a deep breath and try to summarise Lindsay's ideas, for the benefit of readers who are discovering him for the first time. The tremendous problems of his life tended to make him pessimistic. In his Philosophical Notes (263) he writes: 'Deep depression, even to the extent of a breaking heart; then a sudden flashing light of joy and defiance—that is when the Sublime appears in its elemental purity.’ Every writer knows what he means: immense disappointments that seem to drain all your courage and batter you to your knees, and then that sudden upsurge of pure strength and optimism that seems to sweep away all doubts. It was a sensation experienced over and over again by men I called (in my first book) 'Outsiders', men like Nietzsche, Van Gogh, Dostoevsky. The Outsider is a man who feels that he has somehow fallen between two stools: too intelligent to be a 'success' in the everyday world, yet not intelligent or forceful enough to compel the world to take him at his own valuation. A few Outsiders—the most pathetic—feel alienated because their physical appearance is repellant—like Victor Hugo's hunchback of Nôtre Dame or the philosopher Moses Mendelssohn. Edmond Rostand even treated the idea with a certain humour in Cyrano de Bergerac, whose noble spirit seems to be mocked by his monstrous nose. Lindsay himself was presentable enough as a human being, but his curious clumsiness with words, his inability to express his deepest ideas on paper, makes him an archetypal Outsider.
This deep sense of self-division led him to write Arcturus, with its fantastic power. The basic philosophy of the book is that 'this world' is vicious and trivial, a silly masquerade. The ‘beauty' that human beings regard so highly is, according to Lindsay, a sugary stupidity. Real 'truth' is to be found in the magnificence of unclimbed mountains, of the lonely sea and the sky, in the tremendous power of some of Beethoven's music. T.E. Lawrence once said with disgust that he had looked everywhere for a real 'meal' in literature, something that could fill his stomach, but could only find 'snacks' Lindsay felt exactly the same. And just as Lawrence tried to satisfy 'fellow seekers' with his marvellous Seven Pillars of Wisdom, so Lindsay made his own tremendous attempt to achieve 'the Sublime' in Arcturus.“ - Colin Wilson from his introduction to David Lindsay’s ‘Sphinx’
