The Muslims Who Inspired Spinoza, Locke and Defoe

In this age of anxiety, anger and contestations between the West and the Islamic world, many epoch-shaping stories of intellectual exchanges between our cultures are often forgotten.

A powerful example comes from literature. Millions of Christian, Jewish and Muslim readers across the world have read that famed tale of the man stranded alone on an island: “Robinson Crusoe” by Daniel Defoe, the 18th-century British pamphleteer, political activist and novelist.

Few know that in 1708, 11 years before Defoe wrote his celebrated novel, Simon Ockley, an Orientalist scholar at Cambridge University, translated and published a 12th-century Arabic novel, “Hayy ibn Yaqzan,” or “Alive, the Son of Awake,” by Abu Bakr Muhammad ibn Tufayl, an Andalusian-Arab polymath. Writing about the influence of Ibn Tufayl’s novel on Defoe’s “Robinson Crusoe,” Martin Wainwright, a former Guardian editor, remarked, “Tufayl’s footprints mark the great classic.”

Ibn Tufayl’s novel tells the tale of Hayy, a boy growing up alone on a deserted island, with animals. As he grows up, Hayy uses his senses and reason to understand the workings of the natural world. He explores the laws of nature, devises a rational theology and entertains theories about the origin of the universe. He develops a sense of ethics: Out of mercy for animals, he turns vegetarian, and out of care for plants, he preserves their seeds.

Hayy then leaves his island and visits a religious society. He finds that the teachings of reason and religion are compatible and complementary. Yet he notices that some religious people may be crude, even hypocritical. He returns to his island, where he had found God and developed his concepts of truth, morality and ethics by relying on observation and reasoning.

Ibn Tufayl’s message was clear — and for its times, quite bold: Religion was a path to truth, but it was not the only path. Man was blessed with divine revelation, and with reason and conscience from within. People could be wise and virtuous without religion or a different religion.
