Works

Position

Bruno took Copernicus far beyond astronomy. If the earth is not the centre, he argued, there is no centre at all: the universe is infinite and filled with countless suns and worlds, perhaps inhabited. An infinite God must express himself in an infinite creation. God is not outside the world but present in it as its soul and inner principle, so that the one living substance unfolds in all things – a view close to pantheism. Bruno also drew on Hermetic and magical traditions. His execution made him a symbol of free thought, and his ideas anticipated Spinoza and the modern picture of the cosmos.

Life & context

Born in 1548 in Nola near Naples, Bruno entered the Dominican order but fled in 1576 when suspected of heresy. He wandered through Geneva, Toulouse, Paris, London, Wittenberg, Prague and Frankfurt, teaching memory arts and publishing bold dialogues. Lured back to Venice in 1591, he was handed to the Roman Inquisition, refused to recant after years of trial, and was burned in Rome in 1600.
