The world is animated. In regards to religion, Campanella maintains that all positive religions are interpretations of natural religion. Only the Christian religion, which is supernatural, satisfies all the exigencies of natural religion. The others are deficient. In politics, Campanella's thought is in favor of a universal society, with the Pope as head of the religious aspects and the King of Spain as head of the civil.
Power is governed by knowledge.
The papacy is a monarchy of religious unity dominating the secular State and education must be universal and compulsory, and based on natural science and mathematics. Campanella, a member of the Dominican Order, was persecuted by the Inquisition. He spent twenty-seven years of his life in prison on account of his political ideas although he never attempted to put them into practice. The thinkers of the Middle Ages, preoccupied with the universal and the transcendent, neglected the study of the positive sciences. To avoid these errors, it is necessary that both metaphysics and the sciences stay within their limits.
