In the 17th century, before the Scientific Revolution, there was a cultural climate of complete obscurantism, derived from the Medieval conception of the world. In fact, the universe, according to this wiew, was teleological and followed the geocentric theory, which placed the Earth at the center of the solar system. The phylosophy was the Scholasticism. But around the half of the 17th century, with the advent of new ideas and theories, the scientific method becomes inductive, based on observation, hypotesis, verification (through experience) and clarification of the theory. The conception of the universe changes, it becomes heliocentric, putting the sun at the center of the solar system. Among the most famous scientists of the scientific revolution, we can remember Galileo Galilei, Copernicus, Newton, Kepler and Bacon. In the same century was born the royal society, which was made up of men of culture. This organization had the task of fighting against superstition, obscurantism and ignorance, and to promote peace in the world.
