Such a method falls short of being a true metaphysics. Indeed, beginning with Galileo, this new physio-mathematics was to take the place of traditional metaphysics. This theory, proposed by Galileo and afterwards followed by John Locke in his noted distinction between primary and secondary qualities, was to become part of modern thought. Now, such mechanism is in opposition to the transcendence of God and hence in opposition to the very faith professed by Galileo. Consequently, the Galilean method must be considered as a method of science and not as a theory of knowledge, for knowledge is based on metaphysics.
Heavenly bodies are all spherical, and their movement is circular and uniform.
The sun is located at the center of the system, and the planets rotate around it. The earth is a planet and has a double movement, revolving daily around its own axis, and annually around the sun. Galileo was the announcer of this system. Moreover, there were failings on both sides. The members of the Commission of the Holy Office, according to the prejudice then in vogue, believed that the destruction of Aristotle's physics meant the ruin of his metaphysics as well, and that the whole body of medieval thought would crumble.
