Galileo's superiority over his rivals lies in the synthesis of mathematics and controlled experimentation. The latter was alien to Aristotle himself, who limited himself to observations and filled them with his peculiar metaphysical beliefs.
One of his peculiar metaphysical beliefs is that scientific knowledge of the world must be based on an inductive process over empirical data, not deductive logic over assumed postulates.

That one turned out rather well, don't you think?
The non-theoretical character of metaphysics would not be in itself a defect; all arts have this non-theoretical character without thereby losing their high value for personal as well as for social life. The danger lies in the deceptive character of metaphysics; it gives the illusion of knowledge without actually giving any knowledge. This is the reason why we reject it. - Rudolf Carnap "Philosophy and Logical Syntax"
