In one stroke, Galileo gained more with his new strategy than he had in years of begging. The reason is simple: All masters want to appear more brilliant than other people.

They do not care about science or empirical truth or the latest invention; they care about their name and their glory. Galileo gave the Medicis infinitely more glory by linking their name with cosmic forces than he had by making them the patrons of some new scientific gadget or discovery.

Scientists are not spared the vagaries of court life and patronage. They too must serve masters who hold the purse strings. And their great intellectual powers can make the master feel insecure, as if he were only there to supply the funds--an ugly, ignoble job. The producer of a great work wants to feel he is more than jus the provider of the financing. He wants to appear creative and powerful, and also more important than the work produced in his name. Instead of insecurity you must give him glory. Galileo did not challenge the intellectual authority of the Medicis with his discovery, or make them feel inferior in any way; by literally aligning them with the stars, he made them shine brilliantly among the courts of Italy. He did not outshine the master, he made the master outshine all others.
