STEFANO Every man shift for all the rest, andlet no man take care for himself; for all isbut fortune. Coragio, bully-monster, coragio! (5.1.1)
Stefano, rather drunk, mistakes the saying "every man for himself." What he comes up with, though it's supposed to be funny, is actually a pretty apt description of court rules, which place the nobles' welfare before all others. Stefano unintentionally outlines the underlying difference between the pastoral and courtly world.
