“The universality of card-playing in the reign of this monarch is evident from a prohibitory statute being necessary to prevent apprentices from using cards except in the Christmas holidays, and then only in their masters' houses…But this moderation, I apprehend, was by no means general, for several contemporary writers are exceedingly severe in their reflections upon the usage of cards, which they rank with dice, and consider both as destructive to morality and good order.”

Context: It’s a game of a million inferences. There are a lot of things to draw inferences from — cards played and not played. These inferences tell you something about the probabilities. It's got to be the best intellectual exercise out there. You're seeing through new situations every ten minutes. Bridge is about weighing gain/loss ratios. You're doing calculations all the time.
