If we consider games of chance immoral, then every pursuit of human industry is immoral; for there is not a single one that is not subject to chance, not one wherein you do not risk a loss for the chance of some gain... In all these pursuits, you take some one thing against another which you hope to win... These, then, are games of chance. Yet so far from being immoral, they are indispensable to the existence of man, and every one has a natural right to choose for his pursuit such one of them as he thinks most likely to furnish him subsistence.
