The desirable things which the individuals of a people can not do, or can not well do, for themselves, fall into two classes: those which have relation to wrongs, and those which have not. Each of these branch off into an infinite variety of subdivisions.
The first---that in relation to wrongs---embraces all crimes, misdemeanors, and non-performance of contracts. The other embraces all which, in its nature, and without wrong, requires combined action, as public roads and highways, public schools, charities, pauperism, orphanage, estates of the deceased, and the machinery of government itself.
From this it appears that if all men were just, there still would be some, though not so much, need of government.
