Custom determines what is agreeable.

We are more sensible of what is done against custom than against nature.

The universality of a custom is pledge of its worth.

There is nothing sacred about convention: there is nothing sacred about primitive passions or whims; but the fact that a convention exists indicates that a way of living has been devised capable of maintaining itself.

Often a quite assified remark becomes sanctified by use and petrified by custom; it is then a permanency, its term of activity a geologic period.

When in Rome, live as the Romans do; when elsewhere, live as they live elsewhere.

The way of the world is to make laws, but follow customs.

Custom is a second law.

How many things, just and unjust, have no higher sanction than custom!
