Read it through once

A common sophism, which, like many others, depends on the abuse of a metaphorical expression to a literal purpose, has produced much of the confusion which has involved the theory of morals. It is said that no person is bound to be just or kind, if, on his neglect, he should fail to incur some penalty. Duty is obligation. There can be no obligation without an obliger. Virtue is a law, to which it is the will of the lawgiver that we should conform; which will we should in no manner be bound to obey, unless some dreadful punishment were attached to disobedience. This is the philosophy of slavery and superstition.
