“The mental capacity of a person to make reasonable contracts, is the only criterion, by which to determine his legal capacity to make obligatory contracts. And his mental capacity to make reasonable contracts is certainly not to be determined by the fact that he is, or is not, twenty-one years of age.”

“Any government, that is its own judge of, and determines authoritatively for the people, what are its own powers over the people, is an absolute government of course.
