Quote #4
And also a duty of one shilling for every twenty shillings, in any sum exceeding fifty pounds, which shall be given, paid, contracted, or agreed, for, with or in relation to any such clerk, or apprentice. (2.1)
This specifies a duty paid to an apprentice, which brings up an important point: duty as a concept goes both ways. People without power have duties to those who do, but people who have power also have duties to those who don't. This intersecting and interacting web of obligation is what we call society.
Quote #5
And be it further enacted by the authority aforesaid, That all books and pamphlets serving chiefly for the purpose of an almanack, by whatsoever name or names intituled [sic] or described, are and shall be charged with the duty imposed by this act on almanacks, but not with any of the duties charged by this act on pamphlets, or other printed papers; anything herein contained to the contrary notwithstanding. (5.1)
It's not enough to say that one has a duty to someone or something else. You have to specify what that duty is. This section of the law is one of several that clarifies what those are.
