Blackstone’s Commentaries on the Laws of England are available in full here. And here is a lovely passage from the very beginning of the Commentaries:
This, then, is the general signification of law, a rule of action dictated by some superior being; and, in those creatures that have neither the power to think, nor to will, such laws must be invariably obeyed, so long as the creature itself subsists, for its existence depends on that obedience. But laws, in their more confined sense, and in which it is our present business to consider them, denote the rules, not of action in general, but of human action or conduct; that is, the precepts by which man, the noblest of all sublunary beings, a creature endowed with both reason and free-will, is commanded to make use of those faculties in the general regulation of his behaviour.
Man, considered as a creature, must necessarily be subject to the laws of his Creator, for he is entirely a dependent being. A being, independent of any other, has no rule to pursue, but such as he prescribes to himself; but a state of dependence will inevitably oblige the inferior to take the will of him on whom he depends as the rule of his conduct; not, indeed, in every particular, but in all those points wherein his dependence consists. This principle, therefore, has more or less extent and effect, in proportion as the superiority of the one and the dependence of the other is greater or less, absolute or limited. And consequently, as man depends absolutely upon his Maker for every thing, it is necessary that he should, in all points, conform to his Maker’s will.
