Context

“"When He compassed the sea with its bounds, and set a law to the waters, that they should not pass their limits." I answer that, We must speak otherwise of the law of man, than of the eternal law which is the law of God. For the law of man extends only to rational creatures subject to man. The reason of this is because law directs the actions of those that are subject to the government of someone: wherefore, properly speaking, none imposes a law on his own actions. Now whatever is done regarding the use of irrational things subject to man, is done by the act of man himself moving those things, for these irrational creatures do not move themselves, but are moved by others, as stated above” source
