A government constituted upon the basis of parental authority, thus highly estimated and extensively applied, has certainly the advantage of being directly sanctioned by the immutable and ever-operating laws of nature, and must thereby acquire a degree of firmness and durability to which governments, founded on the fortuitous superiority of particular individuals, either in strength or abilities, and continued only through the hereditary influence of particular families, can never be expected to attain.
“thus highly estimated and extensively applied”,是修饰"government"还是"parental authority"?
