“We hold that no person or set of persons can properly establish a standard of expression for others.”

Off the top of my head, there is only one glaring exception to the rule (Jesus). The second half or follow up to that would be — only the justice as harmonizes with the laws of nature and of nature's God can stand as proper in defining individual actions of others (not a standard). Each standard of expression emirates from the individual. By way of thought, multiple body politic styles of administration can offer a standard establishment of expressions. Keynesian Economics is an established standard of expression for others BUT !   it is not proper within / by a standard of natural / common law, ultimate justice, prosperity for the many, liberty, inalienable rights and/or individual sovereignty.
