While I agree with the article on many points, I would make the case differently.
To me, the distinction is between Animating Documents and Legal Founding Documents. The Declaration is a national animating document. Commonsense was a cultural animating document. The former was adopted by the Continental Congress as a communication to the World but not as a government forming document. The latter was only a popular cultural tract.
In contract, the Constitution was a governing adopted document. Adopted by the Constitutional Convention and subsiquently by the States and their peoples.
Animating Documents can still contain principles that animate me today. But that doesn't give them the force of law or make the Constitution suddenly subject to "propositions" found in other documents created or popular our founding.
The Rationalistic-Left uses such tactics to subvert the Constitution and the Republic. From such comes the "seperation of church and state" because Jefferson cited that in a letter. From such comes the Privacy pernumbra wherein Abortion became a "right".
Metaphysical political schemes will kill our Republic.
