James Madison (Father of Constitution), commenting about the "General Welfare" Clause

James Madison, the Father of the Constitution, elaborated upon this limitation in a letter to James Robertson:
With respect to the two words "general welfare," I have always regarded them as qualified by the detail of powers connected with them. To take them in a literal and unlimited sense would be a metamorphosis of the Constitution into a character which there is a host of proofs was not contemplated by its creators. If the words obtained so readily a place in the "Articles of Confederation," and received so little notice in their admission into the present Constitution, and retained for so long a time a silent place in both, the fairest explanation is, that the words, in the alternative of meaning nothing or meaning everything, had the former meaning taken for granted.
