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.
