"The terms "general welfare" were doubtless intended to signify more than was expressed or imported in those which preceded; otherwise, numerous exigencies incident to the affairs of a nation would have been left without a provision.

“There is a certain enthusiasm in liberty, that makes human nature rise above itself in acts of bravery and heroism.”

The bowels as well as the surface of the earth are ransacked for articles which were before neglected. Animals, Plants and Minerals acquire an utility and value, which were before unexplored.”
