Abraham Lincoln Quote
Without the Constitution and the Union, we could not have attained the result; but even these, are not the primary cause of our great prosperity.

That something, is the principle of "Liberty to all" the principle that clears the path for all-gives hope to all-and, by consequence, enterprize [sic], and industry to all.
