Lincoln refused to accept that our nation’s sole purpose was mere survival. He created this academy, founded the land grant colleges, and began the work of the transcontinental railroad, believing that we must add—and I quote—“the fuel of interest to the fire of genius in the discovery … of new and useful things.”
