A superior and commanding intellect, a truly great man-when Heaven vouchsafes so rare a gift-is not a temporary flame, burning for a while, and then expiring, giving place to eternal darkness. It is rather a spark of fervent heat, as well as radiant light, with power to enkindle the common mass of human mind; so that, when it glimmers in its own decay, and finally goes out in death, no night follows; but it leaves the world all light, all on fire, from the potent contact of its own spirit.
