That lead man from the bottom where he plants

Foot first of all, to life's last ladder-top:

Arrived there, vain enough will seem the vaunts

Of those who say—"We scale the skies, then drop

To earth—to find, how all things there are loth

To answer heavenly law: we understand

The meteor's course, and lo, the rose's growth—

How other than should be by law's command!"

Would not you tell such—"Friends, beware lest fume

Offuscate sense: learn earth first ere presume
