Men love newfangleness.

Invention breeds invention.

Our way lies not in human ingenuity, but in a return to God.

Progress,-the stride of God!

Not enjoyment, and not sorrow, Is our destined end or way; But to act, that each to-morrow Brings us farther than to-day.

The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
