Nothing tends so much to the advancement of knowledge as the application of a new instrument.

Nothing is so dangerous to the progress of the human mind than to assume that our views of science are ultimate, that there are no mysteries in nature, that our triumphs are complete and that there are no new worlds to conquer.

Every discovery opens a new field for investigation of facts, shows us the imperfection of our theories. It has justly been said, that the greater the circle of light, the greater the boundary of darkness by which it is surrounded.

Nothing tends so much to the advancement of knowledge as the application of a new instrument.

There are very few persons who pursue science with true dignity.

The wealth and prosperity of the country are only the comeliness of the body, the fullness of the flesh and fat; but the spirit is independent of them; it requires only muscle, bone and nerve for the true exercise of its functions. We cannot lose our liberty, because we cannot cease to think.

By science calmed, over the peaceful soul, Bright with eternal Wisdom's lucid ray, Peace, meek of eye, extends her soft control, And drives the puny Passions far away.
