The lessons of science should be experimental also. The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow outvalues all theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry.
Ralph Waldo EmersonPassion, though a bad regulator, is a powerful spring. Any absorbing passion has the effect to deliver from the little coils and cares of every day: 'tis the heat which sets our human atoms spinning, overcomes the friction of crossing thresholds, and first addresses in society, and gives us a good start and speed, easy to continue, when once it is begun.
