Every materialist will be an idealist; but an idealist can never go backward to be a materialist.
Ralph Waldo EmersonAs we are, so we do; and as we do, so is it done to us; we are the builders of our fortunes.
Ralph Waldo EmersonThe 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 Emerson
