Life is girt all round with a zodiac of sciences, the contributions of men who have perished to add their point of light to our sky. ... These road-makers on every hand enrich us. We must extend the area of life and multiply our relations. We are as much gainers by finding a property in the old earth as by acquiring a new planet.
Ralph Waldo EmersonOur day of dependence, our long apprenticeship to the learning of other lands, draws to a close. The millions, that around us arerushing into life, cannot always be fed on the sere remains of foreign harvests.
Ralph Waldo Emerson
