"How gladly would we understand every principle pertaining to science and art, and become thoroughly acquainted with every intricate operation of nature, and with all the chemical changes that are constantly going on around us! How delightful this would be, and what a boundless field of truth and power is open for us to explore! We are only just approaching the shores of the vast ocean of information that pertains to this physical world, to say nothing of that which pertains to the heavens, to angels and celestial beings, to the place of their habitation, to the manner of their life, and their progress to still higher degrees of perfection."

BRIGHAM YOUNG, Tabernacle, Great Salt Lake City, January 26, 1862 REPORTED BY G. D. WATT
