““His work is as it were, a sacred object and the true fruit of his life, and his aim in storing it away for a more discerning posterity will be to make it the property of mankind. An aim like this far surpasses all others, and for it he wears the crown of thorns which is one day to bloom into a wreath of laurel. All his powers are concentrated in the effort to complete and secure his work; just as the insect, in the last stage of its development, uses its whole strength on behalf of a brood it will never live to see; it puts its eggs in some place of safety, where, as it well knows, the young will one day find life and nourishment, and then dies in confidence.””
