“Humboldt's early biographer, F.A. Schwarzenberg, subtitled his life of Humboldt What May Be Accomplished in a Lifetime. He summarised the areas of his subject's extraordinary curiosity as follows: '1) The knowledge of the Earth and its inhabitants. 2) The discovery of the higher laws of nature, which govern the universe, men, animals, plants, minerals. 3) The discovery of new forms of life. 4) The discovery of territories hitherto but imperfectly known, and their various productions. 5)The acquaintance with new species of the human race--- their manners, their language and the historical traces of their culture.' What may be accomplished in a lifetime---and seldom or never is.”
