One of the last true polymaths, able to be at the forefront of several fields, and an early exponent of bringing science to the (educated, non-scientific) people, Humboldt was a colossal global celebrity in his day whose star has waned as his ideas have been updated or superseded. Another factor working against him is the sheer volume and meticulous detail of his writings, even the ones intended for the wider public. This Everyman selection is an excellent attempt to bring Humboldt back into focus.

The basis of Humboldt's career, and of much of his oeuvre, was his expedition to the Americas from 1799-1804. Half of this volume is given up to his "personal narrative" of the trip, which unfortunately only covered the first part of it, to what is now Venezuela where he journeyed along the Orinoco and other tropical rivers before heading for a stop in Cuba. Despite its being cut short I found this the most readable text in the selection, largely thanks to judicious abridgment of the lengthier and more abstruse technical speculations. What makes it a pleasure is Humboldt's unbounded curiosity about everything, and the way his scientific lens only enhances his delight in the beauty of what he discovers. He rarely mentions the difficulty and dreadfulness of spending months living in a dug-out canoe with little or no respite from clouds of mosquitoes, water-borne parasites, etc., but admirers of boys' own exploration tales will find a bit of that here, too. If only we had the same day-by-day account, combining minor incidents with notable observations and scientific theory, of the rest of his trip which covered Mexico, Colombia, and the Inca territories.

Then we have excerpts from six other Humboldt works, some better than others. The "Essay on the Geography of Plants" expounds what was perhaps Humboldt's greatest scientific achievement, the understanding of how climate zones influence flora, and how these zones can be defined. Despite this it isn't a great read for the layman, suffering like all his writings from the fact that its value now is more as a historical document than a useful piece of science writing.

"Views of Nature" demonstrates the more romantic side of the man, as he sketches various scenes from his experiences in the "torrid zone". The short description of dusk and night in the middle of the rainforest will stay with me.

Then we have "Views of the Cordilleras and Monuments of the Indigenous Peoples of the Americas", which for me was the other highlight of this volume. Unfortunately, the beautiful engravings which accompanied the original text can't be properly represented in a book like this, but the reproductions at least give you some idea. Humboldt's writing is compelling, too, and his open-mindedness and respect (mostly) for indigenous cultures is very evident.

The selection from the "Political Essay on the Island of Cuba" is the chapter on slavery which was removed, to Humboldt's chagrin, from a U.S. edition. It is a strong indictment of the practice, on political and economic as well as moral grounds, which deserves a wider audience.

Finally, there is a part of his magnum opus, "Cosmos, Sketch of a Physical Description of the Universe". Wisely the editor has left out the actual physical description of the universe, which although doubtless a fascinating read in its time (and rather groundbreaking) will be old news or simply wrong to us. What we have instead is a couple of early parts of the work: first, an introductory text detailing his ur-philosophy of multi-disciplinarism and how the various sciences can only enhance each other, the interconnectedness of things and how increased understanding of natural phenomena should enhance rather than diminish our sense of wonder - all thoroughly modern (and secular) ideas. Then there's a survey of the representation of nature in literature from the earliest times, which I really enjoyed, especially the stirring eulogia of nature in scripture and of Camoens' Lusiads, along with brief discussions of nature in landscape painting and the cultivation of tropical plants.

Humboldt is a strange case of a great thinker, and in some ways great writer, who for very valid reasons has slipped into obscurity. His strengths then are weaknesses now, and for magnifying the former and mitigating the latter I'm thankful to Andrea Wulf and the publishers of this book. Wulf apologises in her introduction for a couple of the translations which are old and slightly stilted, but this is no big deal for anyone a little familiar with Victorian English prose. ( )
