The Mind of a Biologist: Big Meanings in Tiny Animals

leave a comment »

It’s hard to know where to begin with a book like Lewis Thomas’ The Lives of a Cell: Notes of a Biology Watcher. As slim as a mystery novella (the chapters are very short, the longest a bare 9 pgs), Lives of a Cell is packed with low-key language that disguises world-changing ideas. It took me a week to read a book that would ordinarily have taken a day simply because each short chapter generated so much I needed to think about that I couldn’t digest more than one at a time. It was like eating a meal so brilliantly prepared, balanced, and spiced that even though there wasn’t much bulk to each course one didn’t want to disturb the pleasure of the last by moving onto the next until one’s mouth and taste buds had been thoroughly cleansed and were ready for the richness to follow.

For instance, the two macro-notions that more or less underpin the book each could – and most likely have – engendered many deep philosophical works that discussed the ins and outs, pros and cons from the many different directions each of them suggests. I can’t possibly do justice to them here. I barely have the space to explain them let alone the many and various lines of thought they open up.

For example, one of the book’s two major themes is the idea that it is possible that mankind is a sort of superorganism, that, like certain kinds of social insects, when organized into a social marcrocosm we become, like ants and termites, capable of far more than we could ever hope to accomplish on our own – when we are operating on what he calls “our conjoined intelligence”. In the chapter titled “On Societies as Organisms” he writes:

Ants are so much like human beings as to be an embarrassment. They farm fungi, raise aphids as livestock, launch armies into wars, use chemical sprays to alarm and confuse enemies, capture slaves. The familes of weaver ants engage in child labor, holding their larvae like shuttles to spin out the thread that sews the leaves together for their fungus garden. They exchange information ceaselessly. They do everything but watch television.

A solitary ant, afield, cannot be considered to have much of anything on his mind; indeed, with only a few neurons strung together by fibers, he can’t be imagined to have a mind at all, much less a thought. He is more like a ganglion on legs. Four ants together, or ten, encircling a dead moth on a path, begin to look more like an idea. They fumble and shove, gradually moving the food toward the Hill, but as though by blind chance. It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.

The concept of mankind as a single organism unaccountably split into its component parts with each individual retaining its species cohesion while at the same time celebrating itself as the owner of a unique piece of the puzzle is not new. The entomologist William Morton Wheeler coined the term “superorganism” in 1911 to explain the phenomenon of insect intelligence when grouped together and science fiction writers have been playing with the idea ever since. The most recent well-known example is probably the Borg. But for a biologist to be toying with such an unorthodox interpretation of scientific data is unusual in 2008 and was near unheard of in the 70′s when this book was written.

Nor is that the only heretical idea Mr Thomas had up his sleeve. Read the rest of this entry »
