I can say, if I like, that social insects behave like the working parts of an immense central nervous system: the termite colony is an enormous brain on millions of legs; the individual termite is a mobile neurone.
Interpretation
The quote likens a termite colony to a vast nervous system, emphasizing the interconnectedness and collective function of its individual members.
In this quote, Lewis Thomas draws an intriguing parallel between the functioning of social insects, particularly termites, and the human brain's neural network. By describing the colony as an 'enormous brain on millions of legs,' he highlights the intricate organization and cooperation among termites, suggesting that each individual termite acts as a neuron, contributing to a greater collective intelligence, much like how neurons in a brain work together to facilitate thought, action, and coordination within an organism.
In practice
In a lecture about ecosystems, this quote could illustrate the organization of social insects.
I suggest that the introductory courses in science, at all levels from grade school through college, be radically revised. Leave the fundamentals, the so-called basics, aside for a while, and concentrate the attention of all students on the things that are not known.
I maintain, despite the moment's evidence against the claim, that we are born and grow up with a fondness for each other, and we have genes for that. We can be talked out of it, for the genetic message is like a distant music, and some of us are hard-of-hearing. Societies are noisy affairs, drowning out the sound of ourselves and our connection.
Science is founded on uncertainty. Each time we learn something new and surprising, the astonishment comes with the realization that we were wrong before.
It is the very strangeness of nature that makes science engrossing. That ought to be at the center of science teaching. There are more than seven-times-seven types of ambiguity in science, awaiting analysis. The poetry of Wallace Stevens is crystal-clear alongside the genetic code.
In the fields I know best, among the life sciences, it is required that the most expert and sophisticated minds be capable of changing course - often with a great lurch - every few years.
The earliest sensation at the onset of illness, often preceding the recognition of identifiable symptoms, is apprehension. Something has gone wrong, and a glimpse of mortality shifts somewhere deep in the mind. It is the most ancient of our fears.
Our tools are better than we are, and grow better faster than we do. They suffice to crack the atom, to command the tides, but they do not suffice for the oldest task in human history, to live on a piece of land without spoiling it.
It was kind of a beautiful day, finally real summer in Indianapolis, warm and humid - the kind of weather that reminds you after a long winter that while the world wasn't built for humans, we were built for the world.
The garden has taught me to live, to appreciate the times when things are fallow and when they're not.
...but I preferred reading the American landscape as we went along. Every bump, rise, and stretch in it mystified my longing.
To a naturalist nothing is indifferent; the humble moss that creeps upon the stone is equally interesting as the lofty pine which so beautifully adorns the valley or the mountain: but to a naturalist who is reading in the face of the rocks the annals of a former world, the mossy covering which obstructs his view, and renders indistinguishable the different species of stone, is no less than a serious subject of regret.
The industrial processes in use today were developed at a time when no one had to consider what the environmental impact was. Who cared? But making ecological concerns matter to a company's bottom line will help it do the research and development that will reinvent everything we buy.
