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.

The uniformity of the earth's life, more astonishing than its diversity, is accountable by the high probability that we derived, originally, from some single cell, fertilized in a bolt of lightning as the earth cooled.
Interpretation
Life on Earth shares a common origin, which is more surprising than its variety.
This quote by Lewis Thomas emphasizes the idea that while the variety of life on Earth is impressive, the fact that all living organisms share a common ancestral origin from a single cell is even more remarkable. The mention of a 'bolt of lightning' illustrates the dramatic and mysterious nature of the conditions that led to the beginnings of life, suggesting that our biological connections run deep, despite the vast diversity we see today.
In practice
In a science class discussion about the origins of life, this quote can inspire students to think about our shared beginnings.
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.
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.
[T]here are depths of thousands of miles which are hidden from our inquiry. The only tidings we have from those unfathomable regions are by means of volcanoes, those burning mountains that seem to discharge their materials from the lowest abysses of the earth.
I was the most emotional of the flight directors. Space really got me all honked up.
I venture to define science as a series of interconnected concepts and conceptual schemes arising from experiment and observation and fruitful of further experiments and observations. The test of a scientific theory is, I suggest, its fruitfulness.
A theory should not attempt to explain all the facts, because some of the facts are wrong
The sheer quantity of brain power that hurled itself voluntarily and quixotically into the search for new baseball knowledge was either exhilarating or depressing, depending on how you felt about baseball. The same intellectual resources might have cured the common cold, or put a man on Pluto.
That is the logical tight-rope on which we have to walk if we wish to interpret nature.
