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.
There may be aliens in our Milky Way galaxy, and there are billions of other galaxies. The probability is almost certain that there is life somewhere in space.
I sometimes try to imagine what would have happened if we’d known the bonobo first and the chimpanzee only later—or not at all. The discussion about human evolution might not revolve as much around violence, warfare and male dominance, but rather around sexuality, empathy, caring and cooperation. What a different intellectual landscape we would occupy!
The best material model of a cat is another, or preferably the same, cat.
See first, think later, then test. But always see first. Otherwise you will only see what you were expecting. Most scientists forget that.
The best scientist is open to experience and begins with romance - the idea that anything is possible.
Our Western science, ever since the 17th century, has been obsessed with the notion of control, of man dominating nature. This obsession has led to disaster.
