How much stranger is the interplay of life among the elements, than any chemical interplay among the elements themselves. Life—and salt—and phosphorus—and the sea—and the moon. Life—and sulphur—and carbon—and volcanoes—and the sun. The way up, and the way down. The strange ways of life.

But Dana went home, to be a lawyer, and a rather dull and distinguished citizen. He was once almost an ambassador. And pre-eminently respectable.

He had been. He KNEW. He had even told us. It is a great achievement.

And then what?—Why, nothing. The old vulgar hum-drum. That's the worst of knowledge. It leaves one only the more lifeless. Dana lived his bit in two years, and knew, and drummed out the rest. Dreary lawyer's years, afterwards.

We know enough. We know too much. We know nothing.

Let us smash something. Ourselves included. But the machine above all.

Dana's small book is a very great book: contains a great extreme of knowledge, knowledge of the great element.

And after all, we have to know all before we can know that knowing is nothing.

Imaginatively, we have to know all: even the elemental waters. And know and know on, until knowledge suddenly shrivels and we know that forever we don't know.

Then there is a sort of peace, and we can start afresh, knowing we don't know.
