In a field of ripening corn I came to a place which had been trampled down by some ruthless foot; and as I glanced amongst the countless stalks, every one of them alike, standing there so erect and bearing the full weight of the ear, I saw a multitude of different flowers, red and blue and violet. How pretty they looked as they grew there so naturally with their little foliage! But, thought I, they are quite useless; they bear no fruit; they are mere weeds, suffered to remain only because there is no getting rid of them. And yet, but for these flowers, there would be nothing to charm the eye in that wilderness of stalks. They are emblematic of poetry and art, which, in civic life—so severe, but still useful and not without its fruit—play the same part as flowers in the corn.

The hazardous part of the business is also the mere possibility, still to be admitted, that the ultimate insight into the nature of things attainable by man, into his very being and that of the world, might not coincide exactly with the doctrines which were in part made known to the former little race of the Jews and in part appeared in Jerusalem eighteen hundred years ago.
