In my opinion, it was chiefly owing to their deep contemplation in their silent retreats in the days of youth that the old Indian orators acquired the habit of carefully arranging their thoughts. They listened to the warbling of birds and noted the grandeur and the beauties of the forest. The majestic clouds—which appear like mountains of granite floating in the air—the golden tints of a summer evening sky, and the changes of nature, possessed a mysterious significance. All of this combined to furnish ample matter for reflection to the contemplating youth.

The object of oratory alone in not truth, but persuasion.
Yeats was 18th-century oratory, almost.
