SAPIR 861
But the final value of action, like that of books, and better than books, is that it is a resource. That great principle of Undulation in nature, that shows itself in the inspiring and expiring of the breath; in desire and satiety; in the ebb and flow of the sea; in day and night; in heat and cold; and, as yet more deeply ingrained in every atom and every fluid, is known to us under the name of Polarity,--these "fits of easy transmission and reflection," as Newton[53] called them, are the law of nature because they are the law of spirit.
