“If there are no sandpits from which it can be dug, then we must sift it out from river beds or from gravel or even from the sea beach. This kind however has these defects when used in masonry”

Context: Economy denotes the the proper management of materials and of site, as well as a thrifty balancing of cost and common sense in the construction of works.... the architect does not demand things which cannot be found or made ready without great expense. For example: it is not everywhere that there is plenty of pitsand, rubble, fir, clear fir, and marble... Where there is no pitsand, we must use the kinds washed up by rivers or by the sea... and other problems we must solve in similar ways.

The Use of Life (1894), ch. IV: Recreation

A Tritical Essay upon the Faculties of the Mind (1707)
Context: ALL Rivers go to the Sea, but none return from it. Xerxes wept when he beheld his Army, to consider that in less than a Hundred Years they would be all Dead. Anacreon was' Choakt with a Grape-stone, and violent Joy Kills as well as violent Grief. There is nothing in this World constant but Inconstancy; yet Plato thought that if Virtue would appear to the World in her own native Dress, all Men would be Enamoured with her. But now since Interest governs the World, and Men neglect the Golden Mean, Jupiter himself, if he came on the Earth would be Despised, unless it were as he did to Danae in a Golden Shower. For Men nowadays Worship the Rising Sun, and not the Setting.

"Order reigns in Berlin", Last written words. Collected Works 4 <!-- p. 536 -->
Context: The leadership has failed. Even so, the leadership can and must be recreated from the masses and out of the masses. The masses are the decisive element, they are the rock on which the final victory of the revolution will be built. The masses were on the heights; they have developed this 'defeat' into one of the historical defeats which are the pride and strength of international socialism. And that is why the future victory will bloom from this 'defeat'.
'Order reigns in Berlin!' You stupid henchmen! Your 'order' is built on sand. Tomorrow the revolution will already 'raise itself with a rattle' and announce with fanfare, to your terror: I was, I am, I will be!

Gift from the Sea (1955)
Context: The sea does not reward those who are too anxious, too greedy, or too impatient. To dig for treasures shows not only impatience and greed, but lack of faith. Patience, patience, patience, is what the sea teaches. Patience and faith. One should lie empty, open, choiceless as a beach — waiting for a gift from the sea.
