Famous quotes containing the words water, pressure and/or difference:
“People always ask us, “Are things better or worse today?” Well, some things are better and some things are worse.... But there are a lot of problems in the world today that no one dreamed of when we were young. For instance, this business about the environment. Why, clean water was just something you took for granted.”
—Sarah Delany (b. 1890)
“This is a catastrophic universe, always; and subject to sudden reversals, upheavals, changes, cataclysms, with joy never anything but the song of substance under pressure forced into new forms and shapes.”
—Doris Lessing (b. 1919)
“When I think of God, when I think of him as existent, and when I believe him to be existent, my idea of him neither increases nor diminishes. But as it is certain there is a great difference betwixt the simple conception of the existence of an object, and the belief of it, and as this difference lies not in the parts or composition of the idea which we conceive; it follows, that it must lie in the manner in which we conceive it.”
—David Hume (1711–1776)
