“Time and space are modes by which we think and not conditions in which we live.”
Earliest source located that attributes this to Einstein is the 1975 book The Nature of Scientific Discovery: A Symposium Commemorating the 500th Anniversary of the Birth of Nicolaus Copernicus edited by Owen Gingerich, p. 585 http://books.google.com/books?id=Ub3gAAAAMAAJ&q=%22certainly+a+central%22#search_anchor. But long before that, the 1944 book Einstein: An Intimate Study of a Great Man by Dimitri Marianoff and Palma Wayne contains the following quote on p. 62: "But Einstein came along and took space and time out of the realm of stationary things and put them in the realm of relativity—giving the onlooker dominion over time and space, because time and space are modes by which we think and not conditions in which we live." It appears from the quote that the authors were giving their own description of Einstein's ideas, not quoting him.
