Attitude quotes

As quoted in Journal of France and Germany (1942–1944) by Gilbert Fowler White, in excerpt published in Living with Nature's Extremes: The Life of Gilbert Fowler White (2006) by Robert E. Hinshaw, p. 62. From the context http://books.google.com/books?id=_2qfZRp9SeEC&lpg=PP1&pg=PA62#v=onepage&q&f=false it seems that White did not specify whether he had heard Einstein himself say this or whether he was repeating a quote that had been passed along by someone else, so without a primary source the validity of this quote should be considered questionable.
Some have argued that elsewhere Einstein defined a "miracle" as a type of event he did not believe was possible—Einstein on Religion by Max Jammer (1999) quotes on p. 89 from a 1931 conversation Einstein had with David Reichinstein, where Reichinstein brought up philosopher Arthur Liebert's argument that the indeterminism of quantum mechanics might allow for the possibility of miracles, and Einstein replied that Liebert's argument dealt "with a domain in which lawful rationality [determinism] does not exist. A 'miracle,' however, is an exception from lawfulness; hence, there where lawfulness does not exist, also its exception, i.e., a miracle, cannot exist." ("Dort, wo eine Gesetzmässigkeit nicht vorhanden ist, kann auch ihre Ausnahme, d.h. ein Wunder, nicht existieren." D. Reichenstein, Die Religion der Gebildeten (1941), p. 21). However, it is clear from the context that Einstein was stating only that miracles cannot exist in a domain (quantum mechanics) where lawful rationality does not exist. He did not claim that miracles could never exist in any domain. Indeed, Einstein clearly believed, as seen in many quotations above, that the universe was comprehensible and rational, but he also described this characteristic of the universe as a "miracle". In another example, he is quoted as claiming belief in a God, "Who reveals Himself in the lawful harmony of the world."

'Where Do We Go From Here?" as published in Where Do We Go from Here : Chaos or Community? (1967), p. 62; many statements in this book, or slight variants of them, were also part of his address Where Do We Go From Here?" which has a section below. A common variant appearing at least as early as 1968 has "Returning violence for violence multiplies violence..." An early version of the speech as published in A Martin Luther King Treasury (1964), p. 173, has : "Returning hate for hate multiplies hate..."
1960s
Source: A Testament of Hope: The Essential Writings and Speeches
Context: The ultimate weakness of violence is that it is a descending spiral, begetting the very thing it seeks to destroy. Instead of diminishing evil, it multiplies it. Through violence you may murder the liar, but you cannot murder the lie, nor establish the truth. Through violence you may murder the hater, but you do not murder hate. In fact, violence merely increases hate. So it goes. … Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that.

Context: There is a revolution coming. It will not be like revolutions of the past. It will originate with the individual and with culture, and it will change the political structure only as its final act. It will not require violence to succeed, and it cannot be successfully resisted by violence. It is now spreading with amazing rapidity, and already our laws, institutions and social structure are changing in consequence. It promises a higher reason, a more human community, and a new and liberated individual. Its ultimate creation will be a new and enduring wholeness and beauty — a renewed relationship of man to himself, to other men, to society, to nature, and to the land.
This is the revolution of the new generation.

Context: The standard bearers have grown weak in the defense of their priceless heritage, and the powers of darkness have been strengthened thereby. Weakness of attitude becomes weakness of character; it becomes lack of power to act with courage proportionate to danger. All this must lead to the destruction of our intellectual life unless the danger summons up strong personalities able to fill the lukewarm and discouraged with new strength and resolution.

Letter to Isham Reavis (5 November 1855)
1850s
Context: If you are resolutely determined to make a lawyer of yourself, the thing is more than half done already. It is but a small matter whether you read with anyone or not. I did not read with anyone. Get the books, and read and study them till you understand them in their principal features; and that is the main thing. It is of no consequence to be in a large town while you are reading. I read at New Salem, which never had three hundred people living in it. The books, and your capacity for understanding them, are just the same in all places.... Always bear in mind that your own resolution to succeed, is more important than any other one thing.

As discussed in this entry from The Quote Investigator http://quoteinvestigator.com/2010/05/04/universe-einstein/#more-173, the earliest published attribution of a similar quote to Einstein seems to have been in Gestalt therapist Frederick S. Perls' 1969 book Gestalt Theory Verbatim, where he wrote on p. 33: "As Albert Einstein once said to me: 'Two things are infinite: the universe and human stupidity.' But what is much more widespread than the actual stupidity is the playing stupid, turning off your ear, not listening, not seeing." Perls also offered another variant in his 1972 book In and Out the Garbage Pail, where he mentioned a meeting with Einstein and on p. 52 http://books.google.com/books?id=HuxFAAAAYAAJ&q=human+stupidity#search_anchor quoted him saying: "Two things are infinite, the universe and human stupidity, and I am not yet completely sure about the universe." However, Perls had given yet another variant of this quote in an earlier book, Ego, Hunger, and Aggression: a Revision of Freud’s Theory and Method (originally published 1942, although the Quote Investigator only checked that the quote appeared in the 1947 edition), where he attributed it not to Einstein but to a "great astronomer", writing: "As modern times promote hasty eating to a large extent, it is not surprising to learn that a great astronomer said: 'Two things are infinite, as far as we know – the universe and human stupidity.' To-day we know that this statement is not quite correct. Einstein has proved that the universe is limited." So, the later attributions in 1969 and 1972 may have been a case of faulty memory, or of intentionally trying to increase the authority of the quote by attributing it to Einstein. The quote itself may be a variant of a similar quote attributed even earlier to the philosopher Ernest Renan, found for example in The Public: Volume 18 from 1915, which says on p. 1126 http://books.google.com/books?id=cTPmAAAAMAAJ&pg=PA1126#v=onepage&q&f=false: "He quotes the saying of Renan: it isn't the stars that give him an idea of infinity; it is man's stupidity." (Other examples of similar attributions to Renan can be found on this Google Books search http://www.google.com/search?q=renan+infinity+stupidity&btnG=Search+Books&tbm=bks&tbo=1.) Renan was French so this is presumably intended as a translation, but different sources give different versions of the supposed original French quote, such as "La bêtise humaine est la seule chose qui donne une idée de l'infini" (found for example in Réflexions sur la vie, 1895-1898 by Remy de Gourmont from 1903, p. 103 http://books.google.com/books?id=RtrtAAAAMAAJ&pg=PA103#v=onepage&q&f=false, along with several other early sources as seen in this search http://www.google.com/search?q=%22humaine+est+la+seule+chose+qui%22+renan&btnG=Search+Books&tbm=bks&tbo=1) and "Ce n'est pas l'immensité de la voûte étoilée qui peut donner le plus complétement l'idée de l'infini, mais bien la bêtise humaine!" (found in Broad views, Volume 2 from 1904, p. 465 http://books.google.com/books?id=9NEaAQAAMAAJ&pg=PA465#v=onepage&q&f=false). Since these variants have not been found in Renan's own writings, they may represent false attributions as well. They may also be variants of an even older saying; for example, the 1880 book Des vers by Guy de Maupassant includes on p. 9 http://books.google.com/books?id=cQUvAAAAMAAJ&pg=PP21#v=onepage&q&f=false a quote from a letter (dated February 19, 1880) by Gustave Flaubert where Flaubert writes "Cependant, qui sait? La terre a des limites, mais la bêtise humaine est infinie!" which translates to "But who knows? The earth has its boundaries, but human stupidity is infinite!" Similarly the 1887 book Melanges by Jules-Paul Tardivel includes on p. 273 http://books.google.com/books?id=n9cOAAAAYAAJ&pg=PA273#v=onepage&q&f=false a piece said to have been written in 1880 in which he writes "Aujourd'hui je sais qu'il n'y a pas de limites à la bêtise humaine, qu'elle est infinie" which translates to "today I know that there is no limit to human stupidity, it is infinite."
