“Things past recovery
Are hardly cured with exclamations.”

Source: Scoundrel Time (1976), p. 150
Context: Sad is a fake word for me to be using, I am still angry that their reason for disagreeing with McCarthy was too often his crude methods.... Many of the anti-Communists were, of course, honest men. But none of them... has stepped forward to admit a mistake. It is not necessary in this country; they too know that we are a people who do not remember much. I have written here that I have recovered. I mean it only in a worldly sense because I do not believe in recovery. The past, with its pleasures, its rewards, its foolishness, its punishments, is there for each of us forever, and it should be.

On the issue of nuclear weapons, in England Their England : Monsters, Maniacs and Moore (1987) http://www.youtube.com/watch?v=Hv44V4d_fDQ
Context: It doesn’t even matter if we ever fire these missiles or not. They are having their effect upon us because there is a generation growing up now who cannot see past the final exclamation mark of a mushroom cloud. They are a generation who can see no moral values that do not end in a crackling crater somewhere. I’m not saying that nuclear bombs are at the root of all of it, but I think it is very, very naïve to assume that you can expose the entire population of the world to the threat of being turned to cinders without them starting to act, perhaps, a little oddly.
I believe in some sort of strange fashion that the presence of the atom bomb might almost be forcing a level of human development that wouldn’t have occurred without the presence of the atom bomb. Maybe this degree of terror will force changes in human attitudes that could not have occurred without the presence of these awful, destructive things. Perhaps we are faced with a race between the Four Horseman of the Apocalypse in one line and the 7th Cavalry in the other. We have not got an awful lot of mid ground between Utopia and Apocalypse, and if somehow our children ever see the day in which it is announced that we do not have these weapons any more, and that we can no longer destroy ourselves and that we’ve got to do something else to do with our time than they will have the right to throw up their arms, let down their streamers and let forth a resounding cheer.

also quoted by Brewster himself in his Treatise on Optics http://books.google.com/books?id=opYAAAAAMAAJ&printsec=frontcover#PPR4,M1 and by Dionysius Lardner as frontispiece or presentation of his works (see for example: Popular lectures on science and art http://books.google.com/books?id=uZ9LAAAAMAAJ&pg=PA3, Cabinet Cyclopaedia http://books.google.com/books?id=5T43oHhqyxUC&pg=RA1-PT7).
Context: It is not easy to devise a cure for such a state of things (the declining taste for science). The most obvious remedy is to provide the educated classes with a series of works on popular and practical science, freed from mathematical symbols and technical terms, written in simple and perspicuous language, and illustrated by facts and experiments which are level to the capacity of ordinary minds.

Variant: Multiple exclamation marks,' he went on, shaking his head, 'are a sure sign of a diseased mind.
