I’m always reluctant to flag quotes ascribed to famous individuals because there’s a pernicious tendency for quotations of unknown origin to be ascribed to famous individuals to imbue them with more force and authority. (See for example about 30% of the quotes ascribed to Abraham Lincoln and about 90% of those ascribed to John Kennedy.)
But here I’ll make exception. If you go by Google at least, it seems widely ascribed to Albert Einstein …
We can’t solve problems by using the same kind of thinking we used when we created them.
Anyone know the actual citation? I guess it’s possible that it is a translation from German, though it sounds like perhaps a quote from late in his life so perhaps it was originally in English.
