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.
