It is impossible to get out of a problem by using the same kind of thinking that it took to get into it.

When I have one week to solve a seemingly impossible problem, I spend six days defining the problem. Then, the solution becomes obvious.

It is impossible to get anywhere without sinning against reason.

It is impossible to solve significant problems using the same knowledge that created them.
