يميل الناس كثيرًا إلى الظن بأنّ الواقع هو حدّ الإمكان. يعتقدون أنّ كلّ ما أُنجز هو كلّ ما يمكن إنجازه.

“People are too prone to think that the actual is the limit of possibility. They believe that all that has been done is all that can be done.”Helen Keller — Out of the Dark: Essays, Lectures, and Addresses on Physical and Social Vision (1920)
