The system should treat all user input as sacred.

I am confident that we can do better than GUIs because the basic problem with them (and with the Linux and Unix interfaces) is that they ask a human being to do things that we know experimentally humans cannot do well. The question I asked myself is, given everything we know about how the human mind works, could we design a computer and computer software so that we can work with the least confusion and greatest efficiency?

An interface is humane if it is responsive to human needs and considerate of human frailties.

A computer shall not harm your work or, through inaction, allow your work to come to harm.
