"Human attempts to construct moral order are always precarious: If righteousness too often leads to self-righteousness, the demand for justice can lead to one guillotine or another."

During all those years of experimentation and research, I never once made a discovery. All my work was deductive, and the results I achieved were those of invention, pure and simple. I would construct a theory and work on its lines until I found it was untenable. Then it would be discarded at once and another theory evolved. This was the only possible way for me to work out the problem.
