Tolerance and indifference. Drucker makes much of these qualities. They are truly useful. Are you tolerant of a minority group if they do things that you approve? Probably not. You have to be willing to let them hold a divergent view.
Do you live in a free society if you are indifferent about certain aspects? This is important because Drucker talks about technical questions as being things of indifference to most of society. Do you make a free judgment when you determine the best way to organize knowledge or process data or make judgments from data, even if those actions have moral consequences? At this point in his career Drucker would say no but we will see what happens as he begins to conceive the importance of information in society.
