The better a man is, the more mistakes will he make - for the more new — Peter Drucker

"The tool user, provided the tool is made well, need not, and indeed should not, know anything about the tool."

"Communism is evil. Its driving forces are the deadly sins of envy and hatred."

"Decisions exist only in the present."

"Frederick W. Taylor was the first man in recorded history who deemed work deserving of systematic observation and study. On Taylors scientific management rests, above all, the tremendous surge of affluence in the last seventy-five years which has lifted the working masses in the developed countries well above any level recorded before, even for the well-to-do. Taylor, though the Isaac Newton (or perhaps the Archimedes) of the science of work, laid only first foundations, however. Not much has been added to them since – even though he has been dead all of sixty years."

"Engineers speak half–jokingly about Murphys Law: " If anything can go wrong, it will." But complexity stands under a second law as well. Let me call it Druckers law: "If one thing goes wrong, everything else will, and at the same time."

"There is a point at which a transformation has to take place."
