“So much was expected of the true strategist: a student of the present who must be aware of the past, sensitive to the possibilities of the future, conscious of the danger of bias, alert to ambiguity, alive to chaos, ready to think through consequences of alternative courses of action, and then able to articulate all this with sufficient precision for those who must execute its prescriptions.2 This was a counsel of perfection. There was only so much knowledge that an individual could accumulate, assimilate, and manipulate; only so many potential sequences of events that could be worked through in a system that was full of uncertainty, complexity, and chaos.”
