To take the best decision in the present means to define the best strategy.
The past is an optional element that can allow us to take some actions, based in excuses like you did me the same.
But out of that the history is only an element to define the decision.
If the day before yesterday you receive an atomic bomb, the best decision is not to send another to him necessarily, if you assume that your decision is consequence of what happen in the past you are limiting your options of positive actions for the humanity.
It is about a discipline to understand the future is what you do in the present, and the past is something that happen as you liked or not, but what is important is what you want to get, and the best decision take the past and the history only if it is useful for your current strategy; that is the basement of the positive actions of the +association.
The foresight and responsibility are over any kind of reaction to past events.
