Today I find the first official continuance of the Second 100 Days. It is almost invisible what has provoked me to begin this again- though the motives are hardly different from the days and the origin of the first 100-, or these compelling ingredients are so far on the frontier of my own identity that I can hardly find them in my mental map.
   It is hardly a thing of matter as to why, but what does matter is the trend of why's - or y's, as I'll soon outline- because from trends, especially in the abstract concepts, is where wisdom is mined. Or mined. I'm full of these today.
   In effect the concept of calculus -note not 'calculus itself', but 'concept'- is the central to what I can draw from my own situation. The why's are the first derivative, explaining handily the not the exact current position of where I stand in my own actions, but in fact, where it is going from wherever I call here. It is dx/dy. But wisdom is not the velocity, so to speak, but really the acceleration- the ability to predict anything non linear through the trend of velocity. So, wisdom finds itself being the second derivative of the position equation. It allows the prediction of anything that is not directly understood through observation.
   I believe that the mathematical human mind is not one of really complicated calculus (anything exponential), but rather is king of linear estimation. The why's of any situation, if comprehended correctly, can estimate where something will be when if that's all there is to it. The velocity is simply a rate, and estimates a linear direction (if logic and foresight were melded into a graph). Lines are straight, and we naturally understand how fast something is going. For example, we have zero trouble following a baseball at 95 MPH with our eyes even though it has a hugely limited number of frames per second (meaning there's only datapoints being taken in). However, any human mind fills in the gaps, and this is why cartoons- and really pushing it, anime- are bearable.
  But wisdom is what not everyone is outfitted with and is therefore rare and finally therefore of utmost importance. People have no troubles  with their linear calculation programs, even if they only understand a simple two datapoints- they will instantly understand that one became the other in the straight and simple fashion of a line. Wisdom, or acceleration, or dy^2/dx, is insanely different and requires a method and rules. It cannot be fired from hip and must be done in order. You seldom see wisdom outside of those people who realize many trends bleeding into one simplified one.
  So, understanding the trend of the why's- or the explanations of events- can help predict the future and assess probable consequences. No wonder the wisest figures will most often remain ardent and lowly students of history, because they have everything condensed into event-reasoning-lesson/aphorism. It seems history is somehow the petri dish for this sort of thinking- and remember that calculus cannot skip a derivative, but must go from position to velocity to acceleration- because it is always structured, and many events, no matter how similar can yield much of a lesson without a similarity in the why's and a rough kinship (like "it's in the same family" kind of kinship) in position equation from which the wisdom is pulled.
  Therefore both similarity in the events of life and the reason why's must be scoured for coincidences (which are simply potential wisdom mine shafts) to draw the lesson that would otherwise go unnoticed in the world of linear thinkers.
