Marginal Thinking

   It is an economic truism that changes occur at the margin. But while each change should be noted, not all are consequential.
   Marginal thinkers focus on changes at the edge, and too many assume that any shift at the margin inevitably brings change to the whole.
   Granted, sometimes it does. But sometimes is not always, and superimposing already held convictions, assumptions and Truths onto preconceived notions of what "should be" is a path of perceived glory that leads but to grave consequences.
   Therefore, examine each tree, but consider the effect of change on the entire forest, and remember that it may be minimal, monumental, or none.
