We assume things will always be as they always have been. When the rain starts, we assume the skies ultimately will clear; that’s the way it’s always been. When a war begins, we assume it will eventually end; that’s the way it’s always been. When we catch a cold, we assume there will come a time when we recover our health; that’s the way it’s always been.
These are reasonable assumptions, based on our experience. Yet history reminds us that change is constant.
