We humans long for stability in a world where everything is in flux. Despite our wishes, the only certainty in life is constant change. Nothing will be the exactly the same tomorrow as it is today.
Rivers erode one bank while causing accretion on another. Just when we think we’ve settled into a safe existence, we lose a job, someone gets sick, a child is born, a parent dies. Some change is rapid and perceptible like technological innovation or a summer storm. Other changes take eons like the creation of mountains or smoothing of jagged rock.
