Trouble is not necessarily caused by people who think they are smart enough to improve things. Resolution, peace, and happiness are also caused by people who think they are smart enough to improve things. Being smart enough isn't necessarily a problem. The author has a limited definition of people who think they are smart enough and of what they will do. He also says that cunning and ingenuity make things worse -- they may make things better -- you never know. Understanding can be a problem when the need for it dominates the process and gets in the way of being open to see and learn. Realizing that the vast majority of all that is is not known, and most of it is not even knowable, gives me perspective on the smallness of what we know, and I feel awe in reflecting on that. Staying in the box of the fragmentary and superficial is trying to catch the unlimited in the limited, and that is foolishness. Going outside the box of the fragmentary and superficial and exploring the mystery of totality opens the possibility of getting a glimpse of the unlimited, which we are capable of as human beings and helps us realize what it is to be fully human.
