The psychic entropy peculiar to the human condition involves seeing more to do than one can actually accomplish and feeling able to accomplish more than what conditions allow. But this becomes possible only if one keeps in mind more than one goal at a time, being aware at the same time of conflicting desires. It can happen only when the mind knows not only what is but also what could be. The more complex any system, the more room it leaves open for alternatives, and the more things can go wrong with it.
