“Desire for goodness, Mister Reese, leads to earnestness. Earnestness in turn leads to sanctimonious self-righteousness, which breeds intolerance, upon which harsh judgment quickly follows, yielding dire punishment, inflicting general terror and paranoia, eventually culminating in revolt, leading to chaos, then dissolution, and thus, the end of civilisation.”

He slowly turned, looked down upon Emancipor.
“And we are creatures dependent upon civilisation. It is the only environment in which we can thrive.”

Emancipor frowned.
“The desire for goodness leads to the end of civilisation?”

“Precisely, Mister Reese.”

“But if the principal aim is to achieve good living and health among the populace, what is the harm in that?”

Bauchelain sighed.

“Very well, I shall try again. Good living and health, as you say, yielding well-being. But well-being is a contextual notion, a relative notion. Perceived benefits are measured by way of contrast. In any case, the result is smugness, and from that an overwhelming desire to deliver conformity among those perceived as less pure, less fortunate—the unenlightened, if you will. But conformity leads to ennui, and then indifference. From indifference, Mister Reese, dissolution follows as a natural course, and with it, once again, the end of civilisation.”
