“On the highest physical good”
Given this blog’s title, it seems appropriate to quote Kant’s Anthropology from a Pragmatic Point of View:
But in this judging of laziness, one can often do much wrong to a human being. For nature has also wisely placed the aversion to continuous work in many a subject, an instinct that is beneficial both to the subject and to others … for, if laziness did not intervene, indefatigable malice would comit far more ill in the world than it does now.
