Wonder is defined by Thomas [Aquinas] in the Summa Theologiae [I-II, Q. 32, a. 8], as the desiderium sciendi, the desire for knowledge, active longing to know.
[I]f knowing is work, exclusively work, then the one who knows, knows only the fruit of his own, subjective activity, and nothing else. There is nothing in his knowing that is not the fruit of his own efforts; there is nothing "received" in it. […]It is the mark of "absolute activity" (which Goethe said "makes one bankrupt, in the end"); the hard quality of not-being-able-to-receive; a stoniness of heart, that will not brook any resistance — as expressed once, most radically, in the following terrifying statement: "Every action makes sense, even criminal acts ... all passivity is senseless."Josef Pieper
In our bourgeois Western world total labor has vanquished leisure. Unless we regain the art of silence and insight, the ability for non-activity, unless we substitute true leisure for our hectic amusements, we will destroy our culture—and ourselves.Josef Pieper
Now the code of life of the High Middle Ages said something entirely opposite to this: that it was precisely lack of leisure, an inability to be at leisure, that went together with idleness; that the restlessness of work-for-work's sake arose from nothing other than idleness. There is a curious connection in the fact that the restlessness of a self-destructive work-fanatacism should take its rise from the absence of a will to accomplish something.Josef Pieper
He who knows does not feel wonder. It could not be said that God experiences wonder, for God knows in the most absolute and perfect way.Josef Pieper
All just order in the world is based on this, that man give man what is his due.Josef Pieper
