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.
Josef PieperHappiness and joy are not the same. For what does the fervent craving for joy mean? It does not mean that we wish at any cost to experience the psychic state of being joyful. We want to have reason for joy, for an unceasing joy that fills us utterly, sweeps all before it, exceeds all measure.
