Now the good which is difficult or arduous, considered as good, is of such a nature as to produce in us a tendency to it, which tendency pertains to the passion of hope; whereas, considered as arduous or difficult, it makes us turn from it; and this pertains to the passion of despair.

Context

“Wherefore, in the concupiscible passions, there can be no contrariety of approach and withdrawal in respect of the same object.
On the other hand, the object of the irascible faculty is sensible good or evil, considered not absolutely, but under the aspect of difficulty or arduousness. Now the good which is difficult or arduous, considered as good, is of such a nature as to produce in us a tendency to it, which tendency pertains to the passion of hope; whereas, considered as arduous or difficult, it makes us turn from it; and this pertains to the passion of despair. In like manner the arduous evil, considered as an evil, has the aspect of something to be shunned; and this belongs to the passion of fear: but it also contains a reason for tending to it, as attempting something arduous, whereby to escape being subject to evil; and this tendency is called daring.” source
