 Hume’s account is another example of an analysis of hope as a passion—modified, however, by the specific approach he takes to human psychology. For Hume, hope is a “direct passion” that is produced when the mind considers events that have a probability between absolute certainty and absolute impossibility. Hume describes probability-beliefs as an effect of the mind entertaining contrary views—of an event or object as either existent or non-existent—in quick succession after another. Each of these views gives rise to either joy or sorrow (when the object is something good or bad) which linger longer in the mind than the original imagination of the object’s existence or non-existence. When considering objects that are probable, but not certain, the mind is thus affected by a mixture of joy and sorrow that, depending on the predominant element, can be called hope or fear.
