X. Devotion is love towards an object which astonishes us.

Explanation.—Astonishment arises from the novelty of the object. If, therefore, it should happen that we often imagine the object at which we are astonished, we shall cease to be astonished at it, and hence we see that the emotion of devotion easily degenerates into simple love.

XI. Derision is joy arising from the imagination that something we despise is present in an object we hate.

Explanation.—In so far as we despise a thing we hate do we deny its existence, and so far do we rejoice. But inasmuch as we suppose that a man hates what he ridicules, it follows that this joy is not solid.

XII. Hope is a joy not constant, arising from the idea of something future or past, about the issue of which we sometimes doubt.

XIII. Fear is a sorrow not constant, arising from the idea of something future or past, about the issue of which we sometimes doubt.

Explanation.—From these definitions it follows that there is no hope without fear nor fear without hope, for the person who wavers in hope and doubts concerning the issue of anything is supposed to imagine something which may exclude its existence, and so far, therefore, to be sad, and consequently while he wavers in hope, to fear lest his wishes should not be accomplished. So also the person who fears, that is to say, who doubts whether what he hates will not come to pass, imagines something which excludes the existence of what he hates, and therefore is rejoiced, and consequently so far hopes that it will not happen.

XIV. Confidence is joy arising from the idea of a past or future object from which cause for doubting is removed.

XV. Despair is sorrow arising from the idea of a past or future object from which cause for doubting is removed.

Explanation.—Confidence, therefore, springs from hope and despair from fear, whenever the reason for doubting the issue is taken away; a case which occurs either because we imagine a thing past or future to be present and contemplate it as present, or because we imagine other things which exclude the existence of those which made us to doubt.
