2. All good or evil, whence-ever it arises, produces various passions and affections, according to the light, in which it is surveyed.
When good is certain or very probable, it produces Joy: When evil is in the same situation, there arises Grief or Sorrow.
When either good or evil is uncertain, it gives rise to Fear or Hope, according to the degrees of uncertainty on one side or the other.
Desire arises from good considered simply; and Aversion, from evil. The Will exerts itself, when either the presence of the good or absence of the evil may be attained by any action of the mind or body.
3. None of these passions seem to contain any thing curious or remarkable, except Hope and Fear, which, being derived from the probability of any good or evil, are mixt passions, that merit our attention.Proba-
