A being with only good placed in view may be justly said to be impelled by a blind necessity.

The pursuit of good in this case can be no indication of virtuous propensities.

It might be said, perhaps, that infinite Wisdom cannot want such an indication as outward action, but would foreknow with certainly whether the being would choose good or evil.
This might be a plausible argument against a state of trial, but will not hold against the supposition that mind in this world is in a state of formation.

Upon this idea, the being that has seen moral evil and has felt disapprobation and disgust at it is essentially different from the being that has seen only good.

They are pieces of clay that have received distinct impressions: they must, therefore, necessarily be in different shapes; or, even if we allow them both to have the same lovely form of virtue, it must be acknowledged that one has undergone the further process, necessary to give firmness and durability to its substance, while the other is still exposed to injury, and liable to be broken by every accidental impulse.
