So ignorance is the want of knowledge, error is the want of guidance, forgetfulness is the want of remembrance, foolishness is the want of understanding: All these are nothing in themselves and have no positive existence.

 As for sensible realities, these are also purely good, and evil is merely their non-existence; that is, blindness is the want of sight, deafness is the want of hearing, poverty is the want of wealth, illness is the want of health, death is the want of life, and weakness is the want of strength." ...
