I suppose the perfection of any thing to be only the greatest the nature of that thing is capable of.
Thus a horse is more perfect than an oyster, yet the oyster may be a perfect oyster, as well as the horse a perfect horse.
And an egg is not so perfect as a chicken, nor a chicken as a hen; for the hen has more strength than the chicken, and the chicken more life than the egg—yet it may be a perfect egg, chicken, and hen.
If they mean a man cannot in this life be so perfect as an angel, it is true, for an angel by being incorporeal, is allowed some perfections we are at present incapable of, and less liable to some imperfections that we are liable to. If they mean a man is not capable of being so perfect here as he is capable of being in heaven, that may be true likewise.
But that a man is not capable of being so perfect here as he is capable of being here, is not sense; it is as if I should say, a chicken in the state of a chicken is not capable of being so perfect as a chicken is capable of being in that state.
In the above sense there may be a perfect oyster, a perfect horse, a perfect ship, why not a perfect man? that is, as perfect as his present nature and circumstances admit?
