But if any one says that the flesh is the cause of all vices and ill conduct, inasmuch as the soul lives wickedly only because it is moved by the flesh, it is certain he has not carefully considered the whole nature of man. For "the corruptible body, indeed, weigheth down the soul."[9] Whence, too, the apostle, speaking of this corruptible body, of which he had shortly before said, "though our outward man perish,"[10] says, "We know that if our earthly house of this tabernacle were dissolved, we have a building of God, an house not made with hands, eternal in the heavens. For in this we groan, earnestly desiring to be clothed upon with our house which is from heaven: if so be that being clothed we shall not be found naked. For we that are in this tabernacle do groan, being burdened: not for that we would be unclothed, but clothed upon, that mortality might be swallowed up in life."[11] We are then burdened with this corruptible body; but knowing that the cause of this burdensomeness is not the nature and substance of the body, but its corruption, we do not desire to be deprived of the body, but to be clothed with its immortality. For then, also, there will be a body, but it shall no longer be a burden, being no longer corruptible. At present, then, "the corruptible body presseth down the soul, and the earthly tabernacle weigheth down the mind that museth upon many things," nevertheless they are in error who suppose that all the evils of the soul proceed from the body. Virgil, indeed, seems to express the sentiments of Plato in the beautiful lines, where he says,-- "A fiery strength inspires their lives, An essence that from heaven derives, Though clogged in part by limbs of clay, And the dull 'vesture of decay;'"[12] but though he goes on to mention the four most common mental emotions,--desire, fear, joy, sorrow,--with the intention of showing that the body is the origin of all sins and vices, saying,-- "Hence wild desires and grovelling fears, And human laughter, human tears, Immured in dungeon-seeming night, They look abroad, yet see no light,"[13]
