Anti-pelagian Writings by St. Augustine
Chapter 17 [XII.]--A Twofold Question to Be Treated Concerning the Soul; Is It |Body|? and is It |Spirit|? What Body is.
And now, as far as the Lord vouchsafes to enable me, I must reply also to that allegation of yours, in which, speaking of the soul, you again mention my name, and say, |We do not, as the very able and learned bishop Augustin professes, allow it to be incorporeal and also a spirit.| We have therefore, first, to discuss the question, whether the soul is to be deemed incorporeal, as I have said; or corporeal, as you hold. Then, secondly, whether in our Scriptures it is called a spirit -- although not the whole but its own separate part is also properly called spirit. Well, I should, to begin with, like to know how you define body. For if that is not |body| which does not consist of limbs of flesh, then the earth cannot be a body, nor the sky, nor a stone, nor water, nor the stars, nor anything of the kind. If, however, a |body| is whatever consists of parts, whether greater or less, which occupy greater or smaller local spaces, then all the things which I have just mentioned are bodies; the air is a body; the visible light is a body; and so are all the things which the apostle has in view, when he says, |There are celestial bodies, and bodies terrestrial.|
