Meditation 4.21

21. You ask how, if souls continue to exist, the atmosphere has room for them from time eternal. But how does the ground have room for the bodies of those who for so long an age are buried in it? The answer is that, as on earth change and dissolution after a continuance for so long make room for other dead bodies, so in the atmosphere souls pass on and continue for so long, and then change and are poured out and are kindled being assumed into the generative principle of Universal Nature, and so provide room for those which succeed to their place. This would be the answer presuming that souls do continue. But we must consider not only the multitude of bodies that are thus buried, but also the number of animals eaten every day by ourselves and the rest of the animal creation. How large a number are devoured and in a manner of speaking buried in the bodies of those who feed upon them; and yet there is room to contain them because they are turned into blood, because they are changed into forms of air and heat. How shall we investigate the truth of this? By a distinction into the material and the causal.
