SUCH MATHEMATICAL SENSES CANNOT BE APPLIED TO THE SOUL.
When dealing with numbers and geometrical figures, as well as with bodies, it is evident that the whole is necessarily diminished by its division into parts, and that each part is smaller than the whole. Rightly, these things should be susceptible to increase or diminution, as their nature is that of definite quantities, not quantity in itself. It is surely not in this sense that, when referring to the soul, we speak of quantities. The soul is not a quantity such as a "dozen," which forms a whole divisible into unities; otherwise, we would end in a host of absurdities, since a group of ten is not a genuine unity. Either each one of the unities would have to be soul, or the Soul herself result from a sum of inanimate unities.
