although subtile, their body would be divisible, just like air which, though vaporous, is yet divided by a sword, a club, or any other solid body. Their spirit, however, would be indivisible, and like the human soul, entire in the whole and in each and every part of the body. Consequently, the division of their body by another body, as aforesaid, might occasion mutilation and even death, for the spirit, itself indivisible, could not animate both parts of a divided body. True, just as the parts of air, separated by the agency of a body, unite again as soon as that body is withdrawn, and constitute the same air as before, even so the parts of the body divided, as above-mentioned, might unite and be revived by the same spirit. But then, it must be inferred that those animals could not be slain by natural or artificial agencies: and it were more rational to keep to our first position; for, if sharing matter with other creatures, it is natural that they should be liable to suffer through those creatures, according to the common rule, and even unto death. 59. Sexta interrogatio est, an ipsorum corpora possent alia corpora penetrare, ut parietes, ligna, metalla, vitrum, etc., et an multa ipsorum possent in eodem loco materiali consistere, et ad quantum spatium extenderetur, seu restringeretur eorum corpus? 59.

Could many of them abide together on the same material spot, and to what space would their body extend or be restrained?
