8. If there were a body outside of our world, and if an eye observed
it from here without any obstacle, it is doubtful that the eye could
see that body, because the eye would have no affection common to it;
for community of affection is caused by the coherence of the single
organism (that is, the unity of the world). Since this community of
affection (or, sympathy), supposes that sense-objects and that the
senses belong to the single organism, a body located outside of the
world would not be felt, unless it were part of the world. In this
case, it would be felt. If it were not a part of the world, but yet
by its color and other qualities it was conformed to the organ that
was to cognize it, would it be felt? No, it would not be felt, that
is, if such a hypothesis (of a body located outside of the world)
were at all admissible. If however, anyone should refuse to admit
such a hypothesis, he would pretend that it is absurd that the eye
should not see the color located in front of it, and that the other
senses do not perceive the qualities before them. That is the reason
of its absurdity. For we are active or passive only because we are
integral parts of the single organism, and are located within it. Is
anything still left to be considered? If what we have said suffices,
our demonstration is finished; otherwise we shall have to give still
further proofs to support our proposition.
