This explains why our proof will
unavoidably have a somewhat sophistical
appearance, one we will however do our
best to polish up. Let the reader not
become suspicious on this account, for
our proof is most easy to clarify and
confirm in concreto. - There are after all
a good many maxims in circulation on
this subject that all informed and
thoughtful people with no vested interest
in the opposite view accept and according
to which they judge others' and their
own actions. Now, if all of these maxims
can be easily and naturally deduced from
the principle we will be asserting, then this
will serve as a test of its validity, and it
will become clear that it is this very
principle that was at the root of all our
judgments in these matters, however obscure
and undeveloped they may have been.
To begin with, then, the principle: We
are the rightful owners of a thing the
appropriation of which by another is physically
impossible. This is a proposition that is
immediately self-evident and needs no further
proof. And now to the question: Is there
anything of this sort in a book?
