Among the propositions in mathematics
though many there
are that are in the strictest
sense useful and most abundantly
useful: yet many
are they there, in a word, all geometrical
ones – no one of which
is in the strict sense true.
True in this strict sense a
mathematical proposition
cannot be unless of the
sort of things which
is the subject of it some one
individual at least is to be
found. But of the sort of
things which are the subjects
of geometrical propositions
there is not perhaps one to
the description given by which any
individual ever can or ever
will be found exactly conformable.
But at the same time among
them those which have been
commonly taken for the subjects
of general geometrical propositions, many
there are – not to say all – to the description
given by which, individuals
hearing a relation
so near to that of exact
conformity as that it without
any practical inconvenience the
conformity may be taken for
considered as exact, ever have
been and ever will be found in
countless multitudes. No sphere
