The

transition
from

(A)
to
case (B)
passes through
[the
case] u1
=
A:
Cap
within

the

0:[11]
By
the
way,
the
assumption
of
an
elliptic space
(identification
of two
diamet-
rical
points
on
the
sphere)
does
seem
far
more
natural
to
me
now,
after
all,
than
a
spherical
one.-[12]
Once
again,
most cordial
thanks
for
submitting
my paper
to
the
Academy![13]
The
corrected version
was
sent out to
you
a
few
days ago already.
Your
rejection
of the
theory
weighs
heavily
on me;
I
know
only
too
well
how much closer
a
contact
you
have with
reality
than
I.
But
my
own
brain
still
keeps
faith
in it.
And
as a
mathematician, I
absolutely
must adhere
to
this
much:
My geometry
is
the
true,
local
geometry
[Nahegeometrie];
the
fact
that
Riemann
just
arrived at
the
special
case
Fik
= 0[14]
has
merely
historical
reasons
(development
out
of
the
theory
of
surfaces),[15]
no
substantive
ones.
If in
the
end
you are
right
about
the
real
world,
then
I
would
regret having
to
accuse
God
Almighty
of
a
mathematical
inconsequence.[16]
I
hope
that
in
the
near
future
I
am
given
the
opportunity
of
discussing
this
more
thoroughly
with
you
in
person,
here in Zurich.
With
sincere
thanks and best
regards, yours,
H.
Weyl.

Dear
Professor,
You
are
the
only person
to whom
I
can
entrust
the
following
and the
only
one
who
can give
me
advice,
and
that
is
why
I
ask
you please
to
consider
carefully
what
I
am
writing
you
now,
and
then
let
me
know
your
view.
You
remember
that
we
recently spoke
about
Albert’s and Mama’s
marriage[1]
and
you
said
to
me
that
you
thought
a
marriage
between
Albert
and
me
would be
more
proper.
I
never
thought seriously
about it until
yesterday. Yesterday,
the
question was
suddenly
raised
about
whether
A.
wished
to
marry
Mama
or me.
This
question,
initially
posed
half in
jest,
became within
a
few
minutes
a
serious matter which
must
now
be considered
and
discussed
fully
and
completely.
Albert
himself
is
refusing
to
take
any decision,
he
is prepared
to
marry
either
me
or
Mama.
I
know
that
A. loves
me
very
much, perhaps
more
than
any
other
man ever
will,
he
also
told
me so
himself
yesterday.
On
the
one
hand,
he
might
even
prefer
me
as
his
wife,
since
I
am
young
and he could have children
with
me,
which
naturally
does
not
apply
at all
in Mama’s
case;
but
he
is
far
too
decent and
loves
Mama too
much
ever
to
mention it. You know how
I
stand
with
A. I love
him
very
much;
