I’m
only telling you
this
so
that
you
can
compare your
present standpoint
with
the
one
then.[9]
I
would be
sorry
indeed
if
the
second time
you
did not find
the
happiness you
seek either.
That
is
what
your
friends also
think,
who
are
both
very
noble-minded
and
perspicaciously
prudent.
It
was very misguided
of
Elsa-also
of you-to
want
to
attack
these
persons,
both
of
whose intellects
I esteem
very
highly (each
in his
own
way).[10]
I will
not let
myself
be blindfolded with
open
eyes.
A few
lines from
Mich. just arrived.[11] He
writes: “Write
my poor friend,
whose
suffering
I
understand
well,
that
I
swear
not
to do
anything
to his
own
detriment.
Tell him
that-whatever he
may say or
do-we’ll
always
be fond of
him.-Poor
pal!
What
does
your
health
have in store for
you?”-
I have
nothing
more
to add.
I
have done
what
I
felt to be
a
friend’s
duty-and
now
I
can
but
keep my peace.
I
hope
that
you are
recovered
soon
and send
my
best
regards.

Highly
esteemed
Colleague,
I
am reading
with
genuine delight
the
correction
proofs
of
your book,
which
I
am
receiving
sheet
by
sheet.[1]
It
is like
a
symphonic masterpiece. Every
word
has its
relation
to
the
whole,
and
the
design
of
the
work
is
grand.
What
a
mag-
nificent
method the
infinitesimal
parallel displacement
of
vectors
is
for
deriving
the
Riemann
tensor![2] How naturally
it
all
comes
out. And
now
you
have
even
given
birth
to
the
child I
absolutely
could not
muster:
the
construction of the
Maxwell
equations
out of
the
guv’s![3]
I
always
thought
that the invariant
_
r
TDik,lm
Jt
-
¿Hk,
Im-ti
(Rik,lm)
= (ik.lm)
would have to
generate
this.
But
I
could not
manage
to do it.
Naturally,
I
am
tremendously eager
to
see
you
and
your
paper.[4]
I
speak
for
myself
in
hoping
that
you
will
visit
me
at
the end of
March;
I
still
can
hardly
ever go
out,
after
having
been
resting
for almost
a
quarter of
a year.[5]
Sending you
my
warm
greetings, yours,
Einstein
