The
____________________
of
____________________
is
____________________
very
____________________
.
There
is
his
____________________
evolution
,
all
the
____________________
that
____________________
us
from
ape
____________________
.
That
____________________
some
____________________
of
____________________
.
And
then
there
is
his
____________________
history
.
All
that
[
separates
]
us
from
the
few
surviving
____________________
tribes
of
____________________
,
or
food
____________________
of
____________________
;
and
all
that
huge
____________________
gap
is
in
fact
____________________
into
a
few
____________________
years
.
It's
____________________
to
think
,
that
only
in
the
last
12
,
000
____________________
,
has
civilization
as
we
____________________
it
,
taken
____________________
.
There
must
have
been
an
____________________
explosion
in
____________________
,
000
BC
,
and
that
was
a
____________________
explosion
.
It
was
the
____________________
of
the
____________________
____________________
Age
.
This
is
____________________
in
____________________
which
____________________
itself
every
____________________
,
but
which
____________________
itself
____________________
over
____________________
and
____________________
when
the
ice
____________________
?
.
And
____________________
,
who
had
come
through
these
____________________
____________________
,
and
marched
up
from
____________________
over
the
last
____________________
years
and
____________________
through
____________________
ice
____________________
,
suddenly
found
____________________
flowering
,
the
____________________
surrounding
him
.
And
____________________
into
a
____________________
kind
of
____________________
.
It's
usually
called
the
____________________
Revolution
;
but
I
think
of
it
as
____________________
much
____________________
,
the
____________________
Revolution
.
.
.
There
was
____________________
in
it
the
____________________
of
____________________
and
the
____________________
of
____________________
in
a
kind
of
____________________
.
And
under
this
ran
the
crucial
____________________
that
man
makes
his
____________________
,
not
____________________
,
but
at
the
level
of
living
____________________
.
And
____________________
.
With
that
,
there
comes
an
equally
____________________
____________________
____________________
.
Because
now
it
became
____________________
-
more
than
that
,
it
became
____________________
-
for
man
to
____________________
.
And
this
____________________
that
had
____________________
and
____________________
for
a
million
____________________
had
to
make
the
crucial
____________________
whether
he
would
____________________
to
be
____________________
,
and
become
a
____________________
.
