Careful

When
he
was
younger,
he
thought
science
would
make
good
things
for
everybody.
During
the
war
he
doubted
that
some
evil
may
be
involved
in
science.
Later
he
thought
long
about
the
value
of
science
and
finally
tried
to
answer
this
in
this
talk.

Writing
Possible
answer:
When
Richard
Feynman
was
young,
he
thought
the
only
use
for
science
was
to
make
good
things
for
people.
However,
after
he
worked
on
the
atomic
bomb,
he
realized
that
science
could
also
be
used
for
evil.
He
wondered
what
the
value
of
science
really
was
and
he
decided
on
three
values.
The
first
value
is
that
scientific
knowledge
enables
us
to
do
and
make
all
kinds
of
things.
The
second
is
the
intellectual
enjoyment
it
can
provide
us
with.
And
the
third
value
is
scientists
freedom
to
doubt.
Observe
the
verbs
in
different
situations
Put
another
way,
what
is
the
value
of
the
science
I
had
long
devoted
myself
to-the
thing
I
had
loved
-
when
I
saw
what
terrible
thing
it
could
do?(line
6-7)
Of
course
,
if
we
make
good
things
,it
is
not
only
to
the
credit
of
science;it
is
also
to
the
credit
of
moral
choice
which
led
us
to
good
work.(line11-13)
Such
power
has
obvious
value-even
though
the
power
may
be
negated
by
what
one
does
with
it.(line14-15)
Never
concerned
that
the
answer
may
let
us
down,
with
pleasure
and
confidence
we
turn
over
each
new
stone
to
find
unimagined
strangeness
leading
on
to
more
wonderful
questions
and
myteries.(line20-22)
But
our
freedom
to
doubt
was
born
out
of
a
deep
and
strong
struggle
against
authority
in
the
early
days
of
science(line31-33)
It
is
our
responsibility
as
scientists,
knowing
the
great
progress
that
is
the
fruit
of
freedom
of
thought,
to
declare
the
value
of
this
freedom;
to
teach
how
doubt
is
not
to
be
feared
but
to
be
welcomed
and
discussed,
and
to
demand
this
freedom
as
our
duty
to
all
coming
generations(line37-40)

换句话说，
当我看到它能做的多么可怕的事情时，我长久以来为之奉献的---我曾经钟爱的----科学的价值是什么？
当然，如果我们做了善事，
不仅归功于科学，还归功于引导我们行善的道德选择。

但是我们怀疑的自由权是在科学早期的一场与权威的深刻而激烈的斗争中诞生的。
我们明白巨大进步源于思想自由，作为科学家我们有责任声明这一自由的价值，有责任教育人们不必害怕疑惑而要欢迎疑惑讨论疑惑，有责任强烈要求这一自由，这是我们对后世的义务。
