③ Scientific knowledge is an enabling power to do either good or bad—but it does not carry instructions on how to apply it.
① The first way in which science is of value is familiar to everyone: scientific knowledge enables us to do and make all kinds of things.
② Of course, if we make good things, it is not only to the credit of science; it is also to the credit of the moral choice which led us to good work.
④ Such power has obvious value—even though the power may be negated by what one does with it.

Appreciative reading
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.

Summary writing
One possible version:
Despite the deep love and devotion to science, the destructive results of science caused the author to think twice about the lingering question after the war—what’s the value of science
The first value in his view is its powerful creation, good or bad, depending on how we use them. Intellectual enjoyment, the second value, lasts during the process of exploring and discovering mysteries based on scientific knowledge we are equipped with. Freedom to doubt, the greatest value, was won through cruel struggle by brave pioneers. Consequently, it’s our responsibility to defend, advocate and pass it down to the following generations.
