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.

How to write a summary
We analyze the structure of the passage and find out the ways that the writer shows his/her ideas. Tick out the main points to make up your summary with concise words.
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.
