Actually, doing science is moral, and so is farming. Both are helping you to live a better life, which is the essence of morality.

So I agree with you that the author is totally wrong, just for different reasons.

Plenty of science exists with questionable morals. E.g. military science

If I had said, "Cars are used for transportation," would you say, "I know a guy whose car doesn't have a motor, but he sleeps in it"?

Or if I had said, "Tables are flat surfaces," would you say, "I saw a table in the museum of modern art that had a curving surface"?

So, yes, you are completely right, and I don't dispute what you're saying, but it does not invalidate the generalization. Analogously to the example cases I just gave.

There is probably some philosophical name for and explanation of this phenomenon, but I don't know what it is.
