Terms of Estrangement (Shreeve)

This article is kind of anthology which includes various opinions by many scholars.
However, the author's opinion should be expressed by the last quotation by Peter Smouse.

The main issue argued in this is "Is the 'race' can be used in scientific worlds?."
Shreeve is introducing many cases and opinions to question what the race is,
and his answer to it is clear.
He indicates that the traditional criteria of race are not biological, but cultural,
so they can be changed easily and it depends on people's perception.
Therefore, the concept of race cannot be used in science, he says through Smouse's words.
I partially agree with that. Actually, the traditional "race" which divides people by appearance can not be an useful grouping for science and at the same time, it has created historical tragedies and discrimination.
However, I feel that humans can not stop separating each other. Scientific data cannot be obtained without grouping or generalizing the research object at first place.
So, the word "race" should not be used in science because it sounds racist often and the criteria are not established, but scientists can create the one-time group whose criteria are convenient for their research. For example, divide people into high-body-temperature group and lower group to study something about health. But those grouping can never be used for social activities. It is the most difficult point.
