Michael Bycroft published an essay on the thorny question of the concept of biological race, in the French magazine Books. Here is a translated abstract:

"We are told that race is a social construct. But the biological dimension of race is nevertheless hard to deny. A historian of science delves into the maze of claims and counter-claims on this topic. He reaches a surprising conclusion: what if the real problem is not the idea of biological race but the belief that biology can solve our social and intellectual problems?"

The essay is available online, though behind a paywall.
