There's really quite a bit to take away from this interview. The first thing that stands out to me is this:
It seems to me a fundamental dishonesty and a fundamental treachery to intellectual integrity to hold a belief because you think it's useful and not because you think it's true.
Later, the interviewer asks him if the so-called "ordinary people" might not be strong enough to find their own "personal ethic".
To paraphrase, Russell responds with "Bullshit."
