Is the following transcript between Richard Dawkins and Justin Brierley genuine?
Justin Brierley: When you make a value judgement don't you immediately step yourself outside of this evolutionary process and say that the reason this is good is that it's good. And you don't have any way to stand on that statement.
Richard Dawkins: My value judgement itself could come from my evolutionary past.
Justin Brierley: So therefore it's just as random in a sense as any product of evolution.
Richard Dawkins: You could say that, it doesn't in any case, nothing about it makes it more probable that there is anything supernatural.
Justin Brierley: Ultimately, your belief that rape is wrong is as arbitrary as the fact that we've evolved five fingers rather than six.
Richard Dawkins: You could say that, yeah.
I haven't read or watched an awful lot of Dawkins' work, but it seems a little out of character for him. I would have expected him to talk more about the ability of humans to engage in rational thought.
I tried googling for mentions of this discussion, but I could only find Christians mentioning it, rather than atheists or neutral sources mentioning it.
Is the above transcript accurate (or largely accurate), or is it fake or misleadingly edited?
