“I can live with doubt, and uncertainty, and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers, and possible beliefs, and different degrees of certainty about different things, but I'm not absolutely sure of anything. There are many things I don't know anything about, such as whether it means anything to ask "Why are we here?"”
I might think about it a little bit, and if I can't figure it out then I go on to something else. But I don't have to know an answer. I don't feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose — which is the way it really is, as far as I can tell. Possibly. It doesn't frighten me.

Post-interview on-camera remarks, requesting they not air his interviewer's attempt to ask him about comedian Hannibal Buress' comedy routine about multiple women having alleged that Cosby drugged and raped them:
Brett Zongker: I have to ask about your name coming up in the news recently regarding this comedian—
Bill Cosby: No, no, we don't answer that.
Brett Zongker: OK. I just wanted to ask you if you wanted to respond about whether any of that was true.
Bill Cosby: There's no response.
Brett Zongker: I'm gonna ask you, if— With the persona that people know about Bill Cosby, should they believe anything differently about what—?
Bill Cosby: There is no comment about that.
Brett Zongker: OK.
Bill Cosby: And I'll tell you why.
