This is the context:
What Jim is saying is we may have all sorts of scientific accounts that involve something preceding the Big Bang, or that the Big Bang occurred, as Jim was saying, in some larger arena, or something like that. What none of this seems directed at eventually bearing on, and what I don’t see how it could eventually be directed at bearing on, are questions like the one Jim was alluding to a minute ago, e.g., why there’s something rather than nothing, or how it is that something that’s in some genuinely, philosophically interesting sense nothing produces something?
What is the meaning of the bold parts? I searched the dictionary but couldn't find a meaningful meaning? Can anyone help?
