9. Are space and time just constructions of our mind? Yes: 4 No: 8 Not Sure: 2

Fortunately, there is a fair amount of apparent disagreement in the responses. I say “apparent” because several of the questions seem unclear; perhaps if we figured out exactly what they are asking we would not disagree as much. (Hopefully we would still disagree a fair amount, however.) A good way to begin blog discussion is to either:

(i) Post a defense of your answer to one or more of the questions,
(ii) Present an argument in numbered premise-conclusion form in support of your answer to one or more of the questions, or
(iii) Post on what, exactly, you take one or more of the questions to be asking. (Some initial questions: What the heck is a parallel world? What, exactly, is meant by ‘dimension’ or ‘universe’? What would it mean for time to have a beginning? Does it mean that there was no time at any instant prior to the instant that time began?!?)
