The debate concerning God's existence, like many debates in philosophy – the success of sceptical arguments, the nature of time, the moral permissibility of war and scores of examples like them – is a matter on which the best philosophical minds disagree. Partisans of both sides can be found who present and defend their arguments with rigour and sophistication, find these arguments compelling and at the same time seem to have a clear understanding of their opponents' views. From this we can, I think, derive several lessons. One obvious lesson is that this debate, like most debates in philosophy (indeed, like many debates in academia) is one for which we should not soon expect some final philosophical resolution. Nor can we insist that all parties who find themselves in such protracted debates simply suspend judgement, for this would require that most academics jettison many of their intellectual commitments. Besides, the very principle that mandates suspension of belief in the face of disagreement is itself a matter of disagreement, thus hoist on its own petard, as they say.
Second, a small dose of intellectual humility and generosity should help us to appreciate that persons of good mind and sincere will can be found on either side of the debate. This, in turn, should preclude quick dismissals of those with whom we disagree as silly, stupid or in open defiance of the most basic standards of rationality. Respect rather than ridicule for one's interlocutors is the only way forward.
