I'm not sure many would take a debate as the whole story of truth - but at the very least, it gets people thinking and open to the idea that a particular position may have more to it than was once thought.
when such a charged issue is being debated, and when character such as william lane craig participate, i am generally quite skeptical about the capacity of the debate format to promote free thought.
If a debate encourages further research, investigation and general truth seeking, then I view it in a pretty positive light.
this is a post-hoc justification of the oratory tactics of both parties, and obviously begs the question.
Personally I'm not too concerned that there are time limits on replies etc. That's a two edge sword that works against both participants and has to be there for the practicality of a time limit on a debate as a whole. Besides, both participants are likely to have their own body of written works which would flesh out the finer details of their positions anyway
no, this is patently false. i suspect that, because of your own biases, you are compelled to rationalise the flaws of the debate format, but i don't need to attack your character to make my point.
yes the time limits have to be there, but if you actually read what I or garygaz said, the debate format (including these time limits) is often stacked in the favour of one party, such as craig, who can exploit the format to impose unrealistic burdens on their opponents. craig, for instance, inserts a large number of assumptions, misrepresentations and ambiguities into his arguments. there are various reasons craig can get away with this, mostly because many of his tactics, such as assuming that god exists, equivocating between 'god' and 'the abrahamic god', are rendered relatively innocuous due to the cultural and philosophical context of this debate. mounting a defence against these tactics is an immense task, and is often pointless considering that you cannot rebut every argument or address every assumption, and the ones not rebutted will be claimed to be conceded. on top of this, if you do so, craig will accuse you of diverting the discussion and not addressing the question.
your final point, that participants have their own body of written works, is only half true. the benefit of debates is that they are accessible, and demand far less mental effort and cogitation than reading a book and really scrutinising an author's argument. if the debate was an impartial and honest means of exposing an audience to the philosophy and works of either participant, you might be right. but it's no surprise that william lane craig is far less impressive in paper than he is in person.
