Arguments for God in Quran.

[Edwardo Piet]

In your case, if everyone agreed that magic exists, I would say premise 2 and 3 are obvious.

Everyone agrees on guidance except real obtuse.

What people agree on is irrelevant to your argument.

I can equally say that everyone disagrees on the existence of this 'guidance' thing, except for the obtuse people.

See, if all you're gonna do is attempt to reinforce your own argument with bare assertions about "anyone who disagrees is obtuse", then I can do the same.

It's statements like this that really get in the way of your arguments. If every time your argument gets questioned you just say that people who disagree with your premises are being obtuse, it's not going to work.

Premises are SUPPOSED to be questioned, that's what being rational is all about. Premises should be conclusions that have been reasoned to from other premises. Otherwise you could start from any old absurd premise and argue to absurd conclusions.

Your argument is only as good as your premises, so they ought to be conclusions from further premises and eventually the premise behind it all should be very sound. If you can do that, you've succeeded, provided you still keep a valid structure.

You've got the hang of the valid structure thing, or at least sometimes you have, you're demonstrated your ability to make a valid argument. All you need to do now is stop giving up when people question your premises. Soundness is a necessity.
