You are quite free to do so, unless you pick the definition of law which is exclusively legal, which is the abuse of language that this argument depends on. If you choose a definition of law under which natural laws or mathematical laws can be counted, then the first premise is indeed false (in a materialist framework anyway).
When you change the definition of law to the legal one, the second premise becomes nonsense.
Regardless of which you pick, any reasoned inference which respects the language involved will generally lead to one premise being true and the other false. Essentially, a materialist can arbitrarily decide which is the true premise and which is the false premise (provided a particular definition has not been made clear beforehand).
I don't know if there is a common definition of law which could make both premises false.
Besides, I didn't mention this because it was a good argument. I mentioned it because it is a shockingly bad argument that I have seen people take seriously.
Sorry I was unclear... I meant my comment literally. I've never heard anyone making this argument, and I'm curious as to what happens if, in response, one says "Not all laws are constructed by some intelligence." That is, how do the people making this argument respond?
Edit: yeah, what danfly said.
What's the worst argument you can think of?
One of my favorites is from a Theodore Sturgeon science fiction story in which it's claimed that faster than light communication must be possible because even though stars are light years apart, a person can look from one to another in a moment.
I don't know about you, but bad logic makes my stomach hurt, especially on first exposure.
This seems rather odd-- what sort of physical connection might that be?
Also, I'm not sure how common the experience is, though a philosophy professor did confirm it for himself and (by observation) his classes. He mentioned one of the Socratic dialogues (sorry, I can't remember which one) which is a compendium of bad arguments and which seemed to have that effect on his classes.
So, how did you feel when you read that bit of sf hand-waving? If your stomach hurt, what sort of stomach pain was it? Like nausea? Like being hit? Something else? If you had some other sensory reaction, can you describe it?
For me, the sensation is some sort of internal twinge which isn't like nausea.
Anyway, both for examination and for the fun of it, please supply more bad arguments.
I think there are sensory correlates for what is perceived to be good logic (unfortunately, they don't tell you whether an argument is really sound)-- kinesthesia which has to do with solidity, certainty, and at least in my case, a feeling that all the corners are pinned down.
Addendum: It looks as though I was generalizing from one example. If you have a fast reaction to bad arguments and it isn't kinesthetic, what is it?
