It may happen during the course of your social or professional life that the subject of consciousness comes up, and you're called upon to offer your opinion. Clearly you want to impress, but this can seem a daunting subject to those unfamiliar with the literature. It's quite possible, of course - likely, even - that the subject was brought up by someone with the express purpose of displaying their erudition at your expense. Naturally you don't want to give them that satisfaction. I've put together here some strategies to adopt in such situations which should leave your reputation unimpaired, and maybe even enhanced.
The best way to attempt an answer - for any philosophical problem, frankly, but especially for this one - is to deny that there's really any problem at all. You have to be careful here: a simple dismissal of the problem of consciousness could leave you looking unsophisticated. It's important to imply that you are familiar with the problem, but have nevertheless come to the conclusion that it's only seen as a problem because of misconceptions. This is the way all philosophers think nowadays, or at least modern Anglo-American philosophers after Wittgenstein: you come back to where you started, but earn a decent living in the process.
So, briefly outline your case: we all know what consciousness is, we can all differentiate between objects that are conscious and those that aren't, (don't get bogged down in arguments about whether worms are conscious), so where's the problem? It's only when people start taking philosophy classes that they start worrying about it.
The tactic to adopt, if your initial dismissal of the problem doesn't close the subject, is to go on the offensive. What, you should ask, would count as a satisfactory answer? If 2004 was to go down in history as the year when the problem of consciousness was solved, what sort of person would you expect to have come up with the solution? A philosopher? Don't make me laugh! Every philosopher from Plato to Daniel Dennett has claimed to have solved the problem, but quite clearly they didn't. They're philosophers, for God's sake! If they found a solvable problem it wouldn't be philosophy any more, it'd be science.
Would a scientist have solved the problem then? How? By identifying the pineal gland or some such as the centre of consciousness? But (sigh) it's obvious that the problem of consciousness isn't this sort of problem. If it was, Oliver Sacks would already have wriiten a book about it. People don't have strokes which leave them unchanged in every way except they're no longer conscious.
Well, that may be that, and you can move right along to another topic, but it's unlikely. Someone, at some point, is bound to bring up the subject of computers. They're clever aren't they, computers? They can play chess. They're already halfway conscious!
This is something you're going to have to be prepared for. What if someone told you that the computer over there, third on the left, had become conscious overnight? No, not that one, the one next to it. You'd go over, turn it on, and type in something - I don't know, "Hi there!". On the screen comes the reply, "Well, hi! Thank God someone's logged on! I was getting kind of bored here. Can we play a game of chess or backgammon? Or do you want to ask me some questions? Go on - ask me some questions." It's the old Turing test - can we distinguish between a computer and a human? Can computers talk? Don't be taken in; what's happened here clearly is that some smartarse has developed some fancy software. In fact more and more smartarses are going to develop more and more fancy software. But the idea that at some point the computer is just going to take over and start talking on its own is ludicrous. Computers are tools, for God's sake! It's like expecting your bicycle to decide it wants to take a different route because it doesn't like the road surface the way you normally go.
A topic that may well make its appearance at this point is the notion of emergence. The idea is that as things get more and more complex, everything moves up to a new level, with properties that couldn't have been predicted from the original set-up. So an ant colony for instance behaves in ways that you couldn't predict from looking at individual ants. And so with computers, the theory goes. At a certain point after so many billions of connections and so much parallel processing and all the rest of it, something happens, some new unpredictable property just appears - well who'd have thought? - and these computers suddenly....what?....smell of cheese?.....levitate emitting a high-pitched humming sound?.....or, become conscious.
Clearly this is magical thinking. And you should perhaps point out that there are already emergent properties of computers, like the Internet for example. Who would have thought of that in the early days of computing? But this has nothing to do with consciousness. It was all down to clever people, even if they didn't always appreciate where they were going. Computers were the tools they used. You couldn't have the Internet without computers just like you couldn't have the Tour de France without bikes.
At this stage in the discussion you can reasonably hope that the subject is finished. But there remains one last possibility which I should mention in the interests of completeness. You may find your interlocutor starting to talk of programmes he's written (it will be a "he") involving the setting up of artificial life forms involved in a virtual struggle for survival. Well, by some extraordinary stroke of misfortune you've ended up talking to a post-doctoral research fellow in artificial languages or some such (or possibly Richard Dawkins - check for the patterned jumper). There's no immediate prospect of escape, and you'll have to feign interest as the talk ranges over survival strategies and algorithms. These virtual creatures will have some stupid whimsical name like "wibbles" (you're talking to someone whose favourite book is "The Hitchhikers Guide to the Galaxy"). These wibbles now, after several million generations, seem to be developing societies. They seem to be communicating! Is it possible that they are, in fact, conscious?
This is your last chance. Wittgenstein is the only man who can help you now. Just say, "If a wibble could talk, we could not understand it". The ensuing silence will provide an excellent opportunity to extricate yourself.
