The voice had genuine concern, whatever that meant. She tried to answer but the attempt induced a fit of coughing: the remnants of the river she had inhaled barking and spluttering from her mouth. Gradually the coughing subsided.
"Yeah, I think so."
There was a long pause, then he spoke again. Tentatively.
"If I might say, that seemed deliberate."
"Well I was watching and that definitely wasn't a fall. You jumped right in there."
She looked at her rescuer. Hair plastered to his face. Clothes shining wet in the moonlight.
"No it wasn't. An accident, I mean. My intention was to kill myself."
"Well I'd say it was a good job that I was here. But you might not think so."
Her attempt to reply was drowned in more coughing.
"I mean, you might ask what right I have to prevent someone from carrying out an action that they clearly intended. An act that, one might say, was of their own free will."
She looked at him sharply. Did he know? But his face was impassive and gave no indication of any deeper knowledge of her predicament.
"Fuck that." She replied. A dry cough serving to underscore the final word.
"You think I have that right?"
"No. I don't think anyone has any rights at all. Or at least if they do, it doesn't make any difference. The "that" I was fucking was free will. It was free will -- or rather the absence of it -- that led me here in the first place. That drove me to try to take my own life."
His subsequent exhalation metamorphosed into a laugh. This annoyed her. There was something stage-managed about it, almost commedia dell'arte. A laugh invoked by the recognition of something that an unseen audience had yet to find out. The exaggerated thigh-slapping laugh an English Literature teacher does in front of his pupils on hearing a Shakespearean joke. Seemingly recognising her irritation he spoke ahead of her retort.
"I'm sorry. I didn't mean to laugh. It would be odd enough to say that you were compelled to do something because of free will. It seems even odder to say that you were compelled to do something because of the absence of free will. Or, thinking about it further, maybe the absence of free will just leaves one perpetually compelled. For if there is no freedom, what else remains but compulsion?"
"I wonder." She said. "Whether it is traditional for people to have this kind of conversation when one of them saves the other from drowning. It could be the case, I suppose, I guess such conversations are rarely recorded for posterity."
He laughed again, this time more naturally.
"I imagine closeness to death seldom inspires immediate philosophising. A friend of mine was involved in a near-fatal car accident and he told me that far from his life flashing before his eyes all he could think about was whether he had put the bins out."
It was her turn to laugh, but he continued.
"Philosophy is seldom best done when ones mind is doused in adrenaline -- if I may be so bold and mix ontologies in such a way -- a cup of tea and an armchair, yes, drowning, definitely not."
She looked at him more closely now. He'd scooped his sodden hair back off his face. It was an everyday kind of face, a face that does the job of presenting its owner to the world without presumption, a face that makes no specific claims about the person beneath. By the two pink depressions on either side of the bridge of his nose he had also lost his glasses.
"Well you're certainly managing to sound like a philosopher, bins or no bins."
"I dabble. Although I would hate to call myself 'a philosopher'. It is a bit like calling oneself a poet or a comedian no sooner has the word passed your lips than its 'ooh give me a rhyming couplet then, crack me a joke, explain Nietzsche's concept of eternal recurrence'. And of course, in such situations one's mind quite dries up. Although, I guess that might be useful right now."
He blew a drip of water theatrically off his nose.
This time they both laughed.
She shivered which brought her mind back to the reason why she was here.
"Strange that of all the people who would rescue me it should be a philosopher. Or at least someone who dabbles, or should that be paddles?"
The expected laugh did not come. She turned to face him, for the first time there was an intense, almost grim, look upon his face. He was staring right at her.
"Miss Bailey, I'm afraid I'm here to rescue you twice."

If we live in a deterministic universe then free will is impossible, if we live in an indeterministic universe then free will is impossible.
A deterministic universe means that so long as you know the particular starting conditions of the universe AND you know all the laws of physics then you can predict all future events (this is an 'in principle' argument, as you might have realised). So a sufficiently intelligent and knowledgeable individual could predict knowing the conditions after the Big Bang all future events, including the formation of the solar system, the evolution of life and -- because our minds are just made of stuff -- your response to this sentence (the French mathematician Pierre-Simon Laplace imagined a daemon that could do this).
This means that all your actions could have been predicted billions of years ago. There is exactly one possible future (as Dennett puts it), so no free will.
On the other hand if the universe is indeterministic then this means that there is an element of randomness. Sometimes a particle goes this way, sometimes that way. Which means that your decisions might also contain and element of randomness -- a coin flip. The reason why you decided to read this post might have just been the result of some random event inside your head. Your actions are -- at least partly 'determined' by indeterminate randomness. Again, doesn't feel like free will to me.
Many people get depressed by this, but you really shouldn't. The source of most people's depression is the feeling that what they do 'doesn't matter'. "If everything is determined" they say "then it doesn't matter what I do." Or "This means that I have no control over anything".
Both of these positions are, I believe, false. The problem is that bloody word 'I' (or 'me' in some cases).
If you are talking about some kind of ghostly 'I' (or 'me') that is somehow outside the physical world then this is true, but if you think of 'I' as meaning 'The set of biological/cognitive processes that constitute what I am as a human' then you very much do matter and you DO have a choice. Take the decision to save a drowning child (I assume you would do this because I assume you are nice people). You might say that that is not a free decision because someone (Laplace's Daemon) could have predicted your choice a billions years ago. But the fact is that YOU with all you particular genetic quirks and life experience had to be exactly how you are in order to make that choice. That simple decision is a the result of a cascade of neuronal/cognitive processes drawing on information from inside (your emotional response -- sympathy, empathy) and outside (that the rescue is possible, for example).
In Frank Capra's 'It's a Wonderful Life' the protagonist gets to see the world as it would be if he had never lived. He sees misery and corruption, a dead brother that he was never around to save, an 'old maid' that he was never able to marry, etc., etc. The central message is that he mattered, he made a difference because the world would have been different had he not been born.
It is the same with free will. You genuinely did make that decision to save that drowning child, to join that gym to give up smoking. No one or thing make that decision for you. If the universe were deterministic that decision could -- in principle -- have been predicted but you were the one that chose to do it.
The reason for the confusion and nihilism is that people ask the wrong question they ask 'do I have free will', To this I think the answer is no. Free will is not something that you 'have' like a cocktail shaker or a cocker spaniel. Having something means that you can do something with it. If you want to preserve the term 'free will' then think of it as something that you are.
As a coda I must address a final point of nihilism which is when people respond to the above by saying 'OK OK I get all that but it still means that it is impossible to change the future'. WTF does that even mean? Of course you can't change the future because it hasn't happened yet and once it has happened it's the past (and you can't change that either!)

The belief seems to be that students will demand more teaching for their money.
But is this right?
It is sometimes said that no-one wants a drill, they want a hole. Similarly students don't want teaching they want knowledge, skills and, ultimately, a qualification; teaching is a means to an end, not an end in itself.
Being on the receiving end of teaching -- despite our best efforts -- doesn't always top of students' list of Things That Constitute a Fun-Packed Day. When my colleagues express surprise that students don't turn up for additional teaching I suggest they might find an answer if they replace the word "teaching" with "all over body waxing" or "rectal examination" which are also not ends in themselves.
Like all over body waxing, cosmetic surgery and dieting teaching is a necessary evil to achieve the end of positive change and it is this that we "sell". The creepy Dr. Christian Jessen presenter of Supersize versus Superskinny and the frankly bizarre Gok Wan presenter of I Like Fat Ladies know that people will endure all manner of humiliations and agonies if they can present them with a positive"before" and "after" picture at the end of the programme.
Before and after pictures are difficult in HE, not least because of Red Queen effect "It takes all the running you can do, to keep in the same place". Students just manage to acquire one set of skills/knowledge and we shift the assessment goal posts assessment in order us to ensure they have developed the next set. Although this is standard practice, it is hard to think of a more demotivating system: all that time, all that effort to go nowhere.
If we are to justify our extortionate fees to students and their parents we need to make it clearer that we are agents of positive change and we need to provide concrete evidence of this. Don't stress over the contact hours, look what you've become.

"Curious? Of course it's curious that's how we managed to secure the funding; if it wasn't curious there'd be no point in doing the research in the first place. Listen, we have only one more year of funding and I, for one, do not think that the research council will be pleased if after three years our final report says that 'its curious'. Nor will they be overly impressed if all we can stump up is another bloody tapeworm. What is it about you and tapeworms anyway?"
"This isn't a tapeworm, professor, this is far bigger and its life cycle is ... well interesting."
"Precisely professor, the host does all the donkey work in finding food and digesting it. The parasite just steals it. The ultimate ready meal, I suppose. Anyway it quite quickly reaches quite a size."
"Very. By the end the sufferer’s body is distended so much that they find it difficult to walk easily."
"But Qua-Kon we know that parasites are creatures of stealth. They operate by subverting their host's biological processes and using them to their own ends, so conspicuous a parasite would surely get killed as soon as it emerged."
"And it if were killed it would be unable to divide..."
"So if it can't reproduce how does such a parasite continue to survive? This is against every biological law. I'll never be able to publish this. I'll be a laughing stock! We'll all be a laughing stock!"
"Ah but that's the really, really clever part. It doesn't get killed."
"Well as I said earlier, it takes control of the hosts mental processes. Look you'd imagine, would you not, that if a great, blood-spattered parasite tore its way of your abdomen you'd look around for the nearest coal shovel and batter the life out it if."
"Certainly, I would."
"But they don't. They wrap it in a blanket and cuddle it.”
"This is all too much Qua-Kon."
"I've not even got my pants off yet, if you pardon the expression, professor. So great are its powers of manipulation that it continues to parasitise the host, or I should say hosts -- you know how these earthling tend to inexplicably hang around in pairs? Well it parasitises them for years."
"Years, professor. The hosts spend many thousands of their earth pounds providing the parasite with all it needs -- food, drink, even small artefacts that the parasite seems to derive some sort of pleasure from. Although we currently have no conception of what biological purpose these artefacts play in the parasite's life cycle."
"From what you say, Qua-Kon, this sounds more like a symbiotic relationship. Mind control or not, no rational organism would surely devote so much time and effort satisfying the desires of such a parasite. There must be something that the parasite -- or symbiont as I would prefer to think of it -- gives back to the host. I simply refuse to believe that such a degree of psychological manipulation is possible."
"I know professor. The thought had occurred to us too. But our scientists report that the parasite provides nothing to the hosts. Not only that, but if the hosts aren't supplying enough food, or enough drink, or enough of these apparently functionless artifacts the parasite makes these noises."
"Noises? What kind of noises?"
"Oh horrible, blood-curdling noises. Screams the like of which you've never heard. They also throw themselves on the floor flailing their limbs so much that we initially thought it was experiencing some kind of seizure."
"And then what?"
"Oh the hosts are soon off getting food, or drink or artefacts which seems to placate the parasite temporarily. I tell you professor some of our scientists have themselves taken to obtaining a selection of small artefacts just in case the hosts fail to stump up the goods. That's how nerve-janglingly awful the whole thing is."
"And for how many years does this last?"
"We're not exactly sure, but we get the feeling it may well last for the host's lifetime."
"A lifetime! Hell's teeth I thought that those parasitic wasps we discovered were bad, but this is immeasurably worse. How do they believe their god could permit such a thing?"

I'm generally wary of the word addiction. It seems too easy to label any behaviour performed to excess as an addiction. In the old days addiction was used to refer exclusively to the misuse of pharmaceutical products (alcohol, drugs) that exert their effects by way of a direct tinkering with neurochemistry. Further, it seems that the word addiction can be used as a means to exculpate the individual from personal responsibility. We hear of sex addiction, shopping addiction and gambling addiction -- the old-style response would have been "pull yourself together and take control of your life". Nowadays such people are looked upon sympathetically and described as having 'a disease'.
But hang on. If we accept pharmaceutical addiction as real should we not accept behavioural addictions as real also? After all they affect the same reward systems and neurochemical pathways as do drugs; they just do it indirectly rather than directly. Cocaine and, say, sex have similar effects on the neurotransmitter dopamine, so it seems churlish to refer to a craving for the former as an addiction and the latter as not.
But what about Facebook addiction? Is it possible to describe excessive use of Facebook as an addiction? The fact is that many so-called "internet addictions" are misnamed. People aren't really addicted to the internet per se (the internet is just a bunch of cables, routers and protocols, after all) what they are addicted to are online services. So people with "internet addictions" have addictions to online gambling, pornography, shopping and the like.
So a Facebook addiction is probably a social addiction but the notion of a social addiction still seems odd. You might well consider someone who morbidly browses eBay for hours on end a shopping addict, but is it possible to be a social addict?
Consider a person who spends 5 hours of their day chatting to friends face to face or on the phone, is that person a social addict? What about someone who spends 10 hours doing it? We probably all know people who find it difficult to spend time on their own, who find that they always have to be engaging in social interaction with others, however trivial. Although these people can be irritating -- especially when you have work to be getting on with -- we would probably never think of them as being social addicts.
Interestingly if you look at the synonyms for "sociable"
accessible, affable, approachable, close, clubby, companionable, conversable, convivial, cordial, familiar, genial, good-natured, gregarious, intimate, neighborly, regular, social, warm.
All positive, things you want to be.
And here are the antonyms.
introverted, snobbish, unfriendly, unkind, unsociable
My point is that our language enshrines our view on sociability, it is seen as a good thing to be sociable and a bad thing to be unsociable. Is there even a word that means "excessively sociable"? Is there such a thing as an "excessive social personality". A few minutes on the internet suggested not. All I found were webpages on William's syndrome a chromosomal disorder that, among other things, leads individuals to excessive sociability. This is seldom seen as a problem apart from the fact that their generally low IQ can lead to them being overly trusting and ripe for exploitation.
So there is no such thing as social addiction (at least not yet) and there are no words to describe personalities that crave the interaction of others. But interact with other people through a computer and hey presto you have a "social media addiction" or a "Facebook addiction" (Google them).
Here is the way I think of it. Salt, fat and sugar are essential for life but were rare in our ancestral environment so we developed a strong preference for their flavour to ensure that when we got them we ate as much as we could. This strong preference is now problematical as the industrial manufacture of foods makes them plentiful. We repeatedly gorge ourselves on each cheeseburger as if it were the last with the result that we become fat. Likewise as social species we evolved an obsession with the lives of others we need to know where we are in the pecking order, who's doing what to (and with) whom, who's in, who's out, who's up and who's down. Facebook presents us with all of this stuff on one easily digestible site so we gorge ourselves. But what are the negatives?
Hard to say. Aric Sigman thinks using Facebook will lead to poor mental and physical health ("Facebook gives you cancer" the headlines screamed) and there are plenty of others out there who will reach for their apparently endless supply of non sequiturs and present poorly constructed hypotheses as fact (but enough about Susan Greenfield).
Many of these arguments rest on the premise that people are neglecting their "real" (by which they invariably mean face-to-face) friends preferring to chat with their online friends (who, if you read the Daily Express, are a collection of men pretending to be women, paedophiles, stalkers, identity thieves, spammers and psychopaths). But most online friends are offline friends so most aren't neglecting these relationships and there is no evidence that use of Facebook leads to a decrease in face to face activity.
If Facebook addiction truly an addiction with no consequence? The fag that doesn't give you cancer, the booze that doesn't bloat your liver, the cheeseburger that doesn't make you fat?
