Loop Station


Thought I would share this video with you. It is a girl called Julia Easterlin, singing on a loop station. Just watch it the whole way through (it gets good in the middle)... hope you like it too.

You tube is one of the most amazing websites ever- I worry to think how much time I have spend on that website. But when you find gems like this one- it makes it worthwhile.

3 mph round the world


Just a short one to put you in touch with a friend of mine (and his newly acquired fiancé) who are "seeking physical and emotional challenges whilst circumnavigating the globe for 21 months" they are "using as many modes of transport as possible, with the exception of flying".

Their stories are very entertaining and the whole project seems fantastic. I hope you enjoy it. Here is the link:

location, location, location?


This is one of the most interesting and, I think, insightful articles I have read regarding the property market. Not being an expert, I wonder what the myriad of friends I have in this sector think about it... comments welcome.

Who would you be?


One of my favourite authors is Malcolm Gladwell. He writes non-fiction; so far primarily within social sciences - psycology and sociology mainly. He has written three books: The Tipping Point (2000), Blink (2005) and Outliers (not out until later this month). He is also a journalist for The New Yorker.

Blink, the only one I have read so far was incredible [postscript: just finished The Tipping Point and Outliers see end of this blog for a brief update]. Gladwell describes the book on his website to be...

"a book about rapid cognition, about the kind of thinking that happens in a blink of an eye. When you meet someone for the first time, or walk into a house you are thinking of buying, or read the first few sentences of a book, your mind takes about two seconds to jump to a series of conclusions. Well, "Blink" is a book about those two seconds, because I think those instant conclusions that we reach are really powerful and really important and, occasionally, really good."

Although the above doesn't give much away, it hopefully provides an idea of the subject material he writes about. Within Blink alone, he draws on numerous fascinating examples to illustrate his ideas- each of which could be a story in themselves. He is very gracious- although a very original thinker himself, he never looks for praise or recognition of this, merely lifts other authors, scientists, artists etc. up on a pedestal and manages to convey just how interesting and incredible their findings are. He has a rare ability to explain complicated ideas and theories to the layman, perhaps only second, in my eyes to Richard Dawkins, who I am sure I will blog about soon.

My motivation for bringing his work up was a recent article he wrote for The New Yorker, entitled "Late Bloomers". If you have 5-10 minutes to spare, click on the link and have a read.

The article investigates society's habit of equating genius with precocity. it is often recalled how Mozart was composing music at the age of five and wrote his "breakthrough" Piano Concerto No.9 in E-flat Major at the
age of twenty-one. Picasso painted Les Demoiselles d’Avignon, at the age of twenty-six (how inspiring yet how depressing), need I say more? He drew upon the work of an economist called David Galenson, who approached this subject scientifically... I will not spoil except to say that his conclusions are very interesting.

Having forwarded the article to a few friends, it sparked up the question: "If you could be any figure in history, who would you be and why?"

What a great question! Although... strictly speaking it is two questions, Cilla Black never realised this so I doubt others will kick up a fuss. It just occured to me... while we are on such a digression- what a brilliant question for Blind Date- I think you could interpret alot from someones answer to this.

I struggled to provide an answer, after all, how can one compare both between generations, often millenia, and between subject fields as varied as philosophy, science, literature, art, sport, etc... after being denied the request to provide multiple answers, each pertaining to a different field in a similar manner to the Nobel prizes, I initially reluctantly and later affirmatively gave my answer... Charles Darwin.

At first sight, perhaps not the most exciting of answers, but lacking a better way to approach the question, I chose to ask myself: what single figure in human history has contributed the most to humanity overall?

He answered one of the greatest questions that will ever be asked of a human being: where did we all come from? With the acquired detachment of four or five generations and with the distortion of hindsight, it is hard to comprehend the
challenge that Darwin faced. In addition, It is also hard to comprehend the breath and depth of his findings- it impacted virtually every area of academia- specifically theology. Without such a discovery I imagine our lives, particularly within politics and leadership would be very different.

so.. that's my answer. who would you be?







postscript: The Tipping Point was, like Blink, very interesting. Unfortunately I found Outliers a bit stale. I recognised the formula used in Blink and The Tipping Point but this time it seemed a touch contrived. It still had moments of intrigue but the overall message was not as interesting as prior books- it essentially tells us that amazingly successful people are borne not from innate natural talent, but the combination of enough talent, good luck and lots and lots of hard work. Good but not great.

Amazing envelopes


I read this great little piece on Harriet Russell in The Telegraph (Horatia Harrod). I copied it below.

As family traditions go, it's unusual. But Harriet Russell is only the latest in her family to seek to amaze and befuddle the men and women of the Royal Mail. Her great-great-great grandfather, Henry Ponsonby, was an eminent Victorian - a veteran of the Crimean War, private secretary to the Queen - who also had a hobby of embellishing the envelopes of the letters he sent with whimsical pictures. The addresses would appear as signposts in snowstorms or as huge envelopes shouldered by tiny people.

Russell's approach was more challenging. Over the course of a year, from her flat in Glasgow, she sent herself 130 envelopes with addresses in the form of anagrams, crosswords, tests for colour blindness, dot-to-dot puzzles, cartoons. The first one she sent was in mirror writing, and when it arrived back at her flat - in the same time it takes for a normal letter to arrive - she knew that somewhere at the Glasgow Mail Centre, someone had enjoyed her work. So she pressed on.

Although she worried about the project at times - 'I thought I might get a letter saying, please stop wasting our time by doing this,' she told me - there were many sustaining little victories. She never met any of her accomplices at the Post Office, but they seemed to be enjoying the game. The crossword she sent out was returned, filled-in, with the proud comment on the back, 'Solved by the Glasgow Mail Centre'. And ultimately only 10 of the letters she sent didn't make it back, among them a particularly testing anagrammatic one, and several that lacked a postcode (the key to getting any letter delivered, she learnt).






















The man who reads dictionaries by Tom Geoghegan

From the BBC news website:

Ammon Shea spent a year reading the Oxford English Dictionary - 20 volumes, 21,730 pages and 59 million words - and he rates poring over a dictionary as enriching as reading a novel. Why?

The prospect of talking to a man who reads dictionaries for fun prompts a sudden vocabulary-insecurity complex and a fear that every word he utters might sound like a painful medical condition.

But thanks to Ammon Shea's belief that long words only hinder conversations, there's no need to consult any dictionaries while he clearly explains his eccentric hobby. "I'm not against big words per se or fancy or obscure words, obviously I love them, but I'm opposed to using them for their own sake," he says. "If words are to form a communication, you use them as a tool to communicate to people and it's pointless to intentionally use a word that no-one else knows."

Mr Shea, a 37-year-old former furniture remover in New York, has spent 12 months conquering what he describes as the Everest of dictionaries, the Oxford English Dictionary (OED), by ploughing through 20 volumes weighing a total of 137lbs.

In the process, he became the Morgan Spurlock of lexicologists, devouring words for eight to 10 hours a day, which caused him severe headaches, deteriorating eyesight and injuries to his back and neck. So why bother? "I've always enjoyed reading dictionaries and they are far more interesting than people give them credit for. And I think everything you find in a great book you would find in a great dictionary, except for the plot.

"All the normal emotions - grief, happiness and loss - exist in a dictionary but not necessarily in the order that you would think." If you come across a word like "remord" (to recall with a touch of regret) it's impossible to read that word without thinking of things that you regret yourself, he says, or to read "unbepissed" (not having been urinated on) without a chuckle.

"Knowing what to call something makes me more aware of that thing. For instance, it's not terribly useful for me to know that [the sound of] leaves rustled by the trees is a psithurism.
"I don't want to walk down the street with my girlfriend saying: 'Listen, there's a psithurism.' But knowing it means I pay more attention to it."


Similarly, knowing that "undisonant" is the adjective to describe the sound of crashing waves and that "apricity" is the warmth of the winter sun brings these things more often to mind.

"It's not easy to use them in conversation and so I enjoy them for their own sake. They are like one-word poems." Turning page after page of unfamiliar words made him sometimes feel like he was reading another language, he says. That was dispiriting but also intriguing, because it showed how rich and powerful the English language is.

But absorbing so much made Mr Shea lose his grasp on his normal vocabulary. He recalls being fascinated when reading the definition for the word "glove" before he realised it was a word he already knew.

"That happened frequently. I guess it gave me a useless large vocabulary and in the short-term I lost my normal vocabulary. I would go to the shop and forget the word for milk. Momentarily I'm looking for the cold, white stuff."

Mr Shea is not alone in his love of dictionaries. WH Auden waxed lyrical about them and Arthur Scargill said his father would read one every day because his life depended on the power to master words.

Thousands of avid Scrabble players read dictionaries looking for words, especially those with a high-scoring J, Q, X or Z, says Elaine Higgleton, editorial director of Collins Dictionaries. And crossword fans devour dictionaries for the same reason.


"We also have people writing to us who have been very interested in obscure words and obscure definitions.

"A student in Iraq was trying to learn English and he sat down trying to learn every word in the dictionary, starting at the beginning with A and working all the way through.
My father still reads the dictionary everyday. He says your life depends on your power to master words


"It's probably not the best way to learn English, and you'd learn many more than you would need."

But dictionaries are a wonderful source of learning about the origins of the English language, she says, and especially the Greek and Latin roots to many of the words. Collins, which records everyday language rather than all known words, is involved in a campaign to save some of the lesser-used words from being edited out of its future editions. Stephen Fry, for instance, has championed "fubsy", which means "short and stout".

"One of the nice things about dipping in and out of a dictionary is that although people are very comfortable with the vocabulary levels they have, there are some good fun words in there that offer an additional dimension of interest," says Ms Higgleton.

Some of Mr Shea's favourites garnered from the OED include "assy", which means behaving like an ass, and natiform, which means "buttock-shaped".

It's impossible to be intimidated by a dictionary that uses a word like assy, he says, and to pick one up and glance through one - rather than just opening one when in trouble with a word - can be a captivating experience.

And how much of what he has read has stayed between his ears? Throwing 10 semi-hard words ( from the OED at him, Shea correctly guessed five definitions. That's a considerably higher success rate than many of us would have scored, after reading 59 million words.

On your head be it...

Okay, so for those of you that have not received Eliot's e-mail, this post concerns the issue of wearing bicycle helmets. I wear a bicycle helmet virtually every time I cycle. Although I have not previously analysed why I do this, off the top of my head I can identify two primary factors: the first is that general public opinion suggests that wearing a helmet reduces the chances of death or brain damage should I be in an accident. The second was that my mother, who is a consultant peadiatrician, has seen the victims of bicycle accidents and is convinced that helmets have saved the lives of numerous patients that have entered her hospital.

I imagine that I am one of many people to have followed such reasoning and while I believe it to be both understandable and reasonable, I must admit that it is that my decision was not
logical in the truest sense of the word. In short, it is not based on educated, independent, unbiased reasoning- a process known as a full risk assessment.

One can not lead a normal life, as you and I understand it, fully evaluating the risk of every action. For most situations we use our judgment. For example, on deciding to cross a road on foot, one does not calculate the magnitude of the potential losses (one half of risk assessment) e.g. death, brain-damage, broken bones etc., and assign a value to each, then calculate the probability of each loss occurring (the second half of risk assessment) based on, in this case, traffic density, driving capabilities, athletic ability to dodge cars etc. and formulate a rational decision based these data. Instead, we, consciously or not, estimate... most of the time.

Eliot quite rightly brought up the issue that our estimates are often based on erroneous information. He provided an interesting graph (below- click on it to make it larger) showing the number of deaths per billion passenger kilometres for various transport types.

In other words, it shows the probability of dying by riding a motorbike one kilometre, compared to the probability of dying if walking 1km etc. and so on for each transport type.

This could be interpreted as "you are roughly 3 times as likely to die by riding a motorbike than you are if you walk". However, to gain perspective, and to understand the probabilities that we are dealing with, one can phrase it as "there is roughly a 1 in ten million chance that you will die if you choose to travel that 1km by motorbike, but a 1 in
thirty million chance if you walk".

As Eliot noted, and as is commonly cited, traveling by plane results in (according to this)
at least 26 times fewer deaths than traveling by car. It is important to note that this does not mean it is 26 times safer as the data only provides information on deaths.

So... returning to the topic in hand, it can be observed that probability of dying while cycling is on a par (it is in fact slightly higher) with the probability of walking. It is therefore understandable to suggest that since they are of roughly equal danger there should be as much (if not more- as the probability is slightly higher) encouragement for
pedestrians to wear helmets as there is for cyclists. This is the basis of Eliot's argument and although the suggestion is understandable, I believe it is misleading, as I shall outline below.

Although there exist some academic peer-reviewed articles suggesting reasons
not to use a helmet (provided in the link at the end), there is little doubt within the medical community that in the event of an collision, helmets themselves reduce the chance of sustaining a head injury and thus reduce the chance of death. The most widely-quoted case-control study, by Thompson, Rivara, and Thompson, reported an 85% reduction in the risk of head injury by using a helmet. However, as with most studies, critics exist. Suggestions that other factors were at play, for example, the cyclists that wear helmets ride more cautiously than those that do not. However, I am fairly sure that this is not the point Eliot disagrees with, so we can move on.

Now, although I am often victim to putting my helmet on far too early than is reasonably necessary, I have, as of yet, only heard of one pedestrian to wear a helmet (Eliot informed me of this person himself). However, I know of numerous cyclists that wear helmets religiously. While figures on helmet use vary (15%-80%), an estimate that 60% of cyclists in London wear helmets does not seem unreasonable. It is therefore reasonable to assume that the figures in the graph above would be different if I knew of only
one cyclist that wore a helmet. The effect would surely be an increase in the number of deaths associated with cycling. I think it would be foolish to attempt to put a figure on the extent of this increase but I would not be surprised if it at the very least it moved cycling into '2nd place' on the graph above, thereby making cycling more dangerous than walking.

In addition to this, the data does not seem to account for demographics. Although I can provide no specific evidence as yet, I imagine that children who have not developed the foresight of adults, are more often on foot (chasing a ball in the street for example) than on their bicycles. There are even several years (~2-7 yrs old) when children have not learned to cycle but can put themselves in danger as a pedestrian perfectly well.

On the other end of the spectrum, I know of more elderly who walk than cycle. I assume that this demographic have both the reduced ability to quickly react thus avoiding an accident
and (like small children now I think of it) an increased chance of dying, rather than being injured, should they be involved in a collision with a vehicle.


Now we are aware of the two key parts of risk assessment- 1. magnitude of potential losses and 2. probability that each will occur, we can make progress. For someone like him (and me) who cycles
far further than they walk, the question that needs to be asked is not 'if pedestrians don't wear one, why should cyclists?' but instead should be 'by how much does wearing a helmet reduce the magnitude of potential losses (e.g. sustaining head injury or dying?)'.

Should the final magnitude of potential losses be calculated and the probabilities of each of them occuring be identified, it is only then that enough information exists to complete a risk assessment.

In Eliot's case, if we really want to narrow the issue down, we need to ask two questions:

Question 1: 'What is the probability of...a male, aged 25, whose frontal lobe (the part of the brain that provides the ability to recognize future consequences resulting from current actions) is likely to be still developing, who is known to suffer from anger in traffic, who (admittedly after looking) goes through red lights, who enjoys going fast, who occasionally cycles without hands, who is likely to be easily distracted by hot girls, on a bike with only one brake ...getting into serious accident"

and

Question 2: What are the magnitudes of potential losses with and without a helmet?

Question 2 is the important one. To which, as discussed, there is substantial evidence for proposing significant reductions in magnitude.

One final point, with respect to question 1- the fact that he has had no serious incident thus far (a point I am sure he is thinking as he is reading this), albeit interesting, is not particularly relevant since (as you will recollect) the level of the probabilities in question are so small (1 in many
million) as is the time frame being considered (2 years- probably less than 600 journeys).


So... what conclusions? I hear you ask.

Well, yes... Eliot is correct in thinking that most of us have a distorted and often incorrect ability to perform risk assessment. I will include myself in the section of society that suffers from this- I would be lying if I said the thought of a plane crashing did not enter my head on
every flight I have been on, yet I have been in many car journeys without thinking of car crashes. However, I must also include Eliot in this group, since in the process of evaluating the risk, he is asking the wrong questions.

In addition to this, the argument that once the risk is fully established, it is still up to the individual to decide whether to wear a helmet or not, since choice over one's life is a basic human right- is not as bulletproof as it first sounds.

It is after all one's family and friends that have to look after brain damaged victims, seeing individuals once full of life and promise, be incapable of performing basic bodily functions without help. So, one could say that choosing
not to wear a helmet puts a burden on such people without having requested their permission. We are all in fact, actively encouraging him to wear one.

With all this being said, my reasons for wanting Eliot to wear a helmet are entirely selfish. Because, Eliot- if you were in an accident and died, I would really miss you... plus, who would I have to play mario kart with?

For more information, here is a link to an independent website that outlines all the arguments for and against the use of helmets for cycling.

and here is a PDF- with a summary of many academic articles on the subject.

"This is water, this is water"


This is an extract from an article I read in The Guardian celebrating the life and death of David Foster Wallace. It really struck a chord with me and I hope you enjoy it too.


There are these two young fish swimming along, and they happen to meet an older fish swimming the other way, who nods at them and says, "Morning, boys, how's the water?" And the two young fish swim on for a bit, and then eventually one of them looks over at the other and goes, "What the hell is water?"

If you're worried that I plan to present myself here as the wise old fish explaining what water is, please don't be. I am not the wise old fish. The immediate point of the fish story is that the most obvious, ubiquitous, important realities are often the ones that are the hardest to see and talk about. Stated as an English sentence, of course, this is just a banal platitude - but the fact is that, in the day-to-day trenches of adult existence, banal platitudes can have life-or-death importance. That may sound like hyperbole, or abstract nonsense. So let's get concrete ...
A huge percentage of the stuff that I tend to be automatically certain of is, it turns out, totally wrong and deluded. Here's one example of the utter wrongness of something I tend to be automatically sure of: everything in my own immediate experience supports my deep belief that I am the absolute centre of the universe, the realest, most vivid and important person in existence. We rarely talk about this sort of natural, basic self-centredness, because it's so socially repulsive, but it's pretty much the same for all of us, deep down. It is our default setting, hard-wired into our boards at birth. Think about it: there is no experience you've had that you were not at the absolute centre of. The world as you experience it is right there in front of you, or behind you, to the left or right of you, on your TV, or your monitor, or whatever. Other people's thoughts and feelings have to be communicated to you somehow, but your own are so immediate, urgent, real - you get the idea. But please don't worry that I'm getting ready to preach to you about compassion or other-directedness or the so-called "virtues". This is not a matter of virtue - it's a matter of my choosing to do the work of somehow altering or getting free of my natural, hard-wired default setting, which is to be deeply and literally self-centred, and to see and interpret everything through this lens of self.

By way of example, let's say it's an average day, and you get up in the morning, go to your challenging job, and you work hard for nine or ten hours, and at the end of the day you're tired, and you're stressed out, and all you want is to go home and have a good supper and maybe unwind for a couple of hours and then hit the rack early because you have to get up the next day and do it all again. But then you remember there's no food at home - you haven't had time to shop this week, because of your challenging job - and so now, after work, you have to get in your car and drive to the supermarket. It's the end of the workday, and the traffic's very bad, so getting to the store takes way longer than it should, and when you finally get there the supermarket is very crowded, because of course it's the time of day when all the other people with jobs also try to squeeze in some grocery shopping, and the store's hideously, fluorescently lit, and infused with soul-killing Muzak or corporate pop, and it's pretty much the last place you want to be, but you can't just get in and quickly out: you have to wander all over the huge, overlit store's crowded aisles to find the stuff you want, and you have to manoeuvre your junky cart through all these other tired, hurried people with carts, and of course there are also the glacially slow old people and the spacey people and the kids who all block the aisle and you have to grit your teeth and try to be polite as you ask them to let you by, and eventually, finally, you get all your supper supplies, except now it turns out there aren't enough checkout lanes open even though it's the end-of-the-day rush, so the checkout line is incredibly long, which is stupid and infuriating, but you can't take your fury out on the frantic lady working the register.

Anyway, you finally get to the checkout line's front, and pay for your food, and wait to get your cheque or card authenticated by a machine, and then get told to "Have a nice day" in a voice that is the absolute voice of death, and then you have to take your creepy flimsy plastic bags of groceries in your cart through the crowded, bumpy, littery parking lot, and try to load the bags in your car in such a way that everything doesn't fall out of the bags and roll around in the trunk on the way home, and then you have to drive all the way home through slow, heavy, SUV-intensive rush-hour traffic, etc, etc.

The point is that petty, frustrating crap like this is exactly where the work of choosing comes in. Because the traffic jams and crowded aisles and long checkout lines give me time to think, and if I don't make a conscious decision about how to think and what to pay attention to, I'm going to be pissed and miserable every time I have to food-shop, because my natural default setting is the certainty that situations like this are really all about me, about my hungriness and my fatigue and my desire to just get home, and it's going to seem, for all the world, like everybody else is just in my way, and who are all these people in my way? And look at how repulsive most of them are and how stupid and cow-like and dead-eyed and nonhuman they seem here in the checkout line, or at how annoying and rude it is that people are talking loudly on cell phones in the middle of the line, and look at how deeply unfair this is: I've worked really hard all day and I'm starved and tired and I can't even get home to eat and unwind because of all these stupid goddamn people.

Or if I'm in a more socially conscious form of my default setting, I can spend time in the end-of-the-day traffic jam being angry and disgusted at all the huge, stupid, lane-blocking SUVs and Hummers and V12 pickup trucks burning their wasteful, selfish, 40-gallon tanks of gas, and I can dwell on the fact that the patriotic or religious bumper stickers always seem to be on the biggest, most disgustingly selfish vehicles driven by the ugliest, most inconsiderate and aggressive drivers, who are usually talking on cell phones as they cut people off in order to get just 20 stupid feet ahead in a traffic jam, and I can think about how our children's children will despise us for wasting all the future's fuel and probably screwing up the climate, and how spoiled and stupid and disgusting we all are, and how it all just sucks ...

If I choose to think this way, fine, lots of us do - except that thinking this way tends to be so easy and automatic it doesn't have to be a choice. Thinking this way is my natural default setting. It's the automatic, unconscious way that I experience the boring, frustrating, crowded parts of adult life when I'm operating on the automatic, unconscious belief that I am the centre of the world and that my immediate needs and feelings are what should determine the world's priorities. The thing is that there are obviously different ways to think about these kinds of situations. In this traffic, all these vehicles stuck and idling in my way: it's not impossible that some of these people in SUVs have been in horrible car accidents in the past and now find driving so traumatic that their therapist has all but ordered them to get a huge, heavy SUV so they can feel safe enough to drive; or that the Hummer that just cut me off is maybe being driven by a father whose little child is hurt or sick in the seat next to him, and he's trying to rush to the hospital, and he's in a much bigger, more legitimate hurry than I am - it is actually I who am in his way.

Again, please don't think that I'm giving you moral advice, or that I'm saying you're "supposed to" think this way, or that anyone expects you to just automatically do it, because it's hard, it takes will and mental effort, and if you're like me, some days you won't be able to do it, or you just flat-out won't want to. But most days, if you're aware enough to give yourself a choice, you can choose to look differently at this fat, dead-eyed, over-made-up lady who just screamed at her little child in the checkout line - maybe she's not usually like this; maybe she's been up three straight nights holding the hand of her husband who's dying of bone cancer, or maybe this very lady is the low-wage clerk at the Motor Vehicles Dept who just yesterday helped your spouse resolve a nightmarish red-tape problem through some small act of bureaucratic kindness. Of course, none of this is likely, but it's also not impossible - it just depends on what you want to consider. If you're automatically sure that you know what reality is and who and what is really important - if you want to operate on your default setting - then you, like me, will not consider possibilities that aren't pointless and annoying. But if you've really learned how to think, how to pay attention, then you will know you have other options. It will be within your power to experience a crowded, loud, slow, consumer-hell-type situation as not only meaningful but sacred, on fire with the same force that lit the stars - compassion, love, the sub-surface unity of all things. Not that that mystical stuff's necessarily true: the only thing that's capital-T True is that you get to decide how you're going to try to see it. You get to consciously decide what has meaning and what doesn't. You get to decide what to worship.

Because here's something else that's true. In the day-to-day trenches of adult life, there is no such thing as atheism. There is no such thing as not worshipping. Everybody worships. The only choice we get is what to worship. And an outstanding reason for choosing some sort of god or spiritual-type thing to worship - be it JC or Allah, be it Yahweh or the Wiccan mother-goddess or the Four Noble Truths or some infrangible set of ethical principles - is that pretty much anything else you worship will eat you alive. If you worship money and things - if they are where you tap real meaning in life - then you will never have enough. Never feel you have enough. It's the truth. Worship your own body and beauty and sexual allure and you will always feel ugly, and when time and age start showing, you will die a million deaths before they finally plant you. On one level, we all know this stuff already - it's been codified as myths, proverbs, clichés, bromides, epigrams, parables: the skeleton of every great story. The trick is keeping the truth up front in daily consciousness. Worship power - you will feel weak and afraid, and you will need ever more power over others to keep the fear at bay. Worship your intellect, being seen as smart - you will end up feeling stupid, a fraud, always on the verge of being found out.
The insidious thing about these forms of worship is not that they're evil or sinful; it is that they are unconscious. They are default settings. They're the kind of worship you just gradually slip into, day after day, getting more and more selective about what you see and how you measure value without ever being fully aware that that's what you're doing. And the world will not discourage you from operating on your default settings, because the world of men and money and power hums along quite nicely on the fuel of fear and contempt and frustration and craving and the worship of self. Our own present culture has harnessed these forces in ways that have yielded extraordinary wealth and comfort and personal freedom. The freedom to be lords of our own tiny skull-sized kingdoms, alone at the centre of all creation. This kind of freedom has much to recommend it. But there are all different kinds of freedom, and the kind that is most precious you will not hear much talked about in the great outside world of winning and achieving and displaying. The really important kind of freedom involves attention, and awareness, and discipline, and effort, and being able truly to care about other people and to sacrifice for them, over and over, in myriad petty little unsexy ways, every day. That is real freedom. The alternative is unconsciousness, the default setting, the "rat race" - the constant gnawing sense of having had and lost some infinite thing.

I know that this stuff probably doesn't sound fun and breezy or grandly inspirational. What it is, so far as I can see, is the truth with a whole lot of rhetorical bullshit pared away. Obviously, you can think of it whatever you wish. But please don't dismiss it as some finger-wagging Dr Laura sermon. None of this is about morality, or religion, or dogma, or big fancy questions of life after death. The capital-T Truth is about life before death. It is about making it to 30, or maybe 50, without wanting to shoot yourself in the head. It is about simple awareness - awareness of what is so real and essential, so hidden in plain sight all around us, that we have to keep reminding ourselves, over and over: "This is water, this is water."
