In the Round
Leonardo da Vinci said almost the same thing in his treatise on painting. There is great truth in the statement that the essence of the plastic arts (painting, sculpture, drawing, etc.) resides in the ability to project roundness as it implies a discipline whereby the mind can conceive of and manipulate three-dimensional forms in its imagination -- a skill that masters like Leonardo, Ruskin, and others considered both rare and difficult. (Worth pondering why that is.) If the object of painting is to simply 'represent' lines and shapes that create an illusion of solidity -- then this idea is not interesting, it is simply another technical trick. But if the object of painting is to conceive of three-dimensional forms in the mind and project them onto a plane, it is an entirely different story as we are talking about not a mechanical trick but a mental operation -- perhaps not different from the ability of the musical composer to interweave melody and harmony and to think in counterpoint. It is the difference between the blind application of some rules ... and the very power of the imagination to think literally in several dimensions at once, to interweave and play with forms in space, to communicate awful feelings of depth; expansive feelings of volume; profound sensations of weight and mass and cohesion. And when the object of the painter's attention is not just any old round shape but an organic form, like the human or animal body, or a landscape, the power for these sensations to move us is vastly amplified, through our innate sympathetic attachment to natural forms. Of all these, the human body is of course the most sympathetic as its nervous system is a thing we have intimate knowledge of -- so to draw this truly in the round, where the three-dimensional counterpoint of muscle and bone and tendon and flesh is woven into a human fugue and animated with human passions, well, to draw 'in the round' in such a way is a very profound experience -- and is a long, long way from merely imitating the inclination or declination of some perspective lines.

The Tale of Two Revolutions
It is hard to disagree with him -- at least with the sentiment. I agree that it's somewhat depressing that Keynes's prediction did not come to pass, but this line of thought does verge awfully close to conspiracy thinking. It seems to impute that there is some force beyond the market ordaining the creation of non-essential jobs in the interests of social repression. But while this often feels real -- I've often wondered why we have to work 40+ hour weeks, and why most jobs aren't at least shift-based (which would surely maximise opportunities to consume) -- it's not conceivable that thousands of companies are coordinating a campaign of full-time employment merely for the hell of it, or to 'keep down' the people.
The conclusion is perhaps more depressing than the failure of Keynes's prediction: these bullshit jobs exist because, whether through a failure of imagination or technology or both, there is an administrative need for them. It has been said that the invention of the computer created an Information Revolution in the same way that machines and steam power created the Industrial Revolution. But has anyone thought to follow that parallel further? How pleasant was the Industrial Revolution for the average worker, intellectually and aesthetically brutalised as they were by repetitive labour which they had no creative input into? Has the Information Revolution been any better for the average information worker in terms of creative fulfillment? Perhaps what the two revolutions have in common is the same brutalisation of the spirit by mechanisation. Does it matter much, intellectually, whether you're a cog in the computer or a cog in the machine? Of course I'm not comparing the quality of life in physical or health terms, or in many other ways. But as John Ruskin deduced in his famous chapter on 'The Nature of the Gothic' in 'The Stones of Venice', the happiness of a craftsman is ultimately dependent on the amount of freedom that they can exercise in their craft. Without this freedom -- which is also the freedom to be inefficient, to make mistakes, in other words, to learn -- then the creative spirit of the worker is debased by their trade. In this sense, working at the keyboard can be just as brutalising to the creative spirit as working at the loom.
While reducing the working week from 40+ hours to 30 or even 20 would obviously be desirable, it would not necessarily fill the creative void. More opportunities for pleasure do not necessarily lead to pleasure -- they can just as easily lead to anomie and boredom (see the plight of the long-term unemployed). Work provides structure and consistency -- backed by the social obligation to turn up, to not disappoint -- and that does give people a sense of purpose that can often be lacking with unstructured free time (whether unemployed or merely on holiday). What is really depressing about this is that this could simply be down to a colossal failure of imagination -- the imagination required by society to find forms of play (as opposed to work) for people that are not just as compelling as work but that stimulate more personal growth and consequently greater social benefit.

Negahertz
Negahertz (NHz): Noun - The unit of measurement of the amount of frustration created by unnecessarily slow software and operating systems.
My reawakened passion for vintage computing has changed my perspective on modern computing in various ways. One thing that leaped out at me recently was the discovery that old computers aren't necessarily slower than new computers. Of course computers today are millions, even billions of times more powerful than any high-end personal computer from the 1980s. But until recently the everyday experience of using a modern computer has usually been characterised by blissful periods of speed and productivity interlarded with teeth-grinding delays. These delays, these periods of software- and operating-system induced gridlock, I describe with the term "negahertz."If the number of megahertz equates to how fast a computer is in theory -- or used to -- then negahertz equates to how slow the computer actually feels in practise. There are plenty of ways that an old computer system can feel faster than a new one. Anyone who grew up in the 1980s will remember switching on a personal computer -- like an Atari 800XL or an Apple //c in my case -- and booting almost immediately into a usable programming environment. Before the days of multitasking graphical user interfaces it was possible to fit a computer's operating system and a built-in programming language comfortably onto ROM. (Although, once Apple invented the graphical user interface it was no longer possible to fit an entire operating system in ROM.) Bigger storage devices and faster CPUs spurred companies on to develop ever bigger and more capable operating systems, but at the price of turgid boot sequences and often sluggish interfaces. Computers went from being under-powered machines that were productive in seconds, to over-powered machines that took longer to start than it took to boil a kettle. If you think about it this is a strange concept -- strange that we, the all-powerful consumer, meekly put up with it for so long. (Of course, it's not like there were any alternatives.)
The concept of negahertz has encouraged me to look at the reality of using a computer -- and not the technical stats driven fantasy of clock cycles, revolutions per minute, or bus speeds. All of those wonderful developments in raw speed and power can be crippled by software bureaucracy and the mire of abstractions. Just as negawatts encourages you to think of where energy is wasted -- and can therefore, if desired, be saved -- negahertz has made me think more about what a computer could and should be. A machine that puts the needs of users first -- that may not be blazingly fast but is instantly responsive; that doesn't bring interaction to a halt while the file system is busy; that has a graphical paradigm that creative programmers can expand upon, instead of being straitjacketed by; that is understanding and tolerant of errors and mishaps and that puts a smooth and stress-reduced experience first.
Of course, it is not all gloom and doom. Far from it. In fact, we may be seeing the best of both worlds: a humane user experience driven by inhumanly fast hardware. The smartphone and tablet revolution has finally forced complacent operating system vendors to take boot times seriously and to prioritise the responsiveness of the user interface -- as they should always have done. This betterment of experience and improvement in perceived performance has not been the direct or necessary outcome of faster hardware -- it has emerged because consumers un-purchased and un-bought slow and buggy mobile devices into oblivion. Those who wished to survive shifted their priorities accordingly.
In the meantime, I find it a fun mental exercise to now rate slow-loading apps and websites in negahertz -- and to imagine how, with the right ideas, hundreds or thousands of negahertz could be saved.

A good haul
It also helps to have clearly defined criteria beyond the author or subject matter. I was looking for good condition antiques this time, and the haul includes the following:
Most were art books or art criticism ...
2 x Kenneth Clark (HB, 1st);
3 x John Ruskin (HB, 1890s);
2 x William Gaunt (HB, DJ, 1st);
Along with some curiosities:
A beautifully illustrated (watercolour) hardback on Belgium by Forestier & Omond from the '20s;
The real find of the booksale was probably a 1930s edition of The Rubaiyat of Omar Khayyam, 1st & 4th Fitzgerald translation, illustrated by Willy Pogany, gilt edging intact.
After all these years there is no damage to the black-and-gold bookplate stuck to the cover.
As well as a dozen beautiful tipped in colour reproductions there are these black-and-gold stuck on block illustrations. Arabesques, florilegia, fantastic urns, grotesque anamorphic forms that grin like gargoyles.
It is a strange but not displeasing mixture of chaste classic line, Arabian Nights atmosphere, and a lady who could sway out of the pages of an Art Deco fashion catalogue.
I also chanced on a catalogue of a Justin O'Brien retrospective, an Australian academy-trained modernist who painted in a loosely Siennese style.
I think this is marvellous painting in its primitive, urgent colour, and in its austere counterpoint of volume and void. O'Brien is a modern who has enriched himself with the passionate study of masters who suited his temperament. There is no straining, no reaction, no rebellion. The work has the timelessness of a Duccio or a Puvis de Chavannes. But with Chavannes I am pulled up on the question of spiritual content. Like Chavannes there is purity of colour, grandeur of form, serenity of temperament. But what is the painting's contribution to the summa of Christian art? Not having been Christian in 20 years I'm not one to offer an ultimate affirmation or denial. But it strikes me that works like this don't positively add to the Christian tradition so much as offer a lyrical interlude. Time is suspended, and you find yourself back in 13th century Tuscany, but of fresh religious inspiration, prophetic insight, I see no sign. But then, the greatest popular Christian thinker of the time was probably an ironist, G.K. Chesterton, compared to figures like St. Francis and Dante who would have inspired O'Brien's idols. At least he didn't howl to the whirlwind.
Also, two calf-skinned volumes of Wordsworth and Tennyson. So sensuous to touch it ought to be perverse.
Again, a quarto of sculpture from India, Khmer, Cambodia. The perfect companion to the Roger Fry 'Last Lectures' recently acquired ...
And lastly :
Two 1st eds (I think), hard cover and dust jacketed Frank Herberts and Douglas Adams: 'Chapter House Dune' & 'Mostly Harmless'.
A good haul this year.
