Is the book trade too left wing for its own good?

I like to drop into the excellent Riverside Bookshop on Tooley Street, London SE1 (late of Hays Galleria). It has a good selection and dedicated staff (even if they blot their copybook slightly by not stocking my book God's Philosophers). Further afield, Daunts have a branch in Cheapside which is also worth a browse and Waterstones have some outlets in the City as well. But, given their location, I do wonder about the political emphasis of these establishments.

You might think that in the heart of London's financial district, the bookshops would reflect their potential clientele. After all, the big accounting firms have offices housing over 5,000 diligent bean counters (including me) within a couple of hundred yards of the Riverside Bookshop. Accountants are not usually at the vanguard of the Occupy protests and we rarely plot to overthrow global capitalism. In fact, many of us are secretly quite fond of market economics, recognising that it is responsible for the unprecedented reduction in global poverty over the last couple of decades.
But despite all the well-heeled capitalists just around the corner, City of London bookshops seem determined to promote left wing books rather than conservative ones. On the non-fiction stand at the Riverside Bookshop we find Owen Jones on The Establishment. At least Jones can write; but he is sharing space with the latest tedious polemic from Polly Toynbee, something on the contradictions of capitalism by Marxist David Harvey, and Naomi Klein's climate change screed. The only conservative book on offer is Andrew Robert's quixotic paean to Napoleon.

Then I had to ask myself, what are the current bestselling conservative books? Looking through the Amazon top 100 non-fiction, Boris Johnson is the only right winger in view. The publishing trade itself appears to have a marked left wing bias. Students are big buyers of books, especially non-fiction, and they tend to be left wing. That alone might account for the bias of the book trade as a whole. But that doesn't make it a good idea. Currently, the UK printed book market is worth just £1.4bn a year and is shrinking. By comparison, the video games market is a growing £2.2bn while telecoms is a massive £40bn and cars a whooping £60bn. Economically, books are not very significant. So you would think that the trade would be trying to reach as many potential readers as possible.

This means that local bookshops in areas that are likely to be conservative, like the City of London or a leafy shire town, need to work a bit harder with their buying decisions. They have to search out the books that their clientele are likely to enjoy. And having done that, they need to promote them, since readers won't necessarily be aware of them from the national scene. That does not mean having a separate section for these sorts of books, keeping them quarantined from everything else. Treat them as what they are - part of mainstream thought rather than left wing rabble-rousing.

As a help to bookshops who'd like to sell more non-fiction books to their centre-right customers, here are five excellent titles that they should stock and, just as importantly, promote front of house with those little handwritten signs about how good they are.

1: Matt Ridley The Rational Optimist - why it is a thoroughly good thing that the facts of life are conservative

2: Daron Acemoglu and James Robinson Why Nations Fail - the importance of the rule of law and free markets in making countries richer

3: Jonathan Haidt The Righteous Mind - the psychology of narrow-minded lefties and broad-minded conservatives (written by a liberal)

4: Daniel Hannan How We Invented Freedom - the story of how the Anglosphere became the most liberal and prosperous countries on Earth

5: Steven Pinker The Blank Slate - human beings are not products of their upbringing and the environment (also written by a liberal)

The earliest reference to a telescope: England 1551?

“And hereof came it that Fryer Bakon was accompted so greate a negromancier, whiche never used that arte (by any coniecture that I can fynde) but was in geometrie and other mathematicall sciences so expert, that he coulde dooe by theim suche thynges as were wonderfall in the syght of most people.

“Great talke there is of a glasse that he made in Oxforde, in which men myght see thynges that were doon in other places, and that was iudged to be done by power of euyll [evil] spirites. But I knowe the reason of it bee good and naturall, and to be wrought by geometrie (sythe [since] perspective is a parte of it) and to stande as well with reason as to see your face in common glasse.”

The quotation above comes from the preface to a textbook on geometry called A Pathway to Knowledge published in London in 1551. It was written by a doctor and mathematician called Robert Record (1512 – 58). His arithmetic textbook, Ground of the Arts, first published in 1543, was popular with students by virtue of being in English. It went through over 40 editions right the way to the end of the seventeenth century.  Record is probably best known for his invention of the equals sign.  However, despite his relative success as an author, he died in a debtors’ prison.

Of course, the quotation is most interesting because it describes a device that sounds much like a telescope, sixty years or so before the telescope was supposed to have been invented.  “Fryer Bakon” is Roger Bacon OFM, the Franciscan scholar of the thirteenth century famous for his Opus Maior and Opus Minor who lectured at the Universities of Oxford and Paris.  He may have been (but probably wasn’t) imprisoned for a time for his adhesion to the ultra-ascetic wing of the Franciscans.  His reputation for necromancy was a not uncommon trope in sixteenth-century England where he was a famous historical figure.  However, the accusation of black magic is almost always found in the context of a denial that he was, in fact, a magician. 

Record’s preface is a good example of this kind of defence of Roger Bacon.  The specific charge is that Bacon had a device that allowed him to see what was going on in other places.  Record says the device was not magical but used Bacon’s knowledge of perspectiva, what we would call geometrical optics.  Bacon was indeed familiar with this subject and wrote a treatise on it.  In this treatise, he mentions magnifying glasses and, as it happens, spectacles were invented in Italy shortly thereafter.
To be clear, there is no evidence that Bacon had any device to see different places, magical or otherwise.  What interests me is what Record thought Bacon had invented.  The device mentioned in the quotation does not sound like a magnifying glass or spectacles.  In any case, if that was what Record had in mind, he would just have said so (probably calling a magnifying glass a “perspective glass”, which confusingly was also an early term for the telescope). 

I think there are three possible interpretations of Record’s words:

  • Record has no idea what he thinks Bacon’s device was.  He just wants to reassure his readers that it would have been built on mathematical and not necromantic principles.  This is possible.  Record is making a point that geometry is jolly useful.  But the passage reads as if he knew what the device was supposed to be and how it worked.

  • Record thinks the device was a periscope.  These had been invented a hundred years before Record wrote by Johan Gutenberg, who lost money on the venture.  Gutenberg later had more success as a pioneer printer.  The trouble is, periscopes don’t really show you what is going on in another place.  But they do allow you to see around corners, so this interpretation is a possibility.

  • Record has in mind a device like a telescope that really does let the user see things where he isn’t.  Hans Lippershey famously patented the first telescope in 1608, but several others claimed to have invented it.  This certainly best fits the context of the passage but would require that Record knew what a telescope was before it was supposedly invented.

So could Record really know about a telescope as early as 1551?  Astronomer Colin Ronan has claimed that it was invented by a Kentish mathematician and astronomer called Leonard Digges (d 1559).  The claim is actually made by Digges's son Thomas (d. 1595) on his father’s behalf.  Digges Jr produced an edition of his father’s book on practical geometry called Pantometrica which was published in 1571.  In the introduction, he notes:

“… my father by his continual painful practices, assisted with demonstrations Mathematical, was able, and sundry times hath by proportional Glasses duly situate in convenient angles, not only discovered things far off, read letters, numbered pieces of money with the very coin and superscription thereof, cast by some of his friends of purpose upon downs in open fields, but also seven miles off declared what hath been done at that instant in private places.”

This does sound a lot like the device mentioned more briefly by Record in the preface to The Pathway to Knowledge.  It would be great to be able to link Record and Digges directly.  Unfortunately, Record was based in Cambridge in the 1540s, Digges in Kent.  But Record was reasonably well-known after 1543 thanks to his arithmetic book Ground of the Arts.  Among the small community of English mathematicians, Digges and Record, both avid Protestants, could have met.

Overall, I think there is a good chance that Record is referring to a telescopic device in 1551 and if so, this is most likely to be the same one that Digges had invented.  At least, Record seems aware that a telescope exists even if he has not seen one.  If this is the case, it is evidence that Digges really did create telescope before 1551 and makes Record’s preface the earliest reference to it.
