To begin, just a heads up on a couple of new things on the site. First, I’ve posted on the My Book page advanced comments about my forthcoming book that have come in from a number of interesting thinkers. It’s nice to get such positive notices. Currently, I’m pretty busy gearing up for the book launch on 15 October (21 October in the USA) and I’ll be devoting some blog posts to the book thereafter.
Also, an interesting comment has come in concerning my house rules on the About page, to which I replied here. I don’t promise to debate my rules with all comers, but I think the issues in this instance are thought-provoking, so I (cautiously) welcome further comments.
And now to work with a few thoughts on science and alternative agriculture, inspired partly by this article and partly by the themes explored in Chapter 16 of my book (“From religion to science (and back)”). I’m not going to engage systematically with either source, but instead just use them as points of departure for a few remarks concerning the need as I see it for many of us in the alternative agriculture movement to develop a more nuanced approach to science.
Let me start by invoking a distinction I made some time ago between what I call ‘science’ and ‘SCIENCE’. Lowercase ‘science’ is the everyday, generally unglamorous work that scientists do in laboratories, field study sites and the like, where they use carefully-formulated techniques to tease out the relationships between entities in the biophysical world. A vital aspect of ‘science’ in this sense is that the people engaged in it – almost uniquely in human discourse – have developed rigorous procedures for conceding when they’ve got things wrong and the evidence doesn’t support their contentions. Science involves rigorously self-critical scrutiny. There are arguments about the wider philosophical commitments involved in doing science of this sort, but for my part I have very little quarrel with ‘science’ as I’ve described it here – if you want to figure out what’s going on in the biophysical world, it’s pretty much the only game in town.
By the way, you don’t really need to be a scientist to do science. A lot of growers and farmers do ‘scientific’ experiments all the time. Being amateurs, farmers usually lack both the resources and the expertise to do science of sufficient rigour to meet the quality criteria necessary to contribute to the professional scientific record, but we can still usefully inform our practice with some rudimentary knowledge of scientific methods and a healthy dose of self-critical scepticism.
It’s this self-critical scepticism that’s missing from the other kind of science, which I call uppercase SCIENCE. SCIENCE is a political claim that the human world should be organized in a particular way on the basis of ‘scientific principles’ or what ‘the science’ tells us to do, or other formulations of that sort (some people call this scientism). It’s in play when, for example, someone counterposes ‘scientific’ agriculture (good) with peasant agriculture (bad). SCIENCE isn’t really about science and can claim little or no warrant from the work that scientists do. Sometimes advocates of SCIENCE are scientists (who, after all, are only human) but its loudest advocates are often non-scientists wishing to invest their beliefs with a patina of authority.
Indeed, SCIENCE has a strong hold on our imaginations because science has been spectacularly successful in comprehending and intervening in the biophysical world. So it’s not surprising people want to warrant their social or political beliefs in its name. But you might as well claim a warrant from God, for whom in fact SCIENCE is a modern substitute. The reason that science has been so successful is precisely because it isn’t SCIENCE.
It would be easy to detail the many ways in which scientific work has too easily become a stooge of large-scale, corporate-dominated SCIENTIFIC agriculture in the modern world, and on these points I largely agree with the article I linked above. But I’d like to look at the flipside of this in alternative agriculture, which I’d argue stalks this passage in the same piece:
It is ironic that would-be scientists insist on seeing new discoveries and work printed in peer-review literature because they really have no understanding what they are asking. Pioneers have no peers and certainly no peer publications to publish their work. When Bruno suggested that the earth revolved around the sun, he was put to death by his peers. Galileo was threatened with torture by his peers for suggesting the same thing. …. Peer review is actually political review, designed to determine whether the work alienates the monopoly…Are non-astronauts peers of astronauts? Are non-presidents peers of presidents? Are non-pioneers peers of pioneers? I say. No. Pioneers have no peers except other pioneers. The emphasis on peer review should be secondary to results in the field. It is in the field that farmers, gardeners, and landscape “doctors” are either made or broken.
The only part of this passage I really agree with is the last sentence. Like shopkeepers, farmers have no fundamental need for scientific evaluation of their practice because the criteria for judging results in the field (or the shop) rest in their own hands. Unlike the work that scientists do that absolutely requires external validation (let’s call it peer review), the only validation a gardener or a farmer really needs is their own – “this works for me” (hence the usefulness of farmers being their own scientists to check as best they can that it does actually work for them).
So why might farmers seek scientific evaluation of their practice? Undoubtedly, often for a number of good reasons, but also sometimes I think for a less good one – they want it validated by something with a powerful social cachet. The problem is, as soon as they look to science for validation of their practice rather than as a means for self-critical engagement with it, they’re doing SCIENCE, not science. And, all too often, such SCIENCE works as a thoroughly unscientific social status claim – follow what I do and don’t question it, because my work has been proven to be SCIENTIFIC.
I’ll concede that there’s quite a lot of this SCIENCE in the world of professional science, though the institutional practice of science as self-critical inquiry usually ferrets it out in the end. But what I want to warn against here is the dangers of succumbing to the siren song of SCIENCE in the world of alternative agriculture. I’m not going to name names or give specific examples. I’ve done it in the past, and I don’t want to rake over old antagonisms again. Instead, I offer this five-point checklist that I hope might help alternative agriculturists avoid the temptations of doing SCIENCE rather than science. And, just to be clear, yes I need to learn from it myself.
- Welcome nay-sayers. Nay-saying is why science has achieved so much. You think outcome x results from practice y? Great, but perhaps you’re wrong and somebody who’s questioning you might put you on a better track. There’s no need to be browbeaten off your chosen path by nay-sayers, but every reason to listen and maybe learn from them instead of simply nay-saying their nay-saying. Nay-saying can be beautiful!
- A complex, real-world practice like farming or gardening involves innumerable variables that are extremely difficult, costly and time-consuming to tie down scientifically. And there are places where science can’t really go, at least not yet. So it’s OK to farm by hunches and intuitive results. A lack of scientific warrant for your practice doesn’t necessarily mean it has no virtue. But it might mean it has less virtue than you thought, and it’s as well to be alive to that.
- Farming can be context-specific. Person A seeking farm outcome B in place C might hit upon some novel and elegant solution D which they believe should be practiced more widely. However, if person E seeking farm outcome B or similar in place G implements solution D on the basis of a superficial applicability, there’s a good chance it won’t work out so well. In these circumstances, it’s tempting for person A or their followers to fault person E, but that’s probably not the first place to look in order to understand where things went wrong.
- Please don’t, just don’t, compare yourself to Galileo and berate others for ignoring your peerless originality. It’s true that the institutional structures of scientific validation are conservative, and a downside of this is that false negatives do occur, with the odd Galileo slipping through the net and failing to get the hearing they deserve. Regrettably, though, there are many, many more people who consider themselves to be latter-day Galileos but, um – how can I put this delicately? – actually aren’t, and an upside of scientific discourse is that it filters out most of these false Galileos and saves the rest of us a lot of time.
- To put this another way, there’s an enormous danger of hubris in considering oneself a pioneer whose only peers are other pioneers. If you consider yourself to be pioneering new ways of farming or gardening, I’d suggest that your peers are neither other pioneers nor scientists but ordinary, common or garden farmers and gardeners like me, along with innovators of the past who slowly worked out the tried-and-tested methods we’ve inherited. If you’re truly onto something that they can’t appreciate, well, too bad for them. The world will probably catch up eventually – as when the Vatican finally admitted that Galileo was right in, er, 1992. So I’d urge you to do your pioneering with humility and a measure of self-doubt, using the scepticism of others to inform further reflection and improvement. If you can do this, then, truly, you’re a scientist, whether or not you have the PhD to prove it. And this is a rare and precious thing. SCIENTISTS, on the other hand, are ten a penny.
Finally, despite directing my comments here towards alternative agriculture, let me concede that they apply all the more forcefully to mainstream agricultural discourse and its numerous idols of the moment – vertical farming, industrial eco-gloop and so on. False Galileos are everywhere.
