In a world where bigger equals better, and faster is more, it is a radical notion to focus on the small and the slow. Why would you, if you could have it bigger and faster? The answer to this should be (hopefully) quite obvious. Let's consider an example that has no doubt already crossed the mind of some readers: A car!
Suppose I gave you the option between two cars to chose from (which I would give you for free): a small compact car, or an SUV. Clearly, the obvious choice is the SUV, until you consider gas mileage, parking spaces, and general city traffic. Certainly, it all depends on your given conditions and your needs. Maybe gas is really cheap where you live. Maybe you don't have to deal with city commutes. Maybe you need to haul big things. Lots of a times having a big vehicle is perfectly reasonable. Lots of other times it's not. But this example is just scratching the surface.
When discussing this point in his book Permaculture Principles and Pathways, David Holmgren mentions bicycling or walking as opposed to driving. Their advantages should be obvious: you get to experience the world you're passing through with all your senses, you smell the air, you feel the ground under your feet, you can stop and enjoy the scenery. All things you would miss out traveling inside a car or a train.
Or let's take completely unrelated examples, such as romance: A long and elaborate courtship is more likely to become a lasting and more fulfilling relationship than a quick and rapid conquest. Sure, maybe not for everybody, just like in the case of the SUV. Though Milan Kundera's book Slowness talks precisely about this, suggesting that it may apply to many of us.
Finally, to use an example close at hand, the growth of any business, game, or whatever is in between, such as Steemit. As nice as it felt to see a reward of 250 bucks for my third post, ultimately it raised my expectations way beyond what's reasonable, making even a decent $12 payout feel disappointing. Instead, it is much nicer to see gradual growth and appreciate the small increases.
Permacultue, as we need to keep in mind, is not only about gardening, but includes the entire scope of our existence and day-to-day activities. However, to stay in the garden for a bit, let's consider its obvious advantages compared to huge industrial-scale farms. Sure, the yield of a small backyard is obviously limited by its size. On the other hand, it is clearly more flexible, more diverse, and much more independent than an industrial plot of monocrop, which by its nature relies on machines (plus fuel, parts, etc.), chemicals (their production, application, and subsequent health treatment), and a huge supply network, balanced market prices, just to mention the most obvious things. Keeping all this in mind, it comes as no surprise to see articles like this one, describing how small scale organic gardening (as it's common in Russia and many other places) is the most efficient way to provide food, looking at all pros and cons.
One of the most ingenious inventions of nature is the cell. Instead of growing bigger and bigger, it kept the basic building block at a small size. Together these individuals would form a network as a tissue, which in turn could perform other functions. Big enough to offer a sufficient complexity, a cell is still so small that it takes a multitude of them to perform any function. They are individual, autonomous beings, who live, act according to their needs and circumstances, and eventually die. Being so small, the death of one individual will not affect the organism as a whole. On a larger scale, isn't this just like a vast network of small organic gardens?
At this point I'd like to bring up E.F. Schumacher's famous book Small is Beautiful. Contrary to what the title indicates, he does not advocate small per se. Instead, he emphasizes the right scale, meaning human scale. This way it is not the industry, the economy, or the company whose needs are prioritized over that of ours, as it is too often the case. It is rather humans who can design systems for themselves (and each other) that will be geared to fulfill their needs, while still considering the needs of others (humans, nature, resources, …) in a way that is just as flexible, autonomous, and complex as we like. No more, no less.
Instead of theorizing around much more, here are some concrete examples for slow and small:
