The Historically Contingent Origins Of Modern Science

[DocWatts]

Howdy! Thought I might share this write-up I did on the origins of modern science, which delves into how our intuitions about relevance (what is and isn't considered important for a particular problem) inform our problem solving frameworks. This write up is prelude to a deconstruction of scientific realism for the philosophy book I've been writing, 7 Provisional Truths.

Enjoy!

Horizons Of Relevance

The crux of empiricism's staying power, in both its early and scientific incarnations, stems from its broad applicability to a wide range of practical problems. The key to this versatility? It’s tied to why our problem-solving frameworks are useful to us in the first place. Just as tools empower us to shape raw materials into desired forms, methodologies such as empiricism equip us to steer events towards desired outcomes. Put simply, a methodology is a structured, replicable practice for guiding actions towards an intended purpose. When working as intended, the guidance that these frameworks provide isn’t arrived at by happenstance. It instead follows from successfully pinpointing what’s relevant for a particular problem.

While pinning down what’s pertinent to a given goal may sound straightforward, it can be deceptively complex. Our  lifetime of experience with everyday tasks tends to mask the formidable challenge of discerning relevance in situations where we lack this expertise. The process of determining what's salient - that is, what stands out as important - for a given purpose is known within cognitive science as relevance realization. While it’s yet to become a household term, relevance realization exposes a pivotal aspect of our problem-solving that's easily overlooked in folk-epistemology.

The development of germ theory aptly exemplifies many of these challenges. It shines a spotlight on how our intuitions of salience can be highly misleading, while revealing the ease with which outcome-determinative factors can elude the untrained eye. While it’s become common sense that diseases are transmitted by germs spread through bodily fluids and contaminated material, this wasn’t evident to anyone just a few centuries ago. The existence of microorganisms, not to mention their power to disrupt our bodily processes, isn’t an inference that’s readily drawn from surface-level observation. 

The barrier to connecting these dots can be traced back to the environmental context that our perceptual abilities are adapted to. In essence, our sensory systems are evolutionarily calibrated to an intuitive, human-centric scale. Think of this perceptual baseline as the person-sized ‘factory setting’ to which our experience of both space and time is instinctively attuned. To borrow and extend a term from meteorology, let’s call this anthropocentric frame of reference the mesoscale (from the ancient Greek words for 'middle' and 'size'). So what’s the link between the mesoscale and our intuitions about relevance? The connection is that it’s our perceptual canvas for drawing inferences from our embodied experience.

Though our intuitions of relevance are formed at the mesoscale, this anthropocentric realm is just a tiny slice of Reality. Venturing beyond this familiar domain poses a number of unique challenges, beyond the fact that phenomena become  difficult to observe and manipulate as the scale shifts away from our day-to-day perspective. At extremely small and large scales, everyday phenomena can behave in very counterintuitive ways. Take water, for instance. While its behavior is well accounted for at the mesoscale, from an ant’s point of view water becomes a sticky, globule-like substance with significant surface tension. And from a planetary vantage point, its currents shape the climates of entire continents as it circumnavigates the globe.

Moreover, we often fail to grasp how day-to-day phenomena are intrinsically linked to processes operating at temporal and spatial realms vastly smaller or larger than our habitual frame of reference. Returning to our water example, for most of human history it would have taken a feat of imagination to connect the ocean tides to the invisible pull of the distant moon and sun. That is, until Newton's field guide to universal gravitation upended our cosmic perspective. By the same token, attributing the air that we breathe to the waste products of tiny, invisible creatures in the oceans would have seemed equally far-fetched. Then imagine Leeuwenhoek’s surprise at his chance encounter with microbes from tinkering with glass lenses - and how this discovery would go on to change the world.

The basic takeaway is that our habitual intuitions about relevance are tightly bound to the mesoscale that serves as our stage for daily life. While early empiricism probed the limits of this human-sized backdrop, venturing beyond its comfortable boundaries requires highly specialized techniques. Which brings us to the innovations that the scientific method brought to empiricism - and how its transformation of daily life propelled this methodological toolkit into a bona fide folk-theory of Reality. 

But before we part the veil of scientific realism, it will be instructive to touch upon the historical contingencies that gave birth to modern science. Lest we forget, the scientific method wasn’t an inevitability, and its successes were far from guaranteed. Instead, the achievements that would propel the popular image of science from a specialized mode of inquiry into  a de facto ‘theory of everything’ weren’t preordained. Far from mythological depictions of science as a universal cipher to ‘life, the universe, and everything’, it’s important to keep in mind that the science method was invented - not ‘discovered’. In keeping with our theme that our human perspective within Reality is an essential feature of our problem solving frameworks, the story of science can be traced to a specific time and place that was ripe for an epistemological revolution.

The Historical Foundations Of Modern Science

The iterative toolkit that would become modern science found its initial foothold in 16th and 17th century Europe, amidst a convergence of highly contingent social factors. A Pandora’s Box of socially disruptive forces was busy uprooting European civilization from feudalism, which had taken root in the ruins of the Western Roman Empire. 

The prevailing social order, consisting of subsistence farmers bound in hereditary service to a military aristocracy,  had been devastated by the Black Death - a civilizational apocalypse that wiped out a third of Europe’s population. Carried by flea-infested rats who’d made themselves at home amidst the open-sewers and waste-filled streets of European towns and cities, the fetid conditions of daily life were ripe for this plague to spread its tendrils into every corner of society. Sparing neither cities nor countryside, Europe experienced rapid depopulation over just a handful of years, shattering the demographic foundations that had sustained feudalism for centuries. With laborers now worth their weight in gold, centuries of feudal bondage began to crumble, sowing the seeds of a transformative zeitgeist which would go on to change the world.

From feudalism's ashes, a new social order was coalescing around a form of economic activity that historians would later term mercantilism. Driven by commercial interests and secured by maritime power, cosmopolitan exchange was the lifeblood of this new order, flowing into Europe from the New World. Of course, this early form of globalization bore little resemblance to ‘peaceful exchange’ - it was enforced with brutal systematicity through guns, germs, and steel. 

Alongside these developments, the Protestant Reformation had loosened the Catholic Church’s iron grip over European thought, undermining its ability to suppress knowledge perceived as a threat to its authority. This decentralization of knowledge was accelerated by the printing press, which opened the doors to a dissemination of information on an unprecedented scale.

Ancient Greek empiricism, preserved as an incidental byproduct of European monastic transcription and Islamic scholarship, was finding a new audience amongst an emerging stratum of society eager for practical knowledge. An ascendant entrepreneurial class,  unshackled from centuries of feudal constraints, found its interests increasingly served by empirical proofs over appeals to authority. To that end, military competition amongst rival European powers had created a practical need for what we would now call ‘Research and Development’, entailing a far more rigorous approach for how ideas are tested against reality.

In sum: it would be a mistake to think of the development of science as inevitable. Quite the contrary: it was driven by practical problems which emerged due to a convergence of historical contingencies. The impetus behind the invention of science can be traced to limitations of early empiricism, which was proving inadequate as the problems it was applied to became increasingly complex. The crux of these shortcomings is that pre-scientific empiricism was calibrated to search for patterns of relevance within our person-sized mesoscale. In itself, there’s nothing surprising in this limitation, since the mesoscale is the obvious place to begin probing for clues in lieu of additional information that points elsewhere. 

But lest we paint a misleading picture, let’s make sure to give early-empiricism its due before moving forward; for it was able to accomplish quite a lot within this narrow, person-sized slice of reality. Beyond setting the stage for modern science, its success in probing this everyday domain brought us the principles behind many ideas and technologies that we still rely upon today. Agriculture, mathematics, navigation, and wheeled transport are testaments to this legacy. 

These noteworthy achievements notwithstanding, compared to its later scientific variant, the scope of problems that early empiricism was effective for was reaching a perceptual ceiling. The crux of the matter is that there’s nothing inherently special about the mesoscale, beyond the fact that it’s what our perceptual system and intuitions are calibrated for. And as we’ve seen, what affects us on the mesoscale can have explanations that are invisible to us from this perceptual default. 

And with that, we wrap this lightning tour of the historically contingent origins of modern science. As we’ve seen, empiricism was a notable expansion in our problem-solving repertoire, applicable to a host of day-to-day domains. But it would pale in comparison to the profound shift that occurred as the scientific method emerged. As we’ll see, its unprecedented operational success in transforming virtually every aspect of daily life would inadvertently birth a strange metamorphosis. What began as a more rigorous iteration of empiricism would be gobbled up, bit by bit, by tacit Transcendental assumptions that are outside of what science itself can provide evidence for. In our next section, we'll pull back this veil of scientific realism to reveal the more nuanced relationship between our models and the Reality they approximate.
