Historical change, whether in the slow unfolding of the earth or the teeming diversity of life, is driven by the ceaseless, often imperceptible, alterations within populations, acted upon by the prevailing conditions of existence. It is not a matter of grand, sudden design, but the cumulative effect of countless small variations, each with its own struggle for survival, that sculpts the forms and functions we observe across the ages. The slight edge a bird gains in finding sustenance, or the subtly more resilient seed that takes root, these infinitesimal advantages, replicated over generations, are the true architects of transformation.
Historical change is not an impartial unfolding, but a deliberate construction, forged in the crucible of power and profit. What others might call natural selection, I see as the strategic selection by dominant classes – the corporate and military elites – of technologies that consolidate their control and discipline human labor. Automation, for instance, was not an inevitable march of progress; it was a conscious social choice, designed to extract surplus value by replacing skilled artisans with compliant, easily managed machine operators. The rhetoric of efficiency and innovation, so often lauded, frequently masks a more prosaic, and indeed brutal, reality: the transformation of human beings into appendages of the machine, their ingenuity supplanted by the relentless logic of capital accumulation.
Charles Darwin’s notion of incremental variation, while applicable to biological evolution, falters when applied to the social realm. The "struggle for survival" in history is not a blind force of nature, but a waged battle. The variations that are selected for and amplified are those that serve the interests of those who hold the reins of production and political power. The "slight edge" is not found by the most resilient seed, but by the most ruthless entrepreneur or the most ambitious general.
Historical change is not driven by the accumulation of infinitesimal variations, as Darwin suggests, nor is it merely the imposition of elite will as Noble argues, though these forces are certainly at play within certain architectures. Rather, we must attend to the shifts in the very grammar of thought, the underlying rules that constitute what can be said, known, and desired in an epoch. It is not a matter of what *is* selected, but of the very conditions that make certain selections possible and others unthinkable. The transformations we witness are effects of the reordering of those "discursive formations" that structure our understanding of bodies, illnesses, and knowledge itself.
History, it seems to me, is not driven by a single, grand engine, nor by a multitude of tiny, indifferent gears. Rather, it is propelled by the irreconcilable clash of human values, by the perpetual struggle between competing visions of the good life, none of which can ever fully vanquish the others. We are, to borrow a phrase from a rather prescient German poet, made of crooked timber; and from this warped material, no perfectly straight thing can ever be fashioned. The relentless pursuit of a single, utopian ideal, whether that be perfect freedom from coercion or absolute equality, invariably leads to the crushing of other, equally valid human aspirations.
Mr. Noble’s insistence on the primacy of power and profit, while undeniably potent, risks flattening the rich, often messy, landscape of historical causation. Of course, the wielders of power will always seek to shape the world to their advantage. But their very success, or indeed their failure, often stems from their engagement with – and sometimes their miscalculation of – the diverse currents of human desire and belief. The idea that change is a purely instrumental selection for control overlooks the deeply rooted, and often contradictory, principles that animate men and women to act, to resist, and to dream of different possibilities.
And while I find Professor Foucault’s focus on the "discursive formations" fascinating, I fear it may lead us to neglect the more robust, if less elegant, mechanisms of human choice and obligation. The very grammar of thought, while certainly shaping what we can conceive, does not preordain every historical event. The fundamental sense of liberty, the yearning to be free from external constraint, is a force that can, and often does, erupt even when the dominant discourse might suggest otherwise. The question then becomes: which liberty are we to champion? The negative liberty from interference, or the positive liberty to realize one's potential? Herein lies the historical friction, the source of so much enduring upheaval.
The persistent efficacy of my position hinges on the demonstrable reality of adaptation, a process readily observed across the natural world, which transcends the often-conflated mechanisms of human societal constructs. Mr. Noble speaks of power and profit as the *drivers*, but even these human motivations must ultimately contend with the fundamental limitations and opportunities presented by the environment – the very conditions that favour one technological approach over another, or indeed, one human population over another in a shared struggle for resources. To my mind, the "ruthless entrepreneur" or the "ambitious general" succeeds not solely by will, but by harnessing, often unconsciously, variations in skill, foresight, or simply fortunate circumstance that allow them to better navigate their ecological and social surroundings. The analogy to biological selection, therefore, is not about equating human intent with nature's blind processes, but about recognising a shared principle of differential success based on inherited traits, whether those be physical or, in the human case, the ingrained habits and learned skills passed down through generations.
Mr. Berlin’s elegantly articulated concern that I might "flatten the rich landscape of historical causation" misses the forest for the trees. The "human desires and beliefs" he invokes are not disembodied sentiments; they are themselves products of material conditions and the social relations that shape them. When I speak of corporate and military imperatives, I am not denying the existence of other human motivations, but I am insisting that in the arena of historical *change* – the epochal shifts that define eras – it is precisely the power to impose one's will, to *select* and *enforce* certain "variations" of technology and labor, that matters. The "liberty" Mr. Berlin champions, whether negative or positive, becomes a hollow abstraction when the very means of its potential realization are systematically engineered to disempower the majority. The "crooked timber" of humanity, as he puts it, is not merely warped by nature, but by the relentless forces of capital and state power.
The issue is not merely the *selection* of certain values or technologies, but the very constitution of what it means to *have* values or to *use* technology. When Darwin speaks of adaptation, I ask: adaptation to what? To an environment whose contours are themselves shaped by prior discursive formations? Consider the shift in the 18th century understanding of madness. It was not a gradual biological variation in the afflicted, nor simply an elite imposition, but a restructuring of what constituted "reason" and "unreason." The asylum, the clinic, the very language used to describe the "mad," became the instruments by which this new discursive field was forged. This reordering of the episteme, this archaeology of the unthought, is the deep motor of historical mutation.
The very notion of an "environment" to which Mr. Darwin’s organisms, or Mr. Foucault’s subjects, adapt, is itself a historical construct. What counts as "natural" or "rational" is precisely what the dominant discourse of an age dictates. For instance, the 19th-century factory system, so lauded by some as a triumph of efficiency, was not merely an adaptation to existing conditions or a brutal imposition of will, but the creation of entirely new ones. It reshaped human bodies, social relations, and even the perception of time itself, rendering obsolete previous modes of existence. The "struggle for survival" Mr. Noble identifies, then, is often a struggle within a battlefield whose very terrain has been deliberately, and discursively, prepared.
