Abstract

Scale Theory embodies its title in every possible way. It offers both a deep dive into and a 10,000-foot view of scale, scalar thinking, and the role of scale in scientific inquiry. The subtitle, A Nondisciplinary Inquiry, is no less apt. Author Joshua DiCaglio blends insights from rhetoric, philosophy, literary studies, and mysticism to create a novel account of scalar thinking. In so doing, he weaves together detailed thought experiments, the work of Gregory Bateson, and Philip K. Dick’s account of an extraterrestrial communication he received while under the influence of anesthesia. Provocatively, Scale Theory treats these diverse intellectual resources as coequal contributors to an emerging theory of scale and scalar thinking. Within this nondisciplinary framework, the book is devoted to advancing two primary theses: (1) Notions of scale are undertheorized in science studies and related strands of new materialisms; and (2) Proper attention to questions of scale within these theoretical traditions should prompt a more thoughtful reconsideration of the merits of mystic holism. Ultimately, Scale Theory makes a compelling case for the first thesis and advances inquiry usefully in this area. With respect to the second thesis, DiCaglio refers to a certain academic “allergy” to holism (99), and I must confess I share this allergy. That said, I assume readers already predisposed favorably toward mystic holism are likely to find Scale Theory’s attention to the second thesis thoughtful and engaging.Scale Theory is organized into three distinct parts. Part 1, “Algorithms for a Theory of Scale,” presents three interrelated thought experiments that call upon readers to imagine themselves at various distances and vantage points with respect to several objects of interest. Part 1 is stylistically Wittgensteinian. Like the Tractatus-Logico Philosophicus (Wittgenstein 2013) or Latour’s “Irreductions,” (1993), the thought experiments unfold as a series of numbered and nested propositions, each postulating or interrogating an emerging concept in DiCaglio’s theory of scale. Part 2, “Configurations for a Theory of Scale,” returns the reader to more familiar styles of prose, providing a sort of review of the relevant literature and its relationship to the insights of the thought experiments. Finally, part 3, “Rhetorical Technologies for a Theory of Scale,” reflects on the twin marginalizations of rhetoric and mysticism in mainstream Western academia and argues for a new embrace of disembodied inquiry.The aforementioned thought experiments of part 1 outline DiCaglio’s theories of scale, scalar thinking, and scalar analysis. The discussion makes extensive use of visual and cinematic metaphors to aid the reader’s consideration of scalar questions. Ultimately, DiCaglio posits that scale is a function of the relationship between the “‘being’ of phenomena” and “the one who is measuring” (8). He argues, therefore, that “scale functions at a level above ontology and epistemology: scale is a means of orienting yourself both to experience and the being of things” (8). In making this argument, Scale Theory reflects on a range of scientific practices that require gradients of scale. Microscopy, telescopy, and simulations all provide scientists with tools to escape the mundane scales of embodied human experience. DiCaglio argues that “science must always find itself grouping things together, speaking of species, types, systems, and so on which exist on a different logical type than the individual encounters that make up these groups” (41). The taxonomic activities of scientific practice require shifts in scale to account for kingdoms, phyla, orders, genera, species, and all manner of nonbiological analogs.Within this framework, scale functions as a sort of meta-ontology that allows objects to be provisionally identified and delineated. Echoing Bateson, DiCaglio argues that In order for any thing to be said to exist whatsoever, a differential must exist out of which a difference can be discerned. Every differential occurs on some scale at which a fluctuation or movement is able to make a difference. If one goes to a smaller scale, any given differential is no longer able to be used to register a difference. (51)Thus, any given object only exists at certain scales where differences can be said to make a difference, and any given object also ceases to be an object at higher or lower orders where the differences no longer make differences. DiCaglio leverages the notion of “stability” or “stabilization” to refer to an object’s coming into being at any given scale. The metaphor of photographic or cinematographic “resolution” underwrites DiCaglio’s thinking in this area. Objects stabilize when they resolve relative to an observer’s perspective. While I find this account of stability thoughtful and compelling, it is somewhat unfortunate that it is so beholden to visual metaphors. Humans engage the world through many different senses, and not all humans engage the world with all senses.With his foundational ontology of scale established, DiCaglio proceeds to introduce “scalar analysis,” an approach to reckoning with objects, stability, and systems. The exploration of scalar analysis centers on a series of nested thought experiences and most prominently on a root cause analysis of a disease. Through oscillating our perspective between the whole human body and DNA mutations, DiCaglio shows how the dialectic of “zoom level” and “resolution” can further the analysis of complex systems. This analysis is engaging in many ways but suffers somewhat when addressing temporality. Scale analysis wants to “freeze time” (75) as an initial step, but then finds time “unwittingly introduced” (79) a few pages later. Ultimately, an analysis of causality in complex systems will probably require intentionally attending to the temporal dimensions. In fairness, at one point DiCaglio intentionally maps time to space (68) in an effort to maintain the visual metaphors of zoom and resolution. Indexing time to space is a common move, of course, and will likely only alienate a few passing Bergsonians.While the thought experiments in part 1 offer a number of interesting insights about scalar thinking, it is a bit troublesome that they exist almost exclusively in a vacuum. Aside from the occasional supportive reference to Bateson, part 1 is largely citation free. However, the insights provided seem linked in many important ways to prior efforts to understand complex systems and questions of scale. This includes both the work cited in part 2 and striking (albeit unexplored) parallels between scalar stability and accounts of stabilizing processes in the work of Alfred North Whitehead. The Whitehead parallel is, perhaps, not surprising given Bateson’s engagement with Whitehead and subsequent influence on Scale Theory. Nevertheless, this seems like an important connection and a missed opportunity. I would have very much enjoyed reading a discussion of this connection and/or an exploration of the potential synergies and disagreements between Scale Theory and Marilyn Cooper’s (2019) adaptation of Whitehead and Bateson for rhetorical new materialisms.That said, part 2 engages substantively with much of the related literature on new materialisms, actor-network theory, and cybernetics to explore previous attempts to grapple with many of the same issues of scale and complex systems. In so doing, Scale Theory argues that prior efforts to address these issues are hindered by undue focus on embodiment and embodied epistemology (in the case of feminist new materialisms), an inappropriate ontological flattening of scale (in actor-network theory), and lack of attention to holism (in cybernetics). With respect to feminist new materialisms, Scale Theory is particularly critical of Karen Barad and Donna Haraway. While I agree with DiCaglio that too much reliance on epistemology is a problem for some areas of new materialism, I am not sure epistemology is as prevalent in Meeting the Universe Halfway (Barad 2007) as DiCaglio suggests. Furthermore, I ultimately agree with Annmarie Mol who compellingly argues that the primarily problems of (post)modern epistemology come from the ways it is rooted in perspectivalism (2003). Thus, given the inherent perspectivism of scale theory, the approach may well replicate some of the issues new materialists most wish to avoid when avoiding epistemology in the first place.DiCaglio’s critique of embodied situated knowledges is ultimately anchored in his penchant for holism. He argues that bodies are properties of individuals, and that they situate perspective in that individual, atomistic perspective. In so doing, he critiques Haraway’s notion of situated knowledge for its overreliance on bodies that only exist at certain scales. As he writes, In scalar views there is something like a transcendent view that moves away from the body itself (2.10–12)1, zeros out the perspective as “mine” (2.9), and dislocates any single perspectival configuration. Thus, when Haraway declares that “feminists don’t need a doctrine of objectivity that promises transcendence” (579), we ought to hesitate. (134)Thus, to understand the universe, as DiCaglio hopes you will, is to shed your corporeal form and embrace some transcendental perspective. Again, my response to this is something like “yes and no.” I am on record agreeing that it is possible for a theory to be too embodied, although I don’t think this applies to Haraway. I have previously criticized some strains of affect theory for their excessive embrace of embodied experience (Graham 2016). Specifically, I argue that affect theory duplicates the problems of epistemology by positing a more authentic infralevel of embodied engagement that replicates the problematic perspectivalism on which (post)modern epistemology is built. The subject-object binary is replaced by a more privileged body-world binary. If this critique is correct (and I think it is), Scale Theory makes a similar error. Specifically, it inverts affect theory’s normative orientation, privileging instead a putatively “higher” level of unembodied binary engagement, a mind-universe binary, if you will.Scale Theory’s rejections of actor-network theory and cybernetics are similar in both tone and content to its rejections of situated knowledges. ANT and related strands of sociology and geography do not account for scale in quite the same way as Scale Theory’s opening thought experiments. Thus “this inability to handle scale confuses the terms at the outset” (162). Similarly, while cybernetics and systems theory have much to offer scale theory, they are ultimately treated as lacking since they don’t provide appropriate tools for appreciating the aggregation to unity. Channeling Lynn Margulis and James Lovelock, DiCaglio argues that while systems theory is useful for understanding bodies as ecologies, additional scalar (and perhaps mystical) elements are needed to pivot from bodies as ecologies to an apparently necessary identification of our equal oneness with bacteria and Gaia (173). Ultimately, part 2’s criticisms of prior efforts to address questions of scale proceed as though part 1 has successfully persuaded the reader on the merits of mystic holism. Part 2 takes the insights of the opening thought experiments as true, and recounts how feminist new materialisms, actor-network theory, and cybernetics fail to live up to the putative promises of scalar thinking. This is a risky rhetorical move, because for readers who are not entirely persuaded by the work of part 1, part 2 will come across as an exercise in somewhat uncharitable reading practices.Stepping away from the mysticism and my admitted allergies, Scale Theory also provides some thoughtful considerations on implications for rhetoric of science and science studies more broadly. As DiCaglio notes, “Because scale occurs outside of human experience, it must be re-presented at [human] scale. Inevitably, its representations will be partial and distorted” (183). Recognizing this fact points toward real challenges for scientific inquiry and scientific rhetoric which strives to account for notions of scale that cannot be contained at the scale of human representation. DiCaglio interrogates these challenges through an analysis of different modes of “specification” (193). When discussing specification, scholars of science studies most often consider what he dubs “ontological specifications”—that is, descriptions of objects, processes, and observed reality. We also (somewhat less regularly) attend to “epistemological specifications”—descriptions of knowing practices, sometimes methodology. But, since within scalar thinking, objects only exist at certain specific scales, neither ontological nor epistemological specification are sufficient to describe scientific activity. “Scalar specification” then becomes an essential additional rhetoric for both science and science studies. But scalar specifications are not without challenges.Here, DiCaglio draws our attention to “scale tricks” (228). Since scale must be re-presented, scalar thinking and scalar specifications may mislead readers through rendering scale invisible, presuming it infinite, or blending scales without acknowledging that they have been blended. For DiCaglio, transcending scale tricks is a question of accountability (231). Authors of re-presentations of experience have a duty to be consistent and precise in their scalar specifications. Precise specifications disrupt the potential confusions of scale tricks by making the scale intelligible, reminding readers or auditors that there is a scale, and preventing distortion through blending of scales. In some ways, DiCaglio’s theory of scalar specifications is a more encompassing version of the ethics of information design. Properly labeled x and y axes are critical to effective and ethical communication of charted data. Scale Theory reminds us that data need not be displayed graphically to be subject to scale and to require scalar specifications for interpretation.Part 3 of Scale Theory is devoted to the cosmos seeing itself. That is, it ruminates on possibilities for transcending corporality so as to achieve a perspective that all but transcends scale itself. DiCaglio does not precisely recommend specific techniques to achieve this transcendence, but he does point toward accounts of others that prominently feature hallucinogens, meditative practices, and methodical introspection. I will admit I find myself somewhat mystified by the mysticism that closes Scale Theory. Ultimately, I am pragmatic about theory. For me the utility of a theory lies in what work it does for inquiry, and that work needs to be indexed to a particular task at hand. Scale Theory might, perhaps, be considered pragmatic in this way, but the overriding task at hand is to understand the oneness of the universe. My scholarly aims are rather more modest. I put theory to work in an effort to address much more local tasks. As such, what I can take from Scale Theory for my own work may be more limited than what other readers can take. If you lack my allergy to holism and see the intersection of rhetoric, philosophy, and drug-assisted disembodied consciousness as a potential pathway to universal understanding, then this may well be the book for you. Even so, if your aims are somewhat more modest (like mine), then there is still much of interest in the pages of Scale Theory. DiCaglio adds important new dimensions of analysis to new materialisms and related science studies. Readers might take these dimensions as intended, but I would argue that they are also flexible enough to be read more synergistically alongside Cooper and Whitehead or Barad, Mol, and Haraway. And even if you reject new materialisms entirely, Scale Theory compellingly argues that rhetoricians of science would do well to attend, in more detail, to scalar specifications and the problem of scale tricks.
