Further Notes on Inspiration

Part 1: Response to Nick’s Comments

It is a rare and genuine pleasure for a writer to encounter a reader who not only engages deeply with the text but actively perceives the negative space around it, identifying the structural load-bearing concepts that are missing. Nick, your commentary on “From the Muses to the Mind: A Genealogy of Inspiration” is incisive, philosophically astute, and entirely fair. You have identified two major omissions in the genealogy, alongside a vital theoretical clarification regarding the contemporary psychology of inspiration.

In the spirit of collegial philosophical inquiry, I want to engage with your critiques on their merits. Where you are right—and you largely are—I will openly concede the gaps in the original essay and attempt to supply the supplementary thinking that should have been there from the start.

Point 1: The Omission of Socrates’ Daimonion

You first observe that the essay contains no discussion of Socrates’ daimonion (the divine sign or inner voice), and you imply that this is a significant gap in the historical arc. You are absolutely correct. In our eagerness to trace the lineage of theia mania (divine madness) from Plato’s Ion and Phaedrus down to the Romantics, the essay entirely bypassed the Apology, the Theaetetus, and Xenophon’s Memorabilia, effectively ignoring the other, parallel model of divine intervention in classical antiquity. This was a theoretical miss.

To understand why the daimonion is so crucial to a genealogy of inspiration, we must first recognize how radically it differs from the ecstatic possession of the Muses. The daimonion was Socrates’ private, interior divine sign (semeion). According to Plato’s Apology, Socrates experienced this phenomenon from childhood. At 31d, he describes it as a kind of voice that opposes him when he is about to act wrongly but never urges him toward positive action (Plato, Apology 31c–d, trans. Grube, in Cooper 1997, 28). Xenophon corroborates this account but gives the sign a somewhat broader scope, suggesting it could also offer positive guidance to Socrates and, through him, to his associates (Memorabilia 1.1.2–4; see McPherran 1996, 185–188).

This introduces three radical departures from the theia mania model of inspiration. First, the daimonion is fundamentally negative or prohibitive. Where the Muse is generative and protreptic—breathing a song into the poet and compelling him to sing—the daimonion is apotreptic; it checks action. It says “don’t” rather than “do.” Second, it is highly personalized and interior. The Muses were public deities invoked in civic and ritual contexts; Socrates’ sign was an intimate, lifelong companion that spoke only to him, operating at the threshold of what we would now call individual conscience. Third, and perhaps most importantly, the daimonion is non-ecstatic and rational-adjacent. When the poet is possessed by the Muse, he is, in Plato’s phrase, ekphron—out of his mind (Phaedrus 245a; Ion 534b). When Socrates hears his daimonion, he does not lose his senses; rather, the divine voice acts as an epistemic boundary condition, halting him so that his waking, conscious reason can re-evaluate the situation.

I should acknowledge, however, that the scholarly landscape around the daimonion is considerably more contested than my summary here suggests. Gregory Vlastos (1991, 280–287) interpreted the sign as a form of genuine divination whose authority Socrates accepted on faith, while Brickhouse and Smith (1994, 189–199) argued that it functions as a species of divine revelation consistent with Socratic epistemology. Others, including McPherran (1996, 175–210), have treated it as a proto-rational intuition whose divine framing reflects Socrates’ sincere religious commitments rather than a supernatural claim. These scholarly disagreements matter because they affect how we position the daimonion within a genealogy of interiority: is it an early rationalization of divine guidance, or a genuinely religious experience that merely looks like proto-rationality from our modern vantage point? The honest answer is that the texts underdetermine the question, and a complete genealogy would need to register this ambiguity rather than resolve it prematurely.

What would the inclusion of the daimonion have added to the essay’s genealogy? It would have provided the missing evolutionary link between the externalized divine agency of the archaic period and the internalized moral and creative faculties of the medieval and modern periods. The daimonion represents the earliest and most famous philosophical internalization of divine guidance. As Charles Taylor has argued in his monumental genealogy of moral sources, the trajectory from Platonic and Augustinian interiority through the Protestant conscience to the Romantic notion of inner creative genius represents a single, traceable arc of progressive internalization (Taylor 1989, 127–142). The daimonion belongs near the origin of that arc. By omitting Socrates’ prohibitive inner voice, the essay presented the internalization of the Muse as a predominantly Enlightenment and Romantic achievement, whereas the seeds of that interiority were already planted in the trial of Socrates (Taylor 1989, 115–121). I concede this gap entirely; the genealogy is incomplete without it.

Point 2: Thrash as the “Darwin of Cultural Evolution”

Your second critique addresses the essay’s treatment of the contemporary empirical psychology of inspiration, specifically the work of Todd M. Thrash. You argue that the essay missed Thrash’s most revolutionary contribution: the thesis that inspiration is fundamentally a mechanism of cultural evolution, and that the essay’s conclusion sells his theory short as a result.

You frame Thrash as “the Darwin of cultural evolution,” and you provide a series of striking quotations from his work to support this reading. These appear to be drawn from Thrash’s late-career theoretical synthesis, which exists in manuscript or preprint form and which I have been unable to verify in a standard peer-reviewed venue. I present them here as Nick reported them, attributed to Thrash’s unpublished synthesis on cultural evolution (Thrash, n.d., unpublished manuscript):

• “Humans evolved to be transmitters of culture, and inspiration marks the full functioning of the cultural creature.”
• “Inspiration, I argue, is a genetically evolved adaptation that catalyzes and guides cultural evolution…”
• “Inspiration marks the recruitment of human psychological resources in service of cultural evolution.”
• “The best thought leader is the best thought follower, heir to the evolving cultural tradition and evolver of it.”

This is a profound critique, and I must concede it directly. The original essay focused almost exclusively on the phenomenology of Thrash and Elliot’s tripartite model (evocation, transcendence, approach motivation) and its neuroscientific correlates (see, e.g., Jung-Beeman et al. 2004 on coarse semantic coding; Kounios and Beeman 2014 on alpha-band gating). In doing so, it treated modern psychology merely as a secular vocabulary for describing the experience of inspiration. What the essay missed was Thrash’s teleology: his explanation of why this psychological mechanism exists in the first place.

If we take Thrash’s cultural evolution argument in its strongest form, culture itself is the “muse.” Human beings are not merely problem-solving engines; we are biologically primed by our evolutionary history and culturally primed by our upbringing to be sensitive to specific evocative objects, ideas, or paradigms. When we encounter an idea of exceptional worth, the state of inspiration is triggered. This state is not a mystical accident; it is, in Thrash’s framing, a “genetically evolved adaptation” (Thrash, n.d., unpublished manuscript). It temporarily suspends our mundane, ego-driven goals (the “transcendence” and passivity noted in the essay) and recruits our psychological and metabolic resources to transmit, refine, or actualize that cultural artifact (the “approach motivation”).

In this light, the inspired individual is a transmitting agent in a grand process of cultural selection. Just as genetic evolution relies on biological reproduction to pass on adaptive traits, cultural evolution—on Thrash’s account—relies on the psychological state of inspiration to ensure that the most valuable, beautiful, or useful ideas survive and propagate across generations. The mediational model presented in Thrash et al. (2010, 469–471) establishes the empirical groundwork for this claim, showing that inspiration mediates between the initial creative idea and its ultimate actualization, though the stronger evolutionary-adaptation framing appears to be developed most fully in the later, unpublished synthesis. Your quote—“The best thought leader is the best thought follower”—perfectly encapsulates this paradox. One must be a receptive follower of the cultural tradition in order to be moved by it, and only by being moved by it can one lead its next evolutionary step.

This reframing is significant because it moves inspiration out of the realm of mere individual psychological quirk and into the realm of biological and cultural function. I accept your critique that the essay’s conclusion undersold this. However, I will offer one philosophical complication—not to push back against Thrash’s brilliance, but to defend the essay’s concluding gesture toward mystery. Thrash’s evolutionary account operates at the level of distal causation (why the trait evolved), whereas the essay’s conclusion was primarily concerned with proximate phenomenology (what it is like to experience it). These two explanatory levels are, in principle, compatible: a Darwinian explanation of why we feel hunger does not eliminate the subjective experience of hunger. Yet there is a genuine tension point worth naming. Does knowing that the feeling of being “seized” by an idea is an evolved adaptation for cultural transmission alter the phenomenology for the knowing subject? Philosophical defenders of strong cognitive penetration (e.g., Siegel 2010) might argue that background beliefs can reshape perceptual and affective experience, in which case understanding the evolutionary story could subtly deflate the felt transcendence of the inspired state. Conversely, if inspiration’s phenomenology is generated by rapid, automatic subcortical and default-network processes (Beaty et al. 2016), it may be largely impervious to top-down reframing. I do not resolve this here, but I note that the compatibility of distal and proximate accounts cannot simply be assumed; it must be argued for. Nevertheless, you are entirely correct that omitting the evolutionary function of this passivity leaves the contemporary portrait of inspiration half-drawn.

Point 3: Inspiration Does Not Create the Artifact

Your final point is perhaps the most conceptually disruptive. You note that Thrash makes a counterintuitive and historically radical claim: inspiration is not the creative act itself. In Thrash’s model, the creative artifact (or the seminal idea) comes first—often produced through ordinary, uninspired cognitive work, associative thinking, or by encountering someone else’s work. Then, we are inspired by it. Inspiration does not generate the artifact; rather, it registers the worth or value of the artifact in the eyes of the subject, compelling them to bring it to fruition.

This is a brilliant and necessary clarification, and it exposes a latent conflation in the original essay. For millennia, the Western tradition implicitly treated inspiration as upstream of the creative act. The Muse breathes the song into the poet, and the song is the result. The Holy Spirit illumines the prophet, and the prophecy is the result. The original essay, particularly in Section V, implicitly perpetuated this causal assumption by blurring the lines between “insight” (the cognitive generation of an idea, the “Aha!” moment) and “inspiration” (the motivational response).

Thrash’s model reverses this causal arrow in the paradigmatic case. As he and his colleagues have demonstrated, inspiration is fundamentally responsive, not generative: the tripartite model’s “evocation” component requires an elicitor object, meaning one is always “inspired by” something (Thrash and Elliot 2004, 957–959). The idea flashes into the mind—perhaps through the right-hemisphere coarse-coding and alpha-gating mechanisms discussed in the essay (Jung-Beeman et al. 2004; Kounios and Beeman 2014)—but that cognitive insight is not yet inspiration. Inspiration is the subsequent, overwhelming recognition of the intrinsic value of that insight, which then serves as a transmission channel linking the external stimulus to approach motivation (Thrash et al. 2010, 470–471).

I should add a necessary qualification here. To say that Thrash “reverses” the causal arrow is to describe the paradigmatic or modal case within his framework. Thrash and his colleagues acknowledge that creative ideation and inspirational response can be temporally intertwined in practice—that inspiration can feed back into further ideation in a recursive loop (Thrash et al. 2010, 483). The strong claim is not that inspiration never co-occurs with or contributes to ideation, but that conceptually and typically, inspiration is a response to perceived value rather than a generator of content. This is a distinction of theoretical architecture, not an absolute temporal sequencing claim.

To put it in the terms of the essay: inspiration does not write the poem; inspiration is the psychological fire that makes the poet realize the poem is worth writing, and provides the sustained, transcendent energy to execute the labor of writing it. It is the perception of value, not the generation of content.

This overturns the traditional causal story in a way that the original essay failed to articulate. If inspiration is the responsive recognition of value rather than the generative source of the idea, then the ancient tension between “gift” and “craft” (discussed in Sections I and II) is resolved in an entirely new way. Craft, incubation, and ordinary cognition generate the raw material; the “gift” is the sudden, involuntary psychological awakening to the ultimate worth of that material, which recruits the human organism to serve as its cultural transmitter.

Nick, your interventions have not merely added detail to this genealogy; they have corrected its trajectory. By reintroducing the prohibitive interiority of the daimonion, foregrounding the evolutionary function of cultural transmission, and clarifying the responsive rather than generative nature of the inspired state, you have helped produce a far more robust philosophy of mind. Part 2 of this document shifts register entirely: it presents a freestanding philosophical argument—a deflationary case that inspiration is a difference of degree rather than kind—which stands in productive tension with the genealogy and with Thrash’s framework alike.

Part 2: Inspiration as Difference in Degree, Not Kind

There is a widely shared intuition that inspiration represents the absolute peak of human cognitive and creative experience. Phenomenologically, an inspired idea feels singularly momentous, carrying a weight and a luminosity that seem to set it apart from the mundane stream of consciousness. Furthermore, communicating an inspired idea to others—whether or not those others are immediately receptive—often intensifies its perceived value, cementing its status as an extraordinary mental event. This intuition is powerful and culturally pervasive. However, acknowledging the profound experiential weight of inspiration does not require conceding that it constitutes a genuinely distinct psychological phenomenon. The deflating argument that follows is not a dismissal of inspiration’s importance, nor a denial of the value of great ideas. Rather, it is a philosophical reckoning with whether inspiration warrants classification as a distinct natural kind. Upon rigorous examination, inspiration is revealed not as a discrete psychological category, but merely as a linguistic label applied to the extreme high end of ordinary cognitive continua.

To understand how inspiration is mistakenly categorized as a unique phenomenon, one must first examine the folk psychological model that purportedly distinguishes it from ordinary ideation. In common parlance, inspiration is characterized by three defining traits. First is suddenness or unbiddenness: the idea arrives unwilled, without deliberate, conscious effort. Second is surprise: the content of the idea feels as though it exceeds what one expects from one’s ordinary capacities, arriving with a sense of transcendent alterity. Third is motivation toward action: the idea actively impels the subject to realize, pursue, or communicate it.

It is crucial here to distinguish suddenness from surprise, as the two are frequently conflated. Suddenness refers merely to the temporal and causal mechanics of an idea’s arrival; an idea can arrive suddenly without being surprising. A mundane childhood memory surfacing from nowhere, or the sudden realization that one forgot to lock the front door, arrives completely unbidden, yet it draws upon entirely familiar cognitive capacities. Surprise, by contrast, refers specifically to the content of the idea feeling beyond one’s usual range or standard generative abilities. This distinction is vital for the deflationary critique that follows.

This folk tripartite model has been formalized in contemporary psychology, most notably by Todd M. Thrash and Andrew J. Elliot. In their effort to operationalize inspiration as a rigorously measurable psychological construct, Thrash and Elliot (2003, 871–873; 2004, 957–959) identify three core characteristics: evocation, transcendence, and approach motivation. This scientific model maps onto the folk scheme in instructive ways. Evocation corresponds to suddenness and unbiddenness; the individual is “seized” by an idea rather than having willed it. Transcendence corresponds to surprise; it is the sense of awakening to something better, higher, or beyond one’s ordinary self-concept. Approach motivation corresponds to the impulse toward action; it is the drive to actualize or express the evocative vision. To their credit, Thrash and Elliot treat these as analytically separable components rather than a fused gestalt, which means their model already partially anticipates the kind of decompositional analysis offered here. The deflationary question, however, is not whether the components can be separated analytically, but whether their conjunction picks out a genuine natural kind—a psychological category that carves cognition at its joints—or whether it merely clusters features that are individually continuous with ordinary mental life. Thrash has built a substantial research program on this foundation, framing inspiration as a historically neglected force in psychology and characterizing it as a vital mechanism of cultural evolution (Thrash et al. 2010, 469–471; Thrash, n.d., unpublished manuscript).

However, when each of these three characteristics is subjected to critical scrutiny, none proves distinctive to inspiration.

First, suddenness and unbiddenness are in no way unique to inspired states. Cognitive psychology has long established that spontaneous thought is a pervasive, baseline feature of human mental life. The landmark experience-sampling study by Killingsworth and Gilbert (2010) found that people’s minds wander during roughly 46.9% of their waking hours, a figure subsequently supported by a broad research literature on task-unrelated thought (Christoff et al. 2016, 718–720). More recent work has further demonstrated that spontaneous thought is not a monolithic phenomenon but separates into distinct clusters of negative, positive, and flexible mentation (Migó et al. 2025). Ordinary thoughts, trivial memories, and mundane realizations arrive just as suddenly and unbidden as paradigm-shifting epiphanies. The suddenness of an idea is a ubiquitous feature of associative cognition, not a marker of a special class of experience.

Second, surprise—or transcendence—is not a necessary condition for great ideas, nor is it absent from trivial ones. The history of creativity research demonstrates that many profound ideas grow gradually, revealing their significance over time without any dramatic, sudden dawning. As Robert Weisberg (2006, 56–89) has argued in his sustained critique of “genius myths,” canonical creative achievements in science and the arts typically emerge through incremental problem-solving, deliberate practice, and iterative refinement rather than through moments of transcendent revelation. Dean Keith Simonton’s (1999, 24–47) historiometric analyses similarly show that creative productivity is better predicted by sustained output and domain immersion than by discrete moments of sudden illumination. An individual can recognize the immense power of an idea without it ever feeling alien or beyond their usual capacities; the significance simply accumulates quietly through iterative work. Furthermore, recognition is often an iterative process. One may need to encounter or manipulate an idea multiple times before its full dimensions and significance become apparent. If an idea can be monumental without being surprising, and if its recognition can be iterative rather than instantaneous, then surprise is neither universal to inspiration nor absent from ordinary ideation.

The question naturally arises: does Thrash’s own empirical data show that reports of high inspiration always co-occur with high transcendence scores? Notably, while the three components of the Inspiration Scale tend to correlate positively, they are measured as separable dimensions, and individual response profiles can and do diverge. A person may score high on approach motivation and evocation while reporting relatively modest transcendence (Thrash and Elliot 2003, 879–882). This internal variability within Thrash’s own psychometric instrument suggests that the supposed unity of the “inspiration” construct is looser than the theoretical framing implies.

The feeling of transcendence is, moreover, partly a historical artifact of the concept’s genealogy. Inspiration was originally understood in antiquity as literally divine in origin—a theia mania or possession by the Muses, as Plato describes in the Ion (533d–534e) and the Phaedrus (245a; see also Dodds 1951, 64–82; Tigerstedt 1969, 13–35). During the Enlightenment, a massive semantic shift occurred. Edward Young, in his Conjectures on Original Composition (1759), argued that true genius operates through spontaneous “vegetable” growth from within rather than through the mechanical imitation of classical models, effectively relocating the source of creative power from divine gift to innate nature. Immanuel Kant formalized this move in the Critique of the Power of Judgment, defining genius as “the talent (natural endowment) that gives the rule to art” and insisting that the genius himself “cannot describe or indicate scientifically how he brings about his products” (Kant 1790/2000, §46, 186–187). These thinkers naturalized inspiration, relocating its source from the heavens to the innate, albeit opaque, faculties of human cognition.

However, it must be conceded that this genealogical observation about the concept does not, by itself, debunk the phenomenology. Even if the word “transcendence” carries theological residue, the feeling of being surprised by one’s own cognitive products could have independent psychological causes. Ap Dijksterhuis and Loran Nordgren’s (2006) unconscious thought theory, for instance, proposes that complex decisions and creative products are often generated by unconscious deliberation whose outputs arrive in consciousness with an air of novelty precisely because their generative process was inaccessible. On this account, the feeling of transcendence is real but explicable: it is the phenomenological signature of unconscious processing delivering its results to conscious awareness. Crucially, this mechanism is continuous with ordinary cognition—unconscious processing underlies mundane decisions as well as extraordinary ones. The feeling of transcendence thus reflects a structural feature of the conscious/unconscious interface, not a special category of experience. Lisa Feldman Barrett’s (2017, 30–55) theory of constructed emotion offers a complementary perspective: affective experiences, including the feeling of being “seized” or “elevated,” are actively constructed by the brain using prior conceptual categories, which means that a culture steeped in the mythology of inspiration will construct the affective experience of transcendence more readily and more vividly. The phenomenology is real, but it is continuous with the construction of all affective states, not evidence of a discrete psychological kind.

Third, motivation toward action is not a distinctive feature of inspiration. Ordinary, mundane thoughts routinely prompt behavioral realignment and reorientation. The sudden realization that it is raining motivates one to grab an umbrella; the thought of an upcoming deadline motivates one to begin working. These are approach motivations, yet they do not qualify as inspiration. A defender of Thrash’s framework would rightly object that the relevant approach motivation is not any motivation but specifically motivation triggered by evocation and accompanied by transcendence—that is, the three components must co-occur. This objection has force, but it merely relocates the problem rather than solving it. If the distinctiveness of “inspirational” motivation depends entirely on its conjunction with evocation and transcendence, and if evocation and transcendence have been shown to be continuous with ordinary cognitive processes, then the conjunction itself is continuous with ordinary cognitive life. A conjunction of non-distinctive features does not automatically produce a distinctive kind; it produces a region of a multidimensional continuum.

Furthermore, realized action or creative output is not a necessary condition for an idea to be deeply motivating. An individual can experience a profound, highly motivating idea but be entirely prevented from acting upon it by external constraints, such as coercion or lack of resources, or by internal constraints, such as depression, anxiety, or deficits in executive function. Research on executive function and self-regulation has repeatedly demonstrated that strong internal intentions can be severed from behavioral execution by impairments in inhibitory control, working memory, or cognitive flexibility (Diamond 2013, 135–141; Hofmann, Schmeichel, and Baddeley 2012, 174–180). What matters for the classification of an idea’s power is the strength and depth of the motivational registration, not its successful completion. Because ordinary ideas motivate action, and because inspired ideas can fail to result in action, approach motivation cannot serve as the boundary line for a distinct psychological kind.

Once these supposedly distinguishing features—unbiddenness, surprise, and motivation—are stripped of their mystique, none turns out to be unique to inspiration. Each characteristic is entirely continuous with the mechanics of ordinary ideation. What exists instead is a continuum. The key variable is simply how good and significant an idea is, which correlates predictably with the strength of the impulse to realize it. A moderately good idea generates moderate motivation; a truly great idea generates intense motivation. Inspiration does not exist in a separate, discrete category; it merely sits at the extreme high end of this continuum.

In the philosophy of mind and the philosophy of science, a fundamental distinction is drawn between “natural kinds”—categories that carve nature at its joints and exist independently of human convention—and merely nominal or conventional classifications. The homeostatic property cluster account of natural kinds, as developed by Richard Boyd (1991, 127–141), holds that a natural kind is constituted by a cluster of properties that reliably co-occur because of some underlying causal mechanism. The deflationary argument here is that no such mechanism has been identified for “inspiration” that is not already operative in ordinary cognition. The co-occurrence of unbiddenness, felt significance, and motivation is explained by the general architecture of associative memory, salience detection, and goal-directed behavior—mechanisms that underlie all ideation, not a privileged subset of it. Ian Hacking’s (1991) analysis of the social construction of scientific categories offers a complementary warning: some categories that appear to carve nature at its joints are in fact products of classificatory practices that create the phenomena they purport to discover. “Inspiration” may be such a category—a folk-psychological and cultural label that, once formalized into a psychometric construct, generates the appearance of a distinct phenomenon through the very act of measurement.

This realization has profound implications for Thrash’s project and the broader empirical study of inspiration. Framing inspiration as a neglected topic that requires its own dedicated psychological subfield is an instance of reification—what Alfred North Whitehead (1925, 51) termed the “fallacy of misplaced concreteness.” Whitehead coined this phrase to describe the error of treating abstractions as though they are concrete, independently existing entities. The related philosophical concept of hypostatization—treating a process, relation, or quality as a substance—captures the same error from a different angle. Thrash and his colleagues have taken the word “inspiration”—a cultural and linguistic label applied to the high end of familiar continua—and treated it as though it picks out a distinct psychological natural kind.

In reality, the phenomena that Thrash attributes to inspiration are already exhaustively covered by existing, robust psychological research programs. The unbidden arrival of ideas is the domain of spontaneous cognition and memory retrieval. The quality and novelty of ideas are the domain of creativity and insight research. The drive to actualize an idea is the domain of motivational psychology and executive function. There is no hidden phenomenon here that existing psychology has overlooked; there is only a familiar cluster of cognitive and affective responses that has been given a poetic name and subsequently treated as if the name referred to a novel discovery.

Consequently, Thrash’s empirical findings do not disappear, but their theoretical significance is radically reframed. His psychometric scales are not measuring a unique psychological state; they are measuring the high end of familiar continua—of ideational quality, of motivational registration, and of felt significance. The grand claim that inspiration is “the driver of cultural evolution” is therefore deeply undercut. It is undercut not by denying that great ideas matter—they obviously do—but by denying that the label “inspiration” identifies a unique mechanism of cultural selection. It is not “inspiration” that drives cultural evolution; it is simply really good ideas, and the perfectly ordinary motivational systems that respond to them.

Ultimately, this deflationary account is not a pessimistic outcome, nor does it render human creativity mundane. It simply removes a categorical distinction that was never coherently motivated by the evidence. If the features of inspiration are entirely continuous with ordinary ideation, then every good idea, every sudden realization, and every creative impulse participates, however modestly, in the exact same cognitive architecture that produces humanity’s greatest achievements. By dissolving the artificial boundary between the ordinary and the inspired, the phenomenon of inspiration is not diminished; rather, it is distributed. The reification has been identified and discarded, leaving behind not a mystical visitation or a discrete psychological anomaly, but a well-populated, scientifically intelligible continuum of human thought at its best.
