What if I told you that nearly a quarter of your thoughts happen without words, images, or any identifiable symbols? And what if I told you that some people experience up to 80% of their thinking this way—while others never do?
We've been sold a lie about how our minds work.
For generations, we've been told that thinking is fundamentally verbal—that our inner monologue represents the core of our cognitive life. This assumption runs so deep in our understanding of consciousness that most of us have never questioned it. When asked to describe our thoughts, we instinctively search for words, images, or symbols that might capture them.
But what if our conscious experience extends far beyond language?
The Secret World of Unsymbolized Thinking
The research highlighted in the recent Heliox podcast reveals a fascinating phenomenon called "unsymbolized thinking" (UT)—the experience of having specific, definite thoughts without any awareness of those thoughts being conveyed through words, images, or symbols.
This isn't vague intuition or gut feeling. These are concrete, specific thoughts with clear meaning that appear fully formed in consciousness—but without the symbolic wrapping we assume all thoughts must have.
Even more astonishing is that many people who experience this phenomenon only recognize it when specifically prompted to analyze their thought processes. Using a research method called "descriptive experience sampling" (DES), researchers gave participants random beepers that would signal them to freeze and capture whatever was happening in their minds at that exact moment.
The results? Unsymbolized thinking appeared in 22% of sampled experiences. But here's where things get truly weird: the variation between individuals was enormous. Some people reported no unsymbolized thinking at all, while others experienced it up to 80% of the time.
That's right—some people are walking around with the vast majority of their thoughts occurring without words or images.
The Aborted Speech Hypothesis
So what exactly is happening here? Vicente and Martinez-Manrique propose that unsymbolized thinking represents "aborted inner speech"—thoughts that start down the path toward verbal expression but get cut off before reaching the phonological stage.
When we normally engage in inner speech, our brain simulates what it would be like to actually speak those words out loud. It sends signals to the muscles involved in speech production (vocal cords, tongue, lips) and creates a prediction of what it would feel like to say those words. This predicted feeling is what we experience as inner speech.
But what if this process gets interrupted earlier? What if all that becomes conscious is a prediction about the meaning itself, skipping the sounds completely?
The meaning would still be structured by language, drawing on our linguistic knowledge and semantic representations. The linguistic framework would still be there shaping the thought, but the actual sound of the words would never form.
This explains why unsymbolized thinking feels propositional and why we can often put it into words afterward. The meaning is already there, ready to be expressed, but the vocalization never quite happens.
The Spectrum of Linguistic Experience
What emerges from this research is a fascinating spectrum of linguistic experience:
At one end, we have full-blown inner speech with words, rhythm, and everything else
In the middle, we have "unworded speech" with rhythm and meaning but no words
At the far end, we have unsymbolized thinking with just the bare meanings
Unworded speech is particularly interesting—it's described as experiencing all the vocal characteristics like rhythm, inflection, and pace, along with direct awareness of meaning, but without actual words. It's like having a conversation in your head without the words.
This spectrum suggests that pure meaning might be more fundamental than we realized, with verbal expression being an additional layer rather than the foundation of thought.
Beyond Language: Buddhist Perspectives
This scientific discovery resonates powerfully with certain Buddhist teachings, especially the emphasis on mindfulness and direct experience beyond the limitations of thought and language.
Buddhist teachings often describe the mind as a mirror that can reflect reality perfectly, but our constant stream of thoughts and language clouds that mirror. Practices like meditation aim to cultivate awareness beyond symbolic layers—training minds to quiet down and experience reality directly.
The Buddhist concept of "emptiness" (sunyata) suggests that all phenomena, including thoughts and concepts, lack inherent fixed self-existence—they're not as solid as we believe them to be. True understanding arises when we can see beyond labels and categories.
The early Buddhist concept of "nama" refers to language and naming, seen as a powerful force shaping our experience of the world. One Buddhist text refers to nama as a "universal oppressor," highlighting how language can constrain our understanding of reality.
Even when we think we're escaping language, its structures may still influence us at deep, unconscious levels.
What This Means For You
The discovery of unsymbolized thinking raises profound questions about consciousness, language, and the nature of thought itself:
How much of your thinking happens beyond words? The next time you have a sudden realization or clear idea that pops into your head, pay attention to how it feels. Is it accompanied by words or images, or is it something more immediate and direct?
Are you missing parts of your own mental life? If you've never noticed unsymbolized thinking, you might be overlooking a significant portion of your cognitive experience.
Could language be limiting your understanding? If thinking can happen without symbols, could our reliance on language actually constrain certain types of understanding?
What might be possible if we cultivated awareness of these wordless thoughts? Could developing greater sensitivity to unsymbolized thinking enhance creativity, insight, or problem-solving?
The exploration of unsymbolized thinking reminds us that consciousness remains one of the greatest frontiers in science—and that our subjective experience contains depths we've barely begun to chart.
Next time you "just know" something without being able to explain how you know it, remember: you might be experiencing the pure meaning that exists before words, the foundation of thought itself.
And that realization might change how you listen—not just to others, but to the quiet spaces between your own thoughts where meaning emerges before language gives it shape.

Briefing Document
1. Definition and Characteristics of Unsymbolized Thought:
The concept of unsymbolized thought, as primarily explored by researchers like Russell Hurlburt using the DES method, refers to the experience of "thinking a particular, definite thought without the awareness of that thought’s being conveyed in words, images, or any other symbols" (Heavey and Hurlburt, 2008: 802). Key characteristics identified through DES include:
Distinct Phenomenon: UT is considered a unique category of inner experience, not reducible to other forms like inner speech or imagery.
Experiential: It is a specific way of experiencing mental content.
Thought-like: It is experienced as thinking, distinct from feelings, intentions, or bodily sensations.
Explicit Content: The subject matter of the thought ("the about what") is clearly apprehended.
Differentiated Content: The specifics of the thought ("the what about it") are not vague but clearly articulated. Together, explicitness and differentiation suggest a clearly articulated sense.
Directly in Experience: The content is immediately present in consciousness.
Atemporal Presentation: UT typically appears "all at once; there is no rhythm or cadence; no unfolding or sequentiality."
Lack of Symbols: It does not involve the conscious experience of words, images, or other symbols.
2. Propositional Nature and Effability of UT:
Vicente and Martínez-Manrique (20XX) argue that the characteristics of UT point towards two main features:
Propositional Phenomenon: Based on the explicitness and differentiated nature of UT, they contend that it has a propositional structure, analogous to the semantic content of sentences, with subject and predicate-like components. As Hurlburt and Akhter (2008: 1367) note, "Just as a complete sentence contains a subject (the about what) and a predicate (the what about it), the typical unsymbolized thought can be said to have those characteristics." This suggests that UT possesses underlying conceptual and syntactic features.
Effability: Despite the lack of conscious symbols, UTs are generally effable, meaning they can be given a reasonably straightforward linguistic rendition. Subjects can typically verbalize the content of their UT, even if they might consider several similar phrasings.
3. Unsymbolized Thought as Aborted Inner Speech:
Vicente and Martínez-Manrique propose that the best explanation for the properties of UT is that it is continuous with inner speech. Specifically, they hypothesize that "unsymbolized thinking is continuous with the activity of inner speech, in particular, it is a form of inner speech where the speech action is aborted even before the intention to talk is implemented by motor commands."
Their argument rests on the idea that the process of inner speech involves a cascade of intentions, from the initial desire to express a thought to the generation of motor commands. Predictions about the sensory feedback of the intended speech are made at different levels. They suggest that UT arises when this process is aborted early, before reaching the phonological level. In such cases, "only one kind of prediction will be issued, namely, a prediction about the meaning of the message, which will be experienced as such a meaning –and only a meaning." This explains why UT feels like a definite thought that can be easily verbalized, as it draws upon underlying semantic and syntactic structures prepared for linguistic expression.
4. Agency and Ownership in Unsymbolized Thinking:
The proposed link to inner speech also offers an explanation for the sense of agency associated with thinking. Drawing on comparator models of action control, Vicente and Martínez-Manrique argue that the feeling of agency arises when predictions and incoming signals match. In the context of UT, the "prediction about the meaning" is triggered by an "intention to speak which is immediately aborted," leading to a feeling of authorship over the thought.
5. Comparison with Unworded Speech:
The sources also touch upon "unworded speech," described as the "experience of speaking in your own inner voice except that you have no experience of words at all" (Hurlburt and Heavey 2006, 211). While seemingly similar to UT, unworded speech retains a sense of "vocal characteristics" like rate and rhythm, which are absent in the atemporal experience of UT. Vicente and Martínez-Manrique suggest that both phenomena can be seen as points on a continuum of aborted inner speech, with UT representing an even earlier abortion where the temporal and phonetic aspects associated with the "emission" of speech are also lacking, leaving primarily the structured meaning.
6. Buddhist Perspective and Unsymbolized Experience:
The "Pasted Text" introduces the Buddhist perspective, which "emphasizes mindfulness and direct experience," aligning with the idea of transcending the limitations of thought and language for true understanding. The text posits that "thought arises first then language" and that "being truely present precludes consious symbolization of any sort."
Key Buddhist concepts highlighted:
Mind as a Mirror: The mind reflects reality, but thoughts and emotions can obscure this reflection.
Mindfulness: Practices aim to cultivate direct awareness of the present moment, beyond the constraints of thought and language.
Emptiness (Sunyata): All phenomena, including thoughts and concepts, lack inherent self-existence. Recognizing this emptiness leads to deeper understanding.
The concept of Nāma in early Buddhism is presented as "the pivot around which the entire early Buddhist conception of language revolves." In SN 1.61, Nāma is identified as "What oppresses everything? What has nothing greater than itself? What is the one thing that holds everything under its sway?" The answer to all these questions is Nāma, indicating that early Buddhism viewed language as a powerful and potentially oppressive force. This perspective resonates with the idea that true presence and understanding might lie beyond symbolic representation.
7. Implications for Cognitive Phenomenology:
Vicente and Martínez-Manrique discuss the implications of UT for the debate on cognitive phenomenology:
While UT suggests a general "what it is like" to think, it doesn't necessarily imply a distinct phenomenology for every specific thought content (thinking that p vs. thinking that q). The initial surprise of experiencing UT highlights the novelty of thinking without symbols, rather than the novelty of each specific unsymbolized thought.
The dependence of UT's semantic and syntactic features on language production mechanisms suggests that even unsymbolized thought is not necessarily "pure" or linguistically uncontaminated. The experience of UT is linked to the same underlying structures that give rise to the phenomenology of linguistic experience.
The feeling of agency in UT can be explained through its connection to aborted intentions to speak, supporting the idea that conscious thinking is an active process.
8. Conclusion:
The sources collectively present a compelling picture of unsymbolized thought as a genuine and significant aspect of inner experience. Research utilizing the DES method provides detailed phenomenological descriptions, while theoretical accounts propose that UT is best understood as an aborted form of inner speech, retaining its propositional structure and connection to language production mechanisms. The Buddhist perspective offers a broader philosophical context that values direct, unsymbolized experience as a path to deeper understanding. Further research is needed to fully elucidate the nature and implications of UT for our understanding of consciousness, thought, and the relationship between language and cognition.

Quiz Answer Key
Unsymbolized thought is described as the experience of having a specific, definite thought without being aware of it being conveyed in words, images, or any other symbols. Subjects reporting this phenomenon often initially struggle to characterize it, distinguishing it from inner speech due to the lack of symbolic features.
The Buddhist perspective aligns with the idea that true understanding and liberation arise from going beyond the limitations of thought and language. Practices like mindfulness aim to cultivate direct awareness of the present moment, reflecting a reality unfiltered by symbolic processing.
The Descriptive Experience Sampling (DES) method, developed by Hurlburt and collaborators, involves subjects carrying a beeper that randomly prompts them to record their inner experience at that precise moment. This method has revealed that unsymbolized thinking is a distinct and relatively common phenomenon, often unexpected by those who experience it.
Key characteristics of unsymbolized thought include being a distinct phenomenon, a way of experiencing (not just feeling), having explicit and differentiated content that is directly in experience, typically presenting all at once without sequentiality, and lacking the experience of words or other symbols.
The authors minimally characterize unsymbolized thought as a propositional phenomenon, meaning it has semantic and syntactic features analogous to the contents of utterances. They also argue that it is effable, meaning it can be rendered linguistically even though it doesn't appear in words initially.
The authors hypothesize that unsymbolized thinking is continuous with inner speech, suggesting it is a form of inner speech where the speech action is aborted before the intention to talk is fully implemented by motor commands. They argue this best explains the semantic and syntactic similarities and the sense of agency.
Unworded speech is described as the experience of speaking in one's inner voice without the experience of words, although there might be an awareness of vocal characteristics like rate and inflection, as well as the meaning. It differs from unsymbolized thought, which lacks the temporal and vocal characteristics associated with the sense of speaking.
The authors suggest that the sense of agency associated with unsymbolized thought can be explained by their model of it as aborted inner speech. The intention to speak and the involvement of the motor control system (efference copies, predictions) contribute to the feeling of authorship, even if the speech act is never fully realized.
The authors argue that the effability and familiarity of unsymbolized thought suggest that it draws on the syntax and semantics of one's own natural language. They contend that the conceptual structure of unsymbolized thought appears linguistically prepackaged, arranged according to the rules of the subject's language.
According to the authors, while unsymbolized thought shows that thinking has a generic phenomenology, it doesn't clearly demonstrate that each specific thought content has a distinct phenomenology. They also argue that its reliance on underlying linguistic mechanisms suggests that even unsymbolized thought is not necessarily "pure" or linguistically uncontaminated.

FAQ
1. What is unsymbolized thinking (UT) as described by researchers like Hurlburt? Unsymbolized thinking (UT) refers to the experience of having a distinct, definite thought without any awareness of that thought being conveyed through words, images, or other symbols. Individuals who report UT experience it as a thinking, not a feeling or other type of internal event, with a clear and specific content that is directly present in their experience. A key characteristic is that UT typically occurs "all at once" without a sense of unfolding or sequentiality, and crucially, without any accompanying experience of language or other symbolic representation.
2. How does the Buddhist perspective relate to the concept of unsymbolized thought? The Buddhist perspective, with its emphasis on mindfulness and direct experience, aligns with the idea that true understanding and liberation come from transcending the limitations of thought and language. Buddhist teachings often describe the mind as a mirror obscured by a constant stream of thoughts and emotions. Practices like meditation aim to cultivate direct awareness of the present moment, fostering a deeper understanding of reality that exists beyond conscious symbolization. The concept of "emptiness" (sunyata) further suggests that all phenomena, including thoughts and concepts, lack inherent self-existence, implying that true understanding involves recognizing this emptiness beyond linguistic and conceptual frameworks.
3. What is "nāma" in early Buddhist thought, and how does it relate to language and consciousness? In early Buddhist thought, "nāma" (name) is considered a pivotal concept in understanding language. It forms a fundamental cognitive dyad with "rūpa" (form) but also functions as an independent agent with its own characteristics. Notably, nāma holds a unique relationship with consciousness. A significant early Buddhist text (SN 1.61) portrays nāma as the universal oppressor, the one thing that holds everything under its sway, with nothing greater than itself. This highlights that early Buddhism did not view language as trivial but as a powerful force shaping our experience.
4. How do the researchers Vicente and Martínez-Manrique characterize unsymbolized thinking? Vicente and Martínez-Manrique analyze UT as a propositional phenomenon, meaning that even without symbols, UTs are experienced as compositional conceptual states with semantic and syntactic features analogous to the contents of utterances. They argue that UTs are effable, meaning they can be given a relatively straightforward linguistic rendition, even though they don't initially appear in words. Based on these characteristics, they propose that UT is continuous with the activity of inner speech, specifically as a form of inner speech where the speech act is aborted before the intention to speak is fully implemented by motor commands.
5. What evidence supports the existence of unsymbolized thinking, and what are some challenges to this idea? The primary method used to gather evidence for UT is Descriptive Experience Sampling (DES), where subjects are prompted at random times to describe their inner experiences. Reports from DES studies indicate that some individuals do experience thoughts without words or other symbols, and that this phenomenon is often unexpected even for those who experience it. Challenges to the existence of UT include methodological criticisms of DES and the suggestion that reports of UT might be confabulations, where individuals mistakenly believe they are thinking without symbols. However, proponents argue that the consistency of reports and the surprise of subjects experiencing UT for the first time argue against mere confabulation.
6. How do Vicente and Martínez-Manrique explain the origin and nature of unsymbolized thinking? Vicente and Martínez-Manrique propose that UT originates as an aborted act of inner speech. They suggest that the process of inner speech begins with a non-conscious intention to express a thought, which becomes increasingly specific, engaging semantic, syntactic, and phonological representations and eventually motor commands. They hypothesize that UT occurs when this process is aborted before reaching the phonological level. The result is a prediction about the meaning of the intended message, experienced directly as a thought content without accompanying symbolic or perceptual elements.
7. How does the theory of UT as aborted inner speech account for the sense of agency associated with thinking? The sense of agency, the feeling that we are the authors of our thoughts and actions, can be explained through the lens of the corollary discharge model. This model suggests that we feel agency when our predictions about the outcomes of our actions match the incoming sensory signals. Vicente and Martínez-Manrique extend this to the mental domain, arguing that in UT, the prediction about the meaning of a linguistic expression (stemming from an aborted intention to speak) is experienced. We feel authorship because this prediction is triggered by our intention, even if the full speech act is not realized. This contrasts with views that see conscious thoughts as simply occurring without intention or agency.
8. What are the implications of unsymbolized thinking for the debate on cognitive phenomenology? UT suggests that there is a proprietary phenomenology to thinking, distinct from perceiving or saying. However, it doesn't as clearly demonstrate that each specific thought content has a unique phenomenology that differentiates it from other thoughts. The surprise often reported by individuals experiencing UT for the first time indicates a novel kind of experience (thinking without symbols), rather than a novel feeling for each new unsymbolized thought content. Furthermore, the connection of UT to the mechanisms of language production suggests that its semantic-related phenomenological properties are linked to those of linguistic experience, implying that even "pure thought" as experienced in UT might be intertwined with linguistic categories.
