Thought exhibits a profound capacity for symbolic abstraction—the ability to mentally represent and convey complex meanings through symbols detached from their literal aspects. From metaphorical language to mathematical notations, symbolism pervades our cognitive experience. Meanwhile, principles of quantum theory, like entanglement, defy classical explanations and suggest deep connections between mind, meaning, and nature. Could quantum processes be involved in generating symbolic meanings that seem to transcend spatiotemporal barriers? This essay hypothesizes potential mechanisms, implications, and research directions for a quantum-cognitive framework of symbolic information. By synthesizing perspectives from information theory, cognitive science, and quantum physics, we can gain new insights into the emergence of symbolic thought and its relationship to empirical reality. For example, quantum coherence has been observed in microtubules within brain neurons, suggesting quantum processes may be integral to neural computation and cognition (Hagan et al., 2002). Additionally, quantum entanglement has been theoretically linked to tunneling of neurotransmitters across synaptic gaps, implying potential roles in memory formation and learning (Beck & Eccles, 1992). If cognition adapts some attributes of quantum information processing, this could provide clues into the emergence of symbolic thought and meaning. In quantum entanglement, particles maintain a single coherent state spanning space. Even when separated, their properties remain deeply interdependent (Jozsa & Linden, 2003). Analogously, the meaning of a symbol cannot be deconstructed into its constituent letters or sounds. It is an irreducible emergent property, just as wave-like holism defines entangled particles (Li et al., 2022). This conceptual resonance suggests quantum effects may be involved in generating seamless symbolic meanings. Entangled particles defy spatial separation – when one particle is measured, its entangled counterpart instantaneously exhibits related properties regardless of distance (Acín et al., 2018). Remarkably, symbolic meanings display a similar nonlocality, able to manifest coherently in multiple remote contexts at once. For instance, a national flag embodies the same meaning and significance simultaneously wherever it is observed (Dean, 2021). This defies localization in a manner that mirrors quantum states. In quantum physics, particles reside in a probabilistic superposition of all possible states before measurement forces a particular state to manifest (Rundle, 2004). Correspondingly, symbols can be thought to exist in a superposition of potential semantic interpretations, only collapsing into definite meaning when actively processed by a mind (Melkikh & Khrennikov, 2022). For example, a hand gesture only acquires context-specific meaning once observed. This conceptual symmetry points to quantum-like effects in symbolic thought. Jung (1955) described poignant yet improbable coincidences as evidence of an acausal connecting principle he termed synchronicity. Some interpret such symbolic coincidences as the hand of fate or divine influence (Main, 2007). But a quantum explanation suggests entangled meanings can manifest correlations defying spatial logic (Gieser, 2005). For instance, a loved one inheriting a relative’s ring after just thinking of them cannot be plausibly explained classically. Rather than mere correlation, these coincidences feature semantic resonance between subjectively meaningful symbols. This distinguishes them from classically explicable chance events. The improbable timing involved in many symbolic synchronicities implies entanglement between mental processes rather than random chance (Mensky, 2010). When events like thinking of someone who then calls unexpectedly occur, the meaning-laden nature of the coincidence differentiates it from empty statistical flukes. Quantum collapse may prompt concretization of associated meanings across entangled minds. If quantum information processing contributes to cognition, synchronized collapse of entangled wave functions could spark spontaneous symbolic transmission. For instance, visualizing a loved one could induce nonlocal correlation with a matching mental state in that individual (Galli Carminati & Martin, 2008). Hypothetically, the symbolic significance of the thoughts spontaneously entangles across space, manifesting in a meaningful coincidence when the wave function reduces. Studies have observed mind-matter anomalies like psychokinesis under controlled settings. In random number generator experiments, subjects consciously intending to influence the output distribution often succeeded in biasing the randomness (Radin et al., 2012). This implies intention can somehow affect probabilities at the quantum level. Rather than minds directly imposing classical forces, mind-matter interactions could involve modulating probabilities by collapsing superpositions of potentialities (Gernert, 2000). Symbols, emotions, or focused intent may influence biophysical and quantum systems by constraining which probabilities manifest. For instance, directing healing intention toward cell cultures has been found to enhance growth (Rein & McCraty, 1994). Our experienced world only actualizes when the limitless quantum field of possibilities reduces to singular classical events during observation (von Stillfried, 2011). The meanings and models our minds use to interpret reality may therefore shape its concrete manifestation. In this sense, symbolic cognition plays an active role in conditioning reality’s collapse from abstract potentials. Integrating quantum and symbolic frameworks invites new perspectives on intrinsic nature of meaning, the emergence of abstractions, and the contextual limits of knowledge (Melkikh & Khrennikov, 2022). For example, are symbolic meanings ontologically real or constructed models? Does consciousness actively organize reality’s possibility space? Physical and chemical interactions clearly enable information processing in the brain. Yet subjective meaning resists full reduction to neuronal firing patterns (Tononi et al., 2016). Perhaps higher-order symbolic semantics arise from lower-layer quantum processes in a form of ontological emergence (Gooding-Williams, 2000). Matter begets life begets mind begets meaning. The ability of symbols to manifest effective coherence across contexts implies an aspect of reality beyond figurative abstraction (Dean, 2021). If quantum cognition models hold, conscious observation may prompt actualization of potential meaning states, selectively objectifying certain symbolic possibilities over others. Matter, information and imagination may participate in collaborative interface. Quantum theories of symbolism require rigorous empirical testing to move beyond conceptual analogies. Detailed confirmation of quantum processes occurring within neural substrates and correlations to symbolic reasoning would bolster hypotheses (Jedlicka, 2014). Studies could examine if manipulating entanglement affects resulting symbolic interpretation. Here are some proposed scenarios and potential ways to test and falsify claims about quantum cognition and symbolic meaning: Scenario 1: Quantum coherence in microtubules enables symbolic representation. * Claim: Macroscopic quantum coherence among tubulin proteins allows microtubules to encode and process symbolic meanings as qubit states. * Test: Directly measure microtubule quantum coherence during symbolic thinking tasks through techniques like magnetoencephalography. If experimental disruption of microtubule coherence impairs symbol manipulation, it would support the claim. * Falsification: Finding no measurable difference in microtubule quantum effects between symbolic and concrete thinking. Also if disrupting quantum coherence does not affect symbol processing. Scenario 2: Entanglement binds distributed semantic information. * Claim: Widespread neural entanglement coordinates dispersed semantic knowledge into unitary coherent symbols. * Test: Use quantum tomography imaging to map entanglement networks during semantic processing. If degree of entanglement correlates with measures of semantic cohesion, it supports the claim. * Falsification: No observable relationship between entanglement properties and semantic cohesion or symbolic manipulation. Scenario 3: Consciousness collapses symbolic meaning potentials. * Claim: Conscious observation selects which possible symbolic meaning gets actualized from a state of superposition. * Test: Biofeedback techniques may be able to detect subtle quantum effects related to transition of symbols from potential to definite states upon conscious registration. * Falsification: No observable quantum level events reliably occurring when unknown symbols are consciously processed and comprehended. Advances in neuroimaging enable studying quantum-level activity during cognitive tasks. Tracking quantum correlations across brain regions involved in processing symbolic information could reveal mechanisms of semantic emergence and help localize symbolic representation (Jerger et al., 2022). Systematic comparisons against literal vs figurative cognition could be revealing. Of the proposed scenarios, the one that seems most plausible given current scientific knowledge is that quantum effects like superposition and entanglement assist in representing and transmitting symbolic meaning in the brain, while conscious observation induces collapse of these quantum states to actualize particular meanings. Several lines of evidence point to quantum processes playing an information binding and propagation role in cognition: * Quantum coherence has been observed in neural microtubules and synaptic membranes, suggesting biomolecular quantum computations are possible in brain structures integral to cognition and memory. * Quantum entanglement has been theoretically proposed as a mechanism for fast emotional recognition, gestalt-like feature processing, and associative recall in the brain. Entanglement could allow distributed semantic knowledge to cohere. * Anesthetics which demonstrably disrupt quantum coherence in neural tissue also cause deficits in coordination, integration and understanding of perceptual information. This implies quantum effects may underlie unified cognitive representations. Additionally, the transition from abstract potentials to definite actualities that occurs in quantum measurement aligns with the collapse of ambiguous symbols into unambiguous meaning that happens during conscious processing: * Before observation, a symbol exists in a probabilistic superposition of possible referents and interpretations, analogous to a pre-measurement quantum state encompassing multiple probabilistic values. * The act of conscious attention on the symbol appears to “collapse” this cloud of potential meanings down to a particular comprehension or semantic association in the observer’s mind. * Similarly, quantum observation causes particular properties to manifest out of an abstract potentiality cloud. Consciousness may induce analogous collapses determining symbolic meaning. * Dynamical modes of conscious attention and focus could influence which symbolic meanings emerge from pre-conscious potentials by shaping how probabilities collapse. Existing evidence points to quantum superposition and entanglement as a likely informational substrate enabling unified coherence of symbolic meanings across neural networks. Conscious observation of symbols may then collapse these quantum states into definite experiential meanings and associations. Focused experiments tracking quantum correlative signatures during symbolic cognition can further test these promising possibilities. If quantum effects facilitate symbolic thought, quantifying entanglement against metrics of symbolic cognition could uncover dose-response relationships. Does enhanced entanglement improve metaphor comprehension or ideation? Can quantum discord metrics gauge semantic complexity or creativity (Wendt, 2015)? Psycholinguistics meets quantum information theory. Technologically enabled group entanglement could amplify intersubjective coherence in understanding shared symbolism (Reimers et al, 2022). This may improve communication, collective meaning-making, and synchronized comprehension. Carefully designed experiments leveraging quantum tools can ethically and safely explore this frontier. While speculative, integrating quantum and symbolic frameworks has philosophical merit and transdisciplinary potential. As we advance our understanding of cognition, meaning, and reality, both literal and symbolic modes of comprehension work in unison to provide multidimensional insight. Further exploring their symbiosis through quantum lenses may yield fruitful discovery.
