1. Introduction: From Event Horizons to Everyday Life
When we think about the boundary between what we can directly perceive and what we can only infer or imagine, the event horizon of a black hole presents an extreme example. The event horizon marks the point at which information from an object—whether a star, a planet, or even light—becomes inaccessible to an observer outside the black hole. In a literal sense, the event horizon is the boundary of perceptual meaning: beyond it, there is no more sensory data to process. Yet, through cognitive instantiation, we can still engage with the idea of what happens beyond that boundary, drawing on scientific theories and conceptual models.
This distinction between perceptual and cognitive instantiation extends far beyond black holes. It’s a critical concept that underpins how we understand not just the cosmos, but the very nature of meaning itself. In this blog post, we’ll explore how these two kinds of instantiation—one grounded in sensory experience and the other in cognitive reflection—play crucial roles in how we construct meaning across a broad spectrum of phenomena, from everyday experiences to scientific theory and beyond.
2. Everyday Experience: Seeing, Remembering, Imagining
Perceptual and cognitive instantiation are not just abstract concepts—they are at play in our everyday lives. Much of what we experience, whether it’s the feeling of the sun on our skin or the sound of a friend’s voice, is a process of meaning-making that relies on both sensory input and cognitive processes. However, experience is not inherently meaningful on its own. Meaning is instantiated through the activity of a meaner, using a semiotic system to actualise potential meaning into meaningful experience.
Perceptual instantiation is the process by which we actualise meaning through sensory input. When we see a tree, hear a bird singing, or feel warmth from the sun, these sensory stimuli are transduced into meanings that we understand, based on the semiotic resources we have at our disposal. Light, sound, and temperature are not mere physical occurrences; they become recognisable as “tree,” “bird,” and “comfort” through the cognitive systems we employ to interpret them.
But our experience goes beyond what we perceive in the present moment. Cognitive instantiation refers to the meaning we instantiate through reflection, memory, and imagination. We can think about a friend’s voice even when they aren’t speaking, or imagine a future holiday without being there. Such meanings are not grounded in sensory perception but are drawn from prior experiences, abstract representations, and the symbolic systems that enable us to construct meaning beyond the immediate sensory world.
These two processes—perceptual and cognitive—are constantly at work, often interwoven. The sight of a familiar face isn’t just the recognition of a pattern of features; it’s also the instantiation of all the past experiences, emotions, and associations we have with that face. Meaning is not inherent in the face itself; it is brought into being by the semiotic systems that allow us to construe it.
3. Symbolic Systems and Cultural Practices
One of the key aspects of cognitive instantiation is the role of symbolic systems and cultural practices in shaping how we instantiate meaning. While perceptual instantiation relies on individual sensory input, cognitive instantiation is deeply influenced by the cultural and symbolic resources available to a meaner. Language, art, mathematics, and other semiotic systems provide the frameworks through which cognitive processes can engage with and construct meaning.
Take, for example, how language shapes our perception of reality. The word “tree” does not just label a physical object; it draws on an entire cultural system of meaning that includes notions of nature, growth, and environment. Without the symbolic system of language, the meaning of a tree could not be instantiated in the same way. Similarly, in mathematics, we do not simply “see” numbers in the world, but rather, we instantiate meaning through abstract representations that allow us to engage with the material world in systematic, predictive ways.
This idea can also be seen in cultural practices. Stories, myths, rituals, and art are all ways in which cognitive instantiation is influenced by collective systems of meaning. These practices are not just individual acts of reflection—they are shared frameworks that enable groups of people to create, store, and convey meaning across time and space. The distinction between perceptual and cognitive instantiation becomes particularly important in understanding how we can meaningfully engage with the world when sensory input is limited, abstract, or mediated through cultural systems.
4. Meaning, Absence, and Imagination
An intriguing aspect of cognitive instantiation is its ability to create meaning in the absence of direct sensory input. We can think about things we have never seen, recall experiences we were not part of, or imagine possibilities that don’t yet exist. This is the power of imagination—the ability to instantiate meaning without needing direct referents in the material world.
When we imagine something, whether it’s a fictional world, a historical event, or a distant future, we are engaging in cognitive instantiation. The meanings we create are not derived from sensory data, but are constructed through our capacity to reflect, synthesise, and project meaning into hypothetical or speculative realms. For example, imagining life on another planet involves a complex process of drawing on scientific knowledge, cultural representations, and speculative thought, all of which allow us to instantiate meaning about something that is not immediately perceptible.
The distinction between perceptual and cognitive instantiation also has significant implications for how we understand absence. For instance, when someone we love is no longer present, we do not simply “lose” the meaning of that person. Instead, we continue to instantiate meaning through memory, imagination, and reflection, keeping the individual alive in our cognitive experience. This process, far from being passive, is an active construction of meaning that shapes how we relate to the absence of sensory input.
5. Science, Theory, and the Limits of Observation
The role of cognitive instantiation becomes especially important in the realm of science, where theory and observation must often work together to make sense of phenomena that are not directly accessible through sensory perception. In the case of black holes, as mentioned earlier, the event horizon marks a boundary beyond which direct observation is impossible. Yet, through cognitive instantiation, scientists are still able to model, infer, and make predictions about the behaviour of objects near the event horizon.
This is true not just for black holes, but for all phenomena that fall outside the reach of direct sensory observation. Consider the subatomic world, where particles and forces are inferred through complex theories and experimental data rather than direct sensory experience. In these cases, cognitive instantiation allows us to engage with meaning through abstract theories, even when the data available for perceptual processing is limited or non-existent.
The interplay between data (perceptual input) and theory (cognitive models) highlights the ways in which meaning is instantiated through both sensory and cognitive processes. Science is not just a passive reflection of the world; it is an active construction of meaning based on the cognitive capacity to abstract, hypothesise, and model the material world. Theories like relativity or quantum mechanics allow us to instantiating meaning about the universe, not from immediate perception, but through complex and rigorous cognitive processes.
6. Ontology and the Construction of Meaning
The question arises: if meaning is always instantiated by meaners through semiotic systems, what does this say about the nature of reality itself? This is where the tension between ontology (the nature of being) and epistemology (the study of knowledge) becomes crucial. If meaning only comes into being through the act of instantiation, then reality, as we experience it, is not something independent of us, but something that we continuously construe and construct through our semiotic systems.
This view challenges traditional notions of objective reality as a pre-existing, independent entity. Instead, it suggests that what we call “reality” is always already a semiotic construct—an ongoing process of meaning-making that is deeply entangled with the meaner’s capacities and the symbolic systems available to them. In this view, ontology is inseparable from semiotics: what is “real” is what can be construed and instantiated through semiotic systems. Reality is not something that exists independently of our perception and cognition; it is always mediated by the symbolic systems we use to make sense of it.
7. Conclusion: A Layered View of Reality
In conclusion, the distinction between perceptual and cognitive instantiation reveals that our engagement with the world is never a simple act of discovery; rather, it is a complex process of construal. Meaning is not inherent in the world waiting to be uncovered—it is continuously actualised through both sensory perception and cognitive reflection. Whether we are experiencing the immediacy of a tree in the park, imagining a future event, or modelling the motion of distant stars, meaning is always instantiated through our semiotic systems.
This layered construal of reality, where meaning is always mediated by semiotic systems, offers a richer and more dynamic view of how we relate to the world. Rather than being passive observers, we are active constructors of meaning, constantly engaging with and shaping the world through the instantiation of meaning—whether perceptual or cognitive. This approach to reality invites us to reconsider the nature of experience itself, and to see meaning not as something waiting to be discovered, but as something we continuously bring into being through our engagement with the world.
