What Carries Our Personal Identity? | Arnold Zuboff
Closer To TruthKey Moments
Personal identity is an illusion: all conscious beings share a single subjective experience, but we are tricked into believing we are distinct individuals due to limited information.
Key Insights
The immediacy of first-person experience is the sole criterion for personal identity, not objective descriptions like the body or mind.
The probability of any individual existing, given the countless near-identical possibilities at conception (1 in 8 septillion), is astronomically low under the standard view, making universalism—where existence is inevitable—a far more probable explanation.
The problem of induction can be solved using probability, arguing that we rationally believe the next bird will be blue because it makes the observed pattern of blue birds most probable, rather than being a mere habit.
Universalism is not a mystical concept but is grounded in empirical discovery, philosophical arguments, and probabilistic reasoning, akin to solving the problem of induction.
The 'Sleeping Beauty problem' supports universalism by suggesting that each awakening experience, regardless of when it occurs or how many there are, is fundamentally the same subjective experience due to its immediacy.
The 'type' vs. 'token' distinction is crucial: universalism posits that our subjective experience is a 'type' (like Moby Dick) that exists in many 'tokens' (like copies of the novel), rather than each instance being a distinct 'token' of a unique self.
The immediacy of first-person experience as the sole criterion for selfhood
Arnold Zuboff's theory of universalism begins by re-framing personal identity around the immediate, first-person nature of conscious experience. He argues that what makes an experience 'mine' is its subjective immediacy—the direct, unmediated awareness of it. Any objective characteristics of the entity experiencing it are secondary. This is illustrated through a joke about a barber, an academic, and a bald man, where the academic mistakenly identifies himself by the objective characteristic of hairlessness rather than the subjective experience of being woken up. Zuboff posits that the usual view of personal identity prioritizes objective descriptions (e.g., the same body, memory) as foundational, with experience being a mere consequence. However, universalism reverses this: the subjective immediacy of experience is what makes something 'me.' The objective characteristics are then an 'afterthought' that happens to be having this immediate experience, deriving their identity from it. This perspective suggests that the boundaries we perceive between ourselves and others are illusions, as the essential quality of experience—its immediacy—is universal across all conscious beings.
The astronomical improbability of individual existence under the standard view
Zuboff highlights the immense probabilistic argument against the conventional understanding of personal identity. He notes that on the usual view, the conception of any single individual is an event of infinitesimal probability. For instance, if one of roughly 200 million sperm cells had reached an egg differently, a sibling would have existed instead, and 'you' would never have been. This improbability compounds exponentially when considering the conception of parents, grandparents, and so forth, all throughout natural history. The cumulative probability of a specific individual existing can be as low as one in eight septillion. Zuboff likens this to a cruel tyrant's game involving a single colored grain of sand lost in the desert, deeming the odds of winning infinitesimally small and thus the premise of the game inherently rigged. This extreme improbability, he argues, makes the standard view of personal identity untenable as a coherent explanation for our existence. The alternative, universalism, suggests that existence is not a matter of improbable chance but is, in some sense, inevitable.
Universalism as the resolution to the problem of induction
Part two of Zuboff's argument addresses how his view is grounded in empirical discovery and probability, not mysticism. He tackles the problem of induction, exemplified by observing a hundred blue birds on a newly discovered island and inferring that the next bird will also be blue. David Hume famously argued this is irrational, as the next bird's color is logically distinct from the observed ones. Zuboff disagrees, asserting that our belief is rational because it relies on probability. The observed pattern of a hundred blue birds is made most probable if the general population of birds is blue. Rejecting this hypothesis implicitly assumes that an improbable event (a hundred blue birds from a non-blue population) has occurred. Therefore, believing the next bird will be blue is a rational inference to the hypothesis that best explains the evidence. Zuboff extends this probabilistic reasoning to address skepticism, arguing that the pattern of our experiences is more probable under the hypothesis of an external world than under radical skeptical scenarios, unless those scenarios involve complex, ad hoc specifications that themselves become improbable.
Experience as a 'type' rather than a 'token'
Zuboff introduces the distinction between 'types' and 'tokens' to further elaborate on universalism. He uses the analogy of a novel like 'Moby Dick.' The novel itself is the 'type,' and each physical copy is a 'token' of that type. While each copy is distinct, they all embody the same story and characters. Similarly, Zuboff argues, our conscious experience is a 'type' characterized by immediacy. Each instance of conscious experience is a 'token' of this universal type. The apparent individuality of our experiences arises from the limited information available to each 'token' (or individual organism), creating the illusion that 'this much is me.' However, the underlying experiential nature, the 'type,' is shared. He proposes that a being's identity is not tied to a specific physical instantiation (like a particular brain or body) but to this broader type of experience, which is fundamentally immediacy. This concept is explored further through thought experiments involving brain bisection and duplication, where the subjective experience as a 'type' remains constant, irrespective of the number of 'tokens' or their specific configurations.
The 'Sleeping Beauty' puzzle as support for universalism
The 'Sleeping Beauty problem,' a philosophical thought experiment, is presented as further evidence for universalism. In the puzzle variant Zuboff discusses, a sleeper is awakened either once or a trillion times over a trillion days. Each time they awaken, they are hypnotized to forget the previous awakenings. The core question is whether, upon awakening, the sleeper should infer that only one awakening has occurred or that a trillion have. Zuboff argues that it's a mistake to consider each awakening a distinct experience. Because what defines an experience is its immediacy, and all awakenings possess this quality equally, they are all fundamentally 'this awakening.' This leads to the conclusion that the specific objective time or conditions of the awakening are irrelevant to its subjective reality. If immediacy is all that matters, then the probability of having 'this experience' is not dependent on whether it's one awakening or a trillion. This invariance of subjective experience across multiple potential instances strongly supports the idea that what matters is the universal quality of immediacy, not the particular circumstances or physical token experiencing it, thus aligning with universalism.
Universalism and the nature of consciousness
Zuboff emphasizes that universalism does not require a specific theory about the nature of consciousness itself. Whether consciousness is material, immaterial, or something else entirely is not central to his argument. The crucial element is the *presence* of conscious experience, and specifically, its quality of immediacy. He accepts that not all perceived states might qualify as consciousness if they lack this direct, first-person quality. However, for any state that *is* considered consciousness, if it possesses immediacy, then it is part of the universal subject of experience. This makes the theory neutral with respect to ongoing debates about the mind-body problem or the origins of consciousness, focusing instead on how we know ourselves through subjective awareness.
Unification as a precursor and broader consideration
The concept of 'unification,' which Zuboff developed at age 15, serves as a foundational idea for universalism. Unification proposes that if there were an exact duplicate of oneself with an identical pattern of experience, one's identity would also exist in that duplicate. This idea, initially about precise experiential duplicates, later broadened. It moves from the 'token' view—where each instantiation is unique—to a 'type' view, suggesting that the experience itself is the fundamental entity. This is akin to saying that the character of Ishmael in 'Moby Dick' is the same 'type' across all its 'tokens' (copies). Zuboff also touches upon how universalism applies to other philosophical positions, such as dualism and monism (the view that only one thing exists), arguing that universalism provides the most probabilistically sound framework for understanding identity regardless of the underlying ontology of reality.
The implications of universalism for our understanding of self and others
The radical conclusion of universalism is that the perceived boundaries between individuals are illusory. If one subject of experience underlies all conscious beings, then 'everyone is that same me.' The apparent distinctions arise from the limited information available within each particular instance of experience, creating the illusion of separation. However, this also implies that each conscious being is, in a profound sense, experiencing limited aspects of a single, overarching subjective reality. The implications extend to empathy, ethics, and our fundamental understanding of existence, suggesting a radical interconnectedness that transcends individualistic perspectives. The feeling of being distinct is explained as a consequence of how consciousness is mediated, but at the foundational level, all conscious beings are expressions of the same underlying subject of experience, making the boundaries of 'me' and 'you' a product of perspective rather than fundamental reality.
