Today, some might think that atomism and Aristotle’s teleological view have evolved into a theory of cells that resolves the acorn-oak tree identity problem. The purpose, or ergon, of both the acorn and the oak tree are present in the zygote, the cell that forms when male and female sex cells combine. This zygote cell contains the genetic material, or the instructions, for how the organism will develop to carry out its intended purpose.
But not all identity problems are so easily solved today. What if the author of this chapter lived in a house as a child, and years later, after traveling in the highly glamorous life that comes with being a philosopher, returned to find the house had burned down and been rebuilt exactly as it had been. Is it the same home? The generic questions that center on how we should understand the tension between identity and persistence include:
- Can a thing change without losing its identity?
- If so, how much change can occur without a loss of identity for the thing itself?
This section begins to broach these questions of identity and self.
The Ship of Theseus
Consider the following thought experiment. Imagine a wooden ship owned by the hero Theseus. Within months of launching, the need to replace decking would be evident. The salt content of sea water is highly corrosive. Accidents can also happen. Within a common version of the thought experiment, the span of one thousand years is supposed. Throughout the span, it is supposed that the entire decking and wooden content of the ship will have been replaced. The name of the ship remains constant. But given the complete change of materials over the assumed time span, in what sense can we assert that the ship is the same ship? We are tempted to conceptualize identity in terms of persistence, but the Ship of Theseus challenges the commonly held intuition regarding how to make sense of identity.
Similarly, as our bodies develop from zygote to adult, cells die and are replaced using new building materials we obtain though food, water, and our environment. Given this, are we the same being as we were 10 or 20 years ago? How can we identify what defines ourselves? What is our essence? This section examines answers proposed by secular and religious systems of belief.
Write Like a Philosopher
Watch the video “Metaphysics: Ship of Theseus” in the series Wi-Phi Philosophy. You will find five possible solutions for making sense of the thought experiment. Pick one solution and explain why the chosen solution is the most salient. Can you explain how the strengths outweigh the stated objections—without ignoring the objections?
Judeo-Christian Views of Self
The common view concerning identity in Judeo-Christian as well as other spiritual traditions is that the self is a soul. In Western thought, the origin of this view can be traced to Plato and his theory of forms. This soul as the real self solves the ship of Theseus dilemma, as the soul continuously exists from zygote or infant and is not replaced by basic building materials. The soul provides permanence and even persists into the afterlife.
Much of the Christian perspective on soul and identity rested on Aristotle’s theory of being, as a result of the work of St. Thomas Aquinas. Aquinas, a medieval philosopher, followed the Aristotelian composite of form and matter but modified the concept to fit within a Christianized cosmology. Drawing upon portions of Aristotle’s works reintroduced to the West as a result of the Crusades, Aquinas offered an alternative philosophical model to the largely Platonic Christian view that was dominant in his day. From an intellectual historical perspective, the reintroduction of the Aristotelian perspective into Western thought owes much to the thought of Aquinas.
In Being and Essence, Aquinas noted that there was a type of existence that was necessary and uncaused and a type of being that was contingent and was therefore dependent upon the former to be brought into existence. While the concept of a first cause or unmoved mover was present within Aristotle’s works, Aquinas identified the Christian idea of God as the “unmoved mover.” God, as necessary being, was understood as the cause of contingent being. God, as the unmoved mover, as the essence from which other contingent beings derived existence, also determined the nature and purpose driving all contingent beings. In addition, God was conceived of as a being beyond change, as perfection realized. Using Aristotelian terms, we could say that God as Being lacked potentiality and was best thought of as that being that attained complete actuality or perfection—in other words, necessary being.
God, as the ultimate Good and Truth, will typically be understood as assigning purpose to the self. The cosmology involved is typically teleological—in other words, there is a design and order and ultimately an end to the story (the eschaton). Members of this tradition will assert that the Divine is personal and caring and that God has entered the narrative of our history to realize God’s purpose through humanity. With some doctrinal exception, if the self lives the good life (a life according to God’s will), then the possibility of sharing eternity with the Divine is promised.
Think Like a Philosopher
Watch this discussion with Timothy Pawl on the question of eternal life, part of the PBS series Closer to the Truth, “Imagining Eternal Life”.
Is eternal life an appealing prospect? If change is not possible within heaven, then heaven (the final resting place for immortal souls) should be outside of time. What exactly would existence within an eternal now be like? In the video, Pawl claimed that time has to be present within eternity. He argued that there must be movement from potentiality to actuality. How can that happen in an eternity?
Hindu and Buddhist Views of Self
Within Hindu traditions, atman is the term associated with the self. The term, with its roots in ancient Sanskrit, is typically translated as the eternal self, spirit, essence, soul, and breath (Rudy, 2019). Western faith traditions speak of an individual soul and its movement toward the Divine. That is, a strong principle of individuation is applied to the soul. A soul is born, and from that time forward, the soul is eternal. Hinduism, on the other hand, frames atman as eternal; atman has always been. Although atman is eternal, atman is reincarnated. The spiritual goal is to “know atman” such that liberation from reincarnation (moksha) occurs.
Brahman
Hindu traditions vary in the meaning of brahman. Some will speak of a force supporting all things, while other traditions might invoke specific deities as manifestations of brahman. Escaping the cycle of reincarnation requires the individual to realize that atman is brahman and to live well or in accordance with dharma, observing the code of conduct as prescribed by scripture, and karma, actions and deeds. Union of the atman with brahman can be reach though yoga, meditation, rituals, and other practices.
Buddha rejected the concept of brahman and proposed an alternate view of the world and the path to liberation. The next sections consider the interaction between the concepts of Atman (the self) and Brahman (reality).
The Doctrine of Dependent Origination
Buddhist philosophy rejects the concept of an eternal soul. The doctrine of dependent origination, a central tenet within Buddhism, is built on the claim that there is a causal link between events in the past, the present, and the future. What we did in the past is part of what happened previously and is part of what will be.
The doctrine of dependent origination (also known as interdependent arising) is the starting point for Buddhist cosmology. The doctrine here asserts that not only are all people joined, but all phenomena are joined with all other phenomena. All things are caused by all other things, and in turn, all things are dependent upon other things. Being is a nexus of interdependencies. There is no first cause or prime mover in this system. There is no self—at least in the Western sense of self—in this system (O’Brien 2019a).
The Buddhist Doctrine of No Self (Anatman)
One of many distinct features of Buddhism is the notion of anatman as the denial of the self. What is being denied here is the sense of self expressed through metaphysical terms such as substance or universal being. Western traditions want to assert an autonomous being who is strongly individuated from other beings. Within Buddhism, the “me” is ephemeral.

Suffering and Liberation
Within Buddhism, there are four noble truths that are used to guide the self toward liberation. An often-quoted sentiment from Buddhism is the first of the four noble truths. The first noble truth states that “life is suffering” (dukkha).
But there are different types of suffering that need to be addressed in order to understand more fully how suffering is being used here. The first meaning (dukkha-dukkha) is commensurate with the ordinary use of suffering as pain. This sort of suffering can be experienced physically and/or emotionally. A metaphysical sense of dukkha is viparinama-dukkha. Suffering in this sense relates to the impermanence of all objects. It is our tendency to impose permanence upon that which by nature is not, or our craving for ontological persistence, that best captures this sense of dukkha. Finally, there is samkhara-dukkha, or suffering brought about through the interdependency of all things.
Building on an understanding of “suffering” informed only by the first sense, some characterize Buddhism as “life is suffering; suffering is caused by greed; suffering ends when we stop being greedy; the way to do that is to follow something called the Eightfold Path” (O’Brien 2019b). A more accurate understanding of dukkha within this context must include all three senses of suffering.
The second of the noble truths is that the cause of suffering is our thirst or craving (tanha) for things that lack the ability to satisfy our craving. We attach our self to material things, concepts, ideas, and so on. This attachment, although born of a desire to fulfill our internal cravings, only heightens the craving. The problem is that attachment separates the self from the other. Through our attachments, we lose sight of the impermanence not only of the self but of all things.
The third noble truth teaches that the way to awakening (nirvana) is through a letting go of the cravings. Letting go of the cravings entails the cessation of suffering (dukkha).
The fourth truth is founded in the realization that living a good life requires doing, not just thinking. By living in accordance with the Eightfold Path, a person may live such that “every action of body, mind, and speech” are geared toward the promotion of dharma.

The Five Aggregates
How might the self (atman) experience the world and follow a path toward liberation? Buddhist philosophy posits five aggregates (skandhas), which are the thoughtful and iterative processes, through which the self interacts with the world.
- Form (rupa): the aggregate of matter, or the body.
- Sensation (vedana): emotional and physical feelings.
- Perception (samjna): thinking, the processing of sense data; “knowledge that puts together.”
- Mental formation (samskara): how thoughts are processed into habits, predispositions, moods, volitions, biases, interests, etc. The fourth skandhas is related to karma, as much of our actions flow from these elements.
- Consciousness (vijnana): awareness and sensitivity concerning a thing that does not include conceptualization.
Although the self uses the aggregates, the self is not thought of as a static and enduring substance underlying the processes. These aggregates are collections that are very much subject to change in an interdependent world.
Secular Notions of Self
In theology, continuity of the self is achieved through the soul. Secular scholars reject this idea, defining self in different ways, some of which are explored in the next sections.
Bundle Theory
One of the first and most influential scholars in the Western tradition to propose a secular concept of self was Scottish philosopher David Hume (1711–1776). Hume formed his thoughts in response to empiricist thinkers’ views on substance and knowledge. British philosopher John Locke (1632–1704) offered a definition of substance in his Essay Concerning Human Understanding. In Book XXIII, Locke described substance as “a something, I know not what.” He asserted that although we cannot know exactly what substance is, we can reason from experience that there must be a substance “standing under or upholding” the qualities that exist within a thing itself. The meaning of substance is taken from the Latin substantia, or “that which supports.”
If we return to the acorn and oak example, the reality of what it means to be an oak is rooted in the ultimate reality of what it means to be an oak tree. The ultimate reality, like the oak’s root system, stands beneath every particular instance of an oak tree. While not every tree is exactly the same, all oak trees do share a something, a shared whatness, that makes an oak an oak. Philosophers call this whatness that is shared among oaks a substance.
Arguments against a static and enduring substance ensued. David Hume’s answer to the related question of “What is the self?” illustrates how a singular thing may not require an equally singular substance. According to Hume, the self was not a Platonic form or an Aristotelian composite of matter and form. Hume articulated the self as a changing bundle of perceptions. In his Treatise of Human Nature (Book 1, Part IV), Hume described the self as “a bundle or collection of different perceptions, which succeed each other with inconceivable rapidity, and are in a perpetual flux and movement.”
Hume noted that what has been mistaken for a static and enduring self was nothing more than a constantly changing set of impressions that were tied together through their resemblance to one another, the order or predictable pattern (succession) of the impressions, and the appearance of causation lent through the resemblance and succession. The continuity we experience was not due to an enduring self but due to the mind’s ability to act as a sort of theater: “The mind is a kind of theatre, where several perceptions successively make their appearance; pass, re-pass, glide away, and mingle in an infinite variety of postures and situations” (Hume 1739, 252).
Which theories of self—and substance—should we accept? The Greek theories of substance and the theological theories of a soul offer advantages. Substance allows us to explain what we observe. For example, an apple, through its substance, allows us to make sense of the qualities of color, taste, the nearness of the object, etc. Without a substance, it could be objected that the qualities are merely unintelligible and unrelated qualities without a reference frame. But bundle theory allows us to make sense of a thing without presupposing a mythical form, or “something I know not what!” Yet, without the mythical form of a soul, how do we explain our own identities?
Anthropological Views
Anthropological views of the self question the cultural and social constructs upon which views of the self are erected. For example, within Western thought, it is supposed that the self is distinct from the “other.” In fact, throughout this section, we have assumed the need for a separate and distinct self and have used a principle of continuity based on the assumption that a self must persist over time. Yet, non-Western cultures blur or negate this distinction. The African notion of ubuntu, for example, posits a humanity that cannot be divided. The Nguni proverb that best describes this concept is “umuntu ngumuntu ngabantu” sometimes translated as “a person is a person through other persons” (Gade 2011). The word ubuntu is from the Zulu language, but cultures from southern Africa to Tanzania, Kenya, and Democratic Republic of the Congo all have words for this concept. Anthropological approaches attempt to make clear how the self and the culture share in making meaning.
The Mind as Self
Many philosophers, Western and non-Western, have equated the self to the mind. But what is the mind? A monist response is the mind is the brain. Yet, if the mind is the brain, a purely biological entity, then how do we explain consciousness? Moreover, if we take the position that the mind is immaterial but the body is material, we are left with the question of how two very different types of things can causally affect the other. The question of “How do the two nonidentical and dissimilar entities experience a causal relationship?” is known as the mind-body problem. This section explores some alternative philosophical responses to these questions.
Physicalism
Reducing the mind to the brain seems intuitive given advances in neuroscience and other related sciences that deepen our understanding of cognition. As a doctrine, physicalism is committed to the assumption that everything is physical. Exactly how to define the physical is a matter of contention. Driving this view is the assertion that nothing that is nonphysical has physical effects.
Think Like a Philosopher
Listen to the podcast “David Papineau on Physicalism” in the series Philosophy Bites.
Focus on the thought experiment concerning what Mary knows. Here is a summary of the thought experiment:
Mary is a scientist and specializes in the neurophysiology of color. Strangely, her world has black, white, and shades of gray but lacks color (weird, but go with it!). Due to her expertise, she knows every physical fact concerning colors. What if Mary found herself in a room in which color as we experience it is present? Would she learn anything? A physicalist must respond “no”! Do you agree? How would you respond?
John Locke and Identity
In place of the biological, Locke defined identity as the continuity lent through what we refer to as consciousness. His approach is often referred to as the psychological continuity approach, as our memories and our ability to reflect upon our memories constitute identity for Locke. In his Essay on Human Understanding, Locke (as cited by Gordon-Roth 2019) observed, “We must consider what Person stands for . . . which, I think, is a thinking intelligent Being, that has reason and reflection, and can consider it self as itself, the same thinking thing in different times and places.” He offered a thought experiment to illustrate his point. Imagine a prince and cobbler whose memories (we might say consciousness) were swapped. The notion is far-fetched, but if this were to happen, we would assert that the prince was now the cobbler and the cobbler was now the prince. Therefore, what individuates us cannot be the body (or the biological).

The Problem of Consciousness
Christof Koch (2018) has said that “consciousness is everything you experience.” Koch offered examples, such as “a tune stuck in your head,” the “throbbing pain from a toothache,” and “a parent’s love for a child” to illustrate the experience of consciousness. Our first-person experiences are what we think of intuitively when we try to describe what consciousness is. If we were to focus on the throbbing pain of a toothache as listed above, we can see that there is the experiencing of the toothache. Curiously, there is also the experiencing of the experiencing of the toothache. Introspection and theorizing built upon first-person inspections affords vivid and moving accounts of the things experienced, referred to as qualia.
An optimal accounting of consciousness, however, should not only explain what consciousness is but should also offer an explanation concerning how consciousness came to be and why consciousness is present. What difference or differences does consciousness introduce?

Rene Descartes and Dualism
Dualism, as the name suggests, attempts to account for the mind through the introduction of two entities. The dualist split was addressed earlier in the discussion of substance. Plato argued for the reality of immaterial forms but admitted another type of thing—the material. Aristotle disagreed with his teacher Plato and insisted on the location of the immaterial within the material realm. How might the mind and consciousness be explained through dualism?
Video
Mind Body Dualism
A substance dualist, in reference to the mind problem, asserts that there are two fundamental and irreducible realities that are needed to fully explain the self. The mind is nonidentical to the body, and the body is nonidentical to the mind. The French philosopher René Descartes (1596–1650) offered a very influential version of substance dualism in his 1641 work Meditations on First Philosophy. In that work, Descartes referred to the mind as a thinking thing (res cogitans) and the body as an extended nonthinking thing (res extensa). Descartes associated identity with the thinking thing. He introduced a model in which the self and the mind were eternal.
Behaviorism
There is a response that rejects the idea of an independent mind. Within this approach, what is important is not mental states or the existence of a mind as a sort of central processor, but activity that can be translated into statements concerning observable behavior (Palmer 2016, 122). As within most philosophical perspectives, there are many different “takes” on the most correct understanding. Behaviorism is no exception. The “hard” behaviorist asserts that there are no mental states. You might consider this perspective the purist or “die-hard” perspective. The “soft” behaviorist, the moderate position, does not deny the possibility of minds and mental events but believes that theorizing concerning human activity should be based on behavior.
Before dismissing the view, pause and consider the plausibility of the position. Do we ever really know another’s mind? There is some validity to the notion that we ought to rely on behavior when trying to know or to make sense of the “other.” But if you have a toothache, and you experience myself being aware of the qualia associated with a toothache (e.g., pain, swelling, irritability, etc.), are these sensations more than activities? What of the experience that accompanies the experience?
