Mental substance

In another concept of mind, the set of cognitive faculties are considered to consist of an immaterial substance, separate from and independent of the body. If a person is then identified with their mind, rather than their body—if a person is conside... red to be their mind—and their mind is such a non-physical substance, then personal identity over time may be grounded in the persistence of this non-physical substance, despite the continuous change in the substance of the body it is associated with. The mind-body problem concerns the explanation of the relationship, if any, that exists between minds, or mental processes, and bodily states or processes. One of the aims of philosophers who work in this area is to explain how a non-material mind can influence a material body and vice versa. However, this is not uncontroversial or unproblematic, and adopting it as a solution raises questions. Perceptual experiences depend on stimuli which arrive at various sensory organs from the external world and these stimuli cause changes in mental states; ultimately causing sensation.[note 12] A desire for food, for example, will tend to cause a person to move their body in a manner and in a direction to obtain food. The question, then, is how it can be possible for conscious experiences to arise out of an organ (the human brain) possessing electrochemical properties. A related problem is to explain how propositional attitudes (e.G. Beliefs and desires) can cause neurons of the brain to fire and muscles to contract in the correct manner. These comprise some of the puzzles that have confronted epistemologists and philosophers of mind from at least the time of René Descartes   more

Locke's conception

John Locke considered personal identity (or the self) to be founded on consciousness (viz. Memory), and not on the substance of either the soul or the body. Book II Chapter XXVII entitled "On Identity and Diversity" in An Essay Concerning Human Unde... rstanding (1689) has been said to be one of the first modern conceptualizations of consciousness as the repeated self-identification of oneself. Through this identification, moral responsibility could be attributed to the subject and punishment and guilt could be justified, as critics such as Nietzsche would point out. According to Locke, personal identity (the self) "depends on consciousness, not on substance" nor on the soul. We are the same person to the extent that we are conscious of the past and future thoughts and actions in the same way as we are conscious of present thoughts and actions. If consciousness is this "thought" which "goes along with the substance ... Which makes the same person", then personal identity is only founded on the repeated act of consciousness: "This may show us wherein personal identity consists: not in the identity of substance, but... In the identity of consciousness". For example, one may claim to be a reincarnation of Plato, therefore having the same soul substance. However, one would be the same person as Plato only if one had the same consciousness of Plato's thoughts and actions that he himself did. Therefore, self-identity is not based on the soul. One soul may have various personalities. Neither is self-identity founded on the body substance, argues Locke, as the body may change while the person remains the same. Even the identity of animals is not founded on their body: "animal identity is preserved in identity of life, and not of substance", as the body of the animal grows and changes during its life. On the other hand, identity of humans is based on their consciousness. But this interesting border-case leads to this problematic thought that since personal identity is based on consciousness, and that only oneself can be aware of his consciousness, exterior human judges may never know if they really are judging – and punishing – the same person, or simply the same body. In other words, Locke argues that may be judged only for the acts of the body, as this is what is apparent to all but God; however, are in truth only responsible for the acts for which are conscious   more

Bodily substance

One concept of personal persistence over time is simply to have continuous bodily existence. However, as the Ship of Theseus problem illustrates, even for inanimate objects there are difficulties in determining whether one physical body at one time ... is the same thing as a physical body at another time. With humans, over time our bodies age and grow, losing and gaining matter, and over sufficient years will not consist of most of the matter they once consisted of. It is thus problematic to ground persistence of personal identity over time in the continuous existence of our bodies. Nevertheless, this approach has its supporters which define humans as a biological organism and asserts the proposition that a psychological relation is not necessary for personal continuity. This personal identity ontology assumes the relational theory[9] of life-sustaining processes instead of bodily continuity. Derek Parfit presents a thought experiment designed to bring out intuitions about the corporeal continuity. This thought experiment discusses cases in which a person is teletransported from Earth to Mars. Ultimately, the inability to specify where on a spectrum does the transmitted person stop being identical to the initial person on Earth appears to show that having a numerically identical physical body is not the criterion for personal identit   more

Philosophical intuition

Bernard Williams presents a thought experiment appealing to the intuitions about what it is to be the same person in the future. The thought experiment consists of two approaches to the same experiment. For the first approach Williams suggests that...  suppose that there is some process by which subjecting two persons to it can result in the two persons have “exchanged” bodies. The process has put into the body of person B the memories, behavioral dispositions, and psychological characteristics of the person who prior to undergoing the process belonged to person A; and conversely with person B. To show this one is to suppose that before undergoing the process person A and B are asked to which resulting person, A-Body-Person or B-Body-Person, they wish to receive a punishment and which a reward. Upon undergoing the process and receiving either the punishment or reward, it appears to that A-Body-Person expresses the memories of choosing who gets which treatment as if that person was person B; conversely with B-Body-Person. This sort of approach to the thought experiment appears to show that since the person who expresses the psychological characteristics of person A to be person A, then intuition is that psychological continuity is the criterion for personal identity. The second approach is to suppose that someone is told that one will have memories erased and then one will be tortured. Does one need to be afraid of being tortured? The intuition is that people will be afraid of being tortured, since it will still be one despite not having one's memories. Next, Williams asked one to consider several similar scenarios. Intuition is that in all the scenarios one is to be afraid of being tortured, that it is still one's self despite having one's memories erased and receiving new memories. However, the last scenario is an identical scenario to the one in the first scenario   more

Psychological continuity

In psychology, personal continuity, also called personal persistence, is the uninterrupted connection concerning a particular person of his or her private life and personality. Personal continuity is the union affecting the facets arising from perso... nality in order to avoid discontinuities from one moment of time to another time. Personal continuity is an important part of identity; this is the process of ensuring that the qualities of the mind, such as self-awareness, sentience, sapience, and the ability to perceive the relationship between oneself and one's environment, are consistent from one moment to the next. Personal continuity is the property of a continuous and connected period of time and is intimately related to do with a person's body or physical being in a single four-dimensional continuum. Associationism, a theory of how ideas combine in the mind, allows events or views to be associated with each other in the mind, thus leading to a form of learning. Associations can result from contiguity, similarity, or contrast. Through contiguity, one associates ideas or events that usually happen to occur at the same time. Some of these events form an autobiographical memory in which each is a personal representation of the general or specific events and personal facts. Ego integrity is the psychological concept of the ego's accumulated assurance of its capacity for order and meaning. Ego identity is the accrued confidence that the inner sameness and continuity prepared in the past are matched by the sameness and continuity of one's meaning for others, as evidenced in the promise of a career. Body and ego control organ expressions. And of the other attributes of the dynamics of a physical system to face the emotions of ego deathin circumstances which can summon, sometimes anti-theonymistic, self-abandonment   more

The bundle theory of the self

David Hume undertook looking at the mind–body problem. Hume also investigated a person's character, the relationship between human and animal nature, and the nature of agency. Hume pointed out that we tend to think that we are the same person we wer... e five years ago. Though we've changed in many respects, the same person appears present as was present then. We might start thinking about which features can be changed without changing the underlying self. Hume, however, denies that there is a distinction between the various features of a person and the mysterious self that supposedly bears those features. When we start introspecting, "we are never intimately conscious of anything but a particular perception; man is a bundle or collection of different perceptions which succeed one another with an inconceivable rapidity and are in perpetual flux and movement". It is plain that in the course of our thinking, and in the constant revolution of our ideas, our imagination runs easily from one idea to any other that resembles it, and that this quality alone is to the fancy a sufficient bond and association. It is likewise evident that as the senses, in changing their objects, are necessitated to change them regularly, and take them as they lie contiguous to each other, the imagination must by long custom acquire the same method of thinking, and run along the parts of space and time in conceiving its objects. Note in particular that, in Hume's view, these perceptions do not belong to anything. Hume, similar to the Buddha, compares the soul to a commonwealth, which retains its identity not by virtue of some enduring core substance, but by being composed of many different, related, and yet constantly changing elements. The question of personal identity then becomes a matter of characterizing the loose cohesion of one's personal experience. In short, what matters for Hume is not that 'identity' exists but that the relations of causation, contiguity, and resemblances obtain among the perceptions. Critics of Hume state in order for the various states and processes of the mind to seem unified, there must be something which perceives their unity, the existence of which would be no less mysterious than a personal identity. Hume solves this by considering substance as engendered by the togetherness of its properties   more

The no-self theory

The "no-self theory" holds that the self cannot be reduced to a bundle because the concept of a self is incompatible with the idea of a bundle. Propositionally, the idea of a bundle implies the notion of bodily or psychological relations that do not...  in fact exist. James Giles, a principal exponent of this view, argues that the no-self or eliminativist theory and the bundle or reductionist theory agree about the non-existence of a substantive self. The reductionist theory, according to Giles, mistakenly resurrects the idea of the self in terms of various accounts about psychological relations. The no-self theory, on the other hand, "lets the self lie where it has fallen". This is because the no-self theory rejects all theories of the self, even the bundle theory. On Giles' reading, Hume is actually a no-self theorist and it is a mistake to attribute to him a reductionist view like the bundle theory. Hume's assertion that personal identity is a fiction supports this reading, according to Giles. The Buddhist view of personal identity is also a no-self theory rather than a reductionist theory, because the Buddha rejects attempts to reconstructions in terms of consciousness, feelings, or the body in notions of an eternal, unchanging Self. According to this line of criticism, the sense of self is an evolutionary artifact, which saves time in the circumstances it evolved for. But sense of self breaks down when considering some events such as memory loss, split personality disorder, brain damage, brainwashing, and various thought experiments. When presented with imperfections in the intuitive sense of self and the consequences to this concept which rely on the strict concept of self, a tendency to mend the concept occurs, possibly because of cognitive dissonance   more
