Contents

Nagel is well known for his critique of material reductionist accounts of the mind, particularly in his essay "What Is It Like to Be a Bat?" (1974), and for his contributions to deontological and liberal moral and political theory in The Possibility of Altruism (1970) and subsequent writings. He continued the critique of reductionism in Mind and Cosmos (2012), in which he argues against the neo-Darwinian view of the emergence of consciousness.

Nagel was born in Belgrade, Yugoslavia (now Serbia), to German Jewish refugees [4] Carolyn (Baer) and Walter Nagel. [5] Nagel arrived in the US in 1939, and was raised in, and around New York. [4] He had no religious upbringing, but regards himself as a Jew. [6]

Nagel received a BA in philosophy from Cornell University in 1958, where he was a member of the Telluride House and where he was introduced to the philosophy of Ludwig Wittgenstein. He then attended the University of Oxford on a Fulbright Scholarship and received a BPhil in 1960; while there, he studied with J. L. Austin, and H. Paul Grice. He received his PhD in philosophy from Harvard University in 1963. [2] [7] At Harvard, Nagel studied under John Rawls, whom Nagel later called "the most important political philosopher of the twentieth century." [8]

Nagel taught at the University of California, Berkeley (from 1963 to 1966) and at Princeton University (from 1966 to 1980), where he trained many well-known philosophers including Susan Wolf, Shelly Kagan, and Samuel Scheffler, the latter of whom is now his colleague at NYU.

Nagel is a Fellow of the American Academy of Arts and Sciences and a Corresponding Fellow of the British Academy, and, in 2006, was elected as a member of the American Philosophical Society. [9] He has held a fellowship from the Guggenheim Foundation, the National Science Foundation, and the National Endowment for the Humanities. [9] In 2008, he was awarded a Rolf Schock Prize for his work in philosophy, [10] the Balzan prize, [11] and the honorary degree of Doctor of Letters from the University of Oxford. [12]

Philosophical work

Overview

Nagel began to publish philosophy at the age of twenty-two; his career now spans over fifty years of publication. Nagel thinks that each person, owing to his or her capacity to reason, instinctively seeks a unified world view. However, if this aspiration leads one to believe that there is only one way to understand our intellectual commitments, whether about the external world, knowledge, or what our practical and moral reasons ought to be, this leads one into error. For contingent, limited and finite creatures, no such unified world view is possible. That is because ways of understanding are not always better when they are more objective.

Like the British philosopher Bernard Williams, Nagel believes that the rise of modern science has permanently changed how people think of the world and our place in it. A modern scientific understanding is one way of thinking about the world and our place in it that is more objective than the common sense view it replaces. It is more objective because it is less dependent on our peculiarities as the kinds of thinkers that people are. Our modern scientific understanding involves the mathematicized understanding of the world represented by modern physics. Understanding this bleached out view of the world draws on our capacities as purely rational thinkers and fails to account for the specific nature of our perceptual sensibility. Nagel repeatedly returns to the distinction between "primary" and "secondary" qualities, that is, between primary qualities of objects like mass and shape, that are mathematically and structurally describable independent of our sensory apparatuses, and secondary qualities like taste and color, which depend on our sensory apparatuses.

Despite what may seem like skepticism about the objective claims of science, Nagel does not dispute that science describes the world that exists independently of us. His contention, rather, is that a given way of understanding a subject matter should not be regarded as better simply for being more objective. He argues that scientific understanding's attempt at an objective viewpoint--a "view from nowhere"--necessarily leaves out something essential when applied to the mind, which is inherently from a subjective point of view. As such, objective science is fundamentally unable to help people fully understand themselves. In "What Is it Like to Be a Bat?" and elsewhere, he writes that science cannot describe what it is like to be a thinker who conceives of the world from a particular subjective perspective.

Nagel argues that some phenomena are not best grasped from a more objective perspective. The standpoint of the thinker does not present itself to the thinker: he/she is that standpoint. One learns and uses mental concepts by being directly acquainted with one's own mind, whereas any attempt to think more objectively about mentality would abstract away from this fact. It would, of its nature, leave out what it is to be a thinker, and that, Nagel believes, would be a falsely objectifying view. Being a thinker is to have a subjective perspective on the world; if one abstracts away from this perspective one leaves out what he sought to explain.

Nagel thinks that philosophers over-impressed by the paradigm of the kind of objective understanding represented by modern science tend to produce theories of the mind that are falsely objectifying in precisely this kind of way. They are right to be impressed – modern science really is objective – but are wrong to take modern science to be the only paradigm of objectivity. The kind of understanding that science represents does not transfer to everything that people would like to understand.

As a philosophical rationalist, Nagel believes that a proper understanding of the place of mental properties in nature will involve a revolution in our understanding of both the physical and the mental, and that this is a reasonable prospect that people can anticipate in the near future. A plausible science of the mind will give an account of the stuff that underpins mental and physical properties in such a way that people will simply be able to see that it necessitates both of these aspects. Now, it seems to people that the mental and the physical are irreducibly distinct but that is not a metaphysical insight, or an acknowledgment of an irreducible explanatory gap, but simply where people are at their present stage of understanding.

Nagel's rationalism and tendency to present our human nature as a composite, structured around our capacity to reason, explains why he thinks that therapeutic or deflationary accounts of philosophy are simply complacent and that radical skepticism is, strictly speaking, irrefutable.[ clarification needed ] The therapeutic or deflationary philosopher, influenced by the later philosophy of Ludwig Wittgenstein, reconciles people to the dependence of our worldview on our "form of life". Nagel accuses Wittgenstein and American philosopher of mind and language Donald Davidson of philosophical idealism. [13] In both cases they ask people to take up an interpretative perspective to making sense of other speakers in the context of a shared, objective world. This, for Nagel, elevates contingent conditions of our make-up into criteria for that which is real. The result 'cuts the world down to size' and makes what there is dependent on what there can be interpreted to be. Nagel claims this is no better than more orthodox forms of idealism in which reality is claimed to be made up of mental items or claimed to be constitutively dependent on a form supplied by the mind.

Philosophy of mind

What is it like to be a something

Nagel is probably most widely known within the field of philosophy of mind as an advocate of the idea that consciousness and subjective experience cannot, at least with the contemporary understanding of physicalism, be satisfactorily explained using the current concepts of physics. This position was primarily discussed by Nagel in one of his most famous articles: "What is it Like to Be a Bat?" (1974). The article's title question, though often attributed to Nagel, was originally asked by Timothy M.B. Sprigge. The article was originally published in 1974 in The Philosophical Review , and has been reprinted several times, including in The Mind's I (edited by Daniel Dennett and Douglas Hofstadter), Readings in the Philosophy of Psychology (edited by Ned Block), Nagel's Mortal Questions (1979), The Nature of Mind (edited by David M. Rosenthal), and Philosophy of Mind: Classical and Contemporary Readings (edited by David J. Chalmers).

In "What is it Like to Be a Bat?", Nagel argues that consciousness has essential to it a subjective character, a what it is like aspect. He states that "an organism has conscious mental states if and only if there is something that it is like to be that organism—something it is like for the organism." [14] His critics[ who? ] have objected strongly to what they see as a misguided attempt to argue from a fact about how one represents the world (trivially, one can only do so from his own point of view) to a false claim about the world, that it somehow has first personal perspectives built into it. On that understanding, Nagel is a conventional dualist about the physical and the mental. This is, however, a misunderstanding[ according to whom? ]: Nagel's point is that there is a constraint on what it is to possess the concept of a mental state, namely, that one be directly acquainted with it. Concepts of mental states are only made available to a thinker who can be acquainted with his/her own states; clearly, the possession and use of physical concepts has no corresponding constraint.

Part of the puzzlement here is because of the limitations of imagination: influenced by his Princeton colleague, Saul Kripke, Nagel believes that any type identity statement that identified a physical state type with a mental state type would be, if true, necessarily true. But Kripke argues that one can easily imagine a situation where, for example, one's C-fibres are stimulated but one is not in pain and so refute any such psychophysical identity from the armchair. (A parallel argument does not hold for genuine theoretical identities.) This argument that there will always be an explanatory gap between an identification of a state in mental and physical terms is compounded, Nagel argues, by the fact that imagination operates in two distinct ways. When asked to imagine sensorily, one imagines C-fibres being stimulated; if asked to imagine sympathetically, one puts oneself in a conscious state resembling pain. These two ways of imagining the two terms of the identity statement are so different that there will always seem to be an explanatory gap, whether or not this is the case. (Some philosophers of mind[ who? ] have taken these arguments as helpful for physicalism on the grounds that it exposes a limitation that makes the existence of an explanatory gap seem compelling, while others[ who? ] have argued that this makes the case for physicalism even more impossible as it cannot be defended even in principle.)

Nagel is not a physicalist because he does not believe that an internal understanding of mental concepts shows them to have the kind of hidden essence that underpins a scientific identity in, say, chemistry. But his skepticism is about current physics: he envisages in his most recent work that people may be close to a scientific breakthrough in identifying an underlying essence that is neither physical (as people currently think of the physical), nor functional, nor mental, but such that it necessitates all three of these ways in which the mind "appears" to us. The difference between the kind of explanation he rejects and those that he accepts depends on his understanding of transparency: from his earliest paper to his most recent Nagel has always insisted that a prior context is required to make identity statements plausible, intelligible and transparent.

Natural selection and consciousness

In his 2012 book Mind and Cosmos, Nagel argues against a materialist view of the emergence of life and consciousness, writing that the standard neo-Darwinian view flies in the face of common sense. [15] :5–6 He writes that mind is a basic aspect of nature, and that any philosophy of nature that cannot account for it is fundamentally misguided. [15] :16ff He argues that the principles that account for the emergence of life may be teleological, rather than materialist or mechanistic. [15] :10 Despite Nagel's being an atheist and not a proponent of intelligent design (ID), his book was "praised by creationists", according to the New York Times . [2] Nagel writes in Mind and Cosmos that he disagrees with both ID defenders and their opponents, who argue that the only naturalistic alternative to ID is the current reductionist neo-Darwinian model. [15] :12

Nagel has argued that ID should not be rejected as non-scientific, for instance writing in 2008 that "ID is very different from creation science," and that the debate about ID "is clearly a scientific disagreement, not a disagreement between science and something else." [16] In 2009, he recommended Signature in the Cell by the philosopher and ID proponent Stephen C. Meyer in The Times Literary Supplement as one of his "Best Books of the Year." [17] Nagel does not accept Meyer's conclusions but he endorsed Meyer's approach, and argued in Mind and Cosmos that Meyer and other ID proponents, David Berlinski and Michael Behe, "do not deserve the scorn with which they are commonly met." [15] :10

Steven Pinker and Daniel Dennett both dismissed the book. [18]

Ethics

Nagel's Rawlsian approach

Nagel has been highly influential in the related fields of moral and political philosophy. Supervised by John Rawls, Nagel has been a long-standing proponent of a Kantian and rationalist approach to moral philosophy. His distinctive ideas were first presented in the short monograph The Possibility of Altruism, published in 1970. That book seeks by reflection on the nature of practical reasoning to uncover the formal principles that underlie reason in practice and the related general beliefs about the self that are necessary for those principles to be truly applicable to us. Nagel defends motivated desire theory about the motivation of moral action. According to motivated desire theory, when a person is motivated to moral action it is indeed true that such actions are motivated – like all intentional actions – by a belief and a desire. But it is important to get the justificatory relations right: when a person accepts a moral judgment he or she is necessarily motivated to act. But it is the reason that does the justificatory work of justifying both the action and the desire. Nagel contrasts this view with a rival view which believes that a moral agent can only accept that he or she has a reason to act if the desire to carry out the action has an independent justification. An account based on presupposing sympathy would be of this kind. [19]

The most striking claim of the book is that there is a very close parallel between prudential reasoning in one's own interests and moral reasons to act to further the interests of another person. When one reasons prudentially, for example about the future reasons that one will have, one allows the reason in the future to justify one's current action without reference to the strength of one's current desires. If a hurricane were to destroy someone's car next year at that point he will want his insurance company to pay him to replace it: that future reason gives him a reason, now, to take out insurance. The strength of the reason ought not to be hostage to the strength of one's current desires. The denial of this view of prudence, Nagel argues, means that one does not really believe that one is one and the same person through time. One is dissolving oneself into distinct person-stages. [20]

Altruistic action

This is the basis of his analogy between prudential actions and moral actions: in cases of altruistic action for another person's good that person's reasons quite literally become reasons for one if they are timeless and intrinsic reasons. Genuine reasons are reasons for anyone. Comparable to the views of the nineteenth century moral philosopher Henry Sidgwick, Nagel believes that one needs to conceive of one's good as an impersonal good and one's reasons as objective reasons. That means, practically, that a timeless and intrinsic value generates reasons for anyone. A person who denies the truth of this claim is committed, as in the case of a similar mistake about prudence, to a false view of him or herself. In this case the false view is that one's reasons are irreducibly his, in a way that does not allow them to be reasons for anyone: Nagel argues this commits such a person to the view that he or she cannot make the same judgments about her own reasons third-personally that she can make first-personally. Nagel calls this "dissociation" and considers it a practical analogue of solipsism (the philosophical idea that only one's own mind is sure to exist). Once again, a false view of what is involved in reasoning properly is refuted by showing that it leads to a false view of the nature of people.

Subjective and objective reasons

Nagel's later work on ethics ceases to place as much weight on the distinction between a person's personal or "subjective" reasons and his or her "objective" reasons. Earlier, in The Possibility of Altruism, he took the stance that if one's reasons really are about intrinsic and timeless values then, qua subjective reason, one can only take them to be the guise of the reasons that there really are – the objective ones. In later discussions, Nagel treats his former view as an incomplete attempt to convey the fact that there are distinct classes of reasons and values, and speaks instead of "agent-relative" and "agent-neutral" reasons. In the case of agent-relative reasons (the successor to subjective reasons) specifying the content of the reason makes essential reference back to the agent for whom it is a reason. An example of this might be: "Anyone has a reason to honor his or her parents." By contrast, in the case of agent-neutral reasons (the successor to objective reasons) specifying the content of the reason does not make any essential reference back to the person for whom it is a reason. An example of this might be: "Anyone has a reason to promote the good of parenthood."

Objective reasons

The different classes of reasons and values (i.e., agent-relative and agent-neutral) emphasized in Nagel's later work are situated within a Sidgwickian model in which one's moral commitments are thought of objectively, such that one's personal reasons and values are simply incomplete parts of an impersonal whole. The structure of Nagel's later ethical view is that all reasons must be brought into relation to this objective view of oneself. Those reasons and values that withstand detached critical scrutiny are objective, but more subjective reasons and values can nevertheless be objectively tolerated. However, the most striking part of the earlier argument and of Sidgwick's view is preserved: agent-neutral reasons are literally reasons for anyone, so all objectifiable reasons become individually possessed no matter whose they are. Thinking reflectively about ethics from this standpoint, one must take every other agent's standpoint on value as seriously as one's own, since one's own perspective is just a subjective take on an inter-subjective whole; one's personal set of reasons is thus swamped by the objective reasons of all others.

World agent views

This is similar to "world agent" consequentialist views in which one takes up the standpoint of a collective subject whose reasons are those of everyone. But Nagel remains an individualist who believes in the separateness of persons so his task is to explain why this objective viewpoint does not swallow up the individual standpoint of each of us. He provides an extended rationale for the importance to people of their personal point of view. The result is a hybrid ethical theory of the kind defended by Nagel's Princeton PhD student Samuel Scheffler in The Rejection of Consequentialism. The objective standpoint and its demands have to be balanced with the subjective personal point of view of each person and its demands. One can always be maximally objective but one does not have to be. One can legitimately "cap" the demands placed on him by the objective reasons of others. In addition, in his later work, Nagel finds a rationale for so-called deontic constraints in a way Scheffler could not. Following Warren Quinn and Frances Kamm, Nagel grounds them on the inviolability of persons.

Political philosophy

The extent to which one can lead a good life as an individual while respecting the demands of others leads inevitably to political philosophy. In the Locke lectures published as the book Equality and Partiality, Nagel exposes John Rawls's theory of justice to detailed scrutiny. Once again, Nagel places such weight on the objective point of view and its requirements that he finds Rawls's view of liberal equality not demanding enough. Rawls's aim to redress, not remove, the inequalities that arise from class and talent seems to Nagel to lead to a view that does not sufficiently respect the needs of others. He recommends a gradual move to much more demanding conceptions of equality, motivated by the special nature of political responsibility. Normally people draw a distinction between that which people do and that which people fail to bring about. But this thesis, true of individuals, does not apply to the state, which is a collective agent. A Rawlsian state permits intolerable inequalities and people need to develop a more ambitious view of equality to do justice to the demands of the objective recognition of the reasons of others. For Nagel, honoring the objective point of view demands nothing less.

Atheism

In his work Mind and Cosmos, Nagel notes that he is an atheist, writing, "I lack the sensus divinitatis that enablesindeed compelsso many people to see in the world the expression of divine purpose as naturally as they see in a smiling face the expression of human feeling." [15] He also said in his book The Last Word, I want atheism to be true and am made uneasy by the fact that some of the most intelligent and well-informed people I know are religious believers. It isn't just that I don't believe in God and, naturally, hope that I'm right in my belief." [21] .

Experience itself as a good

Nagel has said that "There are elements which, if added to one's experience, make life better; there are other elements which if added to one's experience, make life worse. But what remains when these are set aside is not merely neutral: it is emphatically positive.... The additional positive weight is supplied by experience itself, rather than by any of its consequences." [22] [23]

Awards

Nagel received the 1996 PEN/Diamonstein-Spielvogel Award for the Art of the Essay for Other Minds (1995). He has also been awarded the Balzan Prize in Moral Philosophy (2008), the Rolf Schock Prize in Logic and Philosophy of the Royal Swedish Academy of Sciences (2008) and the Distinguished Achievement Award of the Mellon Foundation (2006).

Idealism philosophical view that reality is immaterial

In philosophy, idealism is the diverse group of metaphysical philosophies which assert that "reality" is in some way indistinguishable or inseparable from human understanding and/or perception; that it is in some sense mentally constituted, or otherwise closely connected to ideas. According to Immanuel Kant, a pioneer of modern idealist thought, idealism does “not concern the existence of things”, but asserts only that our “modes of representation” of them, above all space and time, are not “determinations that belong to things in themselves” but essential features of our own minds. Kant called this position “transcendental” and “critical” idealism, since it describes the way in which "reality" is utterly transcended by, and cannot be thought separate from, the categories with which they are structered by and in human understanding.

A subject is a being who has a unique consciousness and/or unique personal experiences, or an entity that has a relationship with another entity that exists outside itself.

Moral relativism may be any of several philosophical positions concerned with the differences in moral judgments across different people and cultures. Descriptive moral relativism holds only that some people do in fact disagree about what is moral; meta-ethical moral relativism holds that in such disagreements, nobody is objectively right or wrong; and normative moral relativism holds that because nobody is right or wrong, we ought to tolerate the behavior of others even when we disagree about the morality of it.

John Rawls American political philosopher

John Bordley Rawls was an American moral and political philosopher in the liberal tradition. Rawls received both the Schock Prize for Logic and Philosophy and the National Humanities Medal in 1999, the latter presented by President Bill Clinton, in recognition of how Rawls' work "helped a whole generation of learned Americans revive their faith in democracy itself."

Mind–body dualism Philosophical theory that mental phenomena are non-physical and that matter exists independently of mind

Mind–body dualism is the view in the philosophy of mind that mental phenomena are non-physical, or that the mind and body are distinct and separable. Thus, it encompasses a set of views about the relationship between mind and matter, and between subject and object, and is contrasted with other positions, such as physicalism and enactivism, in the mind–body problem.

John Henry McDowell is a South African philosopher, formerly a fellow of University College, Oxford and now University Professor at the University of Pittsburgh. Although he has written extensively on metaphysics, epistemology, ancient philosophy, and meta-ethics, McDowell's most influential work has been in the philosophy of mind and philosophy of language. McDowell was one of three recipients of the 2010 Andrew W. Mellon Foundation's Distinguished Achievement Award, and is a Fellow of both the American Academy of Arts & Sciences and the British Academy.

Eliminative materialism Philosophical view that states-of-mind as commonly understood do not exist

Eliminative materialism is the claim that people's common-sense understanding of the mind is false and that certain classes of mental states that most people believe in do not exist. It is a materialist position in the philosophy of mind. Some supporters of eliminativism argue that no coherent neural basis will be found for many everyday psychological concepts such as belief or desire, since they are poorly defined. Rather, they argue that psychological concepts of behaviour and experience should be judged by how well they reduce to the biological level. Other versions entail the non-existence of conscious mental states such as pain and visual perceptions.

Panpsychism View that mind or a mind-like aspect is a fundamental and ubiquitous feature of reality

In philosophy of mind, panpsychism is the view that mind or a mind-like aspect is a fundamental and ubiquitous feature of reality. It has taken on a wide variety of forms. Contemporary academic proponents hold that sentience or subjective experience is ubiquitous, while distancing these qualities from complex human mental attributes; they ascribe a primitive form of mentality to entities at the fundamental level of physics but do not ascribe it to most aggregates, such as rocks or buildings. On the other hand, some historical theorists ascribed attributes such as life or spirits to all entities.

Colin McGinn is a British philosopher. He has held teaching posts and professorships at University College London, the University of Oxford, Rutgers University and the University of Miami.

The hard problem of consciousness is the problem of explaining why and how sentient organisms have qualia or phenomenal experiences—how and why it is that some internal states are felt states, such as heat or pain, rather than unfelt states, as in a thermostat or a toaster. The philosopher David Chalmers, who introduced the term "hard problem" of consciousness, contrasts this with the "easy problems" of explaining the ability to discriminate, integrate information, report mental states, focus attention, and so forth. Easy problems are (relatively) easy because all that is required for their solution is to specify a mechanism that can perform the function. That is, regardless of how complex or poorly understood the phenomena of the easy problems may be, they can eventually be understood by relying entirely on standard scientific methodologies. Chalmers claims that the problem of experience is distinct from this set and will "persist even when the performance of all the relevant functions is explained".

The subjective character of experience is a term in psychology and the philosophy of mind denoting that all subjective phenomena are associated with a single point of view ("ego"). The term was coined and illuminated by Thomas Nagel in his famous paper "What Is it Like to Be a Bat?"

In metaphysics, realism about a given object is the view that this object exists in reality independently of our conceptual scheme. In philosophical terms, these objects are ontologically independent of someone's conceptual scheme, perceptions, linguistic practices, beliefs, etc.

Kantian ethics Ethical theory of Immanuel Kant

Kantian ethics refers to a deontological ethical theory ascribed to the German philosopher Immanuel Kant. The theory, developed as a result of Enlightenment rationalism, is based on the view that the only intrinsically good thing is a good will; an action can only be good if its maxim—the principle behind it—is duty to the moral law. Central to Kant's construction of the moral law is the categorical imperative, which acts on all people, regardless of their interests or desires. Kant formulated the categorical imperative in various ways. His principle of universalizability requires that, for an action to be permissible, it must be possible to apply it to all people without a contradiction occurring. Kant's formulation of humanity, the second section of the Categorical Imperative, states that as an end in itself humans are required never to treat others merely as a means to an end, but always, additionally, as ends in themselves. The formulation of autonomy concludes that rational agents are bound to the moral law by their own will, while Kant's concept of the Kingdom of Ends requires that people act as if the principles of their actions establish a law for a hypothetical kingdom. Kant also distinguished between perfect and imperfect duties. A perfect duty, such as the duty not to lie, always holds true; an imperfect duty, such as the duty to give to charity, can be made flexible and applied in particular time and place.

What Is It Like to Be a Bat? paper by Thomas Nagel

"What Is It Like to Be a Bat?" is a paper by American philosopher Thomas Nagel, first published in The Philosophical Review in October 1974, and later in Nagel's Mortal Questions (1979), which presents several difficulties posed by consciousness, including the possible insolubility of the mind-body problem owing to “facts beyond the reach of human concepts”, the limits of objectivity and reductionism, the “phenomenological features” of subjective experience, the limits of human imagination, and what it means to be a particular, conscious thing. Nagel famously asserts that “an organism has conscious mental states if and only if there is something that it is like to be that organism—something it is like for the organism." This assertion has achieved special status in consciousness studies as “the standard ‘what it’s like’ locution” Daniel Dennett, while sharply disagreeing on some points, acknowledged Nagel’s paper as "the most widely cited and influential thought experiment about consciousness." Peter Hacker analyzes Nagel’s statement as not only “malconstructed” but philosophically “misconceived” as a definition of consciousness, and he asserts that Nagel’s paper “laid the groundwork for…forty years of fresh confusion about consciousness.”

Objectivity is a philosophical concept of being true independently from individual subjectivity caused by perception, emotions, or imagination. A proposition is considered to have objective truth when its truth conditions are met without bias caused by a sentient subject. Scientific objectivity refers to the ability to judge without partiality or external influence, sometimes used synonymously with neutrality.

  22. The full quotation is "... the natural view that death is an evil because it brings to an end all the goods that life contains. We need not give an account of these goods here, except to observe that some of them, like perception, desire, activity, and thought, are so general as to be constitutive of human life. They are widely regarded as formidable benefits in themselves, despite the fact that they are conditions of misery as well as of happiness, and that a sufficient quantity of more particular evils can perhaps outweigh them. That is what is meant, I think by the allegation that it is good simply to be alive, even if one is undergoing terrible experiences. The situation is roughly this: There are elements which, it added to one's experience, make life better; there are other elements which if added to one's experience, make life worse. But what remains when these are set aside is not merely neutral: it is emphatically positive. Therefore life is worth living even when the bad elements of experience are plentiful, and the good ones too meager to outweigh the bad ones on their own. The additional positive weight is supplied by experience itself, rather than by any of its consequences."

  23. Rhys Southan explains such ordinary experiences as having value "... because of the almost unbelievable fact that there is a world at all, and that we’re conscious beings who get to be in it, feelings its sensations, and interacting with it and other similarly improbable existers." http://www.oxonianreview.org/wp/the-vise-side-of-life/
