Neurath's boat (or Neurath's ship) is a simile used in anti-foundational accounts of knowledge, especially in the philosophy of science. It was first formulated by Otto Neurath. It is based in part on the Ship of Theseus which, however, is standardly used to illustrate other philosophical questions, to do with problems of identity. [1] It was popularised by Willard Van Orman Quine in Word and Object (1960).
Neurath used the simile in several occasions, [1] [2] the first being in Neurath's text "Problems in War Economics" (1913). In "Anti-Spengler" (1921) Neurath wrote:
We are like sailors who on the open sea must reconstruct their ship but are never able to start afresh from the bottom. Where a beam is taken away a new one must at once be put there, and for this the rest of the ship is used as support. In this way, by using the old beams and driftwood the ship can be shaped entirely anew, but only by gradual reconstruction. [2]
Neurath's non-foundational analogy of reconstructing piecemeal a ship at sea contrasts with Descartes' much earlier foundationalist analogy—in Discourse on the Method (1637) and Meditations on First Philosophy (1641)—of demolishing a building all at once and rebuilding from the ground up. [3] Neurath himself pointed out this contrast. [2] [4]
The boat was replaced by a raft in discussions by some philosophers, such as Paul Lorenzen in 1968, [5] Susan Haack in 1974, [6] and Ernest Sosa in 1980. [7] Lorenzen's use of the simile of the raft was a kind of foundationalist modification of Neurath's original, disagreeing with Neurath by asserting that it is possible to jump into the water and to build a new raft while swimming, i.e., to "start from scratch" to build a new system of knowledge. [5] [8]
Prior to Neurath's simile, Charles Sanders Peirce had used with similar purpose the metaphor of walking on a bog: one only takes another step when the ground beneath one's feet begins to give way. [9]
Keith Stanovich, in his book The Robot's Rebellion, refers to it as a Neurathian bootstrap, using bootstrapping as an analogy to the recursive nature of revising one's beliefs. [10] A "rotten plank" on the ship, for instance, might represent a meme virus or a junk meme (i.e., a meme that is either maladaptive to the individual, or serves no beneficial purpose for the realization of an individual's life goals). It may be impossible to bring the ship to shore for repairs, therefore one may stand on planks that are not rotten in order to repair or replace the ones that are. At a later time, the planks previously used for support may be tested by standing on other planks that are not rotten:
We can conduct certain tests assuming that certain memeplexes (e.g., science, logic, rationality) are foundational, but at a later time we might want to bring these latter memeplexes into question too. The more comprehensively we have tested our interlocking memeplexes, the more confident we can be that we have not let a meme virus enter into our mindware…. [10] : 181
In this way, people might proceed to examine and revise their beliefs so as to become more rational. [10] : 92
Epistemology is the branch of philosophy concerned with knowledge. Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Debates in (contemporary) epistemology are generally clustered around four core areas:
In philosophy, empiricism is an epistemological view which holds that true knowledge or justification comes only or primarily from sensory experience. It is one of several competing views within epistemology, along with rationalism and skepticism. Empiricism emphasizes the central role of empirical evidence in the formation of ideas, rather than innate ideas or traditions. Empiricists may argue that traditions arise due to relations of previous sensory experiences.
Foundationalism concerns philosophical theories of knowledge resting upon non-inferential justified belief, or some secure foundation of certainty such as a conclusion inferred from a basis of sound premises. The main rival of the foundationalist theory of justification is the coherence theory of justification, whereby a body of knowledge, not requiring a secure foundation, can be established by the interlocking strength of its components, like a puzzle solved without prior certainty that each small region was solved correctly.
A meme is an idea, behavior, or style that spreads by means of comedic imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme. A meme acts as a unit for carrying cultural ideas, symbols, or practices, that can be transmitted from one mind to another through writing, speech, gestures, rituals, or other imitable phenomena with a mimicked theme. Supporters of the concept regard memes as cultural analogues to genes in that they self-replicate, mutate, and respond to selective pressures. In popular language, a meme may refer to an Internet meme, typically an image, that is remixed, copied, and circulated in a shared cultural experience online.
A metaphor is a figure of speech that, for rhetorical effect, directly refers to one thing by mentioning another. It may provide clarity or identify hidden similarities between two different ideas.
Thomas Reid was a religiously trained Scottish philosopher best known for his philosophical method, his theory of perception, and its wide implications on epistemology, and as the developer and defender of an agent-causal theory of free will. He also focused extensively on ethics, theory of action and philosophy of mind.
Otto Karl Wilhelm Neurath was an Austrian-born philosopher of science, sociologist, and political economist. He was also the inventor of the ISOTYPE method of pictorial statistics and an innovator in museum practice. Before he fled his native country in 1934, Neurath was one of the leading figures of the Vienna Circle.
The analogy of the sun is found in the sixth book of The Republic (507b–509c), written by the Greek philosopher Plato as a dialogue between his brother Glaucon and Socrates, and narrated by the latter. Upon being urged by Glaucon to define goodness, a cautious Socrates professes himself incapable of doing so. Instead he draws an analogy and offers to talk about "the child of goodness". Socrates reveals this "child of goodness" to be the Sun, proposing that just as the Sun illuminates, bestowing the ability to see and be seen by the eye, with its light, so the idea of goodness illumines the intelligible with truth. While the analogy sets forth both epistemological and ontological theories, it is debated whether these are most authentic to the teaching of Socrates or its later interpretations by Plato.
Pragmatism is a philosophical tradition that views language and thought as tools for prediction, problem solving, and action, rather than describing, representing, or mirroring reality. Pragmatists contend that most philosophical topics—such as the nature of knowledge, language, concepts, meaning, belief, and science—are all best viewed in terms of their practical uses and successes.
Richard McKay Rorty was an American philosopher. Educated at the University of Chicago and Yale University, he had strong interests and training in both the history of philosophy and in contemporary analytic philosophy. Rorty's academic career included appointments as the Stuart Professor of Philosophy at Princeton University, Kenan Professor of Humanities at the University of Virginia, and Professor of Comparative literature at Stanford University. Among his most influential books are Philosophy and the Mirror of Nature (1979), Consequences of Pragmatism (1982), and Contingency, Irony, and Solidarity (1989).
In philosophical epistemology, there are two types of coherentism: the coherence theory of truth; and the coherence theory of justification.
Roderick Milton Chisholm was an American philosopher known for his work on epistemology, metaphysics, free will, value theory, and the philosophy of perception.
A pragmatic theory of truth is a theory of truth within the philosophies of pragmatism and pragmaticism. Pragmatic theories of truth were first posited by Charles Sanders Peirce, William James, and John Dewey. The common features of these theories are a reliance on the pragmatic maxim as a means of clarifying the meanings of difficult concepts such as truth; and an emphasis on the fact that belief, certainty, knowledge, or truth is the result of an inquiry.
Virtue epistemology is a current philosophical approach to epistemology that stresses the importance of intellectual and specifically epistemic virtues. Virtue epistemology evaluates knowledge according to the properties of the persons who hold beliefs in addition to or instead of the properties of the propositions and beliefs. Some advocates of virtue epistemology also adhere to theories of virtue ethics, while others see only loose analogy between virtue in ethics and virtue in epistemology.
Anti-foundationalism is any philosophy which rejects a foundationalist approach. An anti-foundationalist is one who does not believe that there is some fundamental belief or principle which is the basic ground or foundation of inquiry and knowledge.
Naturalized epistemology is a collection of philosophic views concerned with the theory of knowledge that emphasize the role of natural scientific methods. This shared emphasis on scientific methods of studying knowledge shifts focus to the empirical processes of knowledge acquisition and away from many traditional philosophical questions. There are noteworthy distinctions within naturalized epistemology. Replacement naturalism maintains that traditional epistemology should be abandoned and replaced with the methodologies of the natural sciences. The general thesis of cooperative naturalism is that traditional epistemology can benefit in its inquiry by using the knowledge we have gained from the cognitive sciences. Substantive naturalism focuses on an asserted equality of facts of knowledge and natural facts.
Neopragmatism, sometimes called post-Deweyan pragmatism, linguistic pragmatism, or analytic pragmatism, is the philosophical tradition that infers that the meaning of words is a result of how they are used, rather than the objects they represent.
Originally, fallibilism is the philosophical principle that propositions can be accepted even though they cannot be conclusively proven or justified, or that neither knowledge nor belief is certain. The term was coined in the late nineteenth century by the American philosopher Charles Sanders Peirce, as a response to foundationalism. Theorists, following Austrian-British philosopher Karl Popper, may also refer to fallibilism as the notion that knowledge might turn out to be false. Furthermore, fallibilism is said to imply corrigibilism, the principle that propositions are open to revision. Fallibilism is often juxtaposed with infallibilism.
Verificationism, also known as the verification principle or the verifiability criterion of meaning, is the philosophical doctrine which asserts that a statement is meaningful only if it is either empirically verifiable or a truth of logic.
The Quine–Putnam indispensability argument is an argument in the philosophy of mathematics for the existence of abstract mathematical objects such as numbers and sets, a position known as mathematical platonism. It was named after the philosophers Willard Quine and Hilary Putnam, and is one of the most important arguments in the philosophy of mathematics.
If we envision natural language as a ship at sea, then our situation can be described as follows: If we are unable to make landfall, then our ship must have been constructed on the high seas—not by us but by our ancestors. Our ancestors must have been able to swim and have somehow carpentered together a raft out of, say, driftwood. They then continually improved on this raft until today the raft has become a comfortable ship. So comfortable that we no longer have the courage to jump into the water and once more start from scratch. To solve the problem of the method for thought, we must put ourselves in such a shipless condition, that is, bereft of language, and then attempt to retrace the activities whereby we could, while swimming free in the middle of the sea of life, build for ourselves a raft or even a ship.
Certainly some logic is taken for granted in the presentation of the pragmatist picture. But to suppose that this shows that picture to be incoherent is to forget, what is crucial, that we are, to use Neurath's figure, rebuilding our raft while afloat on it.
The coherentists reject the metaphor of the pyramid in favor of one that they owe to the positivist Neurath, according to whom our body of knowledge is a raft that floats free of any anchor or tie. Repairs must be made afloat, and though no part is untouchable, we must stand on some in order to replace or repair others. Not every part can go at once.
Peirce's view is similar to Neurath's. Inquiry is the process of acquiring beliefs by making adjustments to our body of background belief. We revise our beliefs (and add or subtract beliefs) so as to better account for and deal with experience. ... Peirce uses a metaphor similar in spirit to Neurath's boat. Inquiry 'is not standing upon the bedrock of fact. It is walking upon a bog, and can only say, this ground seems to hold for the present. Here I will stay till it begins to give way.' (CP 5.589)
