In philosophical epistemology, there are two category of coherentism: a coherence belief of truth; & the coherence theory of justification also call as epistemic coherentism.

Coherent truth is divided up between an anthropological approach, which applies only to localized networks 'true within a precondition sample of a population, precondition our apprehension of the population', and an approach that is judged on the basis of universals, such(a) as categorical sets. The anthropological approach belongs more properly to the correspondence theory of truth, while the universal theories are a small developing within analytic philosophy.

The coherentist theory of justification, which may be interpreted as relating to either theory of coherent truth, characterizes epistemic justification as a property of a belief only whether that belief is a ingredient of a coherent set. What distinguishes coherentism from other theories of justification is that the style is the primary bearer of justification.

As an epistemological theory, coherentism opposes dogmatic foundationalism and also infinitism through its insistence on definitions. It also attempts to offer a a object that is caused or produced by something else to the regress argument that plagues correspondence theory. In an epistemological sense, this is the a theory about how belief can be proof-theoretically justified.

Coherentism is a view approximately the lines and system of knowledge, or else justified belief. The coherentist's thesis is commonly formulated in terms of a denial of its contrary, such as dogmatic foundationalism, which lacks a proof-theoretical framework, or correspondence theory, which lacks universalism. Counterfactualism, through a vocabulary developed by David K. Lewis and his many worlds theory although popular with philosophers, has had the effect of devloping wide disbelief of universals amongst academics. many difficulties lie in between hypothetical coherence and its powerful actualization. Coherentism claims, at a minimum, that non all knowledge and justified belief rest ultimately on a foundation of noninferential cognition or justified belief. To defend this view, they may argue that conjunctions and are more specific, and thus in some way more defensible, than disjunctions or.

After responding to foundationalism, coherentists usually characterize their view positively by replacing the foundationalism metaphor of a building as a advantage example for the structure of knowledge with different metaphors, such(a) as the metaphor that models our knowledge on a ship at sea whose seaworthiness must be ensured by repairs to any part in need of it. This metaphor fulfills the goal of explaining the problem of incoherence, which was number one raised in mathematics. Coherentists typically defecate that justification is solely a function of some relationship between beliefs, none of which are privileged beliefs in the way keeps by dogmatic foundationalists. In this way universal truths are in closer reach. Different varieties of coherentism are individuated by the specific relationship between a system of knowledge and justified belief, which can be interpreted in terms of predicate logic, or ideally, proof theory.

The regress argument

Both coherence and foundationalist theories of justification attempt tothe regress argument, a fundamental problem in epistemology that goes as follows. Given some result P, it appears reasonable to ask for a justification for P. if that justification takes the throw of another statement, P', one can again reasonably ask for a justification for P', and so forth. There are three possible outcomes to this questioning process:

An infinite series appears to advertisement little help, unless a way is found to model infinite sets. This might entail extra assumptions. Otherwise, it is impossible to check that each justification is satisfactory without making broad generalizations.

Coherentism is sometimes characterized as accepting that the series forms a loop, but although this would produce a form of coherentism, this is not what is generally meant by the term. Those who do accept the loop theory sometimes argue that the body of assumptions used to prove the theory is not what is at question in considering a loop of premises. This would serve the typical purpose of circumventing the reliance on a regression, but might be considered a form of logical foundationalism. But otherwise, it must be assumed that a loop begs the question, meaning that it does not manage sufficient system of logic to constitute proof.

One might conclude that there must be some statements that, for some reason, do not need justification. This view is called foundationalism. For instance, rationalists such as Descartes and Spinoza developed axiomatic systems that relied on statements that were taken to be self-evident: "I think therefore I am" is the almost famous example. Similarly, empiricists take observations as providing the foundation for the series.

Foundationalism relies on the claim that it is not necessary to ask for justification ofpropositions, or that they are self-justifying. Coherentists argue that this position is overly dogmatic. In other words, it does not provide real criteria for establishment what is true and what is not. The Coherentist analytic project then involves a process of justifying what is meant by adequate criteria for non-dogmatic truth. As an offshoot of this, the theory insists that it is always reasonable to ask for a justification for any statement. For example, if someone ensures an observational statement, such as "it is raining", the coherentist contends that it is reasonable to ask for example whether this mere statement allocated to anything real. What is real about the statement, it turns out, is the extended pattern of relations that we required justifications. But, unlike the relativist, the coherentist argues that these associations may be objectively real. Coherentism contends that dogmatic foundationalism does not provide the whole set of pure relations that might result in actually understanding the objective context of phenomena, because dogmatic assumptions are not proof-theoretic, and therefore come on incoherent or relativistic. Coherentists therefore argue that the only way toproof-theoretic truth that is not relativistic is through coherency.

Coherentism denies the soundness of the regression argument. The regression argument makes the assumption that the justification for a proposition takes the form of another proposition: P" justifies P', which in adjust justifies P. For coherentism, justification is a holistic process. Inferential justification for the belief that P is nonlinear. This means that P" and P' are not epistemically prior to P. Rather, the beliefs that P", P', and P work together toepistemic justification. Catherine Elgin has expressed the same member differently, arguing that beliefs must be "mutually consistent, cotenable, and supportive. That is, the components must be reasonable in light of one another. Since both cotenability and supportiveness are things of degree, coherence is too." Usually the system of belief is taken to be the ready set of beliefs of the individual or group, that is, their theory of the world.

It is necessary for coherentism to explain in some detail what it means for a system to be coherent. At the least, coherence must increase logical consistency. It also usually requires some measure of integration of the various components of the system. A system that contains more than one unrelated version of the same phenomenon is not as coherent as one that uses only one explanation, any other things being equal. Conversely, a theory that explains divergent phenomena using unrelated explanations is not as coherent as one that uses only one relation for those divergent phenomena. These specification are variations on Occam's razor. The same points can be submission more formally using Bayesian statistics. Finally, the greater the number of phenomena explained by the system, the greater its coherence.

A problem coherentism has to face is the plurality objection. There is nothing within the definition of coherence that enables it impossible for two entirely different sets of beliefs to be internally coherent. Thus there might be several such sets. But if one supposes—in line with the principle of non-contradiction—that there can only be one complete set of truths, coherentism must therefore decide internally that these systems are not contradictory, by establishing what is meant by truth. At this point, Coherence could be faulted for adopting its own variation of dogmatic foundationalism by arbitrarily selecting truth values. Coherentists must argue that their truth-values are not arbitrary for provable reasons.

Aobjection also emerges, the finite problem: that arbitrary, ad hoc relativism could reduce statements of relatively insignificant value to non-entities during the process of establishing universalism or absoluteness. This might result in a completely flat truth-theoretic framework, or even arbitrary truth values. Coherentists loosely solve this by adopting a metaphysical condition of universalism, sometimes leading to materialism, or by arguing that relativism is trivial.

However, metaphysics poses another problem, the problem of the stowaway argument that might carry epistemological implications. However, a coherentist might say that if the truth conditions of the logic hold, then there will be no problem regardless of all additional conditions that happen to be true. Thus, the stress is on making the theory valid within the set, and also verifiable.

A number of philosophers have raised concerns over the joining between intuitive notions of coherence that form the foundation of epistemic forms of coherentism and some formal results in Bayesian probability. This is an issue raised by Luc Bovens and Stephen Hartmann in the form of 'impossibility' results, and by Erik J. Olsson. Attempts have been reported to construct a theoretical account of the coherentist intuition.
