challenges traditional views of knowledge, proposing a web-like structure instead of a linear foundation. It suggests our beliefs form an interconnected network, where each idea supports and is supported by others. This approach tackles the in epistemology by allowing .
Critics argue coherentism might justify false but consistent belief systems. However, proponents stress the importance of empirical coherence. The debate continues over whether coherentism provides sufficient justification for knowledge claims, highlighting the ongoing evolution of epistemological theories.

- necessary but not sufficient for justification
- with established facts also important
Inferential Relationships and Belief Evaluation

- often employ to justification
- used to update belief probabilities based on new evidence
- Coherence measured as function of probabilistic relationships between beliefs
Belief Dynamics
Belief Revision and System Maintenance

- guides belief revision
- Preserve as much of existing belief system as possible
- Make smallest changes necessary to accommodate new evidence

- Truth seen as ideal coherent system that explains all phenomena
- Critics question whether coherence alone guarantees truth
- Ongoing debate over relationship between coherence and truth in epistemology
- Some argue for additional criteria beyond coherence (correspondence to reality)
- Others contend coherence itself is best available proxy for truth
Key Terms to Review (21)
Bayesian reasoning: Bayesian reasoning is a statistical method that involves updating the probability of a hypothesis as more evidence or information becomes available. It uses Bayes' theorem to calculate the likelihood of an event based on prior knowledge and new data, allowing for a coherent integration of beliefs and evidence over time.
Belief Evaluation: Belief evaluation is the process of assessing the justification and coherence of one's beliefs within a network of interconnected ideas. This process is central to coherentism, where beliefs gain their validity not in isolation but through their relationships and harmony with other beliefs. It emphasizes how beliefs can either support or undermine each other, highlighting the importance of a consistent web of beliefs in achieving a justified belief system.
Belief Revision: Belief revision refers to the process of changing one's beliefs when presented with new evidence or information that conflicts with previously held beliefs. This concept emphasizes how individuals or systems update their beliefs in response to contradictions, thereby maintaining a coherent set of beliefs. The process is critical in understanding how knowledge is constructed and adjusted over time, particularly when engaging with different perspectives or challenging situations.
Circular Justification: Circular justification refers to a situation in which a belief is supported by another belief in a way that ultimately relies on the original belief, creating a loop of reasoning that fails to provide independent support. This concept is significant within coherentism, which posits that beliefs are justified through their coherence with other beliefs in a web, rather than through external evidence or foundational beliefs. The challenge with circular justification is that it can undermine the validity of a belief system if it relies solely on itself for validation.
Coherence Maximization: Coherence maximization is the principle that suggests beliefs should be organized and structured in a way that enhances their mutual support and consistency with one another. This concept plays a crucial role in coherentism, which posits that the justification of beliefs arises not from their correspondence to external reality but from their coherence within a web of interconnected beliefs. The aim of coherence maximization is to create a robust and harmonious system of beliefs where each belief strengthens the overall framework.
Coherence Theories: Coherence theories are a set of beliefs about how we justify knowledge claims, emphasizing the interconnections and consistency among a web of beliefs. In this view, a belief is justified if it coherently fits with other beliefs within a system, rather than being grounded in direct sensory experience or empirical evidence. This perspective shifts the focus from isolated beliefs to the overall structure of belief systems and their mutual support.
Coherentism: Coherentism is a theory of justification in epistemology that holds that beliefs are justified if they cohere or fit well together within a system of interconnected beliefs. This perspective contrasts with foundationalism, which asserts that some beliefs are justified independently of others. Coherentism emphasizes the holistic nature of justification, suggesting that beliefs gain their justification from their relationships to other beliefs in a cohesive web.
Entrenchment of beliefs: Entrenchment of beliefs refers to the process by which certain beliefs become deeply rooted and resistant to change within an individual's web of understanding. This occurs as beliefs interact with and reinforce each other, creating a cohesive structure that supports the overall framework of one's knowledge. The more integrated and interconnected these beliefs become, the more difficult it is for individuals to challenge or revise them, even in the face of contradictory evidence.
Epistemic Circularity: Epistemic circularity refers to a situation where the justification for a belief relies on the belief itself, creating a loop that can undermine the reliability of that justification. This concept highlights how certain systems of belief, especially coherentist approaches, can lead to challenges in validating knowledge claims since they depend on their own internal consistency rather than external verification.
Explanatory Coherence: Explanatory coherence refers to the quality of a set of beliefs or propositions that logically fit together to provide a consistent and plausible account of phenomena. This concept is crucial for evaluating how well our beliefs align with one another and with the evidence, as coherent beliefs support each other and form a web that helps explain our understanding of the world.
External Consistency: External consistency refers to the alignment of a belief system with the external world or empirical evidence outside of one's web of beliefs. It emphasizes that beliefs should not only cohere with one another but also fit with facts and observations from the real world, allowing for a more comprehensive understanding of truth.
Foundationalism: Foundationalism is a theory in epistemology that posits certain basic beliefs serve as the foundational bedrock for all other beliefs and knowledge claims. These basic beliefs are considered self-evident or infallible, providing a secure starting point for building a more comprehensive system of knowledge. This approach aims to solve issues like skepticism by establishing a firm base from which further justified beliefs can be derived.
Holistic Justification: Holistic justification is the idea that a belief is justified not in isolation but as part of a larger system of interconnected beliefs. This concept emphasizes that the coherence and mutual support among a web of beliefs play a crucial role in determining the justification of individual beliefs within that network. In this view, beliefs gain strength and credibility from their relationships with other beliefs rather than standing alone.
Inferential relationships: Inferential relationships refer to the connections and logical links that exist between beliefs, where one belief supports or leads to another. This concept is crucial for understanding how beliefs can be justified within a coherent system, as it emphasizes that beliefs are not isolated but rather interdependent. By examining these relationships, one can assess the overall coherence of a set of beliefs, highlighting how they work together to form a unified worldview.
Internal Consistency: Internal consistency refers to the coherence and logical harmony within a set of beliefs or propositions. This concept is crucial for evaluating a belief system, ensuring that various beliefs support and do not contradict each other. In the context of coherentism, internal consistency is essential, as it promotes a web of interconnected beliefs where each belief reinforces others, creating a stable and unified framework of understanding.
Minimal Mutilation Principle: The minimal mutilation principle is a concept in epistemology that suggests that when revising or rejecting beliefs, one should only discard or modify the least amount of those beliefs necessary to maintain coherence within a system of beliefs. This principle promotes the idea of preserving as many beliefs as possible while ensuring that the remaining beliefs remain logically interconnected, supporting the coherentist view of knowledge.
Mutual Support: Mutual support refers to the idea that beliefs within a system bolster each other, creating a cohesive web of interconnected beliefs. In this framework, the justification for any individual belief is not isolated; rather, it relies on its relationships with other beliefs, leading to a system where support flows in multiple directions and strengthens the overall coherence.
Probabilistic Approaches: Probabilistic approaches refer to methods of reasoning and belief formation that emphasize the role of probability in evaluating the justification of beliefs. These approaches suggest that beliefs can be justified to varying degrees based on the likelihood of their truth, integrating elements of uncertainty and evidence into the web of interconnected beliefs. This perspective aligns closely with coherentism, where the justification of a belief depends not only on its individual support but also on how well it fits within a broader network of beliefs.
Regress Problem: The regress problem is a challenge in epistemology that questions how beliefs can be justified. It addresses the concern that for any belief to be justified, it must be supported by another belief, which in turn requires further justification, leading to an infinite chain of justifications or a circular reasoning scenario. This creates a dilemma for theories of knowledge, as it raises issues regarding how we can arrive at justified beliefs without getting stuck in an endless regress or falling into circularity.
Truth-seeking: Truth-seeking refers to the pursuit of knowledge and understanding through critical inquiry, rational analysis, and the evaluation of evidence. It emphasizes the importance of finding accurate and reliable information to form beliefs that align with reality. This pursuit often involves connecting and integrating various pieces of information within a coherent framework and relies on the intellectual virtues of individuals who engage in this process.
Web of beliefs: The web of beliefs is a metaphorical concept used in epistemology to describe how individual beliefs are interconnected and supported by one another, forming a complex structure. This concept highlights the idea that beliefs are not isolated but rather influence and rely on each other, creating a coherent system of knowledge. In this framework, the justification of any single belief often depends on its relationship with other beliefs within the web.
