9.3 Quine: Naturalized Epistemology
3 min read•august 15, 2024
Quine shook up philosophy by challenging the divide between analytic and synthetic statements. He argued all knowledge is connected and can be revised based on new evidence. This view undermined traditional ideas about a priori knowledge and logical positivism.
Quine's proposed studying knowledge as a branch of science, not just philosophy. This blurred lines between disciplines and suggested philosophical questions could be tackled with scientific methods. His ideas greatly influenced modern philosophical approaches.

1 of 3
- Quine challenged the traditional distinction between analytic and synthetic statements
- Analytic statements previously considered true by definition
- Synthetic statements previously considered true based on empirical evidence
- Argued this distinction is not as clear-cut as previously thought
- Even seemingly analytic statements rely on empirical assumptions
- All statements can be revised in light of new evidence
- of words and concepts determined by use within broader network of beliefs and theories
- Holistic nature of knowledge suggests no statement immune to revision based on empirical evidence
Implications for Philosophy
- Undermines notion of a priori knowledge
- Challenges foundation of logical positivism and traditional epistemology
- Rejection of impacts:
- Nature of philosophical analysis
- Relationship between language, meaning, and truth
- Examples of challenged analytic statements:
- "All bachelors are unmarried" (relies on cultural assumptions about marriage)
- "2 + 2 = 4" (based on empirical experiences with counting objects)
Naturalized Epistemology and Science
Reframing Epistemology
- Proposes study of knowledge as branch of empirical science rather than purely philosophical endeavor
- Argues traditional epistemology's goal of providing foundation for scientific knowledge misguided
- Replaces traditional approach with scientific study of human knowledge acquisition

Ontological Relativity and Reality
Conceptual Frameworks and Existence
- Posits objects and structures perceived in world relative to conceptual schemes and linguistic frameworks
- Argues no absolute, observer-independent way to determine what exists
- Ontological commitments always relative to particular theory or language
- Introduces idea of inscrutability of
- Reference of terms in language cannot be determined absolutely

- Supports form of
- Choice between competing ontologies based on explanatory power and practical utility
- Not based on absolute truth
- Examples of ontological relativity:

- Philosophy of language
- Metaphysics
- Both influential and controversial
- Sparked ongoing debates about proper methods and scope of philosophical inquiry
- Examples of Quine's influence:
- Naturalized approaches to ethics (evolutionary psychology informing moral philosophy)
- Cognitive science of religion challenging traditional philosophical arguments for existence of God
Key Terms to Review (18)
Analytic-synthetic distinction: The analytic-synthetic distinction is a philosophical concept that differentiates between two types of statements: analytic statements, which are true by virtue of their meanings and logical structure, and synthetic statements, which require empirical evidence for their truth. This distinction is significant in discussions of knowledge, language, and meaning, especially as it relates to the nature of truth and justification in epistemology.
Behaviorism: Behaviorism is a psychological approach that emphasizes the study of observable behaviors rather than internal mental processes. It posits that all behaviors are acquired through conditioning, which can be observed and measured, making it a scientific approach to understanding human and animal behavior. This perspective connects to naturalized epistemology by suggesting that knowledge can be derived from empirical observations of behavior.
David Hume: David Hume was an 18th-century Scottish philosopher known for his influential ideas on empiricism, skepticism, and naturalism. He is best recognized for challenging the notions of causality and the existence of innate ideas, which connects deeply with other philosophical discussions surrounding idealism, the nature of knowledge, and epistemological approaches in modern thought.
Empirical Knowledge: Empirical knowledge refers to knowledge gained through experience, observation, and experimentation, rather than through intuition or pure reason. It is foundational in the scientific method, emphasizing that all ideas should be tested against reality to be considered valid. This concept interacts with various philosophical theories regarding the limits of human understanding and how we acquire knowledge about the world.
Epistemological continuity: Epistemological continuity refers to the idea that there is a seamless relationship between different forms of knowledge and understanding, particularly in how scientific inquiry relates to philosophical investigation. This concept suggests that epistemology should be rooted in empirical science rather than being a separate domain, emphasizing the ongoing dialogue between our scientific theories and our broader philosophical assumptions.
Falsifiability: Falsifiability is the principle that a hypothesis or theory must be able to be proven false through observation or experimentation. This idea plays a crucial role in distinguishing scientific claims from non-scientific ones, as it emphasizes that for a theory to be considered scientific, it must make predictions that can potentially be tested and shown to be incorrect.
Holism: Holism is the philosophical perspective that systems and their properties should be viewed as wholes, rather than as collections of parts. This approach emphasizes that the interactions and relationships between components are crucial for understanding the nature and behavior of the entire system. In epistemology, particularly in the context of naturalized epistemology, holism underscores the idea that knowledge cannot be fully understood by examining isolated beliefs or propositions in isolation, but rather by considering the network of beliefs and their interconnections.
Meaning: Meaning refers to the significance or interpretation of words, symbols, or expressions within a given context. It plays a crucial role in how communication is understood and conveys the intention behind utterances, contributing to both linguistic and philosophical discussions. In different philosophical frameworks, the concept of meaning can shift from being a mere representational function of language to a more pragmatic understanding that involves the context and use of language in social interactions.
Naturalized epistemology: Naturalized epistemology is a philosophical approach that seeks to understand knowledge and justified belief through the lens of empirical science, particularly psychology and cognitive science. It challenges traditional epistemological views by arguing that epistemological questions should be addressed with methods and concepts from the sciences, thereby integrating human cognition with the study of knowledge. This perspective shifts the focus from abstract theorizing about knowledge to understanding how humans actually acquire and validate their beliefs.
Observation sentences: Observation sentences are statements that describe empirical observations, often used in the context of scientific discourse and epistemology to establish a foundation for knowledge claims. These sentences are meant to be directly verifiable through sensory experience and serve as a bridge between theory and observation, emphasizing the role of experience in understanding truth.
Pragmatism: Pragmatism is a philosophical approach that assesses the truth of beliefs and theories based on their practical consequences and applications. It emphasizes that the meaning of concepts is rooted in their observable effects and usefulness, allowing for a dynamic understanding of knowledge and reality that adapts to changing circumstances.
Quine's Indeterminacy of Translation: Quine's indeterminacy of translation is the philosophical idea that there is no unique correct translation between different languages, as the meaning of words and sentences cannot be precisely determined without considering the entirety of a speaker's linguistic behavior and the context in which they operate. This concept suggests that multiple translations can be equally valid, challenging traditional views on language, meaning, and understanding.
Reference: Reference is the relationship between a term and the object or concept it denotes or stands for. It plays a crucial role in communication and understanding, as it helps clarify what we mean when we use certain words or phrases. In different philosophical contexts, like analyzing knowledge and meaning, reference is vital in exploring how language relates to the world and how statements can convey information about it.
Scientific realism: Scientific realism is the philosophical position asserting that the world described by science is real, regardless of whether it is observable or not. This view holds that scientific theories accurately depict the nature of the universe and its entities, implying that unobservable phenomena posited by science are as real as observable ones. This perspective contrasts with anti-realism, emphasizing the belief that the success of scientific theories is best understood through their truthfulness about the world.
The problem of the external world: The problem of the external world refers to the philosophical challenge of justifying our beliefs about the existence and nature of the world outside of our own minds. This issue raises questions about how we can know that our perceptions accurately reflect reality, considering that our sensory experiences can be deceptive or limited. It is particularly relevant in discussions of skepticism, where doubt is cast on our ability to gain true knowledge of the world beyond our thoughts and perceptions.
The web of belief: The web of belief is a metaphor used to describe how individual beliefs are interconnected and form a complex network, suggesting that beliefs are not isolated but rather depend on and support one another. This concept highlights the idea that our understanding of the world is shaped by a system of beliefs where some beliefs hold more weight than others, leading to the notion that changes in one part of the web can affect the entire structure.
Theory-ladenness of observation: The theory-ladenness of observation is the idea that what we observe and how we interpret those observations are influenced by our existing theories, beliefs, and concepts. This means that observations are not purely objective; rather, they are shaped by the theoretical frameworks we already have in place, affecting our understanding and interpretation of the data we gather.
Willard Van Orman Quine: Willard Van Orman Quine was an influential American philosopher and logician in the 20th century, known for his work in epistemology, philosophy of language, and logic. He is particularly recognized for his proposal of naturalized epistemology, which integrates scientific methods into the study of knowledge, challenging traditional views that separate philosophy from empirical science.
