W.V.O. Quine’s 1951 essay Two Dogmas of Empiricism is one of the most influential critiques of logical positivism and the broader empiricist tradition. It calls into question two central tenets or “dogmas” of empiricism: the analytic-synthetic distinction and reductionism. By dissecting these dogmas, Quine sets the stage for a more holistic and naturalized view of knowledge, radically departing from the received tradition of analytic philosophy.
The Analytic-Synthetic Distinction
The analytic-synthetic distinction is a central concept in modern philosophy, originating from Immanuel Kant and developed by logical positivists. The distinction separates analytic truths, which are true by virtue of meanings alone, from synthetic truths, which are true by virtue of empirical facts.
Quine’s Critique of the Analytic-Synthetic Distinction
Quine argues that this distinction is fundamentally flawed. The critique unfolds in a sequence of logical steps:
- Definitions of Analyticity are Vague: Quine begins by challenging the traditional definitions of analytic statements as “true by virtue of meanings alone” or “true by definition.” According to Quine, these definitions are inherently circular because they rely on the notion of synonymy, which itself presupposes the very idea of analyticity. Therefore, any attempt to define analytic truths in non-circular terms fails.
- Rejection of Synonymy: Quine next tackles the concept of synonymy, or sameness of meaning. He argues that there is no satisfactory way to determine when two terms are synonymous without invoking a notion of analyticity, thus leading to a vicious circle. Without a clear account of synonymy, the idea of analyticity falls apart. For Quine, meaning is not something we can isolate and analyze independently from the broader web of beliefs and experiences.
- Verificationist Theories and Failure: Quine also takes aim at verificationism, the principle that a statement’s meaning is tied to the method of verifying it. According to logical positivists, analytic statements are those that can be verified independently of empirical observation. However, Quine argues that verificationism fails to distinguish between analytic and synthetic truths in a non-circular way, further undermining the analytic-synthetic distinction.
Important Concept: Quine’s holistic view of meaning challenges the idea that individual statements can be understood in isolation. Instead, meaning arises from the interconnected web of all our beliefs.
- No Sharp Line between Analytic and Synthetic: Quine concludes that the analytic-synthetic distinction collapses upon closer inspection. Rather than existing as separate categories, all statements about the world, whether traditionally considered analytic or synthetic, are part of a continuum. This insight leads to Quine’s holistic view of knowledge, where no statement is immune to revision, including those once considered analytic.
Implications of the Collapse of the Analytic-Synthetic Distinction
- Undermining of Logical Positivism: The failure of the analytic-synthetic distinction is a blow to logical positivism, a movement that relied heavily on this distinction to separate empirical and logical truths.
- Reconstruction of Meaning: Quine’s attack on the distinction forces a rethinking of how we understand meaning in language. Meaning can no longer be viewed as isolated within individual sentences but must be seen as embedded in the whole of language and experience.
- Scientific Theories as Revisable: Since no statements are immune to revision, Quine suggests that even fundamental laws of logic and mathematics may, in principle, be revised in light of empirical evidence. This radical suggestion moves philosophy closer to scientific practice, where all hypotheses are subject to revision.
Quine’s Critique of Reductionism
The second “dogma” Quine critiques is reductionism, the idea that every meaningful statement can be reduced to a set of observations or sense data. This notion was central to empiricism, which held that all knowledge must be grounded in immediate experience.
Quine’s Rejection of Reductionism
Quine’s critique of reductionism proceeds through several key arguments:
- Rejection of a Statement-to-Experience Relationship: According to Quine, there is no simple one-to-one correspondence between individual statements and particular sense experiences. Instead, statements about the world are interconnected, and their verification depends not just on individual observations but on the entire system of beliefs we hold.
- Confirmation Holism: Quine introduces the idea of confirmation holism, the view that individual statements cannot be tested or confirmed in isolation. Instead, what we test when we make an observation is a whole network of beliefs. For example, testing a scientific theory involves testing many assumptions at once, not just individual statements about particular phenomena.
Important Concept: Confirmation holism emphasizes that changes in one part of our system of knowledge may require adjustments elsewhere in the system. This view fundamentally challenges the empiricist idea that we can directly tie individual statements to specific observations.
- Underdetermination of Theory by Evidence: Quine also points out that empirical evidence alone cannot determine which theory is correct because multiple, equally consistent theories can explain the same observations. This concept, known as the underdetermination of theory by evidence, challenges the empiricist idea that we can arrive at a unique, correct description of the world purely through observation.
- Language and Observation are Interdependent: Finally, Quine argues that our language and conceptual framework shape our observations, meaning that sense data cannot serve as a neutral foundation for knowledge. Instead, what we observe depends on how we interpret the world through our language and theories.
Quine’s Holism and Naturalized Epistemology
Quine’s rejection of the two dogmas leads him to a holistic view of knowledge and a new approach to epistemology.
Quine’s Holistic Epistemology
- Knowledge as a Web of Beliefs: Quine famously likens human knowledge to a web of beliefs, with some statements at the periphery more easily revised in light of new evidence and others at the center, such as logical or mathematical truths, which are more resistant to change. However, no statement is beyond revision.
- Naturalized Epistemology: Quine advocates for a naturalized epistemology, which rejects the traditional philosophical project of seeking a justification for knowledge outside of the natural sciences. Instead, Quine proposes that epistemology should become a part of the natural sciences, studying how humans actually form beliefs and acquire knowledge based on empirical methods.
Process Flow: empirical observation → conceptual frameworks → revisions in the web of beliefs
- Fallibility of All Knowledge: In Quine’s system, even the most basic elements of our conceptual framework—such as logic and mathematics—are subject to revision, should empirical evidence demand it. This approach marks a significant break from traditional philosophy, which often sought to establish certain, foundational truths.

Conclusion
Quine’s Two Dogmas of Empiricism is a landmark in the development of contemporary philosophy. By dismantling the analytic-synthetic distinction and reductionism, Quine challenges fundamental assumptions of empiricism and opens the door to a more holistic, naturalized understanding of knowledge. This shift marks a profound departure from traditional approaches, situating philosophy more closely with scientific practice.
