Book: The Collapse of the Fact/Value Dichotomy

Overview

Hilary Putnam challenges a long-standing separation between facts and values, arguing that the boundary is neither sharp nor defensible. He examines historical sources of the dichotomy, critiques philosophical moves that sustain it, and offers a pragmatic alternative that treats values as intertwined with cognition, language, and inquiry. The volume gathers essays that range across metaphysics, epistemology, ethics, and the philosophy of science to show how normative considerations permeate what counts as knowledge and truth.

Main Thesis

Putnam contends that the fact/value dichotomy collapses once one recognizes that conceptual frameworks, descriptive practices, and standards of justification are suffused with evaluative commitments. Facts do not present themselves in a value-neutral vacuum; choices about how to describe, classify, and investigate phenomena inevitably reflect aims, interests, and norms. Far from endorsing relativism, Putnam maintains that acknowledging the entanglement of facts and values can secure a robust form of objectivity that remains responsive to human purposes.

Arguments Against the Dichotomy

Putnam traces the dichotomy to influential figures and philosophical traditions that insisted on a strict separation: Hume's famous is/ought distinction, logical positivist accounts that confined value claims to emotive or noncognitive status, and certain readings of analytic philosophy that treated semantics and normativity as separable. He argues these moves rest on simplistic models of language and mind. By examining cases from science and ordinary discourse, Putnam shows that what counts as evidence, the formulation of hypotheses, and the acceptance of theories depend on value-laden criteria such as simplicity, relevance, and practical utility.

Philosophical Resources and Method

A pragmatist sensibility underpins Putnam's method: concepts are tools for coping with the world, and their usefulness is judged by standards that include moral and epistemic values. He draws on themes from his earlier philosophy, semantic externalism, the critique of metaphysical realism, and internalist accounts of rationality, while distancing himself from reductionist naturalism. Putnam emphasizes reflective equilibrium and the interplay between normative reflection and empirical inquiry, proposing that justification is a social, historically situated activity guided by both descriptive and evaluative considerations.

Implications for Ethics, Science, and Law

Accepting the collapse of the fact/value divide reshapes how one thinks about ethical inquiry, the aims of science, and the role of law. Ethical judgments are not merely expressions of sentiment but can be assessed by criteria that make them subject to rational discussion and revision. Scientific practice, once seen as purely objective, is revealed to involve value judgments in choice of methods, research priorities, and interpretation of data. Legal reasoning likewise shows an interplay between descriptive facts and normative principles, so that jurisprudence must attend to both empirical realities and value-laden concepts.

Legacy and Significance

Putnam's intervention challenges philosophers to reconceive objectivity and realism without reverting to a sterile fact/value bifurcation. By insisting that values can be rationally engaged and integrated into theory choice, he offers an alternative to both relativism and a deflationary view of normativity. The essays sparked debate across analytic philosophy, philosophy of science, and ethics, prompting renewed attention to how conceptual frameworks mediate the relation between facts and values and encouraging more pluralistic, practice-sensitive accounts of justification and truth.
