Farewell to Reason

The central argument is that 'Reason'—capitalized, singular, and universal—is not a neutral standard but a particular intellectual tradition that has been used to delegitimise others. Feyerabend argues that what is called 'reason' is a specific set of procedures and values that emerged in Western philosophy and science, and that its authority rests on power rather than on a neutral, universal validity. The book's distinctive mechanism is historical and anthropological: Feyerabend shows that cultures dismissed as irrational possess their own coherence and forms of life, and that the imposition of Western rationality has been an act of cultural conquest, not intellectual progress. The title is a deliberate provocation: to bid farewell to Reason is to abandon the illusion that there is a single standard to which all traditions must submit.

Farewell to Reason extends the argument of Against Method (1975) from the philosophy of science into the broader cultural and political domain. Against Method argued that there is no universal scientific method and that scientific progress has depended on violating methodological rules. Farewell to Reason generalises this critique: 'reason' itself, not just scientific method, is a particular tradition rather than a universal standard. The continuity is in the pluralism: Feyerabend's target is always the claim that a single set of standards applies to all inquiry and all cultures. The difference is in scope: the later book is more explicitly political and cultural, engaging with issues of colonialism, education, and the authority of experts. It is not a change of position but a broadening of the critique.

Feyerabend's pluralism is the view that diverse traditions and forms of life should coexist and be granted equal standing, rather than being subordinated to a single universal standard. He argues that the proliferation of theories and ways of life is beneficial for knowledge and for human flourishing. But pluralism, as Feyerabend understands it, is not the same as relativism. Relativism is the view that all beliefs are equally true, or that truth is relative to a framework. Feyerabend does not assert this; he argues that no single framework has the authority to judge all others, and that the choice between traditions is a matter of practical and political negotiation, not of abstract rational assessment. The distinction matters because critics often accuse him of relativism, while he insists that his position is a defence of diversity, not an abdication of judgment.

Reception was divided along familiar lines. Sympathetic reviewers saw it as a powerful and necessary critique of the pretensions of Western rationality, while hostile critics accused Feyerabend of relativism, irrationalism, and intellectual irresponsibility. The most common criticism was that his pluralism undermines the possibility of rational criticism and leaves no basis for distinguishing between better and worse traditions. Some critics also noted that his historical and anthropological examples were selective and sometimes inaccurate. Feyerabend's defenders responded that the book is a provocation designed to challenge complacent assumptions about the superiority of Western reason, not a systematic treatise. The book has been influential in debates about multiculturalism, science and society, and the politics of knowledge.

The two books are closely related. Science in a Free Society (1978) argued that science should be separated from the state and treated as one tradition among many in a democratic society. Farewell to Reason (1987) generalises this argument: it is not just science that has been granted a privileged position, but 'reason' itself—the set of standards that science claims to embody. The later book extends the political critique of expertise into a broader cultural critique of Western rationality. Both books share the same pluralist vision: a society in which diverse traditions coexist on equal terms, without any single tradition claiming universal authority. Farewell to Reason is thus the culmination of the political and cultural argument that Feyerabend began in Science in a Free Society.

The most common misunderstanding is that Feyerabend is advocating the abandonment of reason altogether—that he is an irrationalist who believes anything goes. In fact, he is not rejecting reason; he is rejecting the dogmatic claim that a particular conception of reason is universally valid and should be imposed on all cultures and traditions. He is arguing for a more modest, pluralistic understanding of rationality, one that recognizes the diversity of human forms of life. A related misunderstanding is that he is a relativist who believes all beliefs are equally true. He does not claim this; he claims that no single framework has the authority to judge all others, and that the choice between traditions is a practical and political matter. Reading the book as a defence of chaos misses its serious philosophical and political argument.
