Galileo's early telescopic observations could not be fully justified using the optical theory of his day, and his heliocentric arguments initially performed worse than Ptolemaic models on some observational tests. According to Feyerabend, this episode illustrates that:
AGalileo succeeded despite violating the rules of good science, showing that individual genius can overcome methodological failures
BScientific progress sometimes requires developing and defending theories that currently violate accepted methodological rules
CThe methodological rules of 16th-century science were simply wrong, and better rules would have endorsed heliocentrism immediately
DHistorical evidence is insufficient to evaluate scientific theories, so methodology is irrelevant
Feyerabend's point is not that Galileo was unusually gifted or that the rules were merely defective. His argument is that the rules themselves — 'only accept theories better supported by current evidence' — would have killed heliocentrism before it could develop. Progress required temporarily tolerating a theory that was, by contemporary standards, empirically weaker. Option A attributes success to individual genius rather than the structural argument about methodology. Option C misses Feyerabend's claim: he's not saying we just need better rules, but that any fixed rules will eventually obstruct progress.
Question 2 Multiple Choice
What is the primary target of Feyerabend's slogan 'anything goes'?
AThe claim that scientific theories are more reliable than non-scientific ones
BThe idea that there exists a universal, rule-based scientific method that scientists follow and should follow
CThe practice of peer review and institutional gatekeeping in science
DThe Popperian requirement that theories must make falsifiable predictions
Feyerabend's target is the philosophy that science has — or should have — a single canonical method (inductive confirmation, falsificationism, Lakatosian progressiveness). His historical argument is that no such method actually describes how successful science has proceeded, and his prescriptive claim is that enforcing such a method would harm science. Option D is too narrow — Popper is one target but not the exclusive one. Option C is a consequence Feyerabend draws, not the primary target.
Question 3 True / False
Feyerabend's claim that 'anything goes' is equivalent to saying that astrology and modern physics are equally valid or equally true theories.
TTrue
FFalse
Answer: False
'Anything goes' is an epistemological claim about methodology, not a metaphysical claim about which theories are true. Feyerabend explicitly argues that insisting on a single method has costs — it suppresses competing frameworks that could reveal limitations of the dominant paradigm. He is not claiming all theories are equally good. His defense of alternative traditions (astrology, traditional medicine) is not an endorsement of their truth claims but a criticism of institutional gatekeeping that might filter out genuine insights. Confusing epistemological anarchism with relativism is the most common misreading of Feyerabend.
Question 4 True / False
Feyerabend's historical analysis implies that strict adherence to the methodological rules dominant at a given time could have prevented major episodes of scientific progress.
TTrue
FFalse
Answer: True
This is central to Feyerabend's argument. Using the Galileo case and others, he shows that scientists who made major advances did so by violating — not following — the established methodological standards of their era. Counter-induction (developing theories that contradict well-confirmed evidence) is not a pathology to be eliminated but a historical engine of progress. The prescription 'follow the best current method' would have been self-defeating in precisely those moments when science needed to break out of its current framework.
Question 5 Short Answer
What is 'counter-induction' in Feyerabend's framework, and why does he claim it is sometimes scientifically valuable rather than irrational?
Think about your answer, then reveal below.
Model answer: Counter-induction is the practice of developing theories that contradict well-established evidence or currently dominant theories, rather than waiting for a theory to be empirically well-supported before pursuing it. Feyerabend argues this is valuable because maintaining competing frameworks — even ones currently inferior by standard metrics — reveals anomalies and limitations in the dominant paradigm that would be invisible from within. Like a marketplace of ideas, genuine competition surfaces information that a monopoly suppresses.
The analogy to market competition is illuminating: if only one product is allowed, you never discover its weaknesses. Feyerabend applies this to theory competition — allowing 'underperforming' theories to persist and develop gives them the chance to grow into the next paradigm shift. This is prescriptive pluralism, not relativism: the goal is better science through more competition, not the abandonment of scientific evaluation altogether.
