Q & A
What is the main disagreement between Kuhn and Popper regarding science?
-The main disagreement concerns Kuhn's concept of 'normal science.' Kuhn believes that most scientists engage in research dictated by a paradigm, while Popper argues that this is not science, as real scientific problem-solving involves creativity and imagination rather than puzzle-solving within a fixed framework.
How does Kuhn define 'normal science'?
-Kuhn defines 'normal science' as the research that scientists conduct once a paradigm is accepted. This research is driven by the rules and expectations of the paradigm, focusing on solving puzzles within that established framework.
What is Popper’s critique of Kuhn’s concept of normal science?
-Popper critiques Kuhn’s concept by stating that normal science, as Kuhn describes it, is not true science. For Popper, science is a creative, imaginative activity that constantly seeks to refute existing solutions, rather than merely solving puzzles within the confines of a paradigm.
How do Kuhn and Popper differ in their views on scientific observations?
-Kuhn argues that scientific observations are always made through the lens of a paradigm, meaning that psychological and sociological factors influence how scientists perceive reality. Popper, on the other hand, believes that science is objective, and observations should aim to pass rigorous refutation without being influenced by such factors.
What is Popper’s stance on the truth in science?
-Popper accepts the correspondence theory of truth, which means he believes there are objective truths about the physical world that science can approximate.
What is Kuhn’s view on the concept of truth in science?
-Kuhn rejects the correspondence theory of truth and believes that the truth is relative to the paradigm accepted by scientists at a given time. In his view, different paradigms create different realities for scientists to explore.
How does Paul Feyerabend's view of science differ from Kuhn’s and Popper’s?
-Feyerabend adopts an anarchistic view of science, arguing that there are no fixed methods or rules in scientific practice. He believes that successful scientific progress often breaks the conventional rules, and any method that advances knowledge should be accepted.
What does Paul Feyerabend mean by 'anarchism' in science?
-Feyerabend’s 'anarchism' in science refers to the idea that there is no single scientific method or prescribed set of rules. Scientific progress is achieved through creativity and opportunism, and sometimes breaking established rules is necessary for advancement.
How does Feyerabend describe successful scientific research?
-Feyerabend describes successful scientific research as a process that does not adhere to general standards or rules. Instead, it relies on different methods and tricks depending on the situation, and progress is made through a flexible, unrestricted inquiry.
What remains constant in science despite the different views of Kuhn, Popper, and Feyerabend?
-Despite their differences, empirical observation remains the ultimate authority in science, lawful relationships are still sought, theories are still formulated and tested, and determinism is generally assumed as a guiding principle in scientific research.
Outlines
🎬 Introduction to Kuhn and Popper's Scientific Theories
The video introduces the concepts of science by Kuhn and Popper, emphasizing their differences and similarities. It encourages viewers to explore related videos on the channel for an in-depth understanding. The key focus is the contrast between Kuhn’s idea of 'normal science' and Popper’s belief that scientific problems require creativity and are not constrained by paradigms.
🔬 Kuhn's Concept of Normal Science vs. Popper's Problem-Solving
Kuhn argues that once a paradigm is accepted, scientists engage in research dictated by that paradigm, which he calls 'normal science.' In contrast, Popper denies that normal science is true science, as scientific problems are more imaginative and creative than merely solving puzzles within a set framework. Popper stresses that science involves open-ended problem-solving, without predefined solutions.
🧠 The Role of Paradigms in Observation
Kuhn emphasizes that scientific observations are influenced by the accepted paradigm, rejecting the idea of neutral observation. For Kuhn, paradigms shape how scientists view reality. In contrast, Popper focuses on the rigorous testing of solutions, where problems either survive attempts to refute them or they don't. The key divergence is Kuhn's emphasis on convention and subjectivity versus Popper's focus on creativity and logic.
🤝 Bridging Kuhn and Popper’s Views
The video presents a reconciliatory view, suggesting that the disagreements between Kuhn and Popper might dissolve if Kuhn is seen as describing what science has been, and Popper as prescribing what it should be. However, it is clear that Popper believed in an objective truth that science could approximate, while Kuhn thought that truth was relative to the paradigm in use.
⚖️ Kuhn's Paradigm-Dependent Truth vs. Popper's Objective Truth
The basic difference between Kuhn and Popper is highlighted: Popper believes science can approximate the physical world's truths, supporting the correspondence theory of truth. On the other hand, Kuhn rejects this idea, arguing that scientists' paradigms shape the reality they explore, making truth relative to these paradigms.
🧑🔬 Diverse Philosophies of Science: Creativity vs. Method
The video explores the view of some philosophers who argue that characterizing science is misleading since there is no one scientific method. Percy W. Bridgman is mentioned, stating that science is defined by what scientists do, with as many methods as there are scientists. The focus is on the individuality and creativity of researchers.
📚 Paul Feyerabend’s Anarchistic Theory of Science
Paul Feyerabend's theory is introduced, where he aligns with philosophers who claim that scientists follow no fixed rules. He argues that breaking existing rules is often necessary for scientific progress. Feyerabend’s thesis is that an anarchistic approach, allowing occasional rule-breaking, is essential for achieving scientific advancements.
🚫 Anything Goes: Science Without Boundaries
Feyerabend continues his anarchistic view, claiming that science should have no single method and that opportunism drives progress. Successful research, according to him, relies on flexibility, using various approaches depending on the problem at hand, and not adhering strictly to established scientific standards.
🔄 Traditional Science Methods: Still Relevant
Despite the revisions suggested by Kuhn, Popper, and Feyerabend, traditional aspects of science remain intact. Empirical observation is still seen as the ultimate authority, theories are formulated and tested, lawful relationships are sought, and determinism is assumed. These remain core elements of scientific practice.
👍 Conclusion and Call to Action
The video ends with a reminder for viewers to like, share, comment, and subscribe to the channel. It summarizes the discussion on the philosophical differences between Kuhn, Popper, and Feyerabend, emphasizing their views on scientific methodology and progress.

Highlights
Popper's major disagreement with Kuhn revolves around Kuhn's concept of normal science, which Popper argues is not science at all.
Kuhn suggests that once a paradigm is accepted, most scientists engage in 'normal science,' which is essentially research within the framework of the paradigm.
Popper claims that scientific problem-solving is a highly imaginative and creative process, not merely puzzle-solving as Kuhn describes.
Kuhn emphasizes that science cannot be understood without considering psychological and sociological factors, arguing that observations are made through the lens of a paradigm.
Popper contrasts Kuhn by asserting that scientific problems exist independently of paradigms, and proposed solutions must pass rigorous attempts at refutation.
Kuhn's analysis of science stresses conventions and subjective factors, while Popper's analysis emphasizes logic and creativity.
A conciliatory view suggests that Kuhn may describe what science has been historically, while Popper describes what it ought to be.
Popper accepted the correspondence theory of truth, believing that science can approximate truths about the physical world.
Kuhn rejected the correspondence theory, suggesting that a scientific paradigm creates the reality that scientists explore.
Kuhn's radical view suggests that truth is relative to the paradigm accepted by scientists at a given time.
Paul Feyerabend, in his anarchistic theory of knowledge, argued that no single scientific method exists and that breaking rules is necessary for scientific progress.
Feyerabend believed that science progresses when anarchistic moves are allowed, as no single set of rules can account for past or future advancements.
In practice, science oversteps boundaries, and successful research often relies on opportunism and flexibility rather than following strict rules.
Feyerabend asserted that theories of science that impose rigid standards might impress outsiders but are too simplistic for scientists dealing with real research problems.
Despite revisions by Popper, Kuhn, and Feyerabend, many traditional aspects of science remain, such as the importance of empirical observation and the pursuit of lawful relationships between phenomena.

hello welcome to learning studio
this video is about
and popper's concept of science
comparatively which will make you
understand the differences and
similarities about their views if you
want to know about the full views of
kuhn and popper about science
watch the videos on our channel link is
available in the description box down
below let's start this video a major
source of disagreement between kuhn and
popper concerns kuhn's concept of normal
science as we have seen kuhn says that
once a paradigm has been accepted
most scientists busy themselves with
research projects dictated by the
paradigm
that is doing normal science for popper
what kuhn called normal science is not
science at all scientific problems are
not like puzzles because there are no
restrictions either on what counts as a
solution or on what procedures can be
followed in solving a problem according
to popper
scientific problem solving is a highly
imaginative creative activity
nothing like the puzzle solving
described by furthermore
for science cannot be understood
without considering psychological and
sociological factors for him there is no
such thing as a neutral scientific
observation observations are always made
through the lens of a paradigm in
papillion science such factors are
foreign problems exist
and proposed solutions either pass the
rigorous attempts to refute them or they
do not thus coon's analysis of sciences
stresses convention and subjective
factors
and popper's analysis stresses logic and
creativity dn robinson suggests that the
views of both kuhn and popper may be
correct
in a conciliatory spirit we might
suggest that the major disagreement
between and popper vanishes when we
picture as describing what science
has been historically
and pauper asserting what it ought to be
however it should be noted that there is
a basic difference between poppers and
kuhn's philosophies of science popper
believed that there are truths about the
physical world that science can
approximate in other words popper
accepted the correspondence theory of
truth kuhn on the other hand rejected
this theory
saying instead that the paradigm
accepted by a group of scientists
creates the reality they explore for
this reason kuhn was led to the radical
view that truth itself is relative to a
paradigm other philosophers of science
claim that any attempt to characterize
science is misleading for them there is
no one scientific method or principle
and any description of science must
focus on the creativity and
determination of individual scientists
in this spirit the illustrious physicist
percy w bridgman said that scientists do
not follow any prescribed course of
action science is what scientists do
when there are as many scientific
methods as there are individual
scientists in his book against method
outline of an anarchistic theory of
knowledge paul fairey been aligned
himself with those philosophers of
science who claim that scientists follow
no prescribed set of rules in fact he
said that whatever rules do exist must
be broken in order for scientific
progress to occur fair rabin summarized
this position as follows my thesis is
that anarchism helps to achieve progress
in any one of the senses one cares to
choose even a law and order science will
succeed only if anarchistic moves are
occasionally allowed to take place for
nobody can say in abstract terms without
paying attention to idiosyncrasies of
person and circumstances
what precisely it was that led to
progress in the past
and nobody can say what moves will
succeed in the future in his book
farewell to reason fair raven continued
his anarchistic description of science
there is no one scientific method
but there is a great deal of opportunism
anything goes anything that is
that is liable to advance knowledge as
understood by a particular researcher or
research tradition in practice science
often oversteps the boundaries some
scientists
and philosophers try to put in its way
and becomes a free and unrestricted
inquiry successful research does not
obey general standards
it relies now on one trick
now on another and the moves that
advance it are not always known to the
movers a theory of science that devises
standards and structural elements of all
scientific activities and authorizes
them by reference to some rationality
theory may impress outsiders but it is
much too crude an instrument for the
people on the spot
that is for scientists facing some
concrete research problem even with the
revisions suggested by popper kuhn
and feyrebend many traditional aspects
of science remain empirical observation
is still considered the ultimate
authority
lawful relationships are still sought
theories are still formulated and tested
and determinism is still assumed
