What is the notion of incommensurability?
The term ‘incommensurable’ means ‘to have no common measure’. The idea has its origins in Ancient Greek mathematics, where it meant no common measure between magnitudes. For example, there is no common measure between the lengths of the side and the diagonal of a square.
Are there incommensurable values?
Values, such as liberty and equality, are sometimes said to be incommensurable in the sense that their value cannot be reduced to a common measure.
What does Khun mean when he says that scientific paradigms are incommensurable?
Kuhn claimed that science guided by one paradigm would be ‘incommensurable’ with science developed under a different paradigm, by which is meant that there is no common measure for assessing the different scientific theories.
Are paradigms incommensurable?
Feyerabend argued that frameworks of thought, and thus scientific paradigms, can be incommensurable for three reasons. Paradigms can be based on different assumptions regarding the structure of their domain, which makes it impossible to compare them in a meaningful way.
What are commensurable numbers?
In mathematics, two non-zero real numbers a and b are said to be commensurable if their ratio ab is a rational number; otherwise a and b are called incommensurable. (Recall that a rational number is one that is equivalent to the ratio of two integers.)

How do you prove Incommensurability?
The Proof:
- Suppose AC and AB are commensurable; let a/b be their ratio expressed in the smallest possible numbers.
- Since AC > AB, it follows that a > b.
- Now from (I) we get: (AC2/AB2) = (a2/b2) (II).
- By the Pythagorean Theorem, AC2 =AB2+BC2, and since AB=BC, we can infer AC2=2AB2. (
What are Euclid’s commensurable and incommensurable magnitudes?
Commensurable magnitudes are said to be those measured by the same measure, and incommensurable those for which it is not possible for anything to become a common measure of them. and incommensurable whenever it is not possible for any area to become a common measure of the squares on them.
What is incommensurability in economics?
On this interpretation, incommensurability is defined as the relation that holds between two items when neither is better than the other nor are they equally as good. Others have not given an exact definition of the term, but use it as an inclusive umbrella term for comparability problems in general.
Are scientific theories incommensurable?
Since 1962, the incommensurability of scientific theories has been a widely discussed, controversial idea that was instrumental in the historical turn in the philosophy of science and the establishment of the sociology of science as a professional discipline.
Is incommensurability of knowledge important?
Incommensurability and its implications have been controversially discussed ever since the inception of Western science as we know it. Incommensurability has played a starring role in a variety of controversial discussions about the nature of knowledge, from Plato, Aristotle, and Euclid to Albert Einstein, Thomas S. Kuhn, and Paul Feyerabend.
What is Kuhn’s theory of incommensurability?
Feyerabend and Kuhn were concerned with incommensurability between rival theories or paradigms — that is, the inability to express or comprehend one conceptual scheme, such as Aristotelian physics, in terms of another, such as Newtonian physics.
