[2]: 66 Popper argues that science should adopt a methodology based on "an asymmetry between verifiability and falsifiability; an asymmetry which results from the logical form of universal statements. For these are never derivable from singular statements, but can be contradicted by singular statements".
Non-justificationism is also accepted by David Miller and Karl Popper. [9] However, not all proponents of critical rationalism oppose justificationism; it is supported most prominently by John W. N. Watkins. In justificationism, criticism consists of trying to show that a claim cannot be reduced to the authority or criteria that it appeals to.
Evidence contrary to a hypothesis is itself philosophically problematic. Such evidence is called a falsification of the hypothesis. However, under the theory of confirmation holism it is always possible to save a given hypothesis from falsification. This is so because any falsifying observation is embedded in a theoretical background, which can ...
The University of Klagenfurt acquired Popper's library in 1995. The Karl Popper Archives was established within the Klagenfurt University Library, holding Popper's library of approximately 6,000 books, including his precious bibliophilia, as well as hard copies of the original Hoover material and microfilms of the incremental material.

The founder of critical rationalism: Karl Popper. In the mid-twentieth century, several important philosophers began to critique the foundations of logical positivism.In his work The Logic of Scientific Discovery (1934), Karl Popper, the founder of critical rationalism, argued that scientific knowledge grows from falsifying conjectures rather than any inductive principle and that ...
To Popper, pseudoscience uses induction to generate theories, and only performs experiments to seek to verify them. To Popper, falsifiability is what determines the scientific status of a theory. Taking a historical approach, Kuhn observed that scientists did not follow Popper's rule, and might ignore falsifying data, unless overwhelming.
Critical rationalism, an epistemological philosophy founded by Karl Popper; Three models of scientific progress in "Falsification and the Methodology of Scientific Research Programmes" by Imre Lakatos. Dogmatic falsificationism; Naive falsificationism; Sophisticated falsificationism
Stove argued that Popper's counterexamples to Lakatos were either instances of begging the question, such as Popper's example of missiles moving in a "non-Newtonian track", or consistent with Newtonian physics, such as objects not falling to the ground without "obvious" countervailing forces against Earth's gravity.
