Does science consist in the progressive development of objective truth? Contrast the views of Kuhn with one other writer on this topic.
The philosopher and historian of science Thomas Kuhn introduced the term paradigm as a key part of what he called “normal science”: In normal (that is non revolutionary) periods in a science, there is a consensus across the relevant scientific community about the theoretical and methodological rules to be followed. (Marshall 1998). Paradigms tend to shift over time as new scientific discoveries are made, and anomalies or observations that conflict with the current paradigm begin to accumulate. Eventually this leads to a scientific revolution. There is a shift from one paradigm to another and a new period of normal science begins. So, what seems to be scientifically relevant at one time may not be so in years to come. An example of a paradigm shift would be when it was discovered that Earth was not the centre of the universe and that the sun did not revolve around the earth. This was a widely held belief up until, and even after there was proof to show that these beliefs were held falsely. Kuhn argued that the way scientists choose what conceptual and theoretical framework (what "paradigm") they should apply in framing their scientific questions and in seeking to resolve scientific puzzles is necessarily heavily influenced by subjective factors, including prevailing social norms and conventions. This implies that scientific theories are subjective and therefore so is the “truth” they aim to show.
Kuhn argued that an old scientific paradigm is occasionally displaced by a new one and that in some senses the scientist finds himself working in a “different world”. For Kuhn, what counts as true in one paradigm is different from what counts as true in a different paradigm. Another way of putting this is that truth does not survive a scientific revolution. This means that Kuhn can be seen as a relativist as his argument suggests that there is no external reality by which we are able to measure the truth of scientific theories and that the truth changes with each new paradigm. Thomas Kuhn observed that science, as it's actually practiced, isn't the logical and cumulative building up of a true picture of the world that it was generally believed to be. He showed that there is no fixed, defined criterion for deciding bet...

...not there is an objective truth or reality. His main point is that scientific progress is a continuing refinement of our ideas about what might be the case. He says there's no single criterion for selecting one theory over another, not even success at predicting phenomena. The only judge is the consensus of the scientific community, and that clearly changes so it can't be used in advance to decide one theory over another. Popper also argued that we can never be sure that our theories will never be falsified and so all knowledge or truth is provisional and can change. It seems therefore that although Popper seems to follow a realist account of scientific progress and Kuhn a relativist one, that actually they both believed that there is progress in science but that we could not know if we were progressing towards an objective truth.

Kuhn sees most of normal science as "mop up work" because most of the time older scientific paradigms are replaced and evolve into newer scientific paradigms; using this premise one can come to the conclusion that Kuhn believes the majority of people who believe that science is cumulative is wrong. Since scientific paradigms do not cumulate upon one another, older scientific paradigms must be mistaken so that newer scientific paradigms can come about. The older scientific paradigms are necessary because without them there would be no "mop up work" to be revolutionized. Finally, there are three phases that science goes through: the pre paradigm phase, normal science, revolutionary science. As can be seen by the preceding information scientific revolutions go through very specific phases and they are necessary for the evolution of science.
Kuhn (1996), defined a paradigm a set of theoretical concepts and research, unified by a framework that describes what is/ isn’t accepted in a specific area of scientific research. Paradigms have two distinguished aspects, namely a set of core experiments that are exemplary and therefore likely to be reproduced and underpinning preconceptions that condition the evidence collected in the experiments. However early theorists considered paradigms conceptually inappropriate for the social sciences such as psychology compared to their natural science counterparts, citing that there are no paradigms in social science as the concepts are polysemic (Kuhn, 1996; Dogan, 2001). Paradigms have also been described as a perspective of the world or worldview (Fassinger, 2005), a term used to describe a specific set of experiences, beliefs and values that the individual uses in order to interpret reality.
Longino defines her account of scientific knowledge relative to positivist and wholist accounts. Though many regard positivism as offering an untenable account of science, because "no comparable sweeping and detailed philosophical view has replaced it," Longino believes that it still needs to be reckoned with (L1990, 21). Wholists are significant because they have been the greatest critics of positivism. After presenting these accounts, and explaining the difficulties that Longino has with them, I will present Longino's own account of scientific knowledge and inquiry.

Since the mid-20th century, a central debate in the philosophy of science is the role of epistemic values when evaluating its bearing in scientific reasoning and method. In 1953, Richard Rudner published an influential article whose principal argument and title were “The Scientist Qua Scientist Makes Value Judgments” (Rudner 1-6). Rudner proposed that non-epistemic values are characteristically required when making inductive assertions on the rationalization of scientific hypotheses. This paper aims to explore Rudner’s arguments and Isaac Levi’s critique on his claims. Through objections to Levi’s dispute for value free ideal and highlighting the importance of non-epistemic values within the tenets and model development and in science and engineering,
Without theories, scientists’ experiments would yield no significance to the world. Theories are the core of the scientific community; therefore figuring out how to determine which theory prevails amongst the rest is an imperative matter. Kuhn was one of the many bold scientists to attempt to bring forth an explanation for why one theory is accepted over another, as well as the process of how this occurs, known as the Scientific Revolution. Kuhn chooses to refer to a theory as a ‘paradigm’, which encompasses a wide range of definitions such as “a way of doing science in a specific field”, “claims about the world”, “methods of fathering/analyzing data”, “habits of scientific thought and action”, and “a way of seeing the world and interacting with it” (Smith, pg.76). However in this case, we’ll narrow paradigm to have a similar definition to that of a ‘theory’, which is a system of ideas used to explain something; it can also be deemed a model for the scientific community to follow. Kuhn’s explanation of a Scientific Revolution brings to light one major problem—the problem of incommensurability.
The Chalmers's view against the Popperian hypothetico-deductive. Popper mentioned that people shouldn't concentrate our hopes on an unacceptable principle of induction.Also, he claimed that without relying on induction we still can work out how science works and why it is rational.1 Hence, I would like to said Popper would disagree with Chalmer's opinion. Also, I think Popperian might say Chalmers is wrong because his falsifiable in Popperian sense. Chalmers might be falsified if scientific knowledge is observed not reliable due to some experiment and observation might contain mistakes and we do not find them now. Furthermore, the Popperian might argue that science can not be prove but can justify the better theories or laws.1 We can justify which scientific laws or theories are better ones as there is falsified is found, or not scientific. When they are found falsified or not scientific, we can seek for novel bold hypot...

"We often think of science as something inescapably linked to progress, and of progress as continually marching forward. We assume that there is something inevitable about the increase of knowledge and the benefits this knowledge brings" (Irvine & Russell). Provide humanity with wisdom and speculative enjoyment. This enjoyment of the public is through reading, learning and thinking. But scientists are met with the real research work.
