Demarcation is a philosophical problem with far reaching implications in our daily lives, both theoretically and practically. The issue of demarcation stems from the idea of how to distinguish science from pseudoscience and attempts to establish a set of criterion from which individuals can determine the empirical nature of a certain theory. Philosophical musings regarding demarcations have been around for the past hundreds of years. For the philosophers that we read, this time was during the era when Marx, Freud, Adler and Einstein were all proposing or had recently proposed their respective theories. Philosophers such as Popper, Kuhn and Lakatos all sought to determine the scientific nature of Freudian’s Id and Ego as well as Marx’s political beliefs. Popper, the earliest of the philosophers we read regarding the issue of demarcation proposed that a certain theory can only be deemed science if that theory had the ability to be proven false. Kuhn, on the other hand, attempted to define the problem of demarcation as that which solves puzzles rather than testing theories. Finally, Lakatos notes that a theory can be proven scientific if and only if it has the ability to prove an unusual future event. While all these philosophers indeed have powerful arguments, I found those to be proposed by Popper and Lakatos the most intriguing. My view on demarcation closely parallels that of Lakatos, however I do understand Popper’s position but notice pitfalls in his argument. The problem

While analyzing Kurosawa Akira’s Rashomon in the essay, “Irreconcilable Realities”, Aaron M. Kerner writes, “The substance of the film hinges on what is irreconcilable, and “resolving” the narrative would run contrary to the film’s central concern.” In this quote, Kerner is addressing the fact that the film does not have a conclusion where the audience knows the truth about the characters in the film. Rashomon instead addresses the natures of reality and real life through his filming of this unusual mystery story. He addresses storytelling through the eyes of different characters and shows how the different points of view can have a major impact on the telling of the story. By telling the story this way the film creates a commentary on
Mark Christianson identifies three main ideas throughout Stephen Jay Gould’s “the Geometer of Race,” which are; scientists’ theories can never be completely objective, scientists must realize that their scientific theories have a powerful ideological impact on society, and that scientific theories form a “mental geometry” that remains in people’s minds.
Every genuine test of a scientific theory, then, is logically an attempt to refute or to falsify it, and one genuine counter-instance falsifies the whole theory. In…theory of demarcation is based upon … perception of the logical asymmetry which holds between verification and falsification: it is logically impossible to conclusively verify a universal proposition by reference to experience …, but a single counter-instance conclusively falsifies the corresponding universal law. In a word, an exception, far from ‘proving’ a rule, conclusively refutes it (Thornton,
Imagine in 40 years, human beings and aliens live in the same planet, a huge scientific and cultural revolution must occur to interchange the knowledge and ways of pursuing and interpreting knowledge between the two living things. In order to peacefully live on the same planet, there must be some consensus towards methods of interpretation for the community to accept new theories and reject old ones. In the essay by Dr. Minos Talgia in The New Yorker, the author describes a community where the old theories like general relatively and quantum physics are rejected, methods like the Hypothetical-deductive method is also reject. Instead, the community comes to a consensus to accept all theories by the aliens in the empirical science, which is
What is Science? When it comes to the word ‘science’ most of the people have some kind of knowledge about science or when they think of it there is some kind of image related to it, a theory, scientific words or scientific research (Beyond Conservation, n.d.). Many different sorts of ideas float into an individual’s mind. Every individual has a different perception about science and how he/she perceives it. It illustrates that each person can identify science in some form. It indicates that the ‘science’ plays a vital role in our everyday lives (Lederman & Tobin, 2002). It seems that everyone can identify science but cannot differentiate it correctly from pseudo-science and non-science (Park, 1986). This essay will address the difference between science, non-science and pseudo-science. Then it will discuss possible responses to the question that what should we do when there is a clash between scientific explanation and non-scientific explanation. Then it will present a brief examination about the correct non-scientific explanation.
The Division and Separation of power are essential to keep our societies rulers to have a restriction on their powers. The importance of each on the Australian domestic law especially in relation to the rule of law, and protecting individual rights, and the legal system.
However, since the personality divisions are not physical, there is no way to prove that they do or do not exist. As a result of the conflicts between the Id, ego and Super Ego, Freud argued that the mind prepared ego defence mechanisms to reduce anxiety. These were Repression, Displacement, Projection, Denial and Intellectualisation. Myers and Brewin provided support for this theory in their study.
Both Marxist and positivist stress the need for a rigorous scientific method, for scientific analysis of the social phenomenon and natural world.
The following essay aims to discuss the inconsistencies between the inductivist and Popper’s points of view of science rationality of science in light of claims that the scientific method is inductive yet an inductive method is no. I think is rational to say that inductivist view of science has significant contradiction that Popper’s view solves. To support Popper’s view my argument will introduce the inductivist and falsificationsist views and I will focus in showing the issues of considered science as objective, scientific knowledge as proven and nature as uniform as well as the differences between inductivism and falsificationism to the creation of hypothesis.
In the article, "Science: Conjectures and Refutations", Karl Popper attempts to describe the criteria that a theory must meet for it to be considered scientific. He calls this puzzle the problem of demarcation. Popper summarizes his arguments by saying, "the criterion of the scientific status of a theory is its falsifiability, or refutability, or testability." Kuhn
Karl Popper is commonly regarded as one of the greatest philosophers of science in the 20th Century. He is well known for his rejection of the inductivist viewpoint of the scientific method, in which one uses observation to propose a law to generalize an observed pattern, and later confirm that law through more observation. Popper states that “induction cannot be logically justified” (Popper 14). Inductivism relies on the process of inductive reasoning which is a logical process in which multiple premises, all thought to be true and found to be true most of the time, are combined to obtain a conclusion and in many cases formulate a law or theory. Popper rejected the inductivist viewpoint in favor of a theory called empirical falsification which holds that a theory can never be proven, but it can be falsified, and therefore it can and needs to be scrutinized through experimentation.
Popper and Kuhn held differing views on the nature of scientific progress. As seen in Popper’s falsification theory, he held that theories can never be proved only disproved or falsified. Once a theory is proved false we move on to the next. Kuhn, on the other, hand argued a new paradigm may solve puzzles better than the old one but you cannot describe the old science as false. Both seem to share the Kantian idea that the really real, independently existing world is completely unknowable. Kuhn further asserts that the empirical world, which is knowable, is partly constructed by our categories and concepts. The fundamental difference in their views are best stated in Kuhn’s own words, “A very different approach to this whole network of problems has been developed by Karl R. Popper who denies the existence of any verification procedures at all. Instead he emphasizes the importance of falsification, i.e., of the test that, because its outcome is negative, necessitates the rejection of an established theory. Clearly, the role thus attributed to falsification is much like the one this essay assigns to anomalous experiences, i.e., to experiences that, by evoking crisis, prepare the way for a new theory. Nevertheless, anomalous experiences may not be identified with falsifying ones.”(Kuhn, 145) As seen by this passage, the fundamental difference between Popper and Kuhn is that Popper disregards “verification” and Kuhn asserts that “falsification” only takes place once a
Laudan (1983) claimed that the problem of demarcation can be traced back to ancient Greece and Aristotle. Aristotle asserted that from general laws one can deduce scientific theories that are consequently truthful statements. Pseudoscientific theories according to Aristotle are not deductively formulated and therefore cannot be considered scientific. However this method of demarcation is flawed: pseudosciences such as astrology can be vacuously true and most are reluctant to say astrology is scientific. We can already see from this early stage that the distinctions between science and pseudoscience are murky and the formulation of demarcation can be challenging.
As people, we come with earlier knowledge and understandings on subjects and topics of study, “Science” being one of them. We make presumptions, based on either reasonable evidence or that our thoughts and ideas are known as true by others. Through this we have come to understand and define science as its aims, leaving its definition, whether consciously or unconsciously, unchallenged. We have taken advantage of the label that we have set for science, as well as its goals, and failed to look at them further.
We live in a strange and puzzling world. Despite the exponential growth of knowledge in the past century, we are faced by a baffling multitude of conflicting ideas. The mass of conflicting ideas causes the replacement of knowledge, as one that was previously believed to be true gets replace by new idea. This is accelerated by the rapid development of technology to allow new investigations into knowledge within the areas of human and natural sciences. Knowledge in the human sciences has been replaced for decades as new discoveries by the increased study of humans, and travel has caused the discarding of a vast array of theories. The development of
