The problem Popper was trying to solve was that of demarcation and the meaning of science. Popper said the demarcation problem was the one of fundamental problems in the philosophy of science. It is important to distinguish between what is science and what is bullshit in any area of knowledge. To better deal with the differences, Popper formulated falsification, which was a substitute to the logical positivists’ verification principle and became a principle for differentiating between science and pseudoscience. The first section of this paper will cover the principle of falsification and its use in solving the problem of demarcation and induction. The second section will have some critiques of the principle.
The demarcation problem is the philosophical issue trying to determine what hypotheses should be considered scientific and what types should be considered pseudoscientific or non-scientific. Popper rejected verifiability as a way to completely verify a scientific statement. In the philosophy of science, verificationism says that a statement must be empirically verifiable for it to be both

The way to demarcate between theories is to name those that are scientific with one or more falsifiers. “Formally, then, Popper's theory of demarcation may be articulated as follows: where a ‘basic statement’ is to be understood as a particular observation-report, then we may say that a theory is scientific if and only if it divides the class of basic statements into the following two non-empty sub-classes: (a) the class of all those basic statements with which it is inconsistent, or which it prohibits—this is the class of its potential falsifiers (i.e., those statements which, if true, falsify the whole theory), and (b) the class of those basic statements with which it is consistent, or which it
Popperian hypothetico deductivists would find several problems with the view of science Alan Chalmers stated in ‘What is this thing Called Science?’ From “Scientific knowledge is proven knowledge” to “Scientific knowledge is reliable knowledge because it is objectively proven” popper would disagree to everything. With Chalmers falsificationism or hypothetico-deductivism view, his statement indicates that scientific induction is completely justifiable. However as it is now known, induction is not a reasonable way to prove or justify science.
In science, a theory will refer to an explanation of an important feature of the world supported by testing and facts that have been gathered over time. It’s there scientific theories that allow scientists to make predictions about untested and unobserved concurrences in the world. The American Association for the Advancement of Science has this explanation of what a theory means to those in the science field, and it is as follows, “A scientific theory is a well substantiated explanation of some aspect of the natural world, based on a body of facts......Such fact supported theories are not guesses but reliable accounts of the real
A paradox stems from a statement that apparently contradicts itself yet might still be true. In most cases logical paradoxes are essentially known to be invalid but are used anyways to promote critical thinking. The Raven’s paradox is an example of a paradox that essentially goes against what most logical paradoxes stand for in that it tries to make a valid claim through inductive logic. Carl Hempel is known for his famous accepting of this paradox with minor adjustments by the use of the contraposition rule. In this paper, however, I argue that Hempel’s solution to the Raven’s paradox is actually unsuccessful because he fails to take into account a possible red herring that serves as evidence against his solution. Irvin John Good is responsible for the formulation of the red herring argument as he tries to prove that the observation of a black raven can potentially negate the Raven’s paradox as valid. In addition to Good’s claim, Karl Popper and his view of falsificationism also functions as evidence to reject Hempel’s solution. Using Popper’s view as a basis, Israel Scheffler and Nelson Goodman formulate the concept of selective confirmation to reject the contraposition rule used by Hempel. Based off of all of the rejections that Hempel’s solution has it can clearly be seen that the Raven’s paradox has flaws that principally lead it to it being invalid.
The unificationist account of explanation and the notion of ad hoc-ness as posited by Popper are very similar concepts, but there is a nuance between the two that is worth explaining. Although both notions seem to show why we choose certain explanatory theories over others, they differ in that the model of unification shows us what type of theory we should accept, while Popper’s notion of ad hoc-ness shows us what type of theory to reject. Together, these concepts help us better understand the explanatory model of unification which leads us to a better understanding of why we are inclined to accept certain scientific theories over others. In this paper, I will attempt to show that falsifying theories based on Popper’s ad hoc-ness criteria strengthens the idea of unification by giving people a more specific way of eliminating competing scientific theories in search of the most unified one. First, I will briefly describe the unificationist account of explanation, then I will explain the idea of ad hoc-ness as laid out by Popper, and finally I will show how ad hoc-ness can be used to strengthen the account of unification by means of increasing its objectivity and by providing simpler explanations.
The authority of the theory of evolution can be characterized by defining what qualifies as a scientific theory. Although there are several perspectives regarding what science is, they are based on the same premises. Karl Popper, a philosopher of science, claims that the process of “conjectures and refutations” is the method of science (46). In this process, a
Pseudo sciences resting on the priori method carefully stated their information and follow logical rules to arrive at acceptable conclusions. In this approach, the conclusions are derived by using logic through some a set of facts and/or declarations. The a priori method is more intellectual and respected approach compared with other methods such as tenacity and authority. Furthermore, is t has shown to be quite strong in the hands of that mathematicians and philosophers. Nevertheless, accurate scientific conclusions depend on both the reasoning and the exactness of the premises. This is where it comes the use of the scientific method; science meets reasoning and empiricism, using logical reasoning, but by means of a careful methodology, (Graziano & Raulin, 2010; Rosnow & Rosenthal,
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,
Scientists are constantly forced to test their work and beliefs. Thus they need the ability to embrace the uncertainty that science is based on. This is a point John M. Barry uses throughout the passage to characterize scientific research, and by using rhetorical devices such as, comparison, specific diction, and contrast he is able show the way he views and characterizes scientific research.
In addition to logical consistency, testability is an important piece when evaluating a theory. According to Akers & Sellers (2013), “a theory must be testable by objective, repeatable evidence” (p.5); thus, if the theory is not testable then it has no scientific value. There are several reasons why a theory might not be testable; such as its concepts may not be observable or reportable events and tautology. Tautology refers to a statement or hypothesis that is tr...
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...
Firstly, I shall expound the verification principle. I shall then show that its condition of significant types is inexhaustible, and that this makes the principle inapplicable. In doing so, I shall have exposed serious inconsistencies in Ayer's theory of meaning, which is a necessary part of his modified verification principle.
Also, being able to demarcate between science and non science and pseudo science is part of being scientifically literate, to not only be able to read and understand scientific findings and journals but to be able to critically distinguish between valid, trustworthy findings and theories or ideas presented in a scientific format without actually adhering to the scientific method and other requirements for scientific research.
The following essay will discuss falsification, as discussed by Karl Popper, as well has his account of the scientific method. The idea whether any scientific theory can truly be falsified will also be approached by looking at the problems presented by Popper’s theory of falsification, and the impact this has on the scientific method and science as a whole.
Moritz Schlick believed the all important attempts at establishing a theory of knowledge grow out of the doubt of the certainty of human knowledge. This problem originates in the wish for absolute certainty. A very important idea is the concept of "protocol statements", which are "...statements which express the facts with absolute simplicity, without any moulding, alteration, or addition, in whose elaboration every science consists, and which precede all knowing, every judgment regarding the world." (1) It makes no sense to speak of uncertain facts, only assertions and our knowledge can be uncertain. If we succeed therefore in expressing the raw facts in protocol statements without any contamination, these appear to be the absolutely indubitable starting points of all knowledge. They are again abandoned, but they constitute a firm basis "...to which all our cognitions owe whatever validity they may possess." (2) Math is stated indirectly into protocol statements which are resolved into definite protocol statements which one could formulate exactly, in principle, but with tremendous effort. Knowledge in life and science in some sense begins with confirmation of facts, and the protocol statements stand at the beginning of science. In the event that protocol statements would be distinguished by definite logical properties, structure, position in the system of science, and one would be confronted with the task of actually specifying these properties. We fin...
A scientific theory is an explanation that is well- substantiated explanation in regards to some aspect of the natural world that is attained through scientific method and is tested numerous times and usually confirmed through vigorous observation and experimentation. The term theory can be seen as a collection of laws which allow you to show some kind of phenomenon. The strength of a scientific theory associated with the diversity of phenomena can explain its elegance and simplicity. However when new evidence is gathered a scientific theory can be changed or even rejected if it does not fit the new findings, in such cases a more accurate theory is formed. Scientific theories are used to gain further
