Background In the modern technological and highly specialized world scientists are seldom aware of the work of philosophers; it is practically unparalleled to find them queuing up, as they have done in Popper's case, to swear to the great practical beneficial influence which that philosophical work has had upon their own (1). In his paper he started by the following “The problem which troubled me at the time was neither, 'When is a theory true?' nor, 'When is a theory acceptable?' My problem was different I wished to distinguish between science and pseudo-science; knowing very well that science often errs, and that pseudo-science may happen to stumble on the truth” (2) Karl considers the empirical method of observations ensued by test or series of tests to approve a theory, and analysis of the results (empirical method) is not acceptable. As an alternative he recommended the following “I often formulated my problem as one of distinguishing between a genuinely empirical method and a non-empirical or even a pseudo-empirical method--that is to say, a method which, although it appeals to observation and experiment” (2) He established that the main problem in the philosophy of science is that of demarcation, i.e., (distinguishing between science and what he terms 'non-science). Karl popper summarized his ideas in seven points as followed: 1. It is easy to obtain confirmations, or verification, for nearly every theory-if we look for confirmations. 2. Confirmations should count only if they are the result of risky predictions 3. Every 'good' scientific theory is a prohibition: it forbids certain things to happen. 4. A theory which is not refutable by any conceivable event is non scientific. 5. Every g... ... middle of paper ... ...ns no observation is free from the possibility of error. 6- Karl popper considered that scientific logic is deductive logic. so all scientific theories are tested by trying to falsify them. In order to do this, scientists deduce predictions from theories and if the predictions prove to be false, then deductive logic dictates that the theory is false. If the predictions prove to be true, then the theory is not proven true, simply this means that is corroboration to this theory. 7-last one (conventionalist twist) or a’ conventionalist stratagem'.)these words created to explain the trying some admirers of some theories to rescue the theory from refutation tried to save their theory, By introducing some auxiliary assumption, or by re-interpreting the theory in this way that it escapes refutation, but they destroyed or at least lowered, its scientific status (2).

A hypothetico-deductivists may find a several number of problems in Chalmers scientific view. Through the use of induction to the objectiveness of science. Popper would argue falsification and how we comprehend life and the universe to change between individual people. Concluding that on Chalmers he would disagree with every statement made. With my personal perspective I am inclined to side with the hypothetico-deductivists as when forming an argument against Chalmers they have a much more accurate judgment on the world, so I am forced to reach a decision with the interpretation Popperian science has bought into the modern scientific world.
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,
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...
This essay aims to discuss the problems of the common view of science which was presented by Alan Chalmers by Popperian's view and my personal opinions. Chalmers gives his opinion about what science is and the judgment will be made in this essay through the Popperian hypothetico-deductive and my arguments will be presented in this essay. Popperian is an important philosopher of science who developed hypothetico-deductive method, which is also known as falsificationism. In my opinion, I disagree Chlamer points of view of science and this will be present in essay later. I will restrict my arguments into three parts due to the word limitation. Three aspects will be discussed in this essay: justifying the view through the Popper's view, my agreement about the Popper's objections and additional personal opinions.
In the book, Jim Holt interviews people from theologists like Richard Swinburne, to philosophers of science such as Adolf Grunbaum, from theoretical physicists like David Deutsch, Regular physicists such as Steven Weinberg, to Platonist’s like Roger Penrose. In my essay, I have chosen to look at the ideas established by the philosopher Adolf Grunbaum as well as the theologist of Swinburne. Jim Holt describes the exchanges between them as an 'intricate metaphysical ping pong match.' Both of these theologists are very ...
Any hypothesis, Gould says, begins with the collection of facts. In this early stage of a theory development bad science leads nowhere, since it contains either little or contradicting evidence. On the other hand, Gould suggests, testable proposals are accepted temporarily, furthermore, new collected facts confirm a hypothesis. That is how good science works. It is self-correcting and self-developing with the flow of time: new information improves a good theory and makes it more precise. Finally, good hypotheses create logical relations to other subjects and contribute to their expansion.
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.
Ever wonder how the world would be today only if our great researchers implemented a different attitude towards their experiments? It is possible that the results would remain same. However, some argue that the consequences may be altered. Nonetheless, this does not make the earlier learned knowledge valued less or false, just supplementary. Abraham Maslow’s theory challenges nearly all ways of knowing, suggesting that if we limit our thinking, the outcomes remain homogenous, therefore, limiting the amount of knowledge we acquire. Dilemmas are mentioned in order to repudiate from the opinions that are profoundly accepted in the society. If Newton had eaten that apple, instead of using it as a tool to apply the theory of attraction, he may not have exposed gravity. Because he had more tools than a mere hammer and he was sagacious enough to expand his philosophy beyond hunger, he made such an innovation. It is widely claimed that inventions are accidental. In fact, all the chemical elements in the famous periodic table are a result of different tactics towards scientist’s research. As ToK teaches us that there is no possible end to a situation for it is influenced by the perceptive skills of the arguers. There is never a ‘yes’ or ‘no’ or the ‘ultimate answer’ in the conflict, but the eminence of rationalization is what poises the deliberation. This suggestion explains that there is always that one more way to approach the conclusion. Thus, pursuit of knowledge habitually requires dissimilar ways of knowing for it lengthens the verdict.

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
Traditional theory contains many propositions that are related due to their consistency with a fact. By separating the facts from the object we are only able to see things as they are and not what they could be. According to Horkheimer, this is limiting. Traditional theory is only useful when trying to understand how society works and limits our capabilities to think of how society could progress or change. By being able to critique change in society we are able to understand the society we live in more. Traditional theory however is not wrong for the belief in collection of data. While knowing and understanding things as they are is important, this theory alone does not suffice for the main prop...
The word theory emanated from the Greek word meaning “contemplate” It has been viewed by scholars in different ways. Theory can be defined literally as an explanation of phenomena and its associations with variables that it is attempting to predict. There are no general agreed definitions of theory because scholar’s views of what constitute theory differ based on the purpose, nature and what make up of a good theory (Gelso, 2006; Harlow, 2009; Stam, 2007, 2010; and Wacker 1998). For instance, Wacker, (1998), pointed out that a theory must have four basic criteria such as conceptual definitions, domain limitations, relationship-building, and predictions. He, also, opined that for any theory to be regarded as a good theory, it must have qualities for `good ' theory, such as “uniqueness, parsimony, conservation, generalizability, fecundity, internal consistency, empirical riskiness, and abstraction, which apply to all research methods” (p.364). Stam (2010) interpreted theory as ...
Nature of science or NOS is a term that refers to the epistemic knowledge of science, the knowledge of constructs and values that are intrinsic to the subject. The constructs and values include historical groundwork to scientific discovery and social incorporation such as sociology, philosophy, and history of science (“Nature of Science”). Nature of science, in my opinion, should not be explicitly taught in high school science curriculum. The basis for my standing on the issue is representative of the lack of a fundamental standard understanding of what Nature of Science is, as well as the lack of effectiveness in explicitly teaching Nature of Science which I will expand on further in
