Theory and methods in political science pdf

Theories guide the enterprise of finding facts rather than of reaching goals, and are neutral concerning alternatives among values. To theorize is to develop this body of knowledge. These two things are related but can be independent, because it is possible to research health and sickness without curing specific patients, and it is possible to cure a theory and methods in political science pdf without knowing how the cure worked. The word has been in use in English since at least the late 16th century.

Pythagoras emphasized subduing emotions and bodily desires to help the intellect function at the higher plane of theory. Thus it was Pythagoras who gave the word “theory” the specific meaning that led to the classical and modern concept of a distinction between theory as uninvolved, neutral thinking, and practice. For Aristotle, both practice and theory involve thinking, but the aims are different. However, the truth of any one of these statements is always relative to the whole theory. Therefore, the same statement may be true with respect to one theory, and not true with respect to another. He” is and for that matter what a “terrible person” is under the theory.

As a result, some domains of knowledge cannot be formalized, accurately and completely, as mathematical theories. Here, formalizing accurately and completely means that all true propositions—and only true propositions—are derivable within the mathematical system. This limitation, however, in no way precludes the construction of mathematical theories that formalize large bodies of scientific knowledge. When an old and new theory are parallel in this way, we can conclude that the new one describes the same reality, only more completely. Sometimes theories are incorrect, meaning that an explicit set of observations contradicts some fundamental objection or application of the theory, but more often theories are corrected to conform to new observations, by restricting the class of phenomena the theory applies to or changing the assertions made. An example of the former is the restriction of classical mechanics to phenomena involving macroscopic length scales and particle speeds much lower than the speed of light.

The formal scientific definition of “theory” is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence. Many scientific theories are so well established that no new evidence is likely to alter them substantially. One of the most useful properties of scientific theories is that they can be used to make predictions about natural events or phenomena that have not yet been observed. A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not “guesses” but reliable accounts of the real world.

The theory of biological evolution is more than “just a theory. It is as factual an explanation of the universe as the atomic theory of matter or the germ theory of disease. Our understanding of gravity is still a work in progress. But the phenomenon of gravity, like evolution, is an accepted fact.

In this approach, theories are a specific category of models that fulfill the necessary criteria. The specific mathematical aspects of classical electromagnetic theory are termed “laws of electromagnetism”, reflecting the level of consistent and reproducible evidence that supports them. Within electromagnetic theory generally, there are numerous hypotheses about how electromagnetism applies to specific situations. Many of these hypotheses are already considered adequately tested, with new ones always in the making and perhaps untested. Acceptance of a theory does not require that all of its major predictions be tested, if it is already supported by sufficiently strong evidence.

For example, certain tests may be unfeasible or technically difficult. These predictions can be tested at a later time, and if they are incorrect, this may lead to revision or rejection of the theory. A field of study is sometimes named a “theory” because its basis is some initial set of assumptions describing the field’s approach to the subject. These assumptions are the elementary theorems of the particular theory, and can be thought of as the axioms of that field.
