Summary: Methods of Scientific Research
Comment: Philosophy of Science is a crucial subset of philosophy, since it directly affects scientific research. We need to know what constitutes a properly constructed theory, and more to the point, which claims are not theoretical, or perhaps not even scientific. With that goal established, we need to know how to empirically verify the theory in question. Theories are developed within axiomatic systems, are based on assumptions, and present us with a compact thesis, or a set of theses. A theory is scientific if we can falsify it with empirical data. If a theory is not testable, then it is not a good theory, since we cannot accept or reject its propositions. An obvious point is to be raised here - when and under which conditions shall we reject a theory?
Methodological studies flourished in the XX century with the works of Karl Popper, Milton Friedman, Imre Lakatos, Harold Kuhn, Paul Feyerabend and other philosophers. The contribution of Imre Lakatos was significant. With his version of corroboration and refined fascificationism we were able to apply new standards towards the methods of rejection of scientific theories. A single rejection of the scientific theory is not likely to falsify it, unlike advocated previously. However, the main point is that while the absolute truth is always of importance, i.e. whether a given theory is considered "true" because we have not been able to negatively falsify that theory; it is more important that various theories can be compared to each other, even if they are all imperfect. To this end, we can specify a set of thresholds, and say that a research programme A is more empirically valid than a research programme B if it does withstand a larger number of empirical tests. Of course, as simple as it sounds, it is a useful method of evaluation of theories, and can be augmented as needed within a given science.
Philosophy of Science and methodology is of utmost importance to theorists, since more often than not, nonscientific methods of theory construction are used, and even worse, empirical data are inductively used to hypothesize about the causes for the pattern of these data. It's methodologically invalid and by construction, these theories are not falsifiable since they are derived from data. This is true especially within economic theory; labor economics and macroeconomics in particular.
The works of Lakatos are summarized and condensed in various descriptive volumes on the Philosophy of Science, however it is illuminating to read the original works of this ingenious philosopher, since by doing so you gain an additional layer of understanding.
I will not go as far as saying that it should have been a must reading for any scientist, since such proposition would be hardly realistic, but I will say that it is a treat for those who have already tasted methodology in a compact form, and would like to expand their knowledge.
