Epistemic essay in justification knowledge theory

It should also be underscored that the deontic appearance of ordinary epistemic discourse seems to have a distinctively categorical flavor; that is, the phenomenology of our everyday talk and thought about duties, obligations, oughts, seems to imply the existence of categorical duties and obligations such as duties that are in some sense unconditional, that is independent of our psychology (desires, dispositions, beliefs,) and constrain what we ought to believe insofar as we are rational. For example, if a speaker utters, “You should believe that p” in an ordinary conversational context her statement would, typically, conversationally implicate that it is an (epistemic) fact of sorts that “You should believe that p.” A fortiori, the conversational implication is that anyone epistemically rational would be obliged to believe that p because it constitutes a categorical epistemic obligation (derivative of a corresponding epistemic fact).

In fact, Mandelbrot also argues for this strategy.  Taleb co-authored a paper arguing that most people systematically underestimate volatility. Furthermore, he argues there exists not only a lack of appreciation of fat tails, but a preference for positive skew , in that people prefer assets that jump up, not down, which would imply the superiority of buying out-of-the-money puts as opposed to calls because those negative tails that increase the price of puts are is affiliate with some fund that tend to be long tail risk, presumably by being long deep out-of-the-money options, but selling at-the-money options, a locally delta and vega neutral strategy.

These assertions present some straightforward tests, which a Popperian like Taleb should embrace. Specifically, buying out-of-the-money options, especially puts (because of negative skew), should, on average, make money. But insurance companies, which basically are selling out-of-the-money options, tend to do as well as any industry (Warren Buffet has always favored insurance companies, especially re-insurers, as equity investments). Studies by Shumway and Coval (2001) and Bondarenko (2003) have documented that selling puts is where all the extranormal profit seems to be. Of all the option strategies, selling, not buying, out-of-the-money puts has been the best performer historically. Further, Sophie Ni finds that out-of-the-money options are more overexpensive the degree they are out-of-the-money.

20. Non-State Actors have emerged in international relations as important actors. They are limiting the authorities being enjoyed by sovereign nation-state under state-centric international relations based on principles of Westaphalian system. By weakening states, NSAs are establishing themselves at domestic as well as international level and they influence the international security to a greater extent. The degree and nature of influence may vary from one NSA to other; it could be positive or negative as well as at large or small scale. Whatever role the major NSAs are playing in international relations, needs to be studied in order to explore their influence in international security.
