Is Freudian theory falsifiable (by Popper's criteria) Essay

Is Freudian theory falsifiable (by Popper's criteria) - Essay Example The matter is the fact that at those times there was a strong belief that works of these scientists are absolutely scientific. But Popper had different point of view. According to him Einstein’s theory was distinguished from theories of Freud, Adler and Marx due to its openness to be falsifiable, i.e. to criticism. Popper considered that Freud, Marx, and Adler gave some true and important issues, despite he thought their theories to be unscientific. In general our intellectual culture has been largely influenced by Popper’s criticism of Freudian theory and his castigation of inductivism. Thus, Frederick Crews, the literary critic states that Popper has proved his own denial of Freudian explanations and Peter Medawar, biologists, has approved both of Karl Popper’s complaints with gusto. In 1935 in the philosophical analysis of the scientific method Karl Popper represented his famous criterion of falsifiability, which is now considered to be an important concept of science as well as of philosophy of science. According to this criterion any theory, proposition or hypothesis can be considered â€Å"scientific† only when it is falsifiable. Thus, Popper’s criterion is necessary but not sufficient for evaluation of any ideas claiming to be scientific (Sokal, 1998). Any theory satisfies Popper’s criterion (i.e. it is falsifiable and therefore scientific) in the event that there is a methodological opportunity to refute it by setting one or another experiment, even if such an experiment has not yet been delivered. According to this criterion, a statement, or system of statements contain information about the empirical world only if it is able to come into collision with the experience, or more accurately - if it can be systematically checked, that is subjected to (according to some â€Å"methodological solutions†) checks, which may result in its denial. In other words, according to Popper's criterion, a scientific theory cannot be fundamentally unassailable. Thus, according to this doctrine, the problem of demarcation (i.e. separation of scientific knowledge from the unscientific) is solved. Popper called this unequal "power" and role in the verification of meaning and truth of scientific theories inherent in confirming and refuting factors â€Å"cognitive asymmetry†. Based on this â€Å"asymmetry† Popper proclaimed the replacement of the â€Å"principle of verification† (i.e. a positive or confirmed check), used by logical empiricists, with the principle of â€Å"falsification† (that is the principle of reliable denial). It means that the verification of scientific essence, and then of the truth of scientific theories must be carried out not through their confirmation, but mainly (or exclusively) through their denial. Popper's criterion requires that a theory or hypothesis should not be fundamentally unassailable. According to Popper a theory cannot be considered scient ific only on the grounds that there is one, several or infinitely many experiments, confirming it. Since almost any theory, formed on the basis of at least some of the experimental data, permits the conducting of a large number of supporting experiments, the existence of confirmation cannot be considered a token of scientific theory. According to Popper, theories differ with respect to the possibility of setting up an experiment able, at least in principle, give a

Tax Deal (Current Event) - Essay Example e final, concluding section of the paper will offer an overview of the situation and consider the merits of the various positions and the probable outcome. In simplest terms the current debate revolves around the Presidents campaign promise to not extend significant changes to personal income tax rules that were introduced under President George W. Bush. Under President Bush two significant bills reducing personal income taxes were introduced: The Economic Growth and Tax Relief Reconciliation Act of 2001 and the Jobs and Growth Tax Relief Reconciliation Act of 2003. The chart on the following page outlines the impact of these two tax bills on personal tax levels. In simplest terms the bills lowered the personal income tax rate on the lowest level of income (below USD 7,150) and on the highest levels (USD 29,050). Those earning between USD 7,150 and 29,050 remained constant. However, as is often the case with government legislation the devil is in the details. The bills also changed the dollar figures around the highest tax brackets pushing them upwards slightly. For example, in 2000 one entered the highest tax bracket if they earned USD 288, 351 but by 2003 that number had increased to USD 311,951. Therefore a person who earned USD 300,000 in both those years was paying 39.6% in 2000 but only 33% in 2003. (â€Å"Federal Tax Brackets†) Also, under President Bush significant changes in other aspects of personal income, notably on capital gains. Capital gains tax is levied on the market value received on sale of an asset beyond its book value or purchase price. If an asset is bought for $50 and sold for $75, the realized capital gain (profit) is $25. Capital gains generally increase as ones personal wealth increases as it implies having personal wealth to invest. A person working in a minimal wage job rarely has large sums to invest. The exact opposite is true of a person who has a substantial income. Therefore, as a general rule, decreases in the capital gains
