particular of which being the brain-in-a-vat (BIV) experiment. Skeptics suggest that the BIV hypothesis can never be completely denied and this is thus evidence‚ that nothing substantial about the external world can ever be concluded. Hilary Putnam claims however‚ that when combined with semantic externalism‚ the BIV hypothesis cannot be true. This essay will demonstrate that Putnam’s argument against the BIV hypothesis is lacking. To accomplish this‚ this essay will: 1) define semantic externalism; 2) describe

Ed and Deb Sharpio’s hypothesis states that‚” If your heart says that you should do or believe something‚ then you should do or believe it.” To me‚ this is wrong. When you first hear their hypothesis‚ it doesn’t seem so far fetched. We were always told as kids and sometimes even now as young adults to “listen to you heart.” Countless songs‚ books‚ and stories convey this message‚ though I don’t think they meant it as literally as the Sharpios’s. If one were to take what Ed and Deb say literally

AP Biology Lab Four: Plant Pigments and Photosynthesis Abstract: The purpose of this lab is to separate and identify pigments and other molecules within plant cells by a process called chromatography. We will also be measuring the rate of photosynthesis in isolated chloroplasts. Beta carotene‚ the most abundant carotene in plants‚ is carried along near the solvent front because it is very soluble in the solvent being used and because it forms no hydrogen bonds with cellulose. Xanthophyll is found

However‚ no one hypothesis has been solely conclusive. In fact‚ hypotheses such as the Siberian volcanism‚ carbon isotope fluctuations and methane production all seem to be linked. The belief that Siberian volcanism was the main trigger for the extinction event seems to be the most valid since it also accounts for release of the CO2 and methane put forth by some researchers. The hypothesis that fluctuations in the carbon cycle and the subsequent release of methane is another hypothesis that has strong

Empirical Challenges to the Efficient Market Hypothesis 1. Introduction Random walks observed in stock return series prior to the 1970s puzzled a number of financial theorists and practitioners. In 1970‚ this puzzle was resolved by Eugene Fama (1970) who argued that the random walks observed in the behaviour of stock return series could be attributed to market efficiency. Market efficient meant that investors could not consistently make risk-adjusted returns by making investment decisions

what extent the ‘somatic-marker hypothesis’ explains how decisions are made in the face of an uncertain outcome. In mind of Kim Sterelny’s (2007) statement that ‘Human Life is one long decision tree’‚ it is not surprising that there has been a vast amount of research into the process of how we evaluate the desirability of alternative choices and select a particular option. One area of research‚ of particular interest here‚ is Damasio’s Somatic Marker Hypothesis (SMH) (1991) which uses the neuroeconomic

The contact hypothesis states that intergroup bias can be reduced by there being contact between social outgroups in appropriate environments. According to Oskamp and Jones (2000)‚ this is the most widely used psychological intervention for reducing prejudice. It has been suggested by Allport (1954) that the conditions needed for this to work are as follows: equality between the two groups has to be a social norm‚ as well as equality of status between the two groups and thirdly‚ there must be cooperation
