Marx is not a scientist

So far this semester much of my time has been spent debating and trying to define what exactly science is.  This seems like a simple question at a glance, but the more one thinks about it, the more complicated the question at hand becomes.  After some practice the identification of pseudo-scientific theories becomes more simple, and more interesting.  It wasn't long into one of my classes that both Freud and Marx were thrown into the pit-which-is-not-science (I know that they both have many theories, and this is a gross generalization, but it fits them for the most part).  One of the biggest issues with the theories of the aforementioned is that they are (for the most part) non-falsifiable.  This means that no matter what observations are made, or theories created, they cannot disprove the statements of the theories in question.  This may seem as a strong point, but it really shows that the theories say nothing at all.  A Marxist can open any newspaper at any given time through history and find countless examples to 'verify' Marxist theory; the same can be said for a neo-Freudian.  I can't find the actual quote at the moment, but Emile Cioran once wrote something along the lines of: Something written for everyone, can say nothing.  This applies well in this situation; these non-falsifiable theories just point out things that are obvious throughout the world.  If I were to create a theory stating that the sun will set a length of time after it rises I would be 100% correct, but I wouldn't be saying anything; as one of my profs would say, it's true, but uninteresting.  If a theory can absorb and digest any concern thrown at it, or cannot conceivably be disproven (arguable with these cases) than it is not a scientific theory at all.  Something I was recently reading stated that Einstein's theory of relativity is a genuine scientific theory because it can be disproved (if one was to propel an object at a rate higher than that of light, which the LHC has shown to be impossible, therefore backing Einstein's theory).  Also, measurements taken during the 1919 solar eclipse showed that mass does in fact distort space(time).  In summary, theories that allow for everything, prove nothing. 

There are many more reasons for my accusations towards Marx (e.g. his colossal misunderstanding/generalizing of human behavior), but I don't really feel like going in to that at the moment.
