Great thinkers

Postmodernism:
a) All truth is limited, approximate, and is constantly evolving
b) No theory can ever be proved true (we can only show that a theory is false)
c) No theory can ever explain all things
d) Thus absolute and certain truth that explains all things is unobtainable.
 
"The ONLY ABSOLUTE TRUTH is that there are NO ABSOLUTE TRUTHS" (Feyerabend)
"Finally, if nothing can be truly asserted, even the following claim would be false,
the claim that there is no true assertion." (Aristotle)
"If anyone thinks nothing is to be known, he does not even know whether that can be known,
as he says he knows nothing." (Lucretius)
"And isn't it a bad thing to be deceived about the truth, and a good thing to know what the truth is?
For I assume that by knowing the truth you mean knowing things as they really are." (Plato)
 
Ludwig Wittgenstein 1889-1951
 
"Our investigation is a grammatical one. Such an investigation sheds light on our problem by clearing misunderstandings away. Misunderstandings concerning the use of words, caused, among other things, by certain analogies between the forms of expression in different regions of language."
 
“For a large class of cases–though not for all–in which we employ the word “meaning” it can be defined thus: the meaning of a word is its use in the language.”
 
Karl Marx
The gap between the rulling classes and the workers. Society needs to be restructured. Workers become the commodety themselves as well as what they are working on.
 
Lead to socialism.
