The fallacy of the '''stolen concept''', also known as the fallacy of the '''self-negating statement''', is the [[logical fallacy]] of implicitly affirming what one wants to disprove or, alternatively, implicitly denying what one wants to prove. That is, the [[conclusion]] [[contradiction|contradicts]] one of the [[premise]]s. More formally, the fallacy starts with a premise ''P'' and somehow reaches the conclusion not-''P''. The term "stolen concept" refers to a concept that is "stolen" from the [[quoting out of context|context]] that gives that concept meaning.
==Examples==
*[[Socialist]]s claim that property is theft, but the concept of theft presupposes a right to own property.
