Lionking, the mere statement of an assumption does not make it causally false,
But, it's perfectly within the purview, especially within the context of this forum, to challenge the veracity of assumptions; especially when they are the basis for an argument about some social/historical truth. Your OP presumed the guilt of the US government as a method for proving that human nature has somehow changed since 9/11. You then point to what are perhaps factual changes in US domestic and foreign policy, and you attempt to show that this was the work of some vast conspiracy. In the process, you commit a non-sequitur fallacy of the type If A then B, B, therefore A.
The entirely correct response to what is basically a silly argument, is to challenge the assumption as being false, or unproven. Lionking, along with most of the other debunkers that responded have pointed this out. If you're interested in a completely useless debate (where we assume the existence of things for which no proof of their existence has been shown), then I demand that you spend equal time telling me how the combined force of Santa Clause and Unicorns also caused 9/11.
as Anti-Truthers contend ad nauseam on this forum. In the same way, the statement of a hypothesis does not signify it's falsity.
A hypothesis is untested, and therefore uninteresting. Again, I hypothesize that Unicorns destroyed the twin towers. Who cares?
Assumptions, related to deductive reasoning, are a central part in the act of thinking. As a proposition used to further prove other propositions, it is expected that the assumption will be discharged in due course by proving it via a separate argument.
So, let me get this straight. As a pre-condition for debating your point of view, we have to agree that the primary assumption, an assumption we know to be categorically false, is true? Are you on drugs? Has this line of reasoning ever worked for you?
The scientific finding of a military-grade energetic material in the WTC dust and corresponding witness testimonies to secondary explosives during the collapse of the towers may provide further evidence for the alternative conspiracy narrative. Nothing wrong, illogical, or incoherent here.
That's been discussed ad nauseum on this forum. Your assumptions here are demonstrably wrong.
Anti-Truthers themselves seem to rely heavily on the implausibility argument when debating the 911 controversy.
Wildly inaccurate. We actually rely on facts, logic, context, mathematics and the trappings of legitimate scientific inquiry. Truthers rely in a misrepresentation of the implausibility argument (First time in history...).
The alternative conspiracy narrative in regard to 911 is simply impossible, or implausible, because it does not make moral and technical (to them) sense.
A strange assumption, since to believe this they must also believe that, as stated through the mainline conspiracy narrative, we are living in a "post-911" world in which everything has changed.
In this case why base your assumptions today on assumptions you had before the 911 attacks (ie for example such a covert operation is impossible)? Hasn't "everything" changed?
So, in addition to factual inaccuracy, you've added misrepresentation to your strategy. Cute.
Unfortunately today we live in a world in which such an operation has the most possibility of occuring.
I am still blinded by the riddle, as it cannot be true.
Let me get this straight, a secret cabal of US government officials decides that they want to change US foreign policy, so they decide to use a material that has never been used to destroy a tall building, in order to destroy 3 tall buildings, only after 2 have been hit by two jet airliners. The third, which falls for apparently no reason is demolished in the same way as the first 2, but it falls several hours later. The complexity of this operation involves hundreds of people at minimum, with complete secrecy, and without any guilt driven leaks or confessions after 9 years. This shadowy cabal has some motive, but it really has nothing to do with the strength of the US military, the US economy, oil revenues, or simple monetary gain for any party involved. Rather, this cabal has some more esoteric goals involving social change, which benefits no one in the short term, and really doesn't benefit anyone in the long term.
That's more likely than a few dozen pissed off Islamo-fascists who are out to kill as a ticket to an eternity's worth of virgins?
Really?
