This is a set of questions and issues aimed at Truthers, but they are also open for discussion for the entire skeptic community.
Over in the The north side evidence validated to the point of redundancy thread, I've been struck by a feature of CIT's theory which is actually generalizable to all 9/11 CTs and to CTs in general: denial of contingency.
How am I using 'contingency' here, and what do I mean by the above observation?
Contingency is the opposite of necessity. When something is necessary, it could not have happened any other way. Both premises and conclusions can be necessary. If something is contingent, it could have happened another way, or not happened at all.
Both conditions and conclusions, causes and effects, can be either necessary or contingent.
For instance, in traditional deductive logic, a conclusion must be accepted if 1) the argument is valid and 2) the premises are true. For example, given
1. All mammals are warm-blooded.
2. A tiger is a mammal.
3. Therefore a tiger is warm-blooded.
we must accept (3) if the argument is valid (it is) and if the premises (1) and (2) are true. 3 is thus a necessary conclusion.
Similarly, there can be necessary conditions. For instance, for pure water to freeze at STP, the ambient temperature must be less than or equal to 0 degrees Celcius - this is a necessary condition.
Contingency is trickier - a contingent condition or conclusion is one in which it doesn't necessarily have to be the case. For instance, take the argument:
If I jump off a cliff, I will die.
The conclusion "I will die" is contingent on many factors - if I have a parachute, or if there's a lot of fluffy pillows at the bottom of the cliff, I won't die. Or I might - what if the parachute is not packed correctly? In most cases, I'll slam into the ground and die. My death is contingent on many factors.
Similarly, conditions can be contingent. For instance:
I look outside and see the street is wet. I reason:
The street is wet; a condition for this to occur is that it recently rained.
This argument is based on a contingent condition - yes, it is the case that if it rains, my street will be wet, but not necessarily! It could have happened another way. For instance, it could have snowed. Or, a helicopter could have flew by and dropped a load of water on the ground. Or, a bunch of kids with hoses could have wet the street. Or, even if it does rain, one could put a tarp on the street, preventing it from getting wet. Rain is not a necessary condition for the street being wet - it is a contingent condition.
What does this have to do with 9/11? The real world is so complex that we can rarely discover all the necessary conditions or conclusions to any cause or effect. Our world is too complex, there are too many variables. We deal with contingency every day. Buf if you look at any conspiracy theory about 9/11, you'll find that CTers live in a world of necessity.
Every aspect of that day had purpose. Everything was planned to the minutest detail. Take the collapse of WTC7. To a skeptic, we see contingency - given different starting conditions, WTC7 could have stood up. Same with the towers, or even the 9/11 event itself - given different conditions, things could have happened a different way. This is contingency; we accept this.
Truthers do not see this, however - everything (or the most important things) that occurred that day happened necessarily. WTC7 HAD to fall given that it DID fall. The problem at heart with their thinking, I think, is that they cannot accept that WTC7 might not have fallen. They can't accept that WTC1&2 might not have collapsed. They can't accept that 9/11 might not have happened! They live in a world of necessity; all that happens is explainable and planned; similarly, all plans and conditions lead to necessary conclusions.
In CITs world, the fact that one of the lamp posts crashed into Lloyd England's world was necessary for the operation - and of course it must be! The only way it fits into their world is if the lamp post and Mr. England were set up ahead of time, planned, necessary. Because it happened, it MUST have happened. Their Weltanschauung is one with relatively few necessary premises; thus, they can construct a world of relatively few necessary conclusions.
The question for truthers is, then: What aspects of 9/11 were 'contingent,' and which were 'necessary?' Are there any aspects of the day that were not 'planned' ahead of time? How would we know?
The question for everyone else is: In what other places (9/11 CTs or no) do you see this type of thinking, where everything that happens has a purpose, a clearly defined set of necessary conditions that lead to necessary conclusions? And what does this tell us about knowledge in general?
ETA: I am not a philosopher, and I apologize if I'm not using these terms in a precise way. You don't have to necessarily agree with me!
