From Wikipedia:
Teleology (Greek: telos: end, purpose) is the philosophical study of design and purpose. A teleological school of thought is one that holds all things to be designed for or directed toward a final result, that there is an inherent purpose or final cause for all that exists.
And that is why I will continue to use the Science Lens as a primary source for reasoning the capability/function/potential of things,
I may however be mis-interpreting
What degree of minutae are you going to have to uncover the inherent purpose? Are you going to have to reason down to Molecular/Atomic/Sub Atomic/Theoretical Fundamental level, or do you take them as read and just plough on regardless using a nice big Macro Lens and just let sciency types look with the TEMs
How would you uncover this inherent final purpose? personal perception or maybe scientific reasoning? and is there any reason why something should continue to be 'WAD (working as Desinged)' after this perceived final purpose has been apparantly met?
Does the acceptance of Teleology as a method of reasoning require the existance of a designer at all levels or only at known designed works? if known does this include the proposal that there is an supernatural designer for all materials and processes?
There seems to be a lot of hurdles that would require that I need to utilise teleological reasoning after Scientific Reasoning/pragmatism and probably only when relating to known specific designs that seem to primarily of an aesthetic nature (after finding serving no derived technical or pragmatic function).
Depending on your personal level of Grand Unification Conspiracy Group beliefs you could argue that the destruction of the WTC had a pragmatic value when weighed against your own
paranoia beliefs, however just because an individual wants there to be additional levels of esign and purpose, does not mean that any additional details or grand design is required.
