This is how I view the issue (from your above statements I think we agree so just letting you know you are not insane):
We don’t know or understand what quantum phenomenon is. We have abstracted knowledge about said phenomenon that can and does bear fruit.
For material objects, like keys and such, we do not have certainty as any term (like a key) that doesn’t possess universal quality (there are a plurality of keys not a singular universal ‘key’), cannot contain certainty and therefore is knowledge based on semantic interpretation.
‘U-Knowldge’ (universal knowledge) operates differently as it is complete within a set limit under set rules. ‘S-Knowledge’ (semantic knowledge) is open to some degree of interpretation. S-Knowledge is reality driven because we do not know everything about reality (U-Knowledge is only abstracted, bounded and operating under strict rules that are known and understood).
What JTB is is a formal set of rules set up in abstraction and then extended to ‘reality’. Such ‘knowledge’ is S-Knowledge only and cannot be confirmed as U-Knowledge.
What is True is used in formal logic (which is a universal abstract) yet when this is extended to human speech and action in the lived world there is U-Knowledge. The working principles of U-Knowledge can clearly be used well in reality (this is why I mentioned quantum phenomenon as a good example to show this) even though we have little or no understanding or knowledge of what is going on. The universal abstract of mathematics can be used to model and predict what we observe with quantum phenomenon to a practical end. The certainty lies in the mathematics not in reality because the rules and limits of the mathematics used are known explicitly.
Knowledge, such as historical knowledge -or experiential knowledge of whether it is raining or not - is ‘knowledge’ bound in lived-experience. All human experience is an artifice of some proposed reality. We can dream about the rain hitting our skin and ‘truly belief’ that it is raining when it is not raining in ‘reality’. This is precisely why I refer to this kind of S-Knowledge as being defined as ‘that which we are attending to’ (in phenomenological terms Intentionality).
It is my JTB that U-Knowledge can be, and is, applied to reality because science bears results. There is no JTB that it can be applied indefinitely (extended infinitely) as we are only able to apply it to limited data sets not all possible data sets - because our scope/capacity as humans is limited.
Just to go back to the ‘rain’ issue … the semantic problem is defining what is meant by ‘rain’. Again we find the same issue as with ‘key’. Rain is not a ‘universal term’ meaning when we say ‘rain’ it is not one explicit ‘rain’ understood by everyone as we can question it: How heavy? When? Where? We cannot question abstract universals and only abstract universals can be used to create definitive answers.
Does that all make sense or am I going insane?
