Still up to lore, answering that question. Type 1 concepts are self-reliant. A T1 for creation and destruction could have all that it represents warped or gone and remain as is. A T2 would not. Henceforth, independent and dependent.
Imagine a set. Let's call it C = {1, 2, 3}.
In a type 2 situation, “t2C” defines but is also defined by the totality of {1, 2, 3}. Destroy or warp all of {1, 2, 3} and the concept suffers the same consequences. If that set is now {4, 5, 6} or empty, so is type2C.
In a type 1 situation, “t1C” is self-reliant. All partakes in what it means but it does not need anything to partake in. Anything imaginable could be done to {1, 2, 3} and it would still not matter. The concept that “t1C = {1, 2, 3}” would remain outside reach.
From that, what we conclude is that the definition of conceptual type doesn't come from presupposed nature, but in how It is shown to interact with reality by each franchise.
