The organizing principle of every pattern is limitation.
Limitation is a relation between a portion and an extent.
The portion and extent can be either:
We may visualize limitation as one shape being bounded by another.
If a jigsaw puzzle piece is a portion and the remainder of the puzzle is an extent then the piece's presence in the puzzle is a limitation.
The portion cannot exceed the extent, but the extent need not be any more than the portion (.ie a puzzle of one piece)
We are not speaking of sets, but we need a symbol for limitation, and this one comes close enough to our intuition of limitation as an act of inclusion or enclosure.
An ADEPT LION occasion is a synthesis of its inputs. These inputs are the occasions at the other end of its channels. The synthesis is expressed as limitations. These limitations are interpreted in a process much like an algebraic calculation in mathematics. But rather than numbers, there are occasions of pattern. And rather than having multiple operators (addition, subtraction, division and multiplication), there is only limitation. And just as there are laws in mathematics to govern the use of operations (.ie associative, commutative), there are laws in pattern language to govern the operations of limitation.
A Limitation: ⊇
An Occasion: a Greek letter like "α"
Absence of an occasion: ∅
An occasion that limits itself entails itself
α ⊇ α ⊢ α
"alpha"
No occasion, being both limited by an initial occasion, and limiting another subsequent occasion, entails that the initial occasion does not limit the subsequent occasion.
α ⊇ ∅ ⊇ β ⊢ ¬α ⊇ [β]
"all that is not alpha limits this beta"
An occasion that limits no occasion entails its complement.
α ⊇ ∅ ⊢ ¬α
"all that is not alpha"
An occasion that is limited by no occasion entails the selection of itself.
∅ ⊇ α ⊢ [α]
"this alpha"
An occasion, which is limited by one occasion and limits another entails that the central occasion is an approximation of the limitation that exists between the other two occasions.
α ⊇ β ⊇ γ ⊢ β ≈ α ⊇ γ
"beta approximates alpha limiting gamma"
An occasion, simultaneously limiting two occasions entails that the central occasion is an approximation of the union of the other two occasions.
α ⊆ β ⊇ γ ⊢ β ≈ α ∪ γ
⊢ β ≈ γ ∪ α
"beta approximates the union of alpha and gamma"; "beta approximates the union of gamma and alpha"
An occasion, simultaneously limited by two occasions entails that the central occasion is an approximation of the overlap of the other two occasions.
α ⊇ β ⊆ γ ⊢ β ≈ α ∩ γ
⊢ β ≈ γ ∩ α
"beta approximates the overlap of alpha and gamma"; "beta approximates the overlap of gamma and alpha"
No occasion, being simultaneously limited by two occasions entails the complement of either of these occasions properly limiting the other.
α ⊇ ∅ ⊆ β ⊢ α ⊂ ¬β
⊢ ¬α ⊃ β
"alpha is properly limited by all that is not beta"; "all that is not alpha properly limits beta"
No occasion, simultaneously limiting two occasions entails the complement of either of these occasions approximates the other.
α ⊆ ∅ ⊇ β ⊢ α ≈ ¬β
⊢ ¬α ≈ β
"alpha approximates all that is not beta" ; "all that is not alpha approximates beta"
An occasion, that limits some other occasion entails that the other occasion is limited by the initial occasion.
α ⊇ β ⊢ α ⊇ β ⊆ α
⊢ β ⊆ α ⊇ β
⊢ β ⊆ α
"alpha limits beta limited by alpha"; "beta limited by alpha limits beta"; "beta limited by alpha"
When the limitation laws are applied sequentially in a consideration of an occasion, they are necessary and sufficient to derive interpretations for all of the pattern occasion types that the fixed schema of the ADEPT LION pattern language establishes.
The compound application of the laws in an act of interpretation is called a sequence.
