Chapter 4: The Main Argument¶

[PLANNED] This chapter has not yet been written; what follows is a skeleton. Items may be added or removed, and the order may change.

The derivation itself. The relationality premise P is legislated first — target: analytic truth; whatever exists has identity conditions that involve difference and relation, with Piṅgala's "where there is self-being there is other-being" as the earliest witness.

• The three ways of legislating P (analytic, a priori, empirical) and the choice, with its price.
• The opponent's standard escape: epistemic versus ontic dependence, with Saṅghabhadra standing in the gap; the cost of closing it.
• The core derivation: E3 and D2 jointly require and forbid relational identity conditions — contradiction. The middle strength as fallback: arguments must use relational resources that the conclusion declares void.
• The weak strength: the twenty-seven chapters as exhaustive reductio, and the strong version as the extraction of their one recurring lever.
• Worked samples: the chapter on motion as instantiation over a relational domain; the chapter on conditions picking up the handover from Part 16.
