Otherness is among relational terms.
Calling one thing “other” normally involves a relation to something else, as with father and son or cause and effect. Each relation has its own conditions; the mere use of “other” does not predetermine that the two relata are independently subsisting beings.
The discussion also asks whether a relational account smuggles in an inadmissible separateness. The reply distinguishes relational contrast, real independence, and conceptual difference. The legitimacy of the relational expression depends on the precise relation being claimed.
