A four-dimensional approach to this subfield is held by Perdurantists (“per-DUR-un-tists”), as for them entities extended in time consist of this subfield’s objects of study. Stanisław Leśniewski (-5[1])(“stan-EE-swaff lesh-NYEF-skee”) named this subfield as part of a threefold system with ontology and protothetic.

For 10 points, (-5[2])what subfield of metaphysics (-5[1])studies the relationship between wholes (10[2])and parts? (10[1])■END■ (10[2]0[13])
