RT Article T1 Rigid and Non-Rigid Forms JF Process studies VO 36 IS 2 SP 272 OP 290 A1 Ford, Lewis S. 1933- LA English YR 2007 UL https://ixtheo.de/Record/1823933947 AB Eternal objects are rigid, being invariant in all their appearances in the world, as well as in the becoming of actual entities. This rigidity within concrescence generates several difficulties, and so I propose that forms within concrescence, both divine and finite, be modifiable. Thus there can be a formation of form. Each eternal object then becomes completely determinate in a finite actualization, and remains so determinate throughout its worldly career. DO 10.2307/44799035
