وهذا هو كلام المتأخرين
This is the form of discourse known as later kalām.
Later kalām is characterized by a more explicit use of philosophical questions and technical classifications. A theologian might construct premises about being and possibility, critique an account of bodies, or use logic to test the validity of an inference.
Differences between earlier and later styles do not imply that later scholars accepted every philosophical claim, or that early theological argument lacked all rational reasoning. The objective of defending doctrine could remain while the supporting vocabulary, organization, and auxiliary sciences changed.
The essential distinction is between the doctrinal conclusion and the method used to argue for it.
