The Role of the Subject Matter of Simplicity or Combination of Derivation in the Formation of Shaykh Ishraq's Proofs for the Being Mentally Posited and Its Answers

Shaykh Ishraq is the upholder of the mentally Posited (i'tibàri) of existence (wujud). He represents three arguments to prove this issue according to the binary of simplicity (bisatat) or the combination of derivation. Sadr al-Muta'allihin with presenting a new analysis of the combination (tarakob) of derivation (moshtaq) and separating the boundary of the conceptual specifications from existential characteristics freed himself from all Suhrawardi's difficulties. Muzaffar tries to base the simplicity (bisatat) of derivation to answer Suhrawardi's proof but far from many problems which deal with the theory of simplicity (bisatat) of derivation, on the supposition of simplicity (bisatat) of derivation, Suhrawardi has found out problems for the external realization of Being (Wujud) which should be answered. Allameh Tabataba'i believes that the origin of Suhrawardi's evidence is wrong and therefore, any attempt to answer it is approving a kind of wrong proof in philosophical tradition. The mentioned argument and every argument of language foundation makes us involve in intermingling reality with mental consideration and in general it is not expected metaphysic matter of the mentally posited issues.
