▁' new ▁perspective ' ▁according ▁to ▁Daniel ▁Rob b ins , ▁" was ▁a ▁mathematical ▁relationship ▁between ▁the ▁ideas ▁in ▁his ▁mind ▁and ▁the ▁exterior ▁world ". ▁The ▁' four th ▁space ' ▁for ▁Met z inger ▁was ▁the ▁space ▁of ▁the ▁mind . ▁▁ ▁In ▁a ▁second ▁letter ▁to ▁G le izes , ▁dated ▁ 2 6 ▁July ▁ 1 9 1 6 , ▁Met z inger ▁writes : ▁ ▁If ▁painting ▁was ▁an ▁end ▁in ▁itself ▁it ▁would ▁enter ▁into ▁the ▁category ▁of ▁the ▁minor ▁arts ▁which ▁appeal ▁only ▁to ▁physical ▁pleasure ... ▁No . ▁P ain ting ▁is ▁a ▁language — and ▁it ▁has ▁its ▁syntax ▁and ▁its ▁laws . ▁To ▁sh ake ▁up ▁that ▁framework ▁a ▁bit ▁to ▁give ▁more ▁strength ▁or ▁life ▁to ▁what ▁you ▁want ▁to ▁say , ▁that ▁isn ' t ▁just ▁a ▁right , ▁it ' s ▁a ▁duty ; ▁but ▁you ▁must ▁never ▁lose ▁sight ▁of ▁the ▁End . ▁The ▁End , ▁however , ▁isn ' t ▁the ▁subject , ▁nor ▁the ▁object , ▁nor ▁even ▁the ▁picture — the ▁End , ▁it ▁is ▁the ▁idea . ▁( M etz inger , ▁ 2 6 ▁July ▁ 1 9 1 6 ) ▁ ▁Cont inu ing , ▁Met z inger ▁mentions ▁the ▁differences ▁between ▁himself ▁and ▁Juan ▁Gr is : ▁Some one ▁from ▁whom ▁I ▁feel ▁ever ▁more ▁distant ▁is ▁Juan ▁Gr is . ▁I ▁adm ire ▁him ▁but ▁I ▁cannot ▁understand ▁why ▁he ▁we ars ▁himself ▁out ▁with ▁decom pos ing ▁objects .
