　the　idea　of　an　object　and　that　relation　of　this　idea　to　the　subject　by　which　its　faculty　of　desire　is　determined　to　its　realization。　Such　a　relation　to　the　subject　is　called　the　pleasure　in　the　realization　of　an　object。　This；　then；　must　be　presupposed　as　a　condition　of　the　possibility　of　determination　of　the　will。　But　it　is　impossible　to　know　a　priori　of　any　idea　of　an　object　whether　it　will　be　connected　with　pleasure　or　pain；　or　be　indifferent。　In　such　cases；　therefore；　the　determining　principle　of　the　choice　must　be　empirical　and；　therefore；　also　the　practical　material　principle　which　presupposes　it　as　a　condition。　　　In　the　second　place；　since　susceptibility　to　a　pleasure　or　pain　can　be　known　only　empirically　and　cannot　hold　in　the　same　degree　for　all　rational　beings；　a　principle　which　is　based　on　this　subjective　condition　may　serve　indeed　as　a　maxim　for　the　subject　which　possesses　this　susceptibility；　but　not　as　a　law　even　to　him　（because　it　is　wanting　in　objective　necessity；　which　must　be　recognized　a　priori）；　it　follows；　therefore；　that　such　a　principle　can　never　furnish　a　practical　law。

　　　　　　　　　　　　　　　　　　　　　III。　THEOREM　II。

　　All　material　practical　principles　as　such　are　of　one　and　the　same　kind　and　come　under　the　general　principle　of　self…love　or　private　happiness。　　　Pleasure　arising　from　the　idea　of　the　idea　of　the　existence　of　a　thing；　in　so　far　as　it　is　to　determine　the　desire　of　this　thing；　is　founded　on　the　susceptibility　of　the　subject；　since　it　depends　on　the　presence　of　an　object；　hence　it　belongs　to　sense　（feeling）；　and　not　to　understanding；　which　expresses　a　relation　of　the　idea　to　an　object　according　to　concepts；　not　to　the　subject　according　to　feelings。　It　is；　then；　practical　only　in　so　far　as　the　faculty　of　desire　is　determined　by　the　sensation　of　agreeableness　which　the　subject　expects　from　the　actual　existence　of　the　object。　Now；　a　rational　being's　consciousness　of　the　pleasantness　of　life　uninterruptedly　accompanying　his　whole　existence　is　happiness；　and　the　principle　which　makes　this　the　supreme　ground　of　determination　of　the　will　is　the　principle　of　self…love。　All　material　principles；　then；　which　place　the　determining　ground　of　the　will　in　the　pleasure　or　pain　to　be　received　from　the　existence　of　any　object　are　all　of　the　same　kind；　inasmuch　as　they　all　belong　to　the　principle　of　self…love　or　private　happiness。

　　　　　　　　　　　　　　　　　　　　　　　　COROLLARY。

　　All　material　practical　rules　place　the　determining　principle　of　the　will　in　the　lower　desires；　and　if　there　were　no　purely　formal　laws　of　the　will　adequate　to　determine　it；　then　we　could　not　admit　any　higher　desire　at　all。
