contrary；　it　is　the　moral　law　that　first　determines　the　concept　of　good　and　makes　it　possible；　so　far　as　it　deserves　the　name　of　good　absolutely。　　　This　remark；　which　only　concerns　the　method　of　ultimate　ethical　inquiries；　is　of　importance。　It　explains　at　once　the　occasion　of　all　the　mistakes　of　philosophers　with　respect　to　the　supreme　principle　of　morals。　For　they　sought　for　an　object　of　the　will　which　they　could　make　the　matter　and　principle　of　a　law　（which　consequently　could　not　determine　the　will　directly；　but　by　means　of　that　object　referred　to　the　feeling　of　pleasure　or　pain；　whereas　they　ought　first　to　have　searched　for　a　law　that　would　determine　the　will　a　priori　and　directly；　and　afterwards　determine　the　object　in　accordance　with　the　will）。　Now；　whether　they　placed　this　object　of　pleasure；　which　was　to　supply　the　supreme　conception　of　goodness；　in　happiness；　in　perfection；　in　moral　＇feeling＇；　or　in　the　will　of　God；　their　principle　in　every　case　implied　heteronomy；　and　they　must　inevitably　come　upon　empirical　conditions　of　a　moral　law；　since　their　object；　which　was　to　be　the　immediate　principle　of　the　will；　could　not　be　called　good　or　bad　except　in　its　immediate　relation　to　feeling；　which　is　always　empirical。　It　is　only　a　formal　law…　that　is；　one　which　prescribes　to　reason　nothing　more　than　the　form　of　its　universal　legislation　as　the　supreme　condition　of　its　maxims…　that　can　be　a　priori　a　determining　principle　of　practical　reason。　The　ancients　avowed　this　error　without　concealment　by　directing　all　their　moral　inquiries　to　the　determination　of　the　notion　of　the　summum　bonum；　which　they　intended　afterwards　to　make　the　determining　principle　of　the　will　in　the　moral　law；　whereas　it　is　only　far　later；　when　the　moral　law　has　been　first　established　for　itself；　and　shown　to　be　the　direct　determining　principle　of　the　will；　that　this　object　can　be　presented　to　the　will；　whose　form　is　now　determined　a　priori；　and　this　we　shall　undertake　in　the　Dialectic　of　the　pure　practical　reason。　The　moderns；　with　whom　the　question　of　the　summum　bonum　has　gone　out　of　fashion；　or　at　least　seems　to　have　become　a　secondary　matter；　hide　the　same　error　under　vague　（expressions　as　in　many　other　cases）。　It　shows　itself；　nevertheless；　in　their　systems；　as　it　always　produces　heteronomy　of　practical　reason；　and　from　this　can　never　be　derived　a　moral　law　giving　universal　commands。　　　Now；　since　the　notions　of　good　and　evil；　as　consequences　of　the　a　priori　determination　of　the　will；　imply　also　a　pure　practical　principle；　and　therefore　a　causality　of　pure　reason；　hence　they　do　not　originally　refer　to　objects　（so　as　to　be；　for　instance；　special　modes　of　the　synthetic　unity　of　the　manifold　of　given　intuitions　in　one　consciousness）　like　the　pure　concepts　of　the　understanding　or　categories　of　reason　in　its　theoretic　employment；　on　the　contrary；　they　presuppose　that　objects　are　given；　but　they　are　all　modes　（modi）　of　a　single　category；　namely；　that　of　causality；　the　determining　principle　of　which　consists　in　the　rational　conception　of　a　law；　which　as　a　law　of　freedom　reason　gives　to　itself；　thereby　a　priori　proving　itself　practical。　However；　as　the　actions　on　the　one　side　come　under　a　law　which　is　not　a　physical　law；　but　a　law　of　freedom；　and　consequently　belong　to　the　conduct　of　beings　in　and　consequently　the　consequently　belong　to　the　beings　in　the　world　of　intelligence；　yet　on　the　other　side　as　events　in　the　world　of　sense　they　belong　to　phenomena；　hence　the　determinations　of　a　practical　reason　are　only　possible　in　reference　to　the　latter　and；　therefore；　in　accordance　with　the　categories　of　the　understanding；　not　indeed　with　a　view　to　any　theoretic　employment　of　it；　i。e。；　so　as　to　bring　the　manifold　of　（sensible）　intuition　under　one　consciousness　a　priori；　but　only　to　subject　the　manifold　of　desires　to　the　unity　of　consciousness　of　a　practical　reason；　giving　it　commands　in　the　moral　law；　i。e。；　to　a　pure　will　a　priori。　　　These　categories　of　freedom…　for　so　we　choose　to　call　them　in　contrast　to　those　theoretic　categories　which　are　categories　of　physical　nature…　have　an　obvious　advantage　over　the　latter；　inasmuch　as　the　latter　are　only　forms　of　thought　which　designate　objects　in　an　indefinite　manner　by　means　of　universal　concept　of　every　possible　intuition；　the　former；　on　the　contrary；　refer　to　the　determination　of　a　free　elective　will　（to　which　indeed　no　exactly　corresponding　intuition　can　be　assigned；　but　which　has　as　its　foundation　a　pure　practical　a　priori　law；　which　is　not　the　case　with　any　concepts　belonging　to　the　theoretic　use　of　our　cognitive　faculties）；　hence；　instead　of　the　form　of　intuition　（space　and　time）；　which　does　not　lie　in　reason　itself；　but　has　to　be　drawn　from　another　source；　namely；　the　sensibility；　these　being　elementary　practical　concepts　have　as　their　foundation　the　form　of　a　pure　will；　which　is　given　in　reason　and；　therefore；　in　the　thinking　faculty　itself。　From　this　it　happens　that　as　all　precepts　of　pure　practical　reason　have　to　do　only　with　the　determination　of　the　will；　not　with　the　physical　conditions　（of　practical　ability）　of　the　execution　of　one's　purpose；　the　practical　a　priori　principles　in　relation　to　the　supreme　principle　of　freedom　are　at　once　cognitions；　and　have　not　to　wait　for　intuitions　in　order　to　acquire　significance；　and　that　for　this　remarkable　reason；　because　they　themselves　produce　the　reality　of　that　to　which　they　refer　（the　intention　of　the　will）；　which　is　not　the　case　with　theoretical　concepts。　Only　we　must　be　careful　to　observe　that　these　categories　only　apply　to　the　practical　reason；　and　thus　they　proceed　in　order　from　those　which　are　as　yet　subject　to　sensible　conditions　and　morally　indeterminate　to　those　which　are　free　from　sensible　conditions　and　determined　merely　by　the　moral　law。

　　It　will　at　once　be　observed　that　in　this　table　freedom　is　considered　as　a　sort　of　causality　not　subject　to　empirical　principles　of　determination；　in　regard　to　actions　possible　by　it；　which　are　phenomena　in　the　world　of　sense；　and　that　consequently　it　is　referred　to　the　categories　which　concern　its　physical　possibility；　whilst　yet　each　category　is　taken　so　universally　that　the　determining　principle　of　that　causality　can　be　placed　outside　the　world　of　sense　in　freedom　as　a　property　of　a　being　in　the　world　of　intelligence；　and　finally　the　categories　of　modality　introduce　the　transition　from　practical　principles　generally　to　those　of　morality；　but　only　problematically。　These　can　be　established　dogmatically　only　by　the　moral　law。　　　I　add　nothing　further　here　in　explanation　of　the　present　table；　since　it　is　intelligible　enough　of　itself。　A　division　of　this　kind　based　on　principles　is　very　useful　in　any　science；　both　for　the　sake　of　thoroughness　and　intelligibility。　Thus；　for　instance；　we　know　from　the　preceding　table　and　its　first　number　what　we　must　begin　from　in　practical　inquiries；　namely；　from　the　maxims　which　every　one　founds　on　his　own　inclinations；　the　precepts　which　hold　for　a　species　of　rational　beings　so　far　as　they　agree　in　certain　inclinations；　and　finally　the　law　which　holds　for　all　without　regard　to　their　inclinations；　etc。　In　this　way　we　survey　the　whole　plan　of　what　has　to　be　done；　every　question　of　practical　philosophy　that　has　to　be　answered；　and　also　the　order　that　is　to　be　followed。

　　Of　the　Typic　of　the　Pure　Practical　Judgement。

　　It　is　the　notions　of　good　and　evil　that　first　determine　an　object　of　the　will。　They　themselves；　however；　are　subject　to　a　practical　rule　of　reason　which；　if　it　is　pure　reason；　determines　the　will　a　priori　relatively　to　its　object。　Now；　whether　an　action　which　is　possible　to　us　in　the　world　of　sense；　comes　under　the　rule　or　not；　is　a　question　to　be　decided　by　the　practical　judgement；　by　which　what　is　said　in　the　rule　universally　（in　abstracto）　is　applied　to　an　action　in　concreto。　But　since　a　practical　rule　of　pure　reason　in　the　first　place　as　practical　concerns　the　existence　of　an　object；　and　in　the　second　place　as　a　practical　rule　of　pure　reason　implies　necessity　as　regards　the　existence　of　the　action　and；　therefore；　is　a　practical　law；　not　a　physical　law　depending　on　empirical　principles　of　determination；　but　a　law　of　freedom　by　which　the　will　is　to　be　determined　independently　on　anything　empirical　（merely　by　the　conception　of　a　law　and　its　form）；　whereas　all　instances　that　can　occur　of　possible　actions　can　only　be　empirical；　that　is；　belong　to　the　experience　of　physical　nature；　hence；　it　seems　absurd　to　expect　to　find
