　the　subjective　ground　of　determination　of　the　will　of　a　being　whose　reason　does　not　necessarily　conform　to　the　objective　law；　by　virtue　of　its　own　nature；　then　it　will　follow；　first；　that　not　motives　can　be　attributed　to　the　Divine　will；　and　that　the　motives　of　the　human　will　（as　well　as　that　of　every　created　rational　being）　can　never　be　anything　else　than　the　moral　law；　and　consequently　that　the　objective　principle　of　determination　must　always　and　alone　be　also　the　subjectively　sufficient　determining　principle　of　the　action；　if　this　is　not　merely　to　fulfil　the　letter　of　the　law；　without　containing　its　spirit。*

　　*We　may　say　of　every　action　that　conforms　to　the　law；　but　is　not　done　for　the　sake　of　the　law；　that　it　is　morally　good　in　the　letter；　not　in　the　spirit　（the　intention）。

　　Since；　then；　for　the　purpose　of　giving　the　moral　law　influence　over　the　will；　we　must　not　seek　for　any　other　motives　that　might　enable　us　to　dispense　with　the　motive　of　the　law　itself；　because　that　would　produce　mere　hypocrisy；　without　consistency；　and　it　is　even　dangerous　to　allow　other　motives　（for　instance；　that　of　interest）　even　to　co…operate　along　with　the　moral　law；　hence　nothing　is　left　us　but　to　determine　carefully　in　what　way　the　moral　law　becomes　a　motive；　and　what　effect　this　has　upon　the　faculty　of　desire。　For　as　to　the　question　how　a　law　can　be　directly　and　of　itself　a　determining　principle　of　the　will　（which　is　the　essence　of　morality）；　this　is；　for　human　reason；　an　insoluble　problem　and　identical　with　the　question：　how　a　free　will　is　possible。　Therefore　what　we　have　to　show　a　priori　is　not　why　the　moral　law　in　itself　supplies　a　motive；　but　what　effect　it；　as　such；　produces　（or；　more　correctly　speaking；　must　produce）　on　the　mind。　　　The　essential　point　in　every　determination　of　the　will　by　the　moral　law　is　that　being　a　free　will　it　is　determined　simply　by　the　moral　law；　not　only　without　the　co…operation　of　sensible　impulses；　but　even　to　the　rejection　of　all　such；　and　to　the　checking　of　all　inclinations　so　far　as　they　might　be　opposed　to　that　law。　So　far；　then；　the　effect　of　the　moral　law　as　a　motive　is　only　negative；　and　this　motive　can　be　known　a　priori　to　be　such。　For　all　inclination　and　every　sensible　impulse　is　founded　on　feeling；　and　the　negative　effect　produced　on　feeling　（by　the　check　on　the　inclinations）　is　itself　feeling；　consequently；　we　can　see　a　priori　that　the　moral　law；　as　a　determining　principle　of　the　will；　must　by　thwarting　all　our　inclinations　produce　a　feeling　which　may　be　called　pain；　and　in　this　we　have　the　first；　perhaps　the　only；　instance　in　which　we　are　able　from　a　priori　considerations　to　determine　the　relation　of　a　cognition　（in　this　case　of　pure　practical　reason）　to　the　feeling　of　pleasure　or　displeasure。　All　the　inclinations　together　（which　can　be　reduced　to　a　tolerable　system；　in　which　case　their　satisfaction　is　called　happiness）　constitute　self…regard　（solipsismus）。　This　is　either　the　self…love　that　consists　in　an　excessive　fondness　for　oneself　（philautia）；　or　satisfaction　with　oneself　（arrogantia）。　The　former　is　called　particularly　selfishness；　the　latter　self…conceit。　Pure　practical　reason　only　checks　selfishness；　looking　on　it　as　natural　and　active　in　us　even　prior　to　the　moral　law；　so　far　as　to　limit　it　to　the　condition　of　agreement　with　this　law；　and　then　it　is　called　rational　self…love。　But　self…conceit　reason　strikes　down　altogether；　since　all　claims　to　self…esteem　which　precede　agreement　with　the　moral　law　are　vain　and　unjustifiable；　for　the　certainty　of　a　state　of　mind　that　coincides　with　this　law　is　the　first　condition　of　personal　worth　（as　we　shall　presently　show　more　clearly）；　and　prior　to　this　conformity　any　pretension　to　worth　is　false　and　unlawful。　Now　the　propensity　to　self…esteem　is　one　of　the　inclinations　which　the　moral　law　checks；　inasmuch　as　that　esteem　rests　only　on　morality。　Therefore　the　moral　law　breaks　down　self…conceit。　But　as　this　law　is　something　positive　in　itself；　namely；　the　form　of　an　intellectual　causality；　that　is；　of　freedom；　it　must　be　an　object　of　respect；　for；　by　opposing　the　subjective　antagonism　of　the　inclinations；　it　weakens　self…conceit；　and　since　it　even　breaks　down；　that　is；　humiliates；　this　conceit；　it　is　an　object　of　the　highest　respect　and；　consequently；　is　the　foundation　of　a　positive　feeling　which　is　not　of　empirical　origin；　but　is　known　a　priori。　Therefore　respect　for　the　moral　law　is　a　feeling　which　is　produced　by　an　intellectual　cause；　and　this　feeling　is　the　only　one　that　we　know　quite　a　priori　and　the　necessity　of　which　we　can　perceive。　　　In　the　preceding　chapter　we　have　seen　that　everything　that　presents　itself　as　an　object　of　the　will　prior　to　the　moral　law　is　by　that　law　itself；　which　is　the　supreme　condition　of　practical　reason；　excluded　from　the　determining　principles　of　the　will　which　we　have　called　the　unconditionally　good；　and　that　the　mere　practical　form　which　consists　in　the　adaptation　of　the　maxims　to　universal　legislation　first　determines　what　is　good　in　itself　and　absolutely；　and　is　the　basis　of　the　maxims　of　a　pure　will；　which　alone　is　good　in　every　respect。　However；　we　find　that　our　nature　as　sensible　beings　is　such　that　the　matter　of　desire　（objects　of　inclination；　whether　of　hope　or　fear）　first　presents　itself　to　us；　and　our　pathologically　affected　self；　although　it　is　in　its　maxims　quite　unfit　for　universal　legislation；　yet；　just　as　if　it　constituted　our　entire　self；　strives　to　put　its　pretensions　forward　first；　and　to　have　them　acknowledged　as　the　first　and　original。　This　propensity　to　make　ourselves　in　the　subjective　determining　principles　of　our　choice　serve　as　the　objective　determining　principle　of　the　will　generally　may　be　called　self…love；　and　if　this　pretends　to　be　legislative　as　an
