former　violate　strict　or　rigorous　（inflexible）　duty；　the　latter　only

laxer　（meritorious）　duty。　Thus　it　has　been　completely　shown　how　all

duties　depend　as　regards　the　nature　of　the　obligation　（not　the

object　of　the　action）　on　the　same　principle。

　　If　now　we　attend　to　ourselves　on　occasion　of　any　transgression　of

duty；　we　shall　find　that　we　in　fact　do　not　will　that　our　maxim

should　be　a　universal　law；　for　that　is　impossible　for　us；　on　the

contrary；　we　will　that　the　opposite　should　remain　a　universal　law；

only　we　assume　the　liberty　of　making　an　exception　in　our　own　favour　or

（just　for　this　time　only）　in　favour　of　our　inclination。　Consequently

if　we　considered　all　cases　from　one　and　the　same　point　of　view；

namely；　that　of　reason；　we　should　find　a　contradiction　in　our　own

will；　namely；　that　a　certain　principle　should　be　objectively　necessary

as　a　universal　law；　and　yet　subjectively　should　not　be　universal；

but　admit　of　exceptions。　As　however　we　at　one　moment　regard　our　action

from　the　point　of　view　of　a　will　wholly　conformed　to　reason；　and

then　again　look　at　the　same　action　from　the　point　of　view　of　a　will

affected　by　inclination；　there　is　not　really　any　contradiction；　but　an

antagonism　of　inclination　to　the　precept　of　reason；　whereby　the

universality　of　the　principle　is　changed　into　a　mere　generality；　so

that　the　practical　principle　of　reason　shall　meet　the　maxim　half

way。　Now；　although　this　cannot　be　justified　in　our　own　impartial

judgement；　yet　it　proves　that　we　do　really　recognise　the　validity　of

the　categorical　imperative　and　（with　all　respect　for　it）　only　allow

ourselves　a　few　exceptions；　which　we　think　unimportant　and　forced　from

us。

　　We　have　thus　established　at　least　this　much；　that　if　duty　is　a

conception　which　is　to　have　any　import　and　real　legislative

authority　for　our　actions；　it　can　only　be　expressed　in　categorical　and

not　at　all　in　hypothetical　imperatives。　We　have　also；　which　is　of

great　importance；　exhibited　clearly　and　definitely　for　every　practical

application　the　content　of　the　categorical　imperative；　which　must

contain　the　principle　of　all　duty　if　there　is　such　a　thing　at　all。

We　have　not　yet；　however；　advanced　so　far　as　to　prove　a　priori　that

there　actually　is　such　an　imperative；　that　there　is　a　practical　law

which　commands　absolutely　of　itself　and　without　any　other　impulse；　and

that　the　following　of　this　law　is　duty。

　　With　the　view　of　attaining　to　this；　it　is　of　extreme　importance　to

remember　that　we　must　not　allow　ourselves　to　think　of　deducing　the

reality　of　this　principle　from　the　particular　attributes　of　human

nature。　For　duty　is　to　be　a　practical；　unconditional　necessity　of

action；　it　must　therefore　hold　for　all　rational　beings　（to　whom　an

imperative　can　apply　at　all）；　and　for　this　reason　only　be　also　a　law

for　all　human　wills。　On　the　contrary；　whatever　is　deduced　from　the

particular　natural　characteristics　of　humanity；　from　certain

feelings　and　propensions；　nay；　even；　if　possible；　from　any

particular　tendency　proper　to　human　reason；　and　which　need　not

necessarily　hold　for　the　will　of　every　rational　being；　this　may　indeed

supply　us　with　a　maxim；　but　not　with　a　law；　with　a　subjective

principle　on　which　we　may　have　a　propension　and　inclination　to　act；

but　not　with　an　objective　principle　on　which　we　should　be　enjoined

to　act；　even　though　all　our　propensions；　inclinations；　and　natural

dispositions　were　opposed　to　it。　In　fact；　the　sublimity　and

intrinsic　dignity　of　the　command　in　duty　are　so　much　the　more　evident；

the　less　the　subjective　impulses　favour　it　and　the　more　they　oppose

it；　without　being　able　in　the　slightest　degree　to　weaken　the

obligation　of　the　law　or　to　diminish　its　validity。

　　Here　then　we　see　philosophy　brought　to　a　critical　position；　since　it

has　to　be　firmly　fixed；　notwithstanding　that　it　has　nothing　to　support

it　in　heaven　or　earth。　Here　it　must　show　its　purity　as　absolute

director　of　its　own　laws；　not　the　herald　of　those　which　are

whispered　to　it　by　an　implanted　sense　or　who　knows　what　tutelary

nature。　Although　these　may　be　better　than　nothing；　yet　they　can

never　afford　principles　dictated　by　reason；　which　must　have　their

source　wholly　a　priori　and　thence　their　commanding　authority；

expecting　everything　from　the　supremacy　of　the　law　and　the　due　respect

for　it；　nothing　from　inclination；　or　else　condemning　the　man　to

self…contempt　and　inward　abhorrence。

　　Thus　every　empirical　element　is　not　only　quite　incapable　of　being　an

aid　to　the　principle　of　morality；　but　is　even　highly　prejudicial　to

the　purity　of　morals；　for　the　proper　and　inestimable　worth　of　an

absolutely　good　will　consists　just　in　this；　that　the　principle　of

action　is　free　from　all　influence　of　contingent　grounds；　which　alone

experience　can　furnish。　We　cannot　too　much　or　too　often　repeat　our

warning　against　this　lax　and　even　mean　habit　of　thought　which　seeks

for　its　principle　amongst　empirical　motives　and　laws；　for　human　reason

in　its　weariness　is　glad　to　rest　on　this　pillow；　and　in　a　dream　of

sweet　illusions　（in　which；　instead　of　Juno；　it　embraces　a　cloud）　it

substitutes　for　morality　a　bastard　patched　up　from　limbs　of　various

derivation；　which　looks　like　anything　one　chooses　to　see　in　it；　only

not　like　virtue　to　one　who　has　once　beheld　her　in　her　true　form。*



　　*To　behold　virtue　in　her　proper　form　is　nothing　else　but　to

contemplate　morality　stripped　of　all　admixture　of　sensible　things

and　of　every　spurious　ornament　of　reward　or　self…love。　How　much　she

then　eclipses　everything　else　that　appears　charming　to　the　affections；

every　one　may　readily　perceive　with　the　least　exertion　of　his

reason；　if　it　be　not　wholly　spoiled　for　abstraction。



　　The　question　then　is　this：　〃Is　it　a　necessary　law　for　all　rational

beings　that　they　should　always　judge　of　their　actions　by　maxims　of

which　they　can　themselves　will　that　they　should　serve　as　universal

laws？〃　If　it　is　so；　then　it　must　be　connected　（altogether　a　priori）

with　the　very　conception　of　the　will　of　a　rational　being　generally。

But　in　order　to　discover　this　connexion　we　must；　however

reluctantly；　take　a　step　into　metaphysic；　although　into　a　domain　of　it

which　is　distinct　from　speculative　philosophy；　namely；　the

metaphysic　of　morals。　In　a　practical　philosophy；　where　it　is　not　the

reasons　of　what　happens　that　we　have　to　ascertain；　but　the　laws　of

what　ought　to　happen；　even　although　it　never　does；　i。e。；　objective

practical　laws；　there　it　is　not　necessary　to　inquire　into　the

reasons　why　anything　pleases　or　displeases；　how　the　pleasure　of　mere

sensation　differs　from　taste；　and　whether　the　latter　is　distinct

from　a　general　satisfaction　of　reason；　on　what　the　feeling　of　pleasure

or　pain　rests；　and　how　from　it　desires　and　inclinations　arise；　and

from　these　again　maxims　by　the　co…operation　of　reason：　for　all　this

belongs　to　an　empirical　psychology；　which　would　constitute　the

second　part　of　physics；　if　we　regard　physics　as　the　philosophy　of

nature；　so　far　as　it　is　based　on　empirical　laws。　But　here　we　are

concerned　with　objective　practical　laws　and；　consequently；　with　the

relation　of　the　will　to　itself　so　far　as　it　is　determined　by　reason

alone；　in　which　case　whatever　has　reference　to　anything　empirical　is

necessarily　excluded；　since　if　reason　of　itself　alone　determines　the

conduct　（and　it　is　the　possibility　of　this　that　we　are　now

investigating）；　it　must　necessarily　do　so　a　priori。

　　The　will　is　conceived　as　a　faculty　of　determining　oneself　to

action　in　accordance　with　the　conception　of　certain　laws。　And　such　a

faculty　can　be　found　only　in　rational　beings。　Now　that　which　serves

the　will　as　the　objective　ground　of　its　self…determination　is　the　end；

and；　if　this　is　assigned　by　reason　alone；　it　must　hold　for　all

rational　beings。　On　the　other　hand；　that　which　merely　contains　the

ground　of　possibility　of　the　action　of　which　the　effect　is　the　end；

this　is　called　the　means。　The　subjective　ground　of　the　desire　is　the

spring；　the　objective　ground　of　th
