DUTY FOR DUTY SAKE IN KANTIAN ETHICS: Juvenal Sibomana


1. INTRODUCTION
Kant’s project in the Groundwork is “the search for and establishment of the supreme principle of morality”[1] The establishment of moral principles and moral laws culminated in formulations of the categorical imperative which is the form of all properly moral principles. This categorical imperative arise from reason. It is the universal and supreme principle of morality which admits  of no conditions or exceptions because there is nothing higher by reference to which conditions or exceptions could be justified. For Kant there is a single moral obligation, which he called the "categorical imperative", and it is derived from the concept of duty. Duty comes in as the practice of this categorical imperative. In fact, in Kant’s theory, the fundamental moral law is the categorical imperative and remains the ground of ethical duties.
For Kant, duty is a necessity to act from an obligation. And that necessity needs to be objective and universal in order to have moral value and has no need to refer to any Supreme Being except autonomy and good will grounded on pure reason. Kant writes : “ A will whose maxims necessarily accord with the laws of autonomy is a holy, or absolute good, will. The dependence of the will not absolutely good on the principle of autonomy (that is, moral necessitation) is obligation. Obligation can thus have no reference to a holy being. The objective necessity to act from obligation is called duty.[2]
For Kant, an action fulfilling an ethical duty has greater moral  merit if it is performed from duty, but the incentive from which we perform a right action makes no difference to its juridical rightness. Under human conditions, where we have to struggle against unruly impulses, inclinations and desires, a good will is manifested in acting  for the sake of duty.  In this paper, I will  study this concept of duty in Kantian ethics, its motives, its meanings, its grounds in link with his philosophical thought in general. I will demonstrate the originality of the concept “duty” and show that Kant “provided a very different account of ordinary moral reasoning,[3] for the performance of juridical duties may be externally coerced, but Kant’s basic conception of ethical or moral duty is inner or self-constraint. Duties are ends in themselves. These ends based on the categorical imperative, are exceedingly important to the structure of Kantian morality. For Kant, all ethical duties are grounded on ends that is why his theory of ethical duties is entirely teleological.
2. KANTIAN’S CONCEPT OF DUTY
Why is duty is an odious word?  Asked one of Kantian scholars Allen wood.  According to him, “ ‘Duty’ is not  only a crucial concept in Kant’s ethics but also in effect a technical term in Kantian vocabulary.”[4] Whatever affinity the Kantian sense of ‘duty’ may have with the ordinary  meaning of the word in English (or of Pflicht in German), must depend on our  putting some distance between the technical Kantian meaning of his word    “duty” and the sense of the term as it is used commonly.
In general understanding, “duty is what a person is obligated or required to do. Duties can be moral, legal, parental, occupational, professional, etc., all depending  on their foundations or grounds. Because a duty can have several grounds,  it can be, say, both moral and legal, though it need not be of more than one type.”[5]  In this sense, duties are often what we have in consequence of some role we play in a social institution, arrangement, or relationship.
The danger of this common understanding of duty is that people therefore appeal to duty when they want to put an end to  critical reflection  about what we are doing. Soldiers are supposed to think of their duty to their  unit, to their commanders, to their “mission”, to their country, to their flag and nothing else. This understanding of duty makes them fearless and killing machines without guilt consciousness.  Kantian theory and understanding of “duty” will give answer to such dilemma and show that it is a new technical concept.
For Kant, duty has a strong link with good will. In his explanations, “duty” refers  to the act of freely making oneself to desire something and do it because he appreciates moral reasons  there are for doing it. Therefore, “to do something from duty means: to obey reason.” Obedience  here signifies neither external authority nor coercion but only that the reasons are moral reasons, as distinct from merely instrumental or prudential reasons. Acting from duty do not obey any law except one of good will or self-constraint to respect moral law. “Kant gives the name “duty” to all actions we have moral reasons to do, even meritorious  actions that are not morally blamable to omit, because (human nature being what it is), we will occasionally need to exercise inner rational constraint if we are to perform these morally valuable actions.”[6]

3. THE MOTIVES OF DUTY
A human action is morally good, not because it is done from immediate inclination,  or from self-interest, but because it is done for the sake of duty. Thus the motive of duty includes all the properly moral reasons we have to perform morally valuable actions. Kant distinguishes two essentials elements that can motivate our actions. As far as the realizations of our duties are concerned, Kant suggest that we should act from duty (aus Pflicht) instead of acting for the sake of duty (Pflichtmässig).
3.1. Acting from Duty: Perfect Duties
In the beginning of the second section of Groundwork, Kant says that the only thing in this world or outside of it that is good without limitations is the good will. He stipulates that acting from duty is a supreme value of morality and the only motive of moral law because it has his source from reason or self-legislation: “Thus morality lies in the relation of our actions to the autonomy of the will−that is to a possible making of universal law by means of its maxims. An action which is compatible with the autonomy of the will is permitted; one which does not harmonize with it is forbidden.”[7]
What does Kant mean by “acting from duty”? I said above already that the concept “duty” it self is technical, confusing and perilous enough. We saw that “duty is the necessity  of an action from the respect for the law” and that the term “law” refers to any practical principle of reason that is objectively and universally valid for all rational beings and it has to be necessary. This necessity refers to what Kant calls “Practical necessitation” and means what is constraint.  This constraint or obligation does not refer to external constraint or coercion, as by chains, prison, prison walls, or threats, but rather the inner rational self-constraint that one exercises over oneself from respect for correct principles. As Allen Wood would summarize it, “To act from duty, in short, is to do something because you know that an objectively valid moral principle demands it, so that gives you a good reason for deciding to do it, and then making yourself do it.”[8]
As we know, Kant is never interested  in the difference between good and bad actions, or between actions worthy of moral and actions unworthy of it. He is much more interested in the intentionality of the moral agent. Self-esteem, honor, good reputation, sympathy or compassion can never be, by themselves source of moral worth. His concern is “what is a authentic, genuine moral worth?”  The answer is that any action has moral worth  when the moral agent acts from duty only. Kant insists that duty is the necessity to act out of reverence for the law. Therefore, Perfect Duties do not allow the leeway in the interest of inclination. They don’t permit one to choose among several possible ways of fulfilling them. Thus, the duty to help those in need is an imperfect duty since it can be fulfilled by helping the sick, the starving, the oppressed, etc. But if one chooses to help the sick, one can choose which  of the sick to help. However, the duty to keep one’s promises and the duty not to harm others are perfect duties since they do not allow one to choose which promises to keep or which people not to harm.[9]



3.2. Acting for the Sake of Duty : Imperfect Duties
For Kant, the first problem of legal duties is conformism. It is necessary to do one’s duty from the motive of duty. “For if any action is to be morally good, it is not enough that it should conform to the moral law, it must also be done for the sake of the moral law: where there is not so, the conformity is only too contingent and precarious, since the non-moral ground at work will now and then produce actions which is in accord with the law, but very often which transgress it.”[10]
            To act for the sake of duty lack moral worth and therefore has some insufficiency. As Kant himself suggested, it is very important to make a difference between to act from duty and to act for the sake of duty.  Not all actions that are  “in conformity with duty” (Pflichtmässig) are “from duty” (aus Plicht). This has to be well understood. According to Kant, some  dutiful good actions, though possible occasions for self-constraint, do not need to be done with self-constraint, because they agree with some of our immediate inclination, empirical desire, or instinct. For such actions,  there is no claim of morality worth because reason, self-constraint and good will are not fully involved in decision making and doing . In other words, we can or should act from duty only and no self-interest reason or empirical inclination is sufficient to motivate us to perform an action. Acting from duty is a pull against our empirical inclinations.
Therefore, only few human actions can belong to the class of moral actions because in order to be logically valid they must be based on pure reason ; and in order to be good, an action must only be performed for the sake of a moral law and not for some other purpose.  I like Kant philosophy because of the rigorism of his moral principles and we can see that there is no room for compromise. Like categorical imperative, duties are principles that are intrinsically valid; they are good ends in themselves, they must be obeyed in all, and by all situations and circumstances. Whenever there is no good will, no self-legislation, no autonomy, therefore no moral worth. It is conformism which create imperfect duties. Imperfect duties are, in Kant’s words, “duties which allow leeway in the interest of inclination,” and  “permit one to choose among several possible ways of fulfilling them.”
4. DUTIES OF VIRTUE
In Kant philosophy, ethical duties are duties of virtue. His ethics are merely “the Doctrine of Virtue” and ethical virtues are “the obligatory ends of pure practical reason”[11]. In the Critique of Practical Reason, Kant describes “virtue” as a naturally acquired faculty of a non-holy will or “the moral disposition in the  struggle. Virtue is characterized  by  “moral strength of a human being’s will in fulfilling his duty. In fact Kant believes that all ends are duties but not virtues. Imperfect or wide duties should guide us in setting the ends of  life: my own perfection and happiness of others. This section will be interesting in the sense that we are going to see when and how our own duties and ends must combine at the same time one’s happiness and perfections of others in order to be morally good. Human beings have the duty to act from duty.
4.1. Duties to Oneself.
In the Western but mainly Anglophone tradition of moral philosophy, the concept of duty to oneself is commonly applied to alleged duties to promote one’s welfare. For Kant, the rational claims of our own happiness rest on prudential reason, not moral reason. Because our own happiness is something we inevitably pursue from prudence without the constraint of duty.[12] Thus, in Kantian Ethics, the concept of a duty to oneself has nothing to do with self interest, self-love, honour, egocentrism or any duty to promote one’s happiness. “My duty towards myself cannot be treated juridically; The law touches only our relations with other men; I have no legal obligations towards myself; and whatever I do to myself I do to a consenting party; I cannot not commit an act of injustice against myself.”[13]
For Kant, human freedom limits moral agent to any thing  which is not rational. Therefore, everything would depend on how and individual determined his own happiness; for our self-regarding duties  would consist in the universal rule to satisfy  all our inclinations in order to further our happiness. This would, however, militate seriously against doing our duties towards others. “in fact, the principle of self-regarding duties is a very different one, which has no connection with our well-being or earthly happiness. Far from ranking  lowest in the scale of precedence, our duties towards ourselves are of primary importance and should have pride of place; for (…) it is obvious that nothing can be expected from a man who dishonours his own person.”[14] Consequently, according to Kant, “The most serious offence against the duty one owes to oneself is suicide.”[15]. For Kant suicide is abominable not because it is forbidden by God or by any religious or civil law. “Suicide is an abomination because it implies  the abuse of man’s freedom of action: He uses freedom to destroy himself. His freedom should be employed to enable him to live as a man.”[16] Duties to ourselves as moral beings  in effect are duties regarding our humanity and our rational capacity to set ends and treat ourselves as ends. And if I can take the example of suicide, a man who commits such crime does not use humanity as end but as a means to fulfill his irrational happiness. Thus, it goes against the principle of autonomy, freedom, and self-legislation.
4.2. Duties towards Others.
For Kant duties towards others are divided into duties of love and duties of respect. This distinction is in accordance with the feeling that accompany their performance, but the content of these duties is to conduct ourselves in a certain ways, not a duty to feel anything.
4. 2. 1. Duties of Love.
According to Kant, duties of love are duties to benefit others (MS 6:450), while duties of respect are duties to avoid humiliating them and enabling them to maintain their self-respect (MS 6:449).[17] Kant further divides the duties of love into duties of beneficence, gratitude and sympathetic participation (Teilnehmung). According to him, we have the duty to place the happiness  of others among our ends, and the wide duty to return benefits to those who have benefited us. Kant thinks that the duty of sympathetic participation is important and above duty of beneficence and gratitude. For this reason he names it “humanity” (Humanität, humanitas practica).  It is important because humanity includes the duty to cultivate the feeling of sympathy in order to strengthen our sensibility to the needs of others and strengthen our capacity to perform duties of beneficence. According to Wood, “The duty of ‘sympathetic participation’ deserves special mention, because the conception itself is perhaps not an obvious one and because appreciating its role in Kantian ethics will help to correct important elements in prevailing false image of Kantian ethics.”[18] Concluding this topic, Kant says that participation, along with love, is also something we all need from other human beings.
4.2.2.  Duties of Respect
For Kant, respecting others requires us to moderate our own self-esteem to allow for proper recognition of the dignity of others. Kant include under the duty not to ‘give scandal’ or to tempt other into the acts for which they will later have reason to reproach themselves. Kantian ethics recognizes only that respect which is grounded in human dignity ( a value that cannot be surpassed or added to), and therefore, it  appraises all human beings  as of equal absolute worth. From  this logic, true merits are shameful and vicious. “Kantian ethics holds that where morality is concerned, we should compare ourselves with the moral law or the idea of virtue, but never with others (VE 27:349, 462, MS 6:435-436). Human achievements have value, but they give the achiever no higher self-worth.”[19] Duties of respect follow the basic principle that all human beings are equal in dignity as ends in themselves.
5. CONCLUSION
Immanuel Kant’s Groundwork of the Metaphysic of Morals  develops the logical foundation for a moral philosophy which is based on a priori rather than empirical principles. Kant’s concern to provide a theory of pure practical reason for moral philosophy is thereby to establish a supreme principle of morality which have universal validity. The moral worth of an act derives from the principle on which the action is performed. The concept of “duty” is the centre of Kantian Ethics. Duty is the necessity to act out of reverence to the law. Kant made a difference between acting from duty and acting for the sake of duty . We saw that only in the second one there is moral worth because it is the motive or the intentionality of an action that determines its moral value. As Dr Chackalackal concludes on Kant’s duty: “Hence the absolute law of reason for Kant is duty itself. The injunction of  the Metaphysic of Morals is clear: “Do your duty from the motive of  duty.”[20] We must  do our duty  for the sake of duty because Reason commands us to do it.  It is a self-constraint act whose motive is the duty itself. The  nature of moral duty and the good will are inseparable and closely related. In order to be moral, any moral agent has to act from duty itself or it is our duty to act from duty with the good will. It would not be a duty to pursue a certain effect of our will, if it were not possible to do so. Kant’s “ought” implies “can”. 
The motive of an action is more important than the consequences of the action, that  is why  the moral value of an action should only be judged by the motives of the action and not by the consequences of the action. The principles of ethical duties go beyond the merely formal principle of duty and they have to do with the matter of choice, namely with ends. Kantian ethics is a system of ends whereby humanity is an absolute end in himself. The foundations of Kantian theory of ethical duties are teleological, and they have to promote certain obligatory ends like perfection or happiness. Therefore, there can be no reliable fulfillment of duty without some degree of virtue because human nature is such that virtue is the fundamental presupposition of all reliable conduct. Kant willingly ignored the human nature to act out of inclinations, desires or feelings. That is why he was criticized of being idealist.
As conclusion, I think that Kant is a rational idealistic moral philosopher who believed in virtue, in the human power of self-legislation, in freedom, in the good will of a being capable of doing duty for the sake of duty itself: “The ultimate destiny of the human race is the greatest moral perfection, provided that it is achieved through human freedom, whereby alone man is capable of the greatest happiness.”[21]

The Autonomy of the will as the sole principles of all Moral laws and Heteronomy of the choice as the opposite in Kantian Ethics

1.1.         Introduction
The most perplexing question concerning about the morality is why should I be moral? According to Kant we be moral for the sake of duty and we experience an unconditional-universal categorical imperative as a command up on us to act morally right, The basic motivation  or reason for moral activity cannot be self-interest or to win over others praise, heteronymous principle like attaining happiness for me or for others, the  will of God and  salvation of the  soul can never serve as the foundation of the morality, since heteronymous principles exist out side of the self they can only be contingently related to us  hence morality cannot derive from materials which is outside of the will because our obligation would be then depend upon something entirely contingent.[1] Kant ground  morality in reason, according to him, morality comprises a set of demands that are unconditionally and universally valid, to support this understanding of moral principles one must show that they originate in reason apriori rather then contingent facts about  human psychology or the circumstance of human life. Kant’s morality follows from the deeper commandments of autonomy which is to extend beyond good and evil and necessarily inescapable since it arises from within the very structure of the self.[2] It is suggested that Kantian morality is ultimately self regarding  and autonomy of the will is  both necessary and  sufficient reason for the morality, it means the moral obligation is not depend on any other claim from out side
 It is difficult to establish or articulate that how Kant tries to establish that moral principles originate in reason. At the same  time Kant insists up on  the importance of establishing moral law in practical reason apriori  and subsequently state that  a conception of practical reason from which he appear to  extract a formulation of the categorical imperatives.  The reasoning is central to the Kantian ethics, it has an over all impact on his moral theory, with which nothing could be substituted or grounded as a valid principles for the moral argument.[3] 

1.      2.  Ground for the practical reason
Our attempts is to drive morality from reason, an independent foundation for morality, definable and aprior, The conception of practical rationality Kant assumes is apriori and has a claim of universal validity, it is the distinguishing features of   Kantian view that it does not attempt to derive morality from a morally neutrals starting point. The authority of the moral conception for us is reasonableness of applying them to ourselves and the motivation to act from it comes ultimately from an understanding of the ideals in question and how they are expressed in the actions which it single out.[4]   
Reason can be related to two fold way, when reason determine the concept, it is the theoretical reason  when it make real it is the practical reason, We are not often act according to impulses and desires, we distinguishes the action  those are in direct conflict with the  duty, if despite of  appearance of various conflicting  principles, we are in agreement of the moral principles shows, there are practical reason at work, the reason can be practical means that what we call the opposition between reason and desire is the very opposition it seems to be.[5] 


Kant attempt to show that irrational and inconsistent qua rational actions, action motivated by desire and inclinations are not sufficient by itself to yield a moral conception. For it is fundamental to his moral view that we recognize different forms of practical reasoning that moral evaluation is distinct from prudential and involves a set of concerns not reducible to some thing more primitive.[6] The hypothetical imperative and the categorical imperative which represent empirically practical reason and pure practical reason are different kinds of normative standards and patterns of critical evaluations, Kant aim is to show that empirically conditioned use of reason does not exhaust the use of reason.

1.3.   The Empirical Reason
The hypothetical imperative is the principle underlying the empirically  conditioned use of reason, it states  that if one wills an end then one ought to will the means needed to achieve it in so far as they are in one’s own power. It assess the rationality of actions relative to the ends which one desires  or has adopted, and thus yield specific judgments about that an individual ought to do only in conjunction with information about her ends.[7]  What makes human reason empirically conditioned is that the affiliation and assessment of action in relative to desired ends. The hypothetical imperative is often thought to apply primarily to the pursuit of one’s own happiness.
Hypotheses supply a principle or ultimate ground for organizing a system of empirical cognitions, hypotheses serves completely to satisfy   my inquiring reason with  respect to them thus a hypotheses  is an assent of the judgment to the truth of a principle on account of the  sufficiency of the  consequences or assent to a supposition as a principle, hypotheses has only a degree of probability greater or lesser in degree, it is a more reasonable opinion or inference of a natural cause to a definitive cause, it cannot be a valid source or ground for the morality.[8] But pure practical reason will address question of evaluation that are  beyond the scope of empirical practical reason, the pure practical reason  will be concerned with the  evaluation and choice of ends for their own sake. This will include the capacity to elect aims and goals viewed as intrinsically good or worthy of choice which can initiate action and structure larger practical pursuit.

2.      1. The Postulate of Practical Reason
Kant is reluctant to admit any external authority as the foundation of the morality, according to him the foundation of the moral law is autonomous self legislating practical reason or will. But he is ready to admit postulates for the morality, Postulate furnishes  a definite rational explanation for the particular belief, a postulate presupposes a belief to be true, a postulate establishes the possibility of following a whole series of rules which we know will achieve the desired result within  the context prescribed, we postulate for example that two parallel line can never intersect even in the infinity.[9] As far as moral postulate are concerned, such assumption are tailored to making the rules of practical living viable. The necessity of a practical postulate therefore has to do with the fact that it is indispensible as a standpoint for moral action. From the practical point of view postulate like God gives an objective reality which cannot be conformed or denied. Moral postulate has their truth value not solely in any theoretical application but in the practical office, they perform in providing a context for action. God is a practical postulate means whenever we behave morally  we must at the same time  think God as real to us in some manner of speaking, thinking God as a real bolster moral action because it validates  the consequential end of such action  the attainment of the highest good. It enables us to be obliged to the moral law.  Kant insist that we cannot reason from God to morality but morality to God.
  The ground of the necessary connection between virtues and happiness is not found in the moral law and yet this law requires us to take the highest good as the object of action, thus  the exigencies of the moral life require  belief in the existence of an intelligent moral God as the author of nature  and harmonizer of natural events moral intentions and the worthiness to be happy.

2.     2.   Kantian Postulate of God
Kant make a shift of attitude  from the dominion of reason to postulates a possible experience of practical realities, he moves away  from speculative knowledge to  beliefs. A postulate of pure practical reason is a theoretical proposition which is not as such demosratable but which is an inseparable corollary of an apriori unconditionally valid practical law, postulates are necessary hypotheses  not a condition for the origination of moral law, practice of law presupposes no possibilities of theoretical knowledge of realities. God the highest original good is the source of the highest derived good the coincidence between morality and happiness. The postulate of God gives consistency, and stability of the moral thought of the Kant.  According to Kant belief in God founded up on moral law, Kant also reaffirms that God can be approached only through practical reason.[10]   
Kant reduce all particular proofs of God existence to ontological, cosmological and physic-theological arguments, Kant demonstrate the influence of reason in this arguments, having been examined other proofs for the existence of God Kant accept the  physic-theological proof as the realm of  practical reason, the idea of God is valuable as much as it is a regulating principles, ordering unity and intelligibility and purpose in the universe.

2.3.   Postulate of Immortality
Another condition to obey the moral law is personal immorality. It is the processes of    gradual  but endless striving for the moral perfections. It belong to the intelligible order, only God can gather up into one intuitive vision the various  phases  of moral striving which constitute the individual ‘s approach to holiness or perfect conformity to the law God and immortality is an essential condition of the persuasion of the moral laws, we need to postulate a future world to an infinitive to perfect the moral order, the purposiveness leads to the concept of  immortality, it is a condition for the supreme good, a complete fitness and endless progress to the purposiveness of human existence, if one is sure that their moral practice would bring fruits in eternal life then there will be a moral perfection and a belief that there would be a flowering of immorality. It is not the moral law require the concept of immortality but it may serve as the incentive to practice moral law, Kant postulate immortality as the necessary condition for the moral law, he open the door of the infinite progresses.  God and immortality is closely connected, practicing the moral law God and immorality are rewarding in the future, these are greatest good or virtue or source of happiness. [11] Kant reduce God and immortality to a mere incentive and reward for the practice of the moral law. Kantian out line of religion within the limits of reason alone is a religious naturalism and rationalism, and various  religious categories are only a colourless and bare rewards for the fulfillment of  moral perfection and  reason.[12]
 



2.4.   Postulate of Freedom
To arrive at the freedom we must being once more with the moral law as the sole fact of practical reason, although it is purely rational and internal  the moral law imposes itself upon our reason somewhat after the matter of fact, since this law proposes an unconditional ought to us it also presupposes a can on the part of the rational agents[13]. The moral law tells us  that whatever the conditions prevailing with the determined series of appearance,  we are unconditionally bound to conform our actions to be free, if it is to be held responsible for acting in accordance with its own concept of the law .
Kantian view of  practical freedom is revisited and revised more then once   for more clarity,  it not clear freedom is only found in the noumenal world or it is found in the empirical world as well, Kant insist that freedom of will is  a necessary  condition for moral law to be valid.[14] Kant also distinguish between  transcendental freedom and practical freedom, transcendental freedom is a special kind of causality conceived metaphysically as the capacity to begin a causal series from itself independently of aprior cause. Practical freedom  is the freedom is ascribe to our self when we think of ourselves as acting especially when we think of our self as moral agent, it involve the capacity to act for reason[15]. Kant distinguishes negative freedom and positive freedom practical freedom is the power to choose willkur that is independent of impulses of sensibility, independent of alien causes determining it, negative freedom is the capacity to act independently of some empirical desire, it is a capacity to deicide for our self how we will satisfy such desires. Kant thinks that practical freedom can be cognized empirically or at least recognized through certain empirical signs, we have capacity to overcome impressions on our sensory faculty of desire by representation of that which useful by presentation of that which is useful or injurious even in a more remote way these consideration also depend on reason.[16] Practical freedom in the positive sense is possession of a causality of a particular kind namely a capacity to follow determinate laws given by the faculty of reason, or the ability of reason to be of itself practical. It amounts to the capacity to recognize rational nature as an ends in itself as a reason for acting in a certain ways and  to act in those ways on the basis of the reason. More generally it involves the capacity to act for reason rather then only on the basis of feeling impulses or desires that might occur independently of reason.[17] 

Conclusion
What pure reason cannot achieve in the speculative order it can bring to pass in the practical. Kant had to restrict knowledge in the strict sense to the field of appearance so that practical faith could be exercised  in regard to thing-in-themselves But critical philosophy still had the responsibility of adhering to its rigorous method of seeking proper foundation  one is under the obligation that contingent choice are to be measured by a standard Though Kantian ethical theory is  based on pure reason he could not bring it is logical conclusion and perfections without postulates of God immorality and freedom, the postulates of God, immortality and freedom are an attempt to bridge between theoretical reason and practical reason, it shows there is a limit to explain and appeal to the reason alone for the moral perfection ,Kant might have been under pressure from the Prussian police who forbade him to publish controversial materials that weaken the traditional orthodox believes in God and immortality and also he might have been under undue pressure from traditional believers to accommodate God in his philosophical system.  Any way Kantian theoretical philosophy has a lots of reference to the God and religions and he indirectly admits that transcendental idea like God and immortality which beyond the grasp of reason is the foundation of the morality. Why should one be moral because reason command us to be moral, it is our duty and ought but also it is an incentive to moral perfection in eternity,  
Kantian postulates give some kind of doubt that whether he was really confidant in presenting reason alone is the strong foundation fro the morality, Kant was a believer he gave sufficient room for the traditional concept to God and immortality  in a round around way but what about a atheist who do not believe any of this postulate how could he achieve  moral perfection, finally we can say that Kant went beyond reason and accepted traditional external authorities like God to establish his moral perfection which reason cannot do because human person is both  rational and intuitive being
