      Kant
      ==== 
 
 "* Sapere Aude! *  Dare to use your own intelligence!  This is the 
 maxim of the Enlightenment!"  [From 'Was ist Aufklarung?' (What is 
 Enlightenment?) -- Immanuel Kant].
 
 "Interestingly,  Kant (1724-1804) acknowledged that he had despised 
 the ignorant masses until he read Rousseau and came to appreciate the 
 worth that exists in every human being. For other reasons too, Kant 
 is part of the tradition deriving from both Spinoza and Rousseau. 
 Like his predecessors, Kant insisted that actions resulting from 
 desires cannot be free.
 
 Freedom is to be found only in rational action. Moreover, whatever is 
 demanded by reason must be demanded of all rational beings; hence, 
 rational action cannot be based on a single individual's personal 
 desires, but must be action in accordance with something that he can 
 will to be a universal law. This view roughly parallels Rousseau's 
 idea of the general will as that which, as opposed to the individual 
 will, a person shares with the whole community. Kant extended this 
 community to all rational beings.
 
 Kant's most distinctive contribution to ethics was his insistence 
 that our actions possess moral worth only when we do our duty for 
 its own sake. He first introduced this idea as something accepted by 
 our common moral consciousness and only then tried to show that it is 
 an essential element of any rational morality. In claiming that this 
 idea is central to the common moral consciousness, Kant was 
 expressing in heightened form a tendency of Judeo-Christian ethics 
 and revealing how much the Western ethical consciousness had changed 
 since the time of Socrates, Plato, and Aristotle.
 
 Does our common moral consciousness really insist that there is no 
 moral worth in any action done for any motive other than duty? 
 Certainly we would be less inclined to praise the young man who 
 plunges into the surf to rescue a drowning child if we learned that 
 he did it because he expected a handsome reward from the child's 
 millionaire father. This feeling lies behind Kant's disagreement with 
 all those moral philosophers who have argued that we should do what 
 is right because that is the path to happiness, either on earth or in 
 heaven. 
 
 But Kant went further than this. He was equally opposed to those who 
 see benevolent or sympathetic feelings as the basis of morality. Here 
 he may be reflecting the moral consciousness of 18th-century 
 Protestant Germany, but it appears that even then the moral 
 consciousness of Britain, as reflected in the writings of 
 Shaftesbury, Hutcheson, Butler, and Hume, was very different. The 
 moral consciousness of Western civilization in the last quarter of 
 the 20th century also appears to be different from the one Kant was 
 describing.
 
 Kant's ethics is based on his distinction between  hypothetical and 
 categorical imperatives. He called any action based on  desires a 
 hypothetical imperative, meaning by this that it is a command of 
 reason that applies only if we desire the goal. For example, "Be 
 honest, so that people will think well of you!" is an imperative that 
 applies only if you want people to think well of you. A similarly 
 hypothetical analysis can be given of the imperatives suggested by, 
 say, Shaftesbury's ethics: "Help those in distress, if you sympathize 
 with their sufferings!" 
 
 In contrast to such approaches to ethics, Kant said that the commands 
 of morality must be categorical imperatives: they must apply to all 
 rational beings, regardless of their wants and feelings. To most 
 philosophers this poses an insuperable problem: a moral law that 
 applied to all rational beings, irrespective of their personal wants 
 and desires, could have no specific goals or aims because all such 
 aims would have to be based on someone's wants or desires.
 
 It took Kant's peculiar genius to seize upon precisely this 
 implication, which to others would have refuted his claims, and to 
 use it to derive the nature of the moral law. Because nothing else 
 but reason is left to determine the content of the moral law, the 
 only form this law can take is the universal principle of reason. 
 Thus the supreme formal principle of Kant's ethics is: "Act only on 
 that maxim through which you can at the same time will that it should 
 become a universal law."
 
 Kant still faced two major problems. First, he had to explain how we 
 can be moved by reason alone to act in accordance with this supreme 
 moral law; and, second, he had to show that this principle is able to 
 provide practical guidance in our choices. If we were to couple 
 Hume's theory that reason is always the slave of the passions with 
 Kant's denial of moral worth to all actions motivated by desires, the 
 outcome would be that no actions can have moral worth. 
 
 To avoid such moral skepticism, Kant maintained that reason alone can 
 lead to action. Unfortunately he was unable to say much in defense of 
 this claim. Of course, the mere fact that we otherwise face so 
 unpalatable a conclusion is in itself a powerful incentive to believe 
 that somehow a categorical imperative must be possible, but this is 
 not convincing to anyone not already wedded to Kant's view of moral 
 worth. 
 
 At one point Kant appeared to be taking a different line. He wrote 
 that the moral law inevitably produces in us a feeling of reverence 
 or awe. If he meant to say that this feeling then becomes the 
 motivation for obedience, however, he was conceding Hume's point that 
 reason alone is powerless to bring about action. It would also be 
 difficult to accept that anything, even the moral law, can 
 necessarily produce a certain kind of feeling in all rational beings 
 regardless of their psychological constitution. Thus this approach 
 does not succeed in clarifying Kant's position or rendering it 
 plausible.
 
 Kant gave closer attention to the problem of how his supreme formal 
 principle of morality can provide guidance in concrete situations. 
 One of his examples is as follows. Suppose that I plan to get some 
 money by promising to pay it back, although I have no intention of 
 keeping my promise. The maxim of such an action might be "Make false 
 promises when it suits you to do so." Could such a maxim be a 
 universal law? Of course not. If promises were so easily broken, no 
 one would rely on them, and the practice of promising would cease. 
 For this reason, I know that the moral law does not allow me to carry 
 out my plan.
 
 Not all situations are so easily decided. Another of Kant's examples 
 deals with aiding those in distress. I see someone in distress, whom 
 I could easily help, but I prefer not to do so. Can I will as a 
 universal law the maxim that a person should refuse assistance to 
 those in distress? Unlike the case of promising, there is no strict 
 inconsistency in this maxim being a universal law. 
 
 Kant, however, says that I cannot will it to be such because I may 
 someday be in distress myself, and I would then want assistance from 
 others. This type of example is less convincing than the previous 
 one. If I value self-sufficiency so highly that I would rather remain 
 in distress than escape from it through the intervention of another, 
 Kant's principle no longer tells me that I have a duty to assist 
 those in distress. 
 
 In effect, Kant's supreme principle of practical reason can only tell 
 us what to do in those special cases in which turning the maxim of 
 our action into a universal law yields a contradiction. Outside this 
 limited range, the moral law that was to apply to all rational beings 
 regardless of their wants and desires cannot guide us except by 
 appealing to our desires.
 
 Kant does offer alternative formulations of the categorical 
 imperative, and one of these has been seen as providing more 
 substantial guidance than the formulation so far considered. This 
 formulation is: "So act that you treat humanity in your own person 
 and in the person of everyone else always at the same time as an end 
 and never merely as means." 
 
 The connection between this formulation and the first one is not 
 entirely clear, but the idea seems to be that when I choose for 
 myself I treat myself as an end. If, therefore, in accordance with 
 the principle of universal law, I must choose so that all could 
 choose similarly, I must respect everyone else as an end. Even if 
 this is valid, the application of the principle raises further 
 questions. 
 
 What is it to treat someone merely as a means? Using a person as a  
 slave is an obvious example; Kant, like Bentham, was making a stand 
 against this kind of inequality while it still flourished as an 
 institution in some parts of the world. But to condemn slavery we 
 have only to give equal weight to the interests of the slaves. Does 
 Kant's principle take us any further than Utilitarianism? Modern 
 Kantians hold that it does because they interpret it as denying the 
 legitimacy of sacrificing the rights of one human being in order to 
 benefit others.
 
 One thing that can be said confidently is that Kant was firmly 
 opposed to the Utilitarian principle of judging every action by its 
 consequences. His ethics is a deontology. In other words, the 
 rightness of an action depends on whether it accords with a rule 
 irrespective of its consequences. In one essay Kant went so far as to 
 say that it would be wrong to tell a lie even to a would-be murderer 
 who came to your door seeking to kill an innocent person hidden in 
 your house. 
 
 This kind of situation illustrates how difficult it is to remain a 
 strict deontologist when principles may clash. Apparently Kant 
 believed that his principle of universal law required that one never 
 tell lies, but it could also be argued that his principle of treating 
 everyone as an end would necessitate doing everything possible to 
 save the life of an innocent person. Another possibility would be to 
 formulate the maxim of the action with sufficient precision to define 
 the circumstances under which it would be permissible to tell 
 lies--e.g., we could all agree to a universal law that permitted lies 
 to people intending to commit murder. 
 
 Kant did not explore such solutions."
