He considers it "not primarily as a question about the relation between the individual and society, but in essence and origin as a question about each individual's relation to himself". The fundamental problem is the conflict within each individual between two standpoints, the personal and the impersonal. According to Nagel, human beings can occupy two different points of view. On the one hand, we can see thing from where we are, with that I we happen to be as the center of perception. In doing so, we are viewing the world from a personal standpoint, which gives rise to a partial and individualistic concern for oneself. From this standpoint, we concentrate mainly on our personal interests, and the further the others are related to us, the less their interests to us. On the other hand we are also "able to think about the world in abstraction from our particular position in it" . We can ignore, from the description of the situation, the fact that a particular standpoint is our own. We then view from the impersonal standpoint, from which I am just one among the many, and the situation is taken impartially. The fact that we can occupy both the personal and impersonal standpoints gives rise to the unsolved problem in political philosophy. To Nagel, any plausible and realistic social arrangement should be legitimate. The problem as Nagel says, that .............[t]he impersonal standpoint in each of us produces.... a powerful demand for universal impartiality and equality, while the personal standpoint gives rise to individualistic motives and requirements which present obstacles to the pursuit and realization of such ideal. If a social arrangement cannot adequately reconcile the conflict between the two standpoints, it cannot command the unanimous acceptance from the individuals, and thus will not be legitimate. According to him, if a political ideal merely accommodates to our impersonal standpoint, it would be utopian, i.e. motivationally impossible. The view that our personal interests must be given a more or less equal status as our impartial concern for the society in evaluating a given social arrangement leads Nagel to regard the conflict between the personal and impersonal standpoints of primary importance. However, why must we give so much weight to the individual self-interests when we make a moral assessment of a social arrangement? Is it really as important as claimed by Nagel? This paper is an attempt to find out what should be regarded as the central problem in political philosophy. I shall argue 1. that the conflict between the personal and impersonal standpoints is not important; and 2. that what is important is the conflict within the impersonal standpoint, i.e. the conflict among the different demands from our impartiality. I. The Significance of the Conflict between the Personal and the Impersonal Standpoint A. Two Criteria for the Validity of a Political Ideal In political philosophy, our ultimate aim is to construct and justify a valid political ideal. A political ideal is valid if and only if it is both morally acceptable and practically possible. To be valid, a political ideal must be morally acceptable. We will not rationally accept any political or social arrangement which is unjust or immoral, no matter how efficient it is. A political ideal is morally acceptable if it could not be reasonably rejectecl. Any unreasonable and irrational objection cannot undermine the moral acceptability of a political ideal. Even the fact that most members of a society reject a given social arrangement, simply saying that they do not like it without any further argument, cannot make the arrangement in question less acceptable morally. On the other hand, it must be also practically possible. By practical possibility of a political ideal, I means the possibility that humans, or most of the humans, could lead or could come to lead the form of life ascribed by it through certain feasible process of social and mental development. Essentially, it is expressed in its psychological acceptability. A social arrangement is practically possible only if it is motivationally possible, i.e. it must be derived from at least one of our view points, which can motivate us to accept it. If it is only imposed on us externally, and we have no internal demand for it, we will not have any reasonable, motivational ground to accept it. Nor will it be motivationally possible if the view point from which it is derived has no motivational force on us. A social arrangement which demands the poor people to give all their properties to the rich ones is not practically possible, for it cannot command our motivation to accept it. Although a political theory which is practically impossible cannot be valid and plausible, what should he done in political philosophy is not to show how a social arrangement can be put into practice (e.g. how to make the people accept a certain social arrangement), which is the task of the politicians. For it involves a lot of practical problems which are morally irrelevant to the value and the ethical status of a political theory itself. Rather, the task of a political philosopher is ethical and theoretical, i.e. to justify that a given theory is morally acceptable and practically possible. According to Nagel, a political ideal should be legitimate. A legitimate political ideal is one which reconciles the personal and the impersonal standpoints. It is because, in his view, a political ideal would be practically impossible (though it may be morally acceptable) if it ignores the demand of our personal standpoint. For we would not reasonably accept an arrangement which cannot accommodate to our partial, individualized self-interests. As he says: A fully realized social ideal has to engage the impersonal allegiance of individuals while at the same time permitting their personal motives some free play in the conduct demanded by the system, thus permitting the co-existence and integration of elements in each individual's makeup which are potentially at war with one another. Is it really the case? In examining the view of Nagel, we can first distinguish the following four kinds of political ideals according to their ability to accommodate the demand of our personal and impersonal standpoints: Ideal 1: It can accommodate the demand of both our impersonal and personal standpoints. Ideal 2: It can accommodate the demand of our impersonal standpoint but not that of the personal one. Ideal 3: It can accommodate the demand of our personal standpoint but not that of the impersonal one. Ideal 4: It can accommodate the demand of neither the personal nor the impersonal standpoint. We can now decide which of them is/are valid by appealing to the two criteria of validity, i.e. the moral acceptability and practical possibility. In doing so, we can discover which part of the individual self, i.e. the personal or the impersonal standpoint, or both, is/are necessary in determining the validity of a political ideal. Firstly, Ideal 1 is valid. In satisfying both our impartial claim of the impersonal standpoint and the partial concern for individual self-interests of the personal standpoint, it is both morally acceptable and practically possible. Secondly, Ideal 4 is not valid for it is neither morally acceptable nor practically possible. Failing to accommodate to our impartiality which is the essence of morality, it can be reasonably rejected on the ground that it is not moral. On the other hand, we would not have any motivation to come under it, since none of our standpoints are accommodated by it. Both the validity of Ideal I and the invalidity of Ideal 4 are obvious, for both of the criteria are satisfied and not satisfied respectively. What would happen in conflicting cases, i.e. ones in which only one of the criteria is satisfied? Since both the moral acceptability and the practical possibility are the necessary and sufficient conditions for the validity of a political ideal, the unfulfilment of either of them will denounce the validity of the ideas. Accordingly, Ideal 3 is not valid, for it fails to take up our impersonal standpoint and thus is morally unacceptable. However, is Ideal 2 also invalid by the same reasoning? That is, can we say that its failure to accommodate the personal standpoint entails its failure to command the practical possibility? Nagel will claim that it is, for he regards that the neglect of the demand from the personal standpoint will leave no motivational ground for us to accept it. His view implies that the satisfaction of our partial interests is the sole ground of practical possibility. That is why he assigns so much weight to our personal standpoint that its demand can play a dominant role in accessing the validity of a political ideal. If he is right, only Ideal 1 is valid. It means that unless a political ideal can successfully reconcile our impersonal and personal standpoint, it cannot simultaneously fulfill the two criteria of validity, and thus cannot be valid. This is where the significance of the conflict between the two standpoints in Nagel's theory lies. (待續)  Copyright (c) Hong Kong Society of Humanistic Philosophy. All Rights Reserved.
