I begin by examining the central theses of value pluralism. I then distinguish three different lines of argument that Berlin develops to support his claim that pluralism is not a species of relativism: his commitment to an empirically verifiable version of natural law, his claims about the âhuman horizon,â and his view that some outlooks rest on obvious empirical falsehoods. In analyzing these claims, I argue that Berlinâs invocation of the human horizon is extraneous to the issue at hand and that if pluralists want to reject relativism, they must focus on the minimum content of natural law and the basic needs and interests it highlights, rather than considerations about ânormalâ human behavior or mutual intelligibility. I also highlight some tensions in Berlinâs claim that value pluralism is compatible with a belief in the objectivity of values.
Pluralism
Under the influence of Kant and Collingwood, Berlin held that one of the central purposes of philosophy is to examine the concepts and categories that mediate our experience of the world (CC, 10â11). He agrees with Kant that some of these concepts and categories are âpermanent and unalterableâ but holds that others, most notably the moral and aesthetic, vary a great deal across time and place. Berlin insists that thinking about moral and political concepts in this wayâunearthing the implicit presuppositions of peopleâs ways of making sense of the world and uncovering shifts in these concepts and categoriesâis one of the essential tasks of moral and political philosophy.
This is worth highlighting because Berlinâs work is chiefly concerned with uncovering and examining the most basic presuppositions of the central tradition of Western political theory. As is well known, he claims that these presuppositions have not only distorted our experience in philosophically significant ways but also had harrowing political effects. Berlin diagnoses the central tradition of Western political and moral thought as monistic. Monism approaches ethics and politics rationalistically, holding that the domain of value is, at heart, a âharmonious wholeâ (PIRA, 54). What is meant by this is not immediately apparent, but the basic idea is that although we often talk about different valuesâfreedom, equality, justice, kindness, efficiency, beauty, and so onâmonists hold that these can, in the end, be either reduced to or regulated by a supreme value (e.g., utility) or principle of morality (e.g., the categorical imperative), or combined and realized without remainder in concrete circumstances. In this sense, monism holds that all the different values that constitute âthe all-embracing idea of human societyâ can coexist (PIRA, 54). By thinking in this way, Berlin claims, monists embrace a âjigsaw puzzleâ view, according to which, since it is possible for all genuine values to fit with another, the central task of ethics and politics is merely âto arrange the fragments . . . in the unique way in which they compose the total pattern that is the answer to all our wants and perplexitiesâ (L, 292). On this view, then, conflict and tragedy are not âintrinsic to human lifeâ (CTH, 196).
In theoretical terms, monism thus promises the possibility of rational inquiry uncovering a âtotal answerâ of how human beings should live that solves âall questions, both of theory and of practice, once and for allâ (L, 292). That is, monism offers the possibility of a description of âan ideal universeâa Utopia, if you likeâwhich is simply that described by all true answers to all serious questions,â and, saliently, even if we cannot hope to realize this utopia for practical reasons, it can function as an âideal in terms of which we can measure off our own present imperfectionsâ (RR, 22; see also AC, 68, and CTH, 6).
Rather than seeing value as âone big thingâ (RT, 22), Berlin endorses a position now referred to as âvalue pluralism.â The principal claim of value pluralism is reasonably straightforward: that there are many different values of intrinsic worth. Thus, different values are not merely means toward, or subservient to, more fundamental values or principles in the way that monist views suggest but must be understood in their own terms. Moreover, Berlin continually stresses that values are potentially incompatible and can conflict. Different values often cannot be achieved in concert, even in ideal circumstances, as the pursuit of some values conflicts with the pursuit of others. As Berlin puts it, âneither political equality nor efficient organisation nor social justice is compatible with more than a modicum of individual liberty,â and âjustice and generosity, public and private loyalties, the demands of genius and the claims of society can conflict violently with each otherâ (L, 213). This also suggests, in a way that is less immediately clear, that we can recognize different kinds of value (or, if one prefers, spheres of value), such as the moral, economic, and aesthetic, and that no one subset of values, such as the moral, necessarily trumps other kinds.
Developing these points, followers of Berlin hold that the values and virtues realized in different âstyles of life,â such as those associated with a life of action and a life of contemplation, are incompatible if âthey cannot normally be exemplified in the same life.â3 Consequently, when an individual or group pursues a course of action in order to achieve some end, this often requires them to forgo other ends that a different course of action would realize. The implication is clear: ânot all good things are compatible, still less the ideals of mankindâ (L, 213).
Significantly, Berlin does not merely hold that values can conflict but also stresses that they are often incommensurable. Thus, conflicts between values cannot always be resolved by an uncontroversial rational standard, such as the conclusions of a particular ethical theory or decision procedure, or by agreement on a supreme principle or highest value, such as utility or rights. Put another way, there is no âinfallible measuring rodâ or âsingle universal overarching standardâ (AC, 69â70) that we can appeal to in order to resolve value conflict in every case.4 Thus, Berlinian pluralists deny that any particular value is overriding in the face of value conflict.5
For Berlin, and for those who endorse his claims about the plural nature of value, including Hampshire and Williams, there are many intrinsically valuable ends of human existence and styles of life that individuals can rationally pursue, but these often conflict with each other, with the result that there is no best life or set of ends on which we all have reason to settle.
The plurality and conflict of which Berlin speaks occurs at three levels.6 First, at the level of goods and values. Berlin famously described liberty as having both negative (âHow many doors are open?â) and positive (âWho is master?â) elements that do not cohere but are each ultimate values in their own right (L, 212). Hence, Berlinians insist that values are often âinternally complex and can be inherently pluralistic, containing conflicting elements.â7
Second, pluralism and conflict occur within what Berlin at one point calls a network of values, which he glosses as a âcoherent vision of lifeâ involving âpatterns of behaviour and feeling and disposition and ideals . . . entire structures, entire ways of life, in which the values or ends or motives are interconnected in particular waysâ (A, 207â8).8 (I prefer the term outlook to the more cumbersome network of values and will employ it hereafter.) The point is that every outlook orders different values and ends in a particular way, but because values are multiple, potentially incompatible, and incommensurable, such ordering inevitably constrains the claims of some values in the pursuit of practical congruity. Consider liberalism with its commitment to freedom and equality (and many other values besides). If freedom and equality are intrinsically valuable, potentially conflicting, and incommensurable, then liberals must find a way of living with the tension between the intrinsic claims of these values, rather than imagining that such a tension does not exist or revising their understanding of these values in order to fool themselves into thinking that it does not exist.9
Third, conflict and incommensurability also apply between different outlooks. Outlooks differ according to the goods and values they promote or abhor, as well as by how they rank values. Consequently, distinct outlooks may pursue incommensurably valuable bundles of goods. In his work on Herder and Vico, Berlin stresses the realization that âmore than one equally authentic, equally developed culture was possible, and that such cultures could be widely heterogeneous, could, indeed, be incompatible and incommensurable.â This in turn entails a âgenuine pluralism, and an explicit refutation of the belief that man everywhere, at all times, possessed an identical nature which, in its quest for self-fulfillment, sought after the same endsâ (TCE, 164; for further statements, see TCE, 168, 176â77, and AC, 12). Subsequently, Berlin claims that the concept of an ideal state is incoherent: because realizing some values necessarily involves the forgoing or sacrificing of others, âthe notion of total human fulfilment is a formal contradiction, a metaphysical chimeraâ (L, 213). This is one of the reasons why, for Berlin, tragedy is intrinsic to human life (CTH, 203). Significantly, this suggests that it is futile to grade different outlooks according to a transhistorical or perennial vision of how different values must coalesce (CTH, 68). Just as there is no one best life for man, there is no ideal form of society; in terms of value, each cultural, political, moral, and religious way of life has its own distinctive advantages and costs.
This points to a further element of Berlinâs thought that readers and critics alike tend to overlook, or at least downplay, that I refer to as the mutual dependence condition. The basic idea is that historical and philosophical reflection reveals that the valuable elements of different outlooks cannot be freely combined and that it is often the case that the different constitutive features of an outlook are inexorably intertwined. As a crude example, we cannot isolate a favorable attitude toward samurai bravery from unfavorable attitudes toward tsujigiri, strict honor codes, and the hierarchical social relations that underpinned the samurai way of life.
According to the mutual dependence condition, the objectionable features of an outlook may be indispensable presuppositions of those features we praise. Pluralists who share Berlinâs historical sensibility therefore stress that value is often not independent of disvalue, that virtue often coexists with vice, and that in many outlooks the bad may be a condition of the good. Consequently, they claim that life is tragic not only because values often conflict and are incommensurable, with the result that we cannot hope to achieve all good things at once, but also because justice, virtue, and value may be dependent on injustice, vice, and disvalue.10
As Stuart Hampshire notes, this historically informed style of thinking understands that such outlooksâwhich Hampshire calls ways of lifeâare âtotalities of customs, attitudes, beliefs, institutions, which are interconnected and mutually dependent in patterns that are sometimes evident and sometimes subtle and concealed. One cannot easily abstract the activity or practice from its setting in a complete way of life, and make one-to-one comparisons between activities and practices which are part of different ways of lifeâ (MC, 6). To this end, Hampshire endorses what he refers to as the âno-shopping principleâ: the claim that we cannot âpick and chooseâ aspects or elements of one outlook and combine them with aspects or elements of another outlook because the coherence of outlooks âcomes from their distinct historiesâ (MC, 148). Value pluralists who endorse this consequently hold that trying to amalgamate the admirable features of different outlooks is an error because it is likely to be the case that they cannot, as a matter of empirical realism, be combined while retaining their vitality (AC, 124).11 In some cases, the very attempt to do so can have terrifying political results.12
This way of thinking about value therefore repudiates a (pseudo-Hegelian) view of historical progress that holds that ânothing that is of permanent value need be lost irretrievably, for in some form it is preserved in the next higher stageâ (AC, 123). Berlin insists that when some historical changes occur, âgains in one respect necessarily entail losses in another,â and that, as a result, âsome valuable forms of experience are doomed to disappearance, not always to be replaced by something necessarily more valuable than themselvesâ (AC, 123â24). Consider the distinction Berlin makes in his essay on Machiavelli between pagan morality and Christian morality. One does not have to be a full-blooded Nietzschean to believe that while the move from the former to the latter brings with it significant gains and benefits, it also imposes equally real losses to the values of pagan moralityââcourage, vigour, fortitude and adversity, public achievement, order, disciplineâ (AC, 45).
