In this monograph Mr Nathan presents a contemporary examination of the concept. He analyses the meaning of the word 'just' and critically reviews principles of justice to which men actually adhere or which they could conceivably propose. The author's intention is not to preach a particular morality, much less to advocate a certain set of legal reforms. It is to clarify what men are doing when they think or speak in terms ofj ustice and to show what can and what cannot logically be said in such terms. University of Exeter W. D.

Introduction 1 'Just' has a lot of senses; and a formula like 'unjust actions are always wrong' can express as many different moral beliefs as there are different senses of 'just'. But even if we fix on one particular sense of'just', there is a multiplicity ofways in which the value of an action can be held to depend on whether or not it is just in that sense, or on the degree of justice or injustice, in that sense, which can be attributed to it. 'Unjust actions are always wrong' expresses only one of these ways. For someone might hold, not that all actions are wrong or impermissible which are in some particular sense unjust, but that, for instance, only those actions are impermissible which are unjust to a cer tain degree, or that actions are impermissible if and only if they are both unjust and impermissible by utilitarian standards. And this is to say nothing about the different ways in which the obligatoriness of an action could be held to depend on whether or not or how just it is. Any belief which makes the value of actions depend in any way on whether or not they can be called just, or on how just or unjust they are, in any particular sense of'just', I call a principle ofjustice: there are many more different conceivable principles of justice than there are even different senses of 'just'. My first aim in this essay is to describe the range of senses of 'just', and the even wider range of conceivable principles of justice. And my other aims are to say something about the logical and psychological factors which affect the relative popularity of these various principles and about the political implications of one or two of the more popular. It might seem as though the meaning of'just' is so vague that this programme could only amount to the description and application of every conceivable moral principle whatsoever. But we shall see that the senses of 'just' are such that principles of justice are invariably determinate moral beliefs, whose implications can be very different from those of moral beliefs
