First published in 1903, this volume revolutionized philosophy and forever altered the direction of ethical studies. A philosopher’s philosopher, G. E. Moore was the idol of the Bloomsbury group, and Lytton Strachey declared that Principia Ethica marked the rebirth of the Age of Reason. This work clarifies some of moral philosophy’s most common confusions and redefines the science’s terminology. Six chapters explore: the subject matter of ethics, naturalistic ethics, hedonism, metaphysical ethics, ethics in relation to conduct, and the ideal. Moore's (...) simplicity of style and precise use of everyday language exercised an enormous influence on the development of analytic philosophy, and they contribute to the continuing resonance of his compelling arguments.

Abstract: The paper provides a general account of value relations. It takes its departure in a special type of value relation, parity, which according to Ruth Chang is a form of evaluative comparability that differs from the three standard forms of comparability: betterness, worseness and equal goodness. Recently, Joshua Gert has suggested that the notion of parity can be accounted for if value comparisons are interpreted as normative assessments of preference. While Gert's basic idea is attractive, the way he develops (...) it is flawed: His modeling of values by intervals of permissible preference strengths is inadequate. Instead, I provide an alternative modeling in terms of intersections of rationally permissible preference orderings. This yields a general taxonomy of all binary value relations. The paper concludes with some implications of this approach for rational choice. (shrink)

The main point of this paper has been to show that the concept of evaluative incompleteness deserves consideration. In addition, I have suggested that it is plausible to accept that certain states of affairs in fact are evaluatively incomplete. But I have not sought to prove that this is so; indeed, I do not know how such proof might be given. Just which states of affairs, if any, are evaluatively incomplete is an extremely vexed question, and it is not one (...) to which I have attempted to supply any systematic answer. My aim has been merely to point out that it is arguable that certain states of affairs are evaluatively incomplete — a fact that ought not to be overlooked due to an unquestioning acceptance of (II) and a fact which, certainly, ought not to be ruled out by fiat due to an adherence to definitions and assumptions which imply that (II) is false.

In this paper I examine what I will call "the standard account" of intrinsic value as it appears in recent textbooks written by John Hospers, William Frankena, and Richard B. Brandt. I argue: (a) it is not clear whether a theory of intrinsic value can be developed along the lines of the standard account; (b) if one is to develop such a theory, one will need to introduce a notion of "basic intrinsic value" in addition to the notion of "intrinsic (...) value"; and (c) several different theories of intrinsic value may account for the same judgments concerning desirability, and it will be arbitrary to choose one of these theories over another.

Situationist deontic logic is a model of that fraction of normative discourse which refers to only one situation and one set of alternatives. As we can see from a whole series of well-known paradoxes, standard deontic logic (SDL) is seriously mistaken even at the situationist level. In this paper it is shown how a more realistic deontic logic can be based on the assumption that prescriptive predicates satisfy the property of contranegativity. A satisfactory account of situation-specific norms is a necessary (...) prerequisite for a successful treatment of more complex normative structures. (shrink)

In this paper, I argue against defining either of ‘good’ and ‘better’ in terms of the other. According to definitions of ‘good’ in terms of ‘better’, something is good if and only if it is better than some indifference point. Against this approach, I argue that the indifference point cannot be defined in terms of ‘better’ without ruling out some reasonable axiologies. Against defining ‘better’ in terms of ‘good’, I argue that this approach either cannot allow for the incorruptibility of (...) intrinsic goodness or it breaks down in cases where both of the relata of ‘better’ are bad.

Joshua Gert and Wlodek Rabinowicz have developed frameworks for value relations that are rich enough to allow for non-standard value relations such as parity. Yet their frameworks do not allow for any non-standard preference relations. In this paper, I shall defend a symmetry between values and preferences, namely, that for every value relation, there is a corresponding preference relation, and vice versa. I claim that if the arguments that there are non-standard value relations are cogent, these arguments, mutatis mutandis, also (...) show that there are non-standard preference relations. Hence frameworks of Gert and Rabinowicz's type are either inadequate since there are cogent arguments for both non-standard value and preference relations and these frameworks deny this, or they lack support since the arguments for non-standard value relations are unconvincing. Instead, I propose a simpler framework that allows for both non-standard value and preference relations. (shrink)

Some things have positive value and some things have negative value. The things with positive value are good and the things with negative value are bad. There are also things in-between that are neither good nor bad, which are neutral. All in all, then, there are three monadic value predicates: “good,” “bad,” and “neutral.”.

The basic theory of preference relations contains a trivial part reflected by axioms A1 and A2, which say that preference relations are preorders. The next step is to find other axims which carry the theory beyond the level of the trivial. This paper is to a great part a critical survey of such suggested axioms. The results are much in the negative — many proposed axioms imply too strange theorems to be acceptable as axioms in a general theory of preference. (...) This does not exclude, of course, that they may well be reasonable axioms for special calculi of preference. I believe that many axioms which are rejected here may be plausible if their range of application is restricted by conditions which are possible to formulate only in a language richer than that of the propositional calculus, e.g. in one containing modal operators or probabilistic concepts.
