In this paper, we outline a theory of the nature of self-directed agents. What is distinctive about self-directed agents is their ability to anticipate interaction processes and to evaluate their performance, and thus their sensitivity to context. They can improve performance relative to goals, and can, in certain instances, construct new goals. We contrast self-directedness with reactive action processes that are not modifiable by the agent, though they may be modified by supra-agent processes such as populational adaptation or external design.Self-directedness (...) lies at the nexus of issues concerning the evolution and nature of intentionality, intelligence, and agency. It provides some insight into the evolution of intelligence because it helps explain how organisms are able to manage variable interaction processes, e.g., a hunting strategy that varies with prey type, ground condition, and hunger level. Simple self-directed organisms like bumblebees manage variability in one or a few dimensions. (shrink)

A model of spontaneous collapse of fermionic degrees of freedom in a quantum field is presented which has the advantages that it explicitly maintains energy conservation and gives results in agreement with an existing numerical method for calculating quantum state evolution, namely the quantum trajectories model.

This is the third of five chapters on good, and inquires into what kinds of things are intrinsically good. The first thing claimed as intrinsically good is virtuous disposition and action; the second is pleasure in itself. These two approaches are briefly analysed, with the goodness or badness of pleasure given particular attention. Ross concludes that four things can be seen to be intrinsically good—virtue, pleasure, the allocation of pleasure to the virtuous, and knowledge. He is unable to discover anything (...) that is intrinsically good that is not either one or a combination of these. (shrink)

This is the second of five chapters on good, and starts by making the point that it is around the question of the intrinsically good that the chief controversies about the nature of goodness or value revolve, for most theories of value may be divided into those that treat it as a quality and those that treat it as a relation between that which has value and something else ; Ross says that it seems clear that any view that treats (...) goodness as a relation between that which is good and something else denies that anything is intrinsically good. The chapter first discusses R. B. Perry's relational view of value—in the sense of good, and other theories that also identify goodness with some relation, either as a relation between that which is good and some or all of its elements, or as a relation between some or all of its elements, or as a relation between it or some or all of its elements and something else. Next, the psychological theories of good are discussed; these, as a rule, hold that a thing being good means either that some person or persons have some feelings towards it, or some person or persons think it to be good; this is an objective view of good. The rest of the chapter looks at both R. B. Perry's and G. E. Moore's arguments on these theories, at Ross's own views, at badness as incompatible with goodness or as an element of a good thing, at W. M. Urban's work on the question of values, and at B. Croce's arguments on value judgements. Ross concludes that the arguments in favour of thinking of value as an objective are no more successful than those in favour of treating it as a relation, and presents a lengthy validation of his conclusion, based largely on discussion of beauty and goodness.

This is the fourth of five chapters on good, and looks at the question of whether goods are commensurable—measurable in degrees. As a preliminary, the question is asked as to whether pleasures are commensurable, and as a preliminary to that question, whether pleasures are comparable, and whether one pleasure can be said to be greater or more pleasant than another. The chapter examines two of three aspects of degrees of goodness: the commensuration of pleasures against one another; and the commensuration (...) of different states of knowledge against one another, including the dependence of the value of a state of knowledge on the nature of the state of mind, and the value of a state of opinion ; the third aspect, the balancing of virtuous actions and dispositions against one another, is examined in the next chapter. The question is then addressed as to whether virtue, knowledge, and pleasure can be compared in value—measured against one another; here, evidence is put forward to support Ross's view that pleasure is inferior in value to virtue and knowledge. The last part of the chapter looks at the relative value of moral goodness and value as ends in themselves. (shrink)

This is the last of five chapters on good, and examines moral goodness. Ross explains the concept of morally good as either being a certain sort of character or being related in one of certain definite ways to a certain sort of character. The matter of what kinds of things are morally good is then addressed, and further advances made in defining moral goodness. These begin by considering Immanuel Kant's views on the desire to do duty, and go on to (...) consider conscientious—or virtuous—actions, scales of moral goodness, types of good desire, and bad actions. (shrink)

This first chapter of Ross's book is devoted to an inquiry into the meaning of right. The interest throughout is ethical, with value only being discussed as far as it seems relevant. The first aspect addressed is the ambiguity inherent in any definition of the meaning of right. G. E. Moore's three definitions of a horse are discussed: these may be designated the arbitrary verbal definition, the verbal definition proper, and the definition that involves the sense of being reduced to (...) elements simpler than itself. These three types of definition are applied to the subsequent discussion of the meaning of right, which includes looking at the difference between right and duty, at moral goodness, at the reduction of right to elements simpler than itself, at right definable as productive of a certain outcome, at ethical principles, at hedonistic utilitarianism, and at the sociological school. (shrink)

Having discussed right in the first two chapters of the book, the remaining five discuss good, starting here with an analysis of the meaning of good. The analysis starts by showing that the senses in which ‘good’ is used can essentially be divided into two: adjunctive or attributive—to persons or things; and predicative. These two different usages are discussed in detail in the rest of the chapter.

This second chapter continues the inquiry into right started in the first, asking what makes right acts right. Historical attempts to state a single characteristic of all right actions that is the foundation of their rightness have been based on egoism and utilitarianism; these are not discussed except in so far as they are contrasted with the other theory put forward, which is G. E. Moore's theory suggesting that what makes actions right is that they are productive of good. The (...) main aspect of this addressed is that of duty, and the consideration leads to a rejection of the definition of right as just productive of the best possible consequences. The connection between the attributes of right and optimific is discussed, and the nature of acts that are right is explored in more detail. Two appendices follow Chapter II: the first discusses rights ; the second discusses punishment. (shrink)

This volume examines some of the arguments that have been put forward over the years to explain the way in which understanding is acquired. The author looks firstly at the empricist thesis of genesis without structure, and secondly at the opposing theory, represented by Chomsky of structure without genesis. His greatest sympathy is with the theory of Piaget, who represents structure with genesis. He considers that Piaget's account is flawed, however, by its biological model and by its failure to deal (...) adequately with the problem of objectivity. The second part of the book contains chapters on language, the differences between early and later learning, and on teaching. The book provides a general understanding of the principles that make it possible, and the differences between the ways in which they work at different stages. (shrink)

Previous work has shown that spontaneous collapse of Fock states of identical fermions can be modeled as arising from random Rabi oscillations between two states. In this paper, a mathematical formalism is presented to incorporate this into many-body quantum field theory. This formalism allows for nonlocal collapse in the context of a relativistic system. While there is no absolute time-ordering of events, this approach allows for a coherent narrative of the collapse process.

Background. South Africa (SA) currently has a golden opportunity to legislate on human heritable genome editing (HHGE), as the country is revising its assisted reproductive technology regulations. A set of sub-regulations that deals with HHGE, which could seamlessly slot into the current regulations, has already been developed. The principles underlying the proposed set of sub-regulations are as follows: HHGE should be regulated to improve the lives of the people and should not be banned; the well-established standard of safety and efficacy (...) should be used in the regulation of HHGE; quality of life is what matters, and not preserving a ‘normal’ genome; parents’ reproductive autonomy must be respected; and equality of access to approved HHGE technology should be promoted. Objectives. To ascertain whether the proposed set of sub-regulations that deals with HHGE is aligned with public opinion in SA, and SA’s Bill of Rights. Methods. Public opinion in SA is determined with reference to a deliberative public engagement study on HHGE conducted among South Africans, and the relevant rights in the Bill of Rights are interpreted with reference to recent case law. Results. This proposed set of sub-regulations that deals with HHGE is aligned with public opinion in SA, and SA’s Bill of Rights. Conclusion. Despite the legal and ethical complexities of HHGE, the proposed set of sub-regulations provides a targeted and effective legislative approach. They fit seamlessly into the country’s existing health law framework, creating specific legal standards for HHGE that align with both public opinion and the country’s Bill of Rights. (shrink)

Originally published in 1957, the primary aim of this study was to shed light upon the logical character of the psychology of perception. D.W. Hamlyn begins by delimiting the field of psychological inquiry into perception, then gives a detailed account of the types of explanation appropriate in the field. He maintains that these explanations have certain important peculiarities which distinguish them from other scientific inquiries. In view of the central importance of Gestalt Theory in this field an account is given (...) of its origins, and its main features are critically discussed. The work should still be of considerable interest to both philosophers and psychologists, as well as to all those interested in the relations between the two subjects. (shrink)

Primary to both ontology and epistemology is the attributional union that properties and relations have with their subjects. Yet, the tradition’s understanding of attribution has been assessed as shallow, and its contemporary analysis deemed locked in a non-progressing stalemate. Central here is the historically dominant __in___herence_/_constituent_ construal of attribution, what, I argue, has remained obscure and unattended as to its background assumptions and their implications. On the analysis offered herein, I make precise and detail errors of the defining assumptions of (...) inherence theory and the _two-tiered nature_ it requires of attribution. Brought into relief will be the four elements involved in every attributional union, and what are the errors in a sequence of collapsing identities among them that define inherence theory. Along the way, clarification and warrant is provided for the alternative theses and their implications defining an __ad___herence_ theory of attribution, key features synopsized in the last section.

This book provides an introduction to metaphysics. At the outset Professor Hamlyn distinguishes two conceptions of metaphysics running through the history of the subject. One, which goes back to Aristotle, is concerned with ontology, and with what has to exist for beings such as we are; the other separates appearance and reality and attempts to establish what really exists. Professor Hamlyn's account of metaphysics conforms with the first tradition. This is not, however, primarily a historical exposition. The discussion concentrates on (...) central metaphysical concepts and problems, including the principles of ontology, substance, particulars and universals, monism and pluralism, space and time, minds, selves and personal identity. Throughout, Professor Hamlyn's thoroughly informed and argued consideration of the topics presents both a persuasive view of the subject and an excellent grounding in it. (shrink)

It is through our actions that we affect the way the world goes. Whenever we face a choice of what to do, we also face a choice of which of various possible worlds to actualize. Moreover, whenever we act intentionally, we act with the aim of making the world go a certain way. It is only natural, then, to suppose that an agent's reasons for action are a function of her reasons for preferring some of these possible worlds to others, (...) such that what she has most reason to do is to bring about the possible world which, of all those available to her, is the one that she has most reason to want to obtain. This is what is known as the `teleological conception of practical reasons'. Whether this is the correct conception of practical reasons is important not only in its own right, but also in virtue of its potential implications for what sort of moral theory we should accept. Below, I argue that the teleological conception is indeed the correct conception of practical reasons. (shrink)

In this lecture Armstrong argues that the main point of difference between Saint Augustine and other Christian Platonists centers less on how they view the effectiveness of man's free will than on their view of man's relationship to God. The Platonic tradition always stressed the goodness of the deity. Augustine, however, stressed God's immutability and power, and paid little attention to His goodness and His offer of redemption to all men, including those who stand outside the institutionalized church. This engaging (...) 1966 Saint Augustine Lecture is an unabashed polemic which is cast within an examination of three topics which illustrate Augustine's relationship to pagan and Christian Platonism. The criticism is stated with refreshing boldness and masterly erudition. The extensive notes are stimulating and informative. In the first section the author discusses the natural divinity of the soul and tells why most Christian thinkers, including Augustine, rejected the Platonic view that man's soul is naturally divine. The second topic presents the different attitudes Augustine and Platonism expressed toward the body and the material universe. Here Armstrong argues that in their fervent rejection of the Plotinian doctrine of the mystical body of the universe, Christians lost the sense of the holiness of everyday life and thereby dampened their awareness of the immediacy of the Holy Spirit. In his last topic of discussion Armstrong preaches against Augustine's doctrine of selective predestination and his conception of God as an arbitrary tyrant. These two views, says Armstrong, bring bad news to mankind and cause extreme pessimism rather than an awakening of love--the motive force which speeds man back to God.--W. D. T. (shrink)
