Facts and values

Cragg, Wesley January 1973 (has links)
The thesis begins with a brief introduction in which I set out a number of the major questions which I intend to consider. I indicate that the focus for discussion will be functional words. Two questions regarding functional words are asked. First, do they have descriptive content? Second, do they have evaluative content? After a brief discussion, I attempt to set out the significance of these two questions. I point out that both are potentially significant relative to recent controversies over how description is related to evaluation. I indicate, however, that my chief concern will not be with the prescriptivist/naturalist controversy; rather, my chief concern will be with attempting to discover the role played by functional words in both descriptive and evaluative contexts The purpose of the discussion will be to discover whether an analysis of functional words can shed any light on the nature of the fact/value relationship. After raising a number of subsidiary questions, which, it is hoped, will aid the reader in following the argument, I introduce some terminology of which the notion of an F-word is central. A definition of 'F-word' is provided in Chapter II. The 'definition' with which the notion is introduced is simply that an F-word is any word which is like functional words in relevant respects. [page ii of abstract missing] In Chapter IV the discussion turns to a detailed examination of a suggestion of Hare in The Language of Morals. I find it necessary to reconstruct his suggestion and find it contains three elements. Of these three elements I argue that Hare is correct in thinking that in F-inferences, a standard of evaluation is introduced by the use of an F-word. I then argue that Hare is incorrect in thinking that, as in inferences from pure descriptions to hypothetical imperatives, the standard of evaluation in F-inferences is introduced via the conclusion of the inference. Finally, I argue that Hare is incorrect in his view that both hypothetical imperatives and F-conclusions are analytic qua their imperative or evaluative content. I then point out that F-conclusions and hypothetical imperatives; are dissimilcir in this important respect, namely, that unlike hypothetical imperatives, evaluations entailed by F-descriptions are genuine evaluations. Chapter V is a summary of the conclusions which follow from the arguments of the first part of the thesis. I conclude that F-words do have both descriptive and evaluative content. Further, that their descriptive and evaluative content derive from the same source, namely, the fact that F-words identify objects by reference to their function. Because of this, the descriptive content of F-words cannot be separated off from their evaluative content and expressed in descriptive sentences which have no evaluative content. In this sense, F-words and F-descriptions cannot be eliminated. The chapter closes by asking whether there is a second sense in which F-words cannot be eliminated. I ask, 'Are F-words such that to eliminate them from one's descriptive vocabulary is to eliminate the possibility of using descriptive language?' The over all purpose of Part II is to answer the question posed at the conclusion of Part I. I begin that task with a two chapter examination of the relation between perception and goal directed behavior. The basis of the argument is the proposition that if the ability to engage in goal directed behavior is a necessary condition of perception, then the purposes or goals which guide human conduct will be reflected in the ways we identify things. The discussion in Chapter VI and VII revolves around three questions: (i) is perception a necessary feature of goal directed behavior? (ii) is perception itself a form of goal directed behavior? (iii) is there a necessary relation between perception and agency such that it is logically necessary that perceivers are agents? The first two questions are discussed in Chapter VI, the third in Chapter VII. The first question finds a positive answer. A thing which is incapable of perception is incapable, as a consequence, of goal directed behavior. The second question is answered negatively. I point out, however, that perception does exhibit a number of characteristics whose possession suggests that perception has much in common with goal directed behavior. Chapter VII considers the question 'Is there a logically necessary relation between perception and agency such that only agents are capable of perception?'. I argue that: (i) it is logically necessary that something be an agent if it is to be determined that it is a percipient thing; (ii) only if a percipient thing is an agent can it be determined what it is capabl of perceiving; (iii) there is convincing empirical evidence which demonstrates that perceptual skills are acquired in the context of goal directed behavior and further that this does have an important bearing on what someone does in fact perceive; but (iv) the kinds of arguments which attempt to show that percipient things logically must be agents are unconvincing. The next two chapters turn to a discussion of the relation between description and goal directed behavior. I argue that the use of descriptive language for communication is possible only to agents. Descriptive uses of language can be taught only if it is possible to establish publicly what the words in the language mean. A number of arguments are used to show that this is a genuine problem and one which cannot be overcome by non-agents. From this it is seen to follow that for communication to be possible, at least some of the objects about which communication takes place must be identified as objects of manipulation. I argue that it follows from this that for descriptive language users, a fundamental and non-eliminable way of identifying objects is as objects of manipulation. Chapter IX is devoted to an attempt to develop and illustrate the conclusions of Chapter VIII through the use of a model. In the course of the discussion, I show that an object of manipulation is an F-object. Chapter X is the concluding chapter of Part II. I conclude that to communicate using descriptive language f an individual must be able to identify at least some of the F-objects which those with whom he wishes to communicate are able to identify. I suggest that this constitutes a second sense in which F-words are not eliminable. Chapter XI comprises Part III of the thesis. Its purpose is to sum up in a brief way the conclusions of the previous two parts. It also suggests in a highly speculative way some possible implications of the position arrived at in the course of previous argument.

The truth about value and the value of truth

Smit, Johannes Petrus 12 1900 (has links)
Thesis (PhD)--University of Stellenbosch, 2003. / ENGLISH ABSTRACT: In this thesis an attempt is made to sketch the outlines of a cognitive theory of ethics, i.e. a theory in which ethical statements are a subset of descriptive statements. It is argued that the good is a quale, and that this quale roughly corresponds to what is often referred to as "pleasure". If this conceptualisation of the good is correct, then the resulting ethical theory is a cognitive, egoist version of ethical hedonism. The thesis proceeds by relating this conceptualisation of the good to economic phenomena. An investigation is then made of the conditions under which the following of a boundedly rational rule is preferable to calculating which one of the possible options available to the actor to follow. It is argued that one such rule is that "truth" should serve as a norm of inquiry. Next the issue of "altruism" is considered. It is argued that our intuitions regarding what egoist action should be are radically untrustworthy. Considerations from evolutionary biology and game theory make it clear that an egoist actor might well be best advised to perform a number of actions that would normally be termed altruistic. The next topic concerns the relation between fact and value. Arguments that claim to undermine the distinction between fact and value are argued to be fallacious. It is also argued that the correct view of the relation between fact and value can help to clarify some of the problems surrounding the conceptualisation of "objectivity". The thesis ends by considering the gains that arise from adopting the position argued for. / AFRIKAANSE OPSOMMING: In hierdie tesis word 'n poging aangewend om 'n kognitiwe teorie van etiek, m.a.w 'n teorie waarbinne etiese stellings 'n subspesie van deskriptiewe stellings is, daar te stel. Daar word geargumenteer dar "die goeie" 'n quale is, en dat hierdie quale rofweg dieselfde objek is as wat dikwels na verwys word as plesier. Indien hierdie siening van "die goeie" korrek is, dan impliseer dit die moontlikheid van 'n kognitiewe, egoïstiese weergawe van etiese hedonisme. Die tesis poog eerstens om die verhouding tussen hierdie siening van "die goeie" en ekonomise fenomene te verduidelik. Daarna word ondersoek ingestel na die kondisies waaronder die volg van 'n begrensde rasionele reël 'n beter opsie vir 'n akteur is as om an al die moontlike opsies te kyk en die beste te kies. Daar word geargumenteer dat die idee dat die "waarheid" die doel van ondersoek moet wees een so 'n reël is. Volgende word daar gekyk na die kwessie van altruïsme. Daar word geargumenteer dat ons intuïsies insake die aard van egoïstiese optrede radikaalonbetroubaar is. Sekere kwessies in evolusionêre biologie en spelteorie laat dit blyk dat 'n egoïstiese akteur waarskynlik verskeie oënskynlik "altruïstiese" aksies behoort uit te voer. Die volgende kwessie wat bespreek word is die verhouding tussen feite en waardes. Daar word geargumenteer dat pogings om hierdie onderskeid te ondermyn nie suksesvol is nie. Daar word verder geargumenteer dat die korrekte siening insake hierdie verhouding sekere probleme insake die verstaan van "obkjektiwiteit" kan ophelder. Die tesis eindig deur die voordele wat uit spruit uit die aanvaarding van die posisie wat hier voor geargumenteer word. / National research Foundation (NRF)
