This chapter introduces the buck-passing account of value and explains the structure of this book in which the account is motivated, defended, and extended. The buck-passing account analyses value in terms of reasons for pro-attitudes. This chapter explains the notion of a reason for a pro-attitude and its component parts, as well as the types of goodness and value that the buck-passing account is an account of. It then sketches several motivations for accepting the buck-passing account rather than its two competitors: the value-first account of reasons for pro-attitudes and the no-priority view. This chapter further clarifies how various distinctions in value can be made according to the buck-passing account and explores whether the buck-passing account is a metaphysical or conceptual thesis. This chapter maps out the structure of the first two parts of the book and explains how the buck-passing account will be extended to provide a reasons-first account of morality, fittingness, ought, and all of practical normativity in the third part of the book.

Apparent Reasons

Besides the problems with detachment, proponents of the view that structural requirements of rationality are normative face the challenge to identify a reason that counts in favour of conforming to rational requirements. There are three possible ways to account for this challenge. The first is to present instrumental or other derivative reasons to conform to rational requirements (5.1). The second is to argue that rational requirements are themselves reasons (5.2). The third is to give some kind of buck-passing account of rational requirements, according to which such requirements are verdictive statements about reasons that exist independently of them (5.3–5.4). Chapter 5 argues that none of these strategies succeed. Finally, two accounts that have claimed to explain the normativity of structural rationality without assuming that rational requirements are necessarily accompanied by reasons, are discussed and rejected: the transparency account (5.5), and the apparent reasons account (5.6).

The Buck-Passing Account of Value (BPA) analyses goodness simpliciter in terms of reasons for pro-attitudes. The Value-First Account (VFA) analyses reasons for pro-attitudes in terms of value. And the No-Priority View (NPV) holds that neither reasons nor value can be analysed in terms of one another. This chapter argues that BPA should be accepted rather than VFA or NPV because if BPA is accepted, then what all the different varieties of goodness have in common can be explained: but if VFA or NPV is accepted, what the different varieties of goodness have in common cannot be explained. In making this argument this chapter motivates and defends accounts of goodness for (prudential value) and goodness of a kind (attributive goodness) in terms of reasons for pro-attitudes. It shows that the objections that have been made to buck-passing accounts of goodness for and goodness of a kind can be overcome and that there are many advantages to accepting such accounts.

According to the No-Priority View (NPV), what it is to be a reason for a pro-attitude cannot be analysed in terms of value but neither can what it is to be good or of value be analysed in terms of reasons for pro-attitudes. NPV has been defended by Jonathan Dancy and W. D. Ross. This chapter argues that there are several reasons to accept the buck-passing account of value (BPA) over NPV. First, BPA explains striking correlations between reasons and value that NPV does not. Second, BPA explains why value does not give non-derivative reasons to have pro-attitudes; NPV cannot do this. Third, BPA is more qualitatively parsimonious than NPV, and, as explained in this chapter, there are strong reasons to prefer more to less qualitatively parsimonious theories. Fourth, BPA explains why similar theoretical debates arise about reasons and value; NPV cannot do this. Fifth, BPA is more informative than NPV.

Conceptual Link

The buck-passing account of values offers an explanation of the close relation of values and reasons for action: of why it is that the question whether something that is of value provides reasons is not ”open.” Being of value simply is, its defenders claim, a property that something has in virtue of its having other reason-providing properties. The generic idea of buck-passing is that the property of being good or being of value does not provide reasons. It is other properties that do. There are, however, at least three versions of the account which differ in their understanding of those “other properties.” The first two versions both assume that non-normative properties provide reasons, the difference being that the second allows that normative properties also provide reasons. Both run into difficulties, which I explain, in trying to defend the claim that non-normative properties provide reasons for action. The third version of the buck-passing account which explains being of value in terms of more specific evaluative properties that are reason-providing remains unpersuasive as well. Once we understand the relation between general and specific properties as a difference in degree, there is no space for a reduction of the one kind of properties to the other. In section II I sketch an alternative account of the relation between reasons and values, which is based on a thesis that I call the Conceptual Link and the claim that values are not just co-extensive with reasons, but explain them.

In the course of several 21-cm observing programmes being carried out by the Leiden Observatory with the 25-meter telescope at Dwingeloo, a fairly complete, though inhomogeneous, survey of the regionl11= 0° to 66° at low galactic latitudes is becoming available. The essential data on this survey are presented in Table 1. Oort (1967) has given a preliminary report on the first and third investigations. The third is discussed briefly by Kerr in his introductory lecture on the galactic centre region (Paper 42). Burton (1966) has published provisional results of the fifth investigation, and I have discussed the sixth in Paper 19. All of the observations listed in the table have been completed, but we plan to extend investigation 3 to a much finer grid of positions.

Resonance Relation

The paper presents a summary of the results obtained by C. J. Cohen and E. C. Hubbard, who established by numerical integration that a resonance relation exists between the orbits of Neptune and Pluto. The problem may be explored further by approximating the motion of Pluto by that of a particle with negligible mass in the three-dimensional (circular) restricted problem. The mass of Pluto and the eccentricity of Neptune's orbit are ignored in this approximation. Significant features of the problem appear to be the presence of two critical arguments and the possibility that the orbit may be related to a periodic orbit of the third kind.

Very High

AbstractClosed expressions for the first, second, and (in some cases) the third moment of atomic transition arrays now exist. Recently a method has been developed for getting to very high moments (up to the 12th and beyond) in cases where a “collective” state-vector (i.e. a state-vector containing the entire electric dipole strength) can be created from each eigenstate in the parent configuration. Both of these approaches give exact results. Herein we describe astatistical(or Monte Carlo) approach which requires onlyonerepresentative state-vector |RV> for the entire parent manifold to get estimates of transition moments of high order. The representation is achieved through the random amplitudes associated with each basis vector making up |RV>. This also gives rise to the dispersion characterizing the method, which has been applied to a system (in the M shell) with≈250,000 lines where we have calculated up to the 5th moment. It turns out that the dispersion in the moments decreases with the size of the manifold, making its application to very big systems statistically advantageous. A discussion of the method and these dispersion characteristics will be presented.

Probe Size

A small electron probe has many applications in many fields and in the case of the STEM, the probe size essentially determines the ultimate resolution. However, there are many difficulties in obtaining a very small probe.Spherical aberration is one of them and all existing probe forming systems have non-zero spherical aberration. The ultimate probe radius is given byδ = 0.43Csl/4ƛ3/4where ƛ is the electron wave length and it is apparent that δ decreases only slowly with decreasing Cs. Scherzer pointed out that the third order aberration coefficient always has the same sign regardless of the field distribution, provided only that the fields have cylindrical symmetry, are independent of time and no space charge is present. To overcome this problem, he proposed a corrector consisting of octupoles and quadrupoles.

Turkish dermatologist, H. Beheet described the disease as recurrent triad of iritis, oral aphthous lesions and genital ulceration. Auto immune disease is the recent focus on the unknown etiology which is still being discussed. Among the other immunosupressive drugs, CyA included in it's treatment newly. One of the important side effects of this drug is gingival hyperplasia which has a direct relation with the presence of teeth and periodontal tissue. We are interested in the ultrastructure of immunocompetent target cells that were affected by CyA in BD.Three groups arranged in each having 5 patients with BD. Control group was the first and didn’t have CyA treatment. Patients who had CyA, but didn’t show gingival hyperplasia assembled the second group. The ones displaying gingival hyperplasia following CyA therapy formed the third group. GMC of control group and their granules are shown in FIG. 1,2,3. GMC of the second group presented initiation of supplementary cellular activity and possible maturing functional changes with the signs of increased number of mitochondria and accumulation of numerous dense cored granules next to few normal ones, FIG. 4,5,6.
