Any author should be happy when commentators on a long book discuss it thoroughly, raise important issues, and show their sensitivity to its main themes. So I want to begin with thanks to Isaac Levi, Peter Machamer, Richard Miller and Dudley Shapere. This is not, of course, to register agreement with all their criticisms. Indeed, that would be impossible, for their perspectives are so varied as to resist integration into a consistent synthesis. Nevertheless, each of them poses problems that my (...) approach to the growth of scientific knowledge must address, and I believe that the combination of their essays greatly advances the discussion.

Einstein, in his “Zur Elektrodynamik bewegter Körper”, gave a physical (operational) meaning to “time” of a remote event in describing “motion” by introducing the concept of “synchronous stationary clocks located at different places”. But with regard to “place” in describing motion, he assumed without analysis the concept of a system of co-ordinates.In the present paper, we propose a way of giving physical (operational) meaning to the concepts of “place” and “co-ordinate system”, and show how the observer can define both the (...) place and time of a remote event. Following Einstein, we consider another system “in uniform motion of translation relatively to the former”. Without assuming “the properties of homogeneity which we attribute to space and time”, we show that the definitions of space and time in the two systems are linearly related. We deduce some novel consequences of our approach regarding faster-than-light observers and particles, “one-way” and “two-way” velocities of light, symmetry, the “group property” of inertial reference frames, length contraction and time dilatation, and the “twin paradox”. Finally, we point out a flaw in Einstein’s argument in the “Electrodynamical Part” of his paper and show that the Lorentz force formula and Einstein’s formula for transformation of field quantities are mutually consistent. We show that for faster-than-light bodies, a simple modification of Planck’s formula for mass suffices. (Except for the reference to Planck’s formula, we restrict ourselves to Physics of 1905.).

Contributed essays on Vedanta philosophy and Sanskrit literature.

Contributed articles on Indic philosophy, Vedic grammer, and classical Sanskrit literature; includes some on the life of Kr̥ṣṇa Mādho Jha, Sanskrit scholar.

Volume 8 of this landmark edition follows Peirce from May 1890 through July 1892—a period of turmoil as his career unraveled at the U.S. Coast and Geodetic Survey. The loss of his principal source of income meant the beginning of permanent penury and a lifelong struggle to find gainful employment. His key achievement during these years is his celebrated Monist metaphysical project, which consists of five classic articles on evolutionary cosmology. Also included are reviews and essays from The Nation in (...) which Peirce critiques Paul Carus, William James, Auguste Comte, Cesare Lombroso, and Karl Pearson, and takes part in a famous dispute between Francis E. Abbot and Josiah Royce. Peirce's short philosophical essays, studies in non-Euclidean geometry and number theory, and his only known experiment in prose fiction complete his production during these years. Peirce's 1883-1909 contributions to the Century Dictionary form the content of volume 7 which is forthcoming. (shrink)

In contrast to The Methods of Ethics, Sidgwick’s Practical Ethics counsels not trying to “get to the bottom of things” in our efforts to reach “some results of value for practical guidance and life.” For Sidgwick, both practical and theoretical ethics should start from the Morality of Common Sense. Although he retained his utilitarian outlook in Practical Ethics, this paper suggests that the Morality of Common Sense has the resources to hold its own against utilitarian revision.

The purpose of the present study was to address the shortcomings of Cronbach’s alpha concerning the semantic overlap between items. Using an example from a motivational measure, the correction of Cronbach’s alpha was applied by partialing out the effects due to conceptual overlap. The significance of Cronbach’s alpha was tested using simulated random data derived from the measure and by estimating the confidence intervals with known and unknown distributions. The results indicated that the uncorrected conceptual overlap coefficient alpha was equal (...) to 0.89 and 0.66 following the correction. After simulating the corrected statistical results, the distribution of alpha with random numbers had an estimate of 95%, equal to 0.41. The lower bound of the corrected alpha distribution was equal to 0.41, suggesting that the corrected alpha could easily belong to the distribution of alpha developed from simulated random numbers. Thus, the semantic overlap between items on a measure represents a significant threat to the validity of the alpha coefficient. (shrink)

This authoritative study explores the relation of John Henry Newman's idea of conscience to what he called conscience "in the ordinary sense of the word." Grave argues that a proper understanding of this distinction is essential to a satisfactory understanding of Newman's thought wherever the notion of conscience enters into it. He examines some neglected difficulties in this area such as the relation between individual conscience and the authority of the church, and the matter of rights of conscience.
