The quantitative problem of old evidence is the problem of how to measure the degree to which e confirms h for agent A at time t when A regards e as justified at t. Existing attempts to solve this problem have applied the e-difference approach, which compares A's probability for h at t with what probability A would assign h if A did not regard e as justified at t. The quantitative problem has been widely regarded as unsolvable primarily on (...) the grounds that the e-difference approach suffers from intractable problems. Various philosophers have proposed that 'Bayesianism' should be rejected as a research strategy in confirmation theory in part because of the unsolvability of this problem. I develop a version of the e-difference approach which overcomes these problems and possesses various advantages (but also certain limitations). I develop an alternative 'theistic' approach which handles many cases that my development of the e-difference approach does not handle. I conclude with an assessment of the significance of the quantitative problem for Bayesianism and argue that this problem is misunderstood in so far as it is regarded as unsolvable, and in so far as it is regarded as a problem only for Bayesians.

The December 2008 White Paper (WP) on “Brain Death” published by the President’s Council on Bioethics (PCBE) reaffirmed its support for the traditional neurological criteria for human death. It spends considerable time explaining and critiquing what it takes to be the most challenging recent argument opposing the neurological criteria formulated by D. Alan Shewmon, a leading critic of the “whole brain death” standard. The purpose of this essay is to evaluate and critique the PCBE’s argument. The essay begins with a (...) brief background on the history of the neurological criteria in the United States and on the preparation of the 2008 WP. After introducing the WP’s contents, the essay sets forth Shewmon’s challenge to the traditional neurological criteria and the PCBE’s reply to Shewmon. The essay concludes by critiquing the WP’s novel justification for reaffirming the traditional conclusion, a justification the essay finds wanting. (shrink)

In R. C. Flickinger's (3rd ed. second impression 1929) we read on pp. 171In the iambic trimeters written by Aeschylus a trisyllabic substitution (tribrach, anapaest or dactyl) for the pure disyllabic iambus occurs only once in about twenty-five verses.Tragic Drama of the Greekstrimeters’ lines like.

Most authors who work with moral status automatically dismiss the possibility that plants are the kinds of entities that have moral status. This dismissal coheres with our intuitions about common-sense morality: if plants do not have moral status then we do not have any direct moral obligations to plant life. An implication of such a view is that any suggestion otherwise commits one to be in favour of an absurd conclusion. However, given the recent literature and empirical evidence on plant (...) minds, there are reasons to accept a different perspective that finds the absurd conclusion plausible. (shrink)

It has frequently been observed that the Prometheus Vinctus shows certain Sophoclean characteristics of rhythm. In order to vary the rhythm of his iambics and to avoid monotony, Sophocles often knits consecutive trimeters closely together by placing at the end of one line some word which looks forward to the next line, and so precludes the reader from stopping for the natural pause after the sixth foot. Sometimes he uses in this way subordinating words which introduce a dependent clause in (...) the next line ; sometimes proclitics or quasi-proclitics. (shrink)

Towards the conclusion of his interesting remarks on the meaning of the Homeric phrase, τ δ' πτερος πλετο μθος, Professor J. A. K. Thomson writes, ‘When a classical author uses the word πτερος it means “wingless” or “featherless” and nothing else,’ and he accordingly rejects Headlam's interpretation of πτερος φτις at Aesch. Ag. 288 together with the same scholar's proposal to read at P. V. 707 πτερος for the unmetrical απνδιος It may be true that the phrase, πτρ τάχει, which (...) Headlam adduced in his note on the Agam. passage in support of his rendering, is not by itself convincing, but there are other considerations which Professor Thomson has, I imagine, overlooked. What follows is not an attempt to demonstrate that πτερος does mean ‘wing-swift’ in Aeschylus, but only to suggest that there is evidence to show that the word could bear that meaning in classical Greek authors, and that Headlam's interpretation and emendation should therefore not be rejected out of hand.
