Coherence as a Test for Truth

This paper sets out to demonstrate that a contrast can be drawn between coherentism as an account of the structure of justification, and coherentism as a method of inquiry. Whereas the former position aims to offer an answer to the ‘regress of justification’ problem, the latter position claims that coherence plays a vital and indispensable role as a criterion of truth, given the fallibility of cognitive methods such as perception and memory. It is argued that ‘early’ coherentists like Bradley and Blanshard were coherentists of the latter kind, and that this sort of coherentism is not open to certain sorts of standard objection that can be raised against justificatory coherentism

Does ‘Ought’ Imply ‘Can’? And Did Kant Think It Does?

The aim of this article is twofold. First, it is argued that while the principle of ‘ought implies can’ is certainly plausible in some form, it is tempting to misconstrue it, and that this has happened in the way it has been taken up in some of the current literature. Second, Kant’s understanding of the principle is considered. Here it is argued that these problematic conceptions put the principle to work in a way that Kant does not, so that there is an important divergence here which can easily be overlooked

Going Beyond the Kantian Philosophy: On McDowell's Hegelian Critique of Kant

The Kant-Hegel relation has a continuing fascination for commentators on Hegel, and understandbly so: for, taking this route into the Hegelian jungle can promise many advantages. First, it can set Hegel's thought against a background with which we are fairly familiar, and in a way that makes its relevance clearly apparent; second, it can help us locate Hegel in the broader philisophical tradition, making us see that the traditional "analytic jump from Kant to Frege leaves out a crucial period in post-Kantian thought, third, it can show Hegel in a progressive light, as attempting to take that tradition further forward; fourth, it can help us locate familiar philisophical issues in Hegelian thought that other-wise can appear whooly sui generis; and finally, and perhaps most importantly of all, focusing on this relation can help raise and crystalise some of the fascinating ambiguties concerning Hegel's outlook, regarding whether Hegel's response to Kant shows him to have been a reactionary, Romantic, pre-critical thinker, who sought to turn the philosophical clock back to a time before Kant had written, or a modernist, Enlightented and essentially critical one, who remained true to the spirit if not the letter of Kant's philosophy

Is the galactic corona produced by galactic flares?

The effect of the differential rotation of the disk of the Galaxy on magnetic field which penetrates the disk is considered. The magnetic field will be progressively distorted from a potential (current-free) form and will at some stage become unstable. It is expected that an MHD instability, a resistive instability, or a combination of the two, will result in the release of the excess magnetic energy and that part of the released energy will be converted into heat. By estimating the energy release and the rate at which this process will occur and by assuming that this energy input is balanced by radiation, estimates were obtained of the parameters of the resulting plasma. It appears that this process alone can heat a galactic corona to temperatures of order 10 to the 6th power K

Vection-induced gastric dysrhythmias and motion sickness

Gastric electrical and mechanical activity during vection-induced motion sickness was investigated. The contractile events of the antrum and gastric myoelectric activity in healthy subjects exposed to vection were measured simultaneously. Symptomatic and myoelectric responses of subjects with vagotomy and gastric resections during vection stimuli were determined. And laboratory based computer systems for analysis of the myoelectric signal were developed. Gastric myoelectric activity was recorded from cutaneous electrodes, i.e., electrogastrograms (EGGs), and antral contractions were measured with intraluminal pressure transducers. Vection was induced by a rotating drum. gastric electromechanical activity was recorded during three periods: 15 min baseline, 15 min drum rotation (vection), and 15 to 30 min recovery. Preliminary results showed that catecholamine responses in nauseated versus symptom-free subjects were divergent and pretreatment with metoclopramide HC1 (Reglan) prevented vection-induced nausea and reduced tachygastrias in two previously symptomatic subjects
