Observations with respect to the relationship between symptoms and diseases can seriously be biased by selection phenomena. This selection may occur from the general population, via consultation behavior, diagnostic and therapeutic activities of the general practitioner, and by referral.Relationships may be suggested and reproduced even if they do not exist in unselected populations, as a product of diagnostic routines. Correction for selection bias can only be achieved by choosing proper comparison groups. While this can be done in a general practice (...) setting, this is almost impossible after referral, as is demonstrated in this paper. Surprisingly, the most unbiased estimation of the relationship between symptoms and diseases after referral can be made from patient groups that are referred for reason unrelated to the disease under study.

Though P. G. Tait was in a seemingly perfect position to teach both William Thomson's thermodynamics and James Clerk Maxwell's electromagnetic theory of light, he did not. Tait probably first encountered the new thermodynamics in the 1850s at Queen's College, Belfast, and presented the ideas in his inaugural lecture at Edinburgh in 1860, soon making energy theory the centre-piece of his course there. The comprehensiveness of energy theory plus Thomson's opposition to Maxwell's electromagnetic theory evidently combined in causing Tait to (...) de-emphasize Maxwell's theory. Ironically, Tait, the loyal Scot, thus inadvertently contributed to what might be termed the Anglicization of Scottish natural philosophy. (shrink)

In ‘Wittgenstein on Language and Rules’, Professor N. Malcolm took us to task for misinterpreting Wittgenstein's arguments on the relationship between the concept of following a rule and the concept of community agreement on what counts as following a given rule. Not that we denied that there are any grammatical connections between these concepts. On the contrary, we emphasized that a rule and an act in accord with it make contact in language. Moreover we argued that agreement in judgments and (...) in definitions is indeed necessary for a shared language. But we denied that the concept of a language is so tightly interwoven with the concept of a community of speakers as to preclude its applicabilty to someone whose use of signs is not shared by others. Malcolm holds that ‘This is an unwitting reduction of Wittgenstein's originality. That human agreement is necessary for “shared” language is not so striking a thought as that it is essential for language simpliciter.’ Though less striking, we believe that it has the merit of being a true thought. We shall once more try to show both that it is correct, and that it is a correct account of Wittgenstein's arguments. (shrink)
Given the fact that both R.G. Collingwood and P.F. Strawson introduced, inspired by Kant, a 'reform of metaphysics' and thereby used a strikingly similar terminology, the absence of an extensive article about the comparison between their concepts of a 'reformed metaphysics' is, to say the least, rather surprising. The first aim of this article is filling up this gap. But there is more at stake. Traditionally, a twofold connection is laid between their concepts of metaphysics. First, there is the fact (...) that both authors consider metaphysics as a reflexion about the basic presuppositions of our thought and so subscribe to Kant's 'reform of metaphysics'. Subsequently, the central point of difference to be considered is that Strawson sets basic presuppositions as universal and invariable and so more directly leans against Kant than Collingwood who ascribes to these presuppositions a variable and cultural-historical character. In this article — and that is its central aim — I would like to make some critical remarks to this interpretation. First, I try to show how the resemblances between their concepts of metaphysics originate from their adoption of both Kants 'Copernican revolution' and his repudiation of transcendent metaphysics. Furthermore, I want to point out the differences between both their concepts of metaphysics, starting from their respective interpretations of Kant s transcendental idealism. While Strawson propounds an 'anodyne' interpretation of transcendental idealism, Collingwood proposes a 'radicalization' of transcendental idealism. Against the backdrop of these different interpretations, the contrast between the universal character of Strawson's metaphysics and the so-called historical-relativist character of Collingwood s metaphysics can be clarified. Finally, I will dwell on six repercussions of both their views of metaphysics. (shrink)
