In the April number of the Quarterly Mr. Pearson discussed seversal passages of the Rhesus. On two of these I wish to offer a few observations.

There are two motivations commonly ascribed to historical actors for taking up statistics: to reduce complicated data to a mean value (e.g., Quetelet), and to take account of diversity (e.g., Galton). Different motivations will, it is assumed, lead to different methodological decisions in the practice of the statistical sciences. Karl Pearson and W. F. R. Weldon are generally seen as following directly in Galton’s footsteps. I argue for two related theses in light of this standard interpretation, based on a (...) reading of several sources in which Weldon, independently of Pearson, reflects on his own motivations. First, while Pearson does approach statistics from this "Galtonian" perspective, he is, consistent with his positivist philosophy of science, utilizing statistics to simplify the highly variable data of biology. Weldon, on the other hand, is brought to statistics by a rich empiricism and a desire to preserve the diversity of biological data. Secondly, we have here a counterexample to the claim that divergence in motivation will lead to a corresponding separation in methodology. Pearson and Weldon, despite embracing biometry for different reasons, settled on precisely the same set of statistical tools for the investigation of evolution. (shrink)

The sequence from ideal state to tyran I ny contained in Books VIII-IX of the Republic constitutes neither history nor philosophy of history, but rather completes Plato's overall theory of politics, dealing, like every theoretical science, with simplified or pure cases, and narrated purely for dramatic effort. Popper's view that Plato was fundamentally an historicist is incorrect. Plato makes no straightforward comments on philosophy of history. Perhaps, like many Greeks, he surveyed history pessimistically, but he did not propound an iron (...) law of decay. As a social scientist Plato held that there are laws of political change without supposing the course of history is unalterably fixed. (shrink)

Philosophy of history is not a subject which has hitherto attracted much attention in this country. Preoccupation with the methods and achievements of the natural sciences, and distaste for the sort of rationale of history as a whole which Hegel and others offered under the title in the early nineteenth century, have served to make most British philosophers accord its problems only the most casual recognition. It is therefore all the more interesting to find an English writer of unusual powers (...) both of argument and expression, who was himself an historian of distinction in his special field, devoting a large part of his philosophical thinking to the problems of historical knowledge and their wider implications. Unfortunately, R. G. Collingwood was not able to begin the major work on philosophy of history, to writing which, as we are told in the introduction to the present book, he had looked forward for twenty-five years, until his powers were seriously affected by bad health, and he did not live to complete it. But though the full results of his thinking on the subject are lost, we are now able, thanks to the skilful work of his friend Professor T. M. Knox, to study what is in effect an extensive interim report on it. Professor Knox has produced The Idea of History largely on the basis of lectures which Collingwood prepared in 1936, supplemented by two essays already published which date from the same period and a certain amount of material from the unfinished Principles of History written in 1939.

Even though for Hegel the historian rethinks, positions not as past but as necessary stages in his own philosophical development, the history of philosophy remains external to philosophy proper since a genius could work out from the beginning the stages in the Idea's progress. Hegel's critical history allocates space according to philosophical, not historical considerations, saying little about historical contexts. Non-Hegelians also emphasize assessment more than narration, and all historians of the arts and sciences must make judgments of both importance (...) and value. The history of philosophy, however, has become more historical; assessment requires understanding a philosopher's meaning through his historical situation. (shrink)
