The role of scientific theories in classifying plants and animals is traced from Hennig's phylogenetics and the evolutionary taxonomy of Simpson and Mayr, through numerical phenetics, to present-day cladistics. Hennig limited biological classification to sister groups so that this one relation can be expressed unambiguously in classifications. Simpson and Mayr were willing to sacrifice precision in representation in order to include additional features of evolution in the construction of classifications. In order to make classifications more objective, precise and quantitative, numerical (...) pheneticists limited themselves to representing degrees of phenetic similarity. Finally, present-day cladists can be separated into phylogenetic cladists, who retain much of Hennig's theory of classification, and pattern cladists, who have stripped Hennig's system down to its bare essentials.

In Rationalities in history, the distinguished historian David d'Avray writes a new comparative history in the spirit of Max Weber. In a strikingly original reassessment of seminal Weberian ideas, d'Avray applies value rationality to the comparative history of religion and the philosophy of law. Integrating theories of rational choice, anthropological reflections on relativism, and the recent philosophy of rationality with Weber's conceptual framework, d'Avray seeks to disengage 'rationalisation' from its enduring association with Western 'modernity.' This mode of analysis is contextualised (...) through the examples of Buddhism, Imperial China, and sixteenth-century Catholicism--in the latter case building upon unpublished archival research. This ambitious synthesis of social theory and comparative history will engage social scientists and historians from advanced undergraduate level upwards, stimulating interdisciplinary discourse, and making a significant contribution to the methodology of history. D'Avray explores the potential of this new Weberian analysis further in his companion volume, Medieval religious rationalities"--Provided by publisher. (shrink)

'A mere metaphor', 'only symbolic', 'just a myth' - these tell tale phrases reveal how figurative language has been cheapened and devalued in our modern and postmodern culture. In God and the Creative Imagination, Paul Avis argues the contrary: we see that actually, metaphor, symbol and myth, are the key to a real knowledge of God and the sacred. Avis examines what he calls an alternative tradition, stemming from the Romantic poets Blake, Wordsworth and Keats and drawing on the thought (...) of Cleridge and Newman, and experience in both modern philosophy and science. God and the Creative Imagination intriguingly draws on a number of non-theological disciplines, from literature to philosophy of science, to show us that God is appropriately likened to an artist or poet and that the greatest truths are expressed in an imaginative form. Anyone wishing to further their understanding of God, belief and the imagination will find this an inspiring work. (shrink)

In this thesis I shall summarize and critically examine the central features of the theories of values of four contemporary moral philosophers: A.J. Ayer, C.L. Stevenson, R.M. Hare, and P.H. Nowell - Smith. I shall first look back, however, to the theory of moral philosophy of the most influential 'forefather' of this group, David Hume. Hume's theory stands as a challenge to moral philosophers who would assume that moral judgments are primarily, in some sense, acts of 'reason'. Although our four (...) contemporaries follow Hume in this, his challenge, in the form I shall indicate shortly, will provide the main theme for this thesis. (shrink)
