This paper develops the ideas of the Swiss zoologist Adolf Portmann or, more precisely, his concept of organic self-representation, wherein Portmann considered the outer surface of living organisms as a specific organ that serves in a self-representational role. This idea is taken as a starting point from which to elaborate Portman’s ideas, so as to make them compatible with the theoretical framework of biosemiotics. Today, despite the many theories that help us understand aposematism, camouflage, deception and other phenomena related to (...) the category of mimicry, there still is a need for a general theory of self-representation that would re-synthesize evolutionary, morphogenetic and semiotic aspects of the surface of organisms. Here, Adolf Portmann’s concept of self-representation is considered as an important step towards the biosemiotics of animal form. (shrink)

Homology is among the most important comparative concepts in biology. Today, the evolutionary reinterpretation of homology is usually conceived of as the most important event in the development of the concept. This paradigmatic turning point, however important for the historical explanation of life, is not of crucial importance for the development of the concept of homology itself. In the broadest sense, homology can be understood as sameness in reference to the universal guarantor so that in this sense the different concepts (...) of homology show a certain kind of “metahomology”. This holds in the old morphological conception, as well as in the evolutionary usage of homology. Depending on what is (or was) taken as a guarantor, different types of homology may be distinguished (as idealistic, historical, developmental etc.). This study represents a historical overview of the development of the homology concept followed by some clues on how to navigate the pluralistic terminology of modern approaches to homology.

This book traces the intellectual revolution initiated by Thales in the sixth century BC to its culmination in the metaphysics of Parmenides.

Through criticism and analysis of ancient traditions, Kahn reconstructs the pattern of Anaximander’s thought using historical methods akin to the reconstructive techniques of comparative linguists.

With Carl Gegenbaur and Ernst Haeckel, inspiredby Darwin and the cell theory, comparativeanatomy and embryology became established andflourished in Jena. This tradition wascontinued and developed further with new ideasand methods devised by some of Haeckelsstudents. This first period of innovative workin evolutionary morphology was followed byperiods of crisis and even a disintegration ofthe discipline in the early twentieth century.This stagnation was caused by a lack ofinterest among morphologists in Mendeliangenetics, and uncertainty about the mechanismsof evolution. Idealistic morphology was stillinfluental in (...) Germany, which prevented a fullappreciation of the importance of Darwinstheory of natural selection for comparativemorphology. Evolutionary morphology andembryology failed to contribute significantlyto the modern synthesis of evolutionarybiology, thereby probably delaying theintegration of developmental biology intomodern evolutionary biology. However, Haeckelsstudent Oscar Hertwig, as well as Victor Franzand Alexej N. Sewertzoff from a youngergeneration, all tried to forge their ownsynthetic approaches in which (inspired byHaeckels work) embryology played an importantrole. Important for all three researchers wereattempts to refine, and sometimes redefine, thebiogenetic law, and to find new scientificexplanations for it (and for the manyexceptions to it). Their research was latermore or less forgotten, and had littleinfluence on the architects of the modernsynthesis. As the relationship betweenevolutionary and developmental biology is nowagain rising in importance in the form ofEvo-Devo, we would like to draw attention tohow this earlier research tradition grappledwith similar questions to those now on theagenda, albeit from sometimes quite differentperspectives.

This book is a general survey of the Greeks' extraordinarily rapid advance from a mythological to a rational view of the world and of man's origins and place in the universe. The continuity of this development and the influence of myth on philosophy are closely studied. There is also a constant assessment of the Greeks' approach to modern scientific and philosophical conceptions, including the Darwinian theory, but the affinity of our civilization to theirs is never overstressed.

All volumes of Professor Guthrie's great history of Greek philosophy have won their due acclaim. The most striking merits of Guthrie's work are his mastery of a tremendous range of ancient literature and modern scholarship, his fairness and balance of judgement and the lucidity and precision of his English prose. He has achieved clarity and comprehensiveness.

This two-part volume collects the complete fragments and most important testimonies for the leading presocratic philosophers. The Greek and Latin texts are translated on facing pages and accompanied by a brief commentary for each philosopher.

This book is available either individually, or as part of the specially-priced Arguments of the Philosphers Collection.

Thomas Sebeok and Noam Chomsky are the acknowledged founding fathers of two research fields which are known respectively as Biosemiotics and Biolinguistics and which have been developed in parallel during the past 50 years. Both fields claim that language has biological roots and must be studied as a natural phenomenon, thus bringing to an end the old divide between nature and culture. In addition to this common goal, there are many other important similarities between them. Their definitions of language, for (...) example, have much in common, despite the use of different terminologies. They both regard language as a faculty, or a modelling system, that appeared rapidly in the history of life and probably evolved as an exaptation from previous animal systems. Both accept that the fundamental characteristic of language is recursion, the ability to generate an unlimited number of structures from a finite set of elements (the property of ‘discrete infinity’). Both accept that human beings are born with a predisposition to acquire language in a few years and without apparent efforts (the innate component of language). In addition to similarities, however, there are also substantial differences between the two fields, and it is an historical fact that Sebeok and Chomsky made no attempt at resolving them. Biosemiotics and Biolinguistics have become two separate disciplines, and yet in the case of language they are studying the same phenomenon, so it should be possible to bring them together. Here it is shown that this is indeed the case. A convergence of the two fields does require a few basic readjustments in each of them, but leads to a unified framework that keeps the best of both disciplines and is in agreement with the experimental evidence. What is particularly important is that such a framework suggests immediately a new approach to the origin of language. More precisely, it suggests that the brain wiring processes that take place in all phases of human ontogenesis (embryonic, foetal, infant and child development) are based on organic codes, and it is the step-by-step appearance of these brain-wiring codes, in a condition that is referred to as cerebra bifida, that holds the key to the origin of language.

The extent of the dependence of early Greek cosmogony on mythical conceptions has long been a prolific source of controversy. Views on the subject have varied from Professor Cornford's claim that ‘there is a real continuity between the earliest rational speculation and the religious representation that lay behind it’ to Professor Burnet's extreme statement, ‘it is quite wrong to look for the origins of Ionian science in mythological ideas of any kind.’ The solution of the problem that I wish to (...) suggest is one which should satisfy those who insist on ‘the scientific character of the early Greek cosmology,’ while retaining a direct connection with pre-scientific beliefs—namely, that some, at least, of the earliest philosophers founded their doctrines of the beginning of the universe on a deliberate rationalization of earlier and contemporary mythical ideas. The appearance of notions like the ‘world-egg’ in a number of passages, too well known for quotation, shows that primitive cosmogony assumed an analogy between the generation of the world and the generation of animate creatures. I believe it can be proved that, so far from the ‘renunciation of sexual imagery’ which even Professor Cornford has recently attributed to Anaximander, he and other philosophers retained the habit of regarding cosmogony and anthropogony as parallel phenomena, only substituting for the mythical ‘world-egg’ a more scientific view of the embryo and its development. They looked at the world through the same spectacles as their predecessors, but after wiping from them the rose tint of mythological fancy. (shrink)

In this book, F.M. Cornford explains why the life and work of Socrates stand out as marking a turning-point in the history of thought. He shows how Socrates revolutionized the concept of philosophy, converting it from the study of Nature to the study of the human soul, the meaning of right and wrong, and the ends for which we ought to live. This is, in fact, the story of the whole creative period of Greek philosophy - the Ionian nature of (...) science before Socrates, Socrates himself, and his chief followers, Plato and his pupil Aristotle. It tells of the different contributions each made, and shows how within three centuries the Greek tradition grew to maturity and the fullness of intellectual power. (shrink)

Explores the origin and evolution of the Greek concept of nature up until the time of Plato.

The Presocratics were the founding fathers of the Western philosophical tradition, and the first masters of rational thought. This volume provides a comprehensive and precise exposition of their arguments, and offers a rigorous assessment of their contribution to philosophical thought.
