Norms of Nature


Book Description

The components of living systems strike us as functional-as for the sake of certain ends—and as endowed with specific norms of performance. The mammalian eye, for example, has the function of perceiving and processing light, and possession of this property tempts us to claim that token eyes are supposed to perceive and process light. That is, we tend to evaluate the performance of token eyes against the norm described in the attributed functional property. Hence the norms of nature. What, then, are the norms of nature? Whence do they arise? Out of what natural properties or relations are they constituted? In Norms of Nature, Paul Sheldon Davies argues against the prevailing view that natural norms are constituted out of some form of historical success—usually success in natural selection. He defends the view that functions are nothing more than effects that contribute to the exercise of some more general systemic capacity. Natural functions exist insofar as the components of natural systems contribute to the exercise of systemic capacities. This is so irrespective of the system's history. Even if the mammalian eye had never been selected for, it would have the function of perceiving and processing light, because those are the effects that contribute to the exercise of the visual system. The systemic approach to conceptualizing natural norms, claims Davies, is superior to the historical approach in several important ways. Especially significant is that it helps us understand how the attribution of functions within the life sciences coheres with the methods and ontology of the natural sciences generally.

The Integration of Functions of a Single Variable


Book Description

From the PREFACETHIS tract has been long out of print, and there is still some demand for it. I did not publish a second edition before, because I intended to incorporate its contents in a larger treatise on the subject which I had arranged to write in collaboration with Dr. Bromwich. Four or five years have passed, and it seems very doubtful whether either of us will ever find the time to carry out our intention. I have therefore decided to republish the tract.The new edition differs from the first in one important point only. In the first edition I reproduced a proof of Abel's which Mr. J. E. Littlewood afterwards discovered to be invalid. The correction of this error has led me to rewrite a few sections (pp. 36-41 of the present edition) completely. The proof which I give now is due to Mr. H. T. J. Norton. I am also indebted to Mr. Norton, and to Mr. S. Pollard, for many other criticisms of a less important character.--G. H. H




What Biological Functions Are and Why They Matter


Book Description

This accessible book presents a new theory of biological functions and connects it to contemporary problems in philosophy and science.




Law for Society


Book Description

Law for Society: Nature, Functions, and Limits offers an illuminating conceptual framework that looks at five basic legal instruments with which the law addresses the problems and goals of society. For any Introduction to Law course or as secondary reading in political science, criminal justice, or general studies, Law for Society breaks down the very concept of “law” to answer the questions: What is law? How does law work? What can law do and not do? The book addresses the nature of law, its problem-solving functions, and the limits on what law can accomplish.




The Nature and Functions of Dreaming


Book Description

The Nature and Function of Dreaming presents a comprehensive theory of dreaming based on many years of psychological and biological research by Ernest Hartmann and others. Critical to this theory is the concept of a Central Image; in this volume, Hartmann describes his repeated finding that dreams of being swept away by a tidal wave are common among people who have recently experienced a trauma of some kind - a fire, an attack, or a rape. Dreams with these Central Images are not dreams of the traumatic experience itself, but rather the Central Image reveals the emotional response to the experience. Dreams with a potent Central Image, like the tidal wave, vary in intensity along with the severity of the trauma; this pattern was shown quite powerfully in a systematic study of dreams occuring before and after the September 11 attacks in New York.Hartmann's theory comprises three fundamental elements: dreaming is simply one form of mental functioning, occurring along a continuum from focused waking thought to reverie, daydreaming, and fantasy. Second, dreaming is hyperconnective, linking material more fluidly and making connections that aren't made as readily in waking thought. Finally, the connections that are made are not random, but rather are guided by the dreamer's emotions or emotional concerns - and the more powerful the emotion, the more intense the Central Image.
