The history of evolution is a history of development from less to more complex organisms. This growth in complexity of organisms goes hand in hand with a concurrent growth in complexity of environments and of organism-environment relations. It is a concern with this latter aspect of evolutionary development that motivates the present paper. We begin by outlining a theory of organism-environment relations. We then show that the theory can be applied to a range of different sorts of cases, both biological (...) and non-biological, in which objects are lodged or housed within specific environments, or niches. Biological science is interested in types—for example in genotypes, phenotypes, and environment types—in regularities that can serve as the basis for the formulation of laws or general principles. Types, however, can exist only through their corresponding tokens. Our theory of token environments is meant to plug this gap and to provide a first step towards a general theory of causally relevant spatial volumes. (shrink)

ONTOLOGY This book is a book about the world. I am concerned with ontology, not merely with language. Many ontological treatises concentrate largely on the ...

Ontology is currently perceived as the solution of first resort for all problems related to biomedical terminology, and the use of description logics is seen as a minimal requirement on adequate ontology-based systems. Contrary to common conceptions, however, description logics alone are not able to prevent incorrect representations; this is because they do not come with a theory indicating what is computed by using them, just as classical arithmetic does not tell us anything about the entities that are added or (...) subtracted. In this paper we shall show that ontology is indeed an essential part of any solution to the problems of medical terminology – but only if it is understood in the right sort of way. Ontological engineering, we shall argue, should in every case go hand in hand with a sound ontological theory. (shrink)

John Searle began to discuss his recently published book `The Construction of Social Reality' with Anthony Freeman, and they ended up talking about God. The book itself and part of their conversation are introduced and briefly reflected upon by Anthony Freeman. Many familiar social facts -- like money and marriage and monarchy -- are only facts by human agreement. They exist only because we believe them to exist. That is the thesis, at once startling yet obvious, that philosopher John Searle (...) explores in The Construction of Social Reality. (shrink)

"Cyberspace" is a term used commonly but without adequate definition. All computer-mediated phenomena may be said to comprise cyberspace. So far, no adequate ontology of cyberspace has been formulated. The law of intellectual property has attempted to fit computer-mediated phenomena into the current legal scheme. Currently, the law of intellectual property distinguishes between the subjects of patent law , and the subject of copyright law . The distinction embodied in the law of intellectual property is invalid and all things which (...) are man-made and intentionally produced are expressive objects. All computer-mediated phenomena are such expressive objects. The law of intellectual property comprises a naive ontology. A common-sense ontology of intellectual property, which must abide by the rules of logic, recognizes that all man-made objects which are intentionally produced are expressive objects and should be afforded the same form on intellectual property protection. The current legal ontology has failed in devising mutually exclusive categories for objects which are of the same type, namely--expressive. A unified ontology would accommodate computer-mediated phenomena without the problems which result from the current naive ontology. (shrink)
