We extend the monotonic and regular modal logics to the multi-modal cue, and give semantical characterization w.r.t. a semantics of minimal frames. For this we introduce a calculus over neighbourhoods and we obtain simpler conditions than those from the literature.
There seems to be no clear consensus in the existing literature about the role of deontic logic in legal knowledge representation — in large part, we argue, because of an apparent misunderstanding of what deontic logic is, and a misplaced preoccupation with the surface formulation of legislative texts. Our aim in this paper is to indicate, first, which aspects of legal reasoning are addressed by deontic logic, and then to sketch out the beginnings of a methodology for its use in (...) the analysis and representation of law.The essential point for which we argue is that deontic logic — in some form or other —needs to be taken seriously whenever it is necessary to make explicit, and then reason about, the distinction between what ought to be the case and what is the case, or as we also say, between the ideal and the actual. We take the library regulations at Imperial College as the main illustration, and small examples from genuinely legal domains to introduce specific points. In conclusion, we touch on the role of deontic logic in the development of the theory of normative positions. (shrink)
. The current literature in the Artificial Intelligence and Law field reveals uncertainty concerning the potential role of deontic logic in legal knowledge representation. For instance, the Logic Programming Group at Imperial College has shown that a good deal can be achieved in this area in the absence of explicit representation of the deontic notions. This paper argues that some rather ordinary parts of the law contain structures which, if they are to be represented in logic, will call for use (...) of a reasonably sophisticated deontic logic.

The paper discusses the potential value of a deontic approach to database specification. More specifically, some different types of integrity constraints are considered and a distinction is drawn between necessary (hard) and deontic (soft) constraints.Databases are compared with other normative systems. A deontic logic for database specification is proposed and the problems of how to react to, and of how to correct, or repair, a situation which arises through norm violation are discussed in the context of this logic. The limitations (...) of the proposed logic and possible modifications and extensions of it are analysed. (shrink)
Is archaeology an art or a science? This question has been hotly debated over the last few decades with the rise of archaeological science. At the same time, archaeologists have seen a change in the intellectual character of their discipline, as many writers have adopted approaches influenced by social theory. The discipline now encompasses both archaeological scientists and archaeological theorists, and discussion regarding the status of archaeology remains polarised. Andrew Jones argues that we need to analyse the practice of archaeology. (...) Through an analysis of archaeological practice, influenced by recent developments in the field of science studies, and with the aid of extensive case studies, he develops a new framework which allows the interpretative and methodological components of the discipline to work in tandem. His reassessment of the status and character of archaeology will be of interest to students, scholars and professionals. (shrink)
This paper is a preliminary investigation into the application of the formal-logical theory of normative positions to the characterisation of normative-informational positions, pertaining to rules that are meant to regulate the supply of information. First, we present the proposed framework. Next, we identify the kinds of nuances and distinctions that can be articulated in such a logical framework. Finally, we show how such nuances can arise in specific regulations. Reference is made to Data Protection Law and Contract Law, among others. (...) The proposed approach is articulated around two essential steps. The first involves identifying the set of possible interpretations that can be given to a particular norm. This is done by using formal methods. The second involves picking out one of these interpretations as the most likely one. This second step can be resolved only by using further information (e.g., the context or other parts of the regulation). (shrink)
The hacker culture is neither good nor evil, but instead focuses on getting results. It is self-reliant and rooted in an anti-authoritarian embrace of individuality. No citizen is beholden to any single person, only to the quality of work being done.
In this paper we attempt to supply answers to questions of the following kinds: How are database Integrity Constraints to be characterised formally? How is the concept of violation of an IC to be understood? What is the epistemic status of an IC? Following an analysis of the standard treatment of ICs, based on a simple example, we recall how Reiter provided a clear definition of the epistemic status of ICs. On Reiter's approach, ICs are implicitly supported by statements that (...) are guaranteed to be true; this property is explicit in the standard view of ICs, and we proceed to show how the standard view of ICs may be refined in the light of Reiter's work. We then supply formal definitions of the properties of Validity and Completeness which have to be enforced using ICs, and we give general formal results concerning techniques which can be used to check these properties. We propose to split the overall information involved in Integrity Checking into three components called DB, SAF and IC. DB represents a description of the world that is not necessarily guaranteed to be correct; SAF represents the information about the world that is guaranteed to be true, and which is used to check violations of Validity or Completeness; and IC defines the parts of DB for which the properties of Validity or Completeness must be enforced.

Previous discussions of Kant’s influence on German biology have resulted in contradictory accounts. Zammito argues both that Kant could not have influenced German biology because his account is fundamentally incompatible with the presuppositions of biological naturalism, and biology only emerged because biologists misunderstood Kant’s philosophy. I argue that his account exposes an important difficulty when considering Kant’s influence on the development of biology, since it correctly identifies a fundamental incompatibility between biological naturalism and Kant. However, this does not demonstrate that (...) Kant could not have been influential on the development of biology. Instead, I propose a broader conception of influence that includes both intentional and non-intentional forms of misunderstanding. I examine Kant’s influence on the development of biology in the British Isles. Both in the history of science and contemporary research, the literature tends to focus on Kant’s ‘Critique of Teleological Judgment’ as this is where Kant discusses how biological entities require us to judge them as if they possessed the properties of self-organization, growth and reproduction. I argue that Kant’s influence on biology in the British Isles originates from his account of scientific methodology in his earlier work, the Critique of Pure Reason. Kant’s account was influential on William Whewell. Kant argued that the unity of science was merely a presupposition for scientific enquiry, whereas Whewell argued this unity was an inherent property of the world that science was discovering. I argue that Whewell intentionally misinterpreted aspects of Kant’s philosophy to develop a more naturalistic theory of science. Whewell was influential on the development of Darwin’s scientific methodology in the Origin as he argues for the correctness of his theory on the basis that it displays consilience. Whewell’s account of science was not only influential for the development of biology but also for more recent accounts of scientific methodology and reductivist accounts of science. I argue that this dual philosophical-historical approach provides the basis for a richer, more adequate understanding of how Kant’s philosophy has continued to exert a strong though often unrecognised influence on developments in biological theory such as immunology and contemporary accounts of biological autonomy. All the same that influence is highly problematic because of the original incompatibility between transcendental idealism and biological naturalism. Understanding how aspects of Kant’s philosophy are intertwined with both the development of biology and contemporary philosophy of biology allows us to assess the conjoint costs and benefits of the synthesis between Kant’s philosophy and philosophy of biology.
