Theory instantiation tackles the problem of theory reasoning with quantifiers in Vam- pire using an SMT solver. In contrast to AVATAR modulo theories it works locally by instantiating a clause such that its pure theory part becomes inconsistent and can be deleted. We report on the challenges when adding instantiation for the theory of arrays.

Modern Satisfiability Modulo Theories (SMT)solvers are fundamental to many programanalysis, verification, design and testing tools. They are a goodfit for the domain of software and hardware engineering becausethey support many domains that are commonly used by the tools.The meaning of domains are captured by theories that can beaxiomatized or supported by efficient <i>theory solvers</i>.Nevertheless, not all domains are handled by all solvers andmany domains and theories will never be native to any solver.We here explore different theories that extend MicrosoftResearch's SMT solver Z3's basicsupport. Some can be directly encoded or axiomatized,others make use of user theory plug-ins.Plug-ins are a powerful way for tools to supply their custom domains.

The individual's attitude toward the Determiner of Destiny, which is religion, has always an essentially practical coloring. It involves a belief, to be sure, but this belief is never a matter of pure theory; it bears a reference, more or less explicit, to the fate of the individual's values. Hence in nearly every religion which history has studied or anthropology discovered, the question of the future in store for the individual believer has been one of prime importance. The content of this belief is a question for the theologian and the historian of religion; the psychologist, however, may be able to throw some light on the related question why people believe, or fail to believe, in immortality at all. What, in short, are the psychological sources from which this belief springs, and what are the leading types of this belief?

AbstractHans Kelsen is known both as a legal theorist and as an international lawyer. This article shows that his theory of international law is an integral part of the Kelsenian Pure Theory of Law. Two areas of international law are analysed: first, Kelsen's coercive order paradigm and its relationship to the bellum iustum doctrine; second, the Kelsenian notion of the unity of all law vis-à-vis theories of the relationship of international and municipal law. In a second step, the results of Kelsenian general legal theory of the late period – as interpreted and developed by the present author – are reapplied to selected doctrines of international law. Thus is the coercive order paradigm resolved, the unity of law dissolved, and the UN Charter reinterpreted to show that the concretization of norms as positive international law cannot be unmade by a scholarship usurping the right to make law.
