We explore a framework for argumentation (based on classical logic) in which an argument is a pair where the first item in the pair is a minimal consistent set of formulae that proves the second item (which is a formula). We provide some basic definitions for arguments, and various kinds of counter-arguments (defeaters). This leads us to the definition of canonical undercuts which we argue are ...

In recent years, robust performance of the system has been broadly studied as a trending topic among vast array scholars. This paper discusses robustness control laws for complex dynamic networks (CDNs) with deviation argument. We design two categories (linear law and nonlinear law) undisturbed CDNs to achieve exponential synchronization. It is intractable ascertain range function exactly. Henc...

Logic plays a fundamental role in Kant’s transcendental philosophy. The general presupposition is that Kant’s logic can be subsumed under the Aristotelian tradition. However, with respect to this presupposition some problems arise in Kant’s philosophy. This thesis takes a new approach to Kant’s logic: Instead of imposing a logical framework on Kant’s thought this thesis aims at deriving the log...

ibn sina characterizes sidiqin argument as an argument by means of which the existence of necessary being is proved just on the basis of reflecting on the nature of being. he claims that his versions of the argument satisfy the criterion, really. mulla sadra, however, argues first that ibn sina’s arguments are not, properly speaking, based on reflecting on the nature of being, and second that t...

The existence of null arguments in Athabascan languages, and other polysynthetic languages, is a debated topic. We argue that, if the agreement on the verb is the argument, the so-called Pronominal Argument Hypothesis, languages such as Navajo do not have null arguments in the traditional sense. We then outline the diachrony of Athabascan object marking on the verb (by looking at the various co...

After determining one set of skills that we hoped our students were learning in the introductory philosophy class at Carnegie Mellon University, we designed an experiment to test whether they were actually learning these skills. In addition, there were four sections of this course in the Spring of 2004, and the students in Section 1 were taught the material using argument diagrams as a tool to ...

The slippery slope argument (SSA) is generally treated as a fallacy by both traditional and contemporary theories of argumentation, but is frequently used and widely accepted in applied reasoning domains. Experiment 1 tests the hypothesis that SSAs are not perceived as universally weak arguments. The results provide the first empirical demonstration that SSAs vary predictably in their subjectiv...

Entire matrix-valued functions of a complex argument (entire matrix pencils) are considered. Bounds for spectral variations of pencils are derived. In particular, approximations of entire pencils by polynomial pencils are investigated. Our results are new even for polynomial pencils. © 2005 Elsevier Inc. All rights reserved.

Recent developments in cosmology indicate that every history having a nonzero probability is realized in infinitely many distinct regions of spacetime. Thus, it appears that the universe contains infinitely many civilizations exactly like our own, as well as infinitely many civilizations that differ from our own in any way permitted by physical laws. We explore the implications of this conclusi...
