Principle of Interval Knowledge in Science Methodology

The article discusses the Principle of Interval Knowledge designed to fill the gap in the methodology of science, associated with the problem of the knowledge boundaries. Over the course of half a century, several versions of the Intervality Principle have been created, different interpretations of its notions have arisen, in­cluding the key concept of “abstraction interval”, but they encountered a number of contradictions. Therefore, the task arises of creating a unified concept and in­troducing precise definitions. The author shows that overcoming contradictions is possible on the way of studying the meaning of introduced notions. This meaning should be correlated with the goal of the intervality concept: to reflect the birth of partial knowledge under the conditions of total restrictions of all components in­volved in the creation of knowledge. The article provides definitions of interval notions, formulation of the Principle and interpretation of the key concept “ab­straction interval”. The author believes that the expansion of the notion of “inter­val” allows accepting it as a generic concept for all types of restrictions. The crite­rion for the meaning of a key concept is the requirement of informational completeness of knowledge representation. Then the concept of “abstraction in­terval” can be understood as a complete informational characteristic of knowledge about a fragment of reality and the conditions for its creation. Two comple­mentary concepts are introduced: “conditions interval” and “content interval”. The author shows that the essence of the Principle consists of asserting condition­ality of the content interval by the conditions interval. The introduced refinements remove the contradictions between different directions and lead to the creation of a unified interval concept.

The discursive construction of the separation wall at Abu Dis

The article analyses the discursive function of graffiti on the separation wall in the contested space of Abu Dis on the boundary between Jerusalem and the Occupied Territories. This study explores the role of graffiti as micro-level, political discourse designed to influence national and international actions concerning the Palestinian-Israeli conflict over national borders, self determination and human rights. The data for this study consisted of photographic documentation of the Abu Dis graffiti. This data was analysed for its linguistic and informational characteristic, its political functions, and discursive construction. The results of the study reveal that the separation wall is constructed in five different ways that directly interact with the Palestinian-Israeli conflict. The graffiti on the wall at Abu Dis is a microcosm of the broader conflict and offers an insight into the different chains of political discourse in action in the discussion of the Palestinian-Israeli conflict.
