The paper first proposes a new definition of religion which features a novel four-layered element and which does not involve any circularity (as some definitions do); thereby, it allows to clearly distinguish the phenomenon of religion from certain other worldviews, in particular from certain political ideologies (a number of other definitions do not). Relying on the findings, the paper develops two structural conceptual models which serve to describe religious and non-religious belief systems. Further, the definition and the conceptual models allow to establish a clear criterion to distinguish pivotal structural differences between religious and non-religious belief systems. The criterion is based on the concept of two kinds of rationality: first-level and second-level rationalities. These will demonstrate to what degree religion can be a rational enterprise, and what role logic can play in it. The result is a clear-cut line in the structures of religious and certain consistent nonreligious belief systems (e.g. a scientific theory).Keywords Logic · Worldviews · Two levels of rationality · Religion and science · Belief systems · Definition of religion How can a religious person be rational, applying rules of logic, and at the same time irrational, making decisions based on faith? Are religious and non-religious belief systems structurally comparable, and if so, to what extent?
The paper presents an analysis of the anumāna chapter of Jayarāśi's Tattvôpaplava-siṁha and the nature of his criticism levelled against the anumāna model. The results of the analysis force us to revise our understanding of Jayarāśi Bhat˙ṫa as a sceptic. Instead, he emerges as a highly critical (materialist) philosopher. In addition, the nature of Jayarāśi's criticism of the anumāna model allow us to conclude that anumāna should not be equated with inference, but rather is its limited subset, and may at best be rendered as 'disputational inference', 'debational inference' or even 'dialogical inference'. Jayarāśi applies a range of logical laws which clearly represent patterns of what can be classified as a priori reasoning (if we grant that there could be a priori justification for our knowledge at all) and analytical justifications for knowledge, which were traditionally not reckoned sound. Against the backdrop of Jayarāśi's criticism of anumāna, the paper also attempts to provide an explanation to why Indian philosophy and logic did not develop any concept of proper symbols and variables.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
