Religions use linguistic and non-linguistic codes of meaning to express their contents: natural tongues, music, sculpture, poetry, rituals, practices... Also, religions provide the semantic context and the rules to produce, validate, and interpret their expressions: as such, religions can be considered languages. The Sophia Special Issue ‘Religions and Languages: A Polyphony of Faiths’ explores the multifaceted relationships of world religions with languages broadly construed, intended as other religious codes, natural tongues, artistic forms, digital media, and even science. Do natural languages (...) modify themselves in order to convey a divine message? How do artistic means of expression accommodate religious contents? What are the aspects of interaction between religions, technological advances, and scientific methods? The five contributions in this issue offer innovative, compelling, and engaging perspectives regarding this complex and fascinating issue. (shrink)
