Responses Proper to Listening to Music and the Experience of Ecstasy is the eighteen chapter of the Revival of the Religious Sciences (Ihya' 'ulum al-din), a monumental work of classical Islam written by the renowned theologian-mystic Abu Hamid al-Ghazali (d. 1111). This chapter of the Revival deals with the controversial topic of music. In the Islamic legal tradition, there is disagreement as to whether or not performing and listening to music is lawful, even more, whether music might be used as a path to ecstasy. Basing himself on the Qur'an, hadith, the first generations of Muslims and the mystical tradition, Ghazali presents the arguments both for and against listening to music. Ghazali's own position is that music in itself is permissible, though under certain circumstances it can be unlawful or undesirable. Ghazali emphasises awareness of the omnipresence of God in creation and the importance of using the mind, hearing and sight to bring one closer to God. In Responses Proper to Listening to Music and the Experience of Ecstasy he gives lyrical expression to his love of poetry and music, and their legitimate place not only in human celebrations, but in divine worship and as aids on the path to gnosis and ecstasy. All such responses he sees exemplified in the life of the Prophet with his family. This volume also includes a translation of Imam Ghazali's own Introduction to the Revival of the Religious Sciences, which gives the reasons that caused him to write the work, the structure of the whole of the Revival and which places each of the chapters in the context of the others.
