This work is blend of history and philosophy. Its main objective is to place the history of science and philosophy in Islamic Civilisation into a proper historical perspective. Attempting to provide a framework of history, this books aims at developing tools by which the history of Islamic science and philosophy can be examined and identified. To adequately carry out of task, the author argues that we need an epistemology of science that must be extracted from history. In short, this piece aspires to re-establish the historical framework of Islamic science tradition. ‘Science’ and scientific here are not to be understood exclusively as referring to empirical or experimental disciplines dealing with the physical phenomena, but rather, more inclusively they portray a systematic and formulated knowledge of a specified subject. The work is original in sense that it offers a new framework for history of science in Islamic civilisation, which is interestingly applicable to other civilisations as well.
