Classification of sciences, in addition to ease of scientific tasks, makes a kind of intellectual discipline for researcher and define the amount and level of each science and helps describing the geometry of science in Islamic civilization, that is why in the Islam scientific community, the primary emphasis is always on this principle. ‘Jame ul - olum’ written by Fakhr ud - Din Razi,one of the Ash’arit speakers in 6th- century A.H., has paid attention to classification of sciences and presented a new attitude toward science, through debating subsidiary branches of sciences as independent sciences in his classification, meanwhile, his classification became the pattern of many other scientists after him. Shams ul - Din Amoli who was a Shiite instructor in 8th-century A.H., focused on classification of sciences in ‘Nafayes ul - Fonun’ book. As Fakhr ud- Din Razi, he raised new sciences in his classification and through eliminating traditional classification of sciences rendered a new approach to the history of science. Above mentioned classifications have similar and dissimilar characteristics, both in kind of attitudes toward science and classification of sciences. During this review, along with comparison between the two mentioned classifications, the impact and importance of intellectual- verbal perspectives and historical conditions of these scientists in classification of sciences and presenting different classifications in history of science will be expressed.
