Abstract: | I endeavour in this article to present Ibn Taymiyya's theory of nominal definition as an alternative to logical definition. Ibn Taymiyya argues that nominal definition is based on concrete principles that are subject to experiment. Furthermore, the function of definition is akin to the ‘name’ because it aims at distinguishing any one object from others but not at reaching the entity of things. Nominal definition aims to define the name or the named, and this aim can be achieved by translation or by interpretation. Translation is the movement from one name to another or from one named object to another. Interpretation is movement from a name to a named object or from a named object to a name. |
