 Since all knowledge in every art is “conceptualization” (tasawwur) of the meanings of the art and it is “assent” (tasdiq) to what is conceptualized, everyone who learns an art logically (bi-qawl), when he learns this science, he intends to conceptualize its meanings (maʻná) and to give assent to what he has conceptualized, and no one can acquire any science unless he has the two (IB-taaliq: 64).
