An Analytic-Comparative Study of the Theory of the Simplicity of Derivation in Sayyid Sanad and Mulla Sadra

In some disciplines such as logic, usul al-fiqh, and philosophy, there are two main theories regarding the derivative and the truth of its component parts: conceptual superimposition of the derivative and its simplicity. Each of these two theories provides a different interpretation of philosophical problems. Hence, similar to other thinkers in the field of religious sciences, philosophers have exercised extreme care in choosing one of these stances. Among the related approaches, Sayyid Sanad has provided a different view and believes in the limitedness of the derivative. He maintains that this concept potentially (not actually) consists of three components. A study of Mulla Sadra’s views indicates that the theory which has been rejected in the name of Sayyid Sanad in Mulla Sadra’s works is not compatible with what we find in the words of Sayyid Sanad himself. Mulla Sadra is mainly interested in the view of Sayyid Sanad’s rival, that is, Muhaqqiq Dawani.
