Studying Mollasadra’s Viewpoint on Authority and Cause and Effect Necessity

Authority and its relationship with the philosophical principle of cause and effect necessity is known as one of the most essential and challenging topical issues among philosophers and Islamic orators. Each of the scholars in the field has tried to express his own definition of the issue regarding his own line of thought.The present study deals with the problem regarding a library study data collection and using a descriptive-analytic method and it is fundamental considering the aim of the study. This research intends to investigate the viewpoints of Sadr-al-Motaallehin Shirazi regarding authority and cause and effect principle necessity. After probes of works and writings of Sadra, it was concluded that Sadra’s ideas were rooted in philosophical mysticism principles and he tried to represent authority compatible with cause and effect principle necessity. Believing in such a principle not only does not deny authority but also approves it. It accepts the principle that there isn’t any obligation but one can choose from among different options and this represents the borderline between responsibility and authority clearly and considers authority to be synonymous with being a follower.
