In this article, through the discourse analysis of Ebrahim Beg's itinerary written by Zeyn al-Abedin Maraghei, the idea of progress was examined in the literature of the constitutional era. It was shown how efficacy of the progress discourse of the law caused the society with regard to "existence of equality in law" moves towards the ideal society and passing this route requires removing specified defects in the nation and the government at the same time, thereby at the end of the route a developed homeland will be emerged by establishing a bilateral relationship based on empathy and trust between the government and the nation. The idea of progress was examined in the four aspects of rationalism, universalism, the role of the government and the contrast between what it is and what it should be, and it was found that Maraghei believes in giving priority to wisdom, a dialogue for compiling and implementing of law as the driving force of a society that has lagged behind civilized societies, especially Japan, and the main reason for this retrogression is the influential and self-seeking ministers and dignitaries. To him, progress is achieved through the weakening of profit seekers and self-interested court and non-court people as what it is and the strengthening and increasing the ones who care for the country and the ones who love their homeland from bottom of their heart and seek the honor of the country as it should be.
