History of Political Thought in Iran — Part 5: The Life and Times of Nasir al-Din Tusi

The seminar begins with a larger problem in Iranian intellectual history: Javad Tabatabai’s thesis concerning the decline of practical philosophy. In this account, by the time Iran encountered modernity in a decisive way, much of the conceptual vitality of its older tradition had been lost and political philosophy had ceased to respond adequately to historical transformation. Nasir al-Din Tusi becomes one important point in this shift: a thinker who gathered earlier traditions together but may also have helped turn practical wisdom into something increasingly detached from historical change. The seminar takes this criticism seriously while testing it against Tusi’s life in an age of collapse.

Tusi lived while Iranian political and scholarly institutions were under severe pressure. After study in Khurasan and wider intellectual travel, he spent many years within the Ismaili fortresses and wrote the Nasirean Ethics in that context. The seminar emphasizes its three classical domains of practical wisdom: cultivation of the self, management of the household, and governance of the city. The sequence matters. Politics begins with a person capable of self-discipline, judgment, and orientation toward truth; governing is not reducible to legal command or the technique of power.

Philosophically, Tusi is portrayed as an adhesive force among traditions being torn apart. He defended Peripatetic philosophy against Fakhr al-Din al-Razi’s attacks, worked within Avicennian thought, remained attentive to Illuminationist wisdom, and attempted to preserve reason, religion, and philosophical inheritance within one field. This synthetic character is precisely where disagreement arises. Was he a reviver of philosophy or a compiler whose synthesis closed the space for innovation? The seminar does not resolve the question simply; it argues that any judgment of his originality must take the emergency of his historical situation seriously.

The larger political controversy concerns his relationship with Hulagu. After the fall of the Ismaili fortresses, Tusi worked with the Mongol ruler, which has led to both accusations of collaboration and praise for rescuing scholarship. The seminar resists the binary. Faced with a military power that could not simply be repelled, Tusi used his position to reduce bloodshed, preserve books, recruit scholars, and establish the Maragheh observatory as a major intellectual centre connected to researchers from different regions.

The concluding question concerns what intellectual action can mean during civilizational breakdown. Is preservation sufficient in a moment of destruction, or can the very act of preservation harden later into repetition? Tusi’s life contains both possibilities. He saved traditions that might otherwise have disappeared, but Tabatabai’s question remains: did that tradition later regenerate the conceptual capacity to respond to new historical conditions? Tusi thus appears as a thinker of a threshold—someone who protected reason and scholarship amid devastation without being able, by himself, to solve the later crisis of Iranian political philosophy.
