He presented very interesting and important plans of establishing the Scientific Society, the main goal of which would be the dissemination of knowledge.The preserved letters show the astronomer of Vilnius as a broad-minded person, a curious scholar, and a capable organiser of research. The correspondence also reveals the bonds of friendship between Naruszewicz and Poczobut.This epistolary legacy and its discussion enrich our knowledge of the culture of the Age of Enlightenment in the Polish-Lithuanian Commonwealth.
