This article examines E. Sergio’s studies on the concept of sensus communis as developed by Giambattista Vico, highlighting its historical and philosophical significance. The analysis positions Vico as a pivotal figure bridging medieval and modern thought: he inherits the intellectual legacy of the past while reinterpreting its core elements through a distinctly modern sensibility. Within this framework, sensus communis emerges as a key concept for understanding human social action—a perspective that, drawing from Aristotle and Thomas Aquinas (whose approaches modernity often rejects), finds its fullest expression in Vico’s system. By privileging language as a primary mode of communication, Vico is shown to transcend the Hobbesian conception of human nature specifically through the lens of sensus communis.
