Question

For much of the twentieth century, the dominant historiographical model regarding the emergence of modern science positioned the seventeenth century as a period of radical, unprecedented rupture. Scholars in this tradition, most notably Alexandre Koyré, argued that the intellectual achievements of figures like Galileo and Newton represented a fundamental discontinuity with the past. According to this narrative, the "Scientific Revolution" required the wholesale destruction of the Aristotelian cosmos and the establishment of a completely novel mathematical physics. Medieval natural philosophy was characterized as conceptually sterile, overly deferent to ancient authority, and structurally incapable of producing the quantitative methodologies that define modern scientific inquiry.

However, this paradigm of abrupt intellectual rupture was challenged by the emergence of the "Continuity Thesis," a framework originally pioneered by Pierre Duhem. Proponents of the Continuity Thesis argue that the ostensibly revolutionary concepts of the seventeenth century were, in fact, deeply rooted in the analytical traditions of the late Middle Ages. Rather than springing into existence ex nihilo, the foundational principles of classical mechanics were built upon centuries of incremental scholastic refinement. From this perspective, the scientific achievements of the early modern period are better understood as the culmination of an ongoing evolutionary process rather than a sudden conceptual mutation.

The evolution of the concept of inertia serves as a primary illustration of this historiographical revision. Traditional narratives often credit Galileo with the spontaneous invention of inertial physics. Yet, Continuity theorists point to the fourteenth-century Parisian scholar Jean Buridan, whose "impetus theory" sought to explain the continued motion of projectiles. Buridan proposed that a mover imparts a motive force—an impetus—to a projectile, which sustains its motion until overcome by air resistance and gravity. While qualitatively different from the strictly conserved inertial state formalized by Newton, Buridan’s impetus provided a crucial conceptual bridge. It dismantled the Aristotelian requirement for a continuous external mover and established a theoretical scaffolding that later mathematicians would adapt and refine into the modern laws of motion.

While the Continuity Thesis provides a necessary corrective to the more exaggerated claims of the rupture model, extending its logic too far risks obscuring the genuinely novel methodological synthesis achieved in the seventeenth century. The late medieval scholars certainly developed sophisticated logical critiques of Aristotelian physics and generated conceptual tools that proved invaluable to their successors. However, these scholastic innovations remained largely speculative and isolated from systematic empirical verification. The true watershed of the Scientific Revolution was not the sheer invention of new concepts, but rather the unprecedented integration of highly abstracted mathematical modeling with rigorous experimental testing—a systematic methodology that the medieval tradition never fully realized.
