The Church’s victory in the “Investiture Controversy,” throwing off the domination achieved over it by secular powers following the death of Charlemagne, made it the first domain to successfully assert the right to manage its activities in accord with its own principles. But victory was only partial, leaving spiritual and secular powers facing each other across a field of constantly shifting relationships, giving heterodoxy more room to survive than elsewhere. An early example was the contrast between European universities, established as associations of teachers and students formed to assert autonomy from town authorities, and Islamic madrasas subject to direction by their elite patrons. When the corpus of Aristotelian texts became available, first in Arabic and later in Latin, it was first greeted with enthusiasm by readers of both, followed by suspicion because Greek materialism posed threats to religious doctrines. In Muslim lands, this led to a widespread rejection of philosophical inquiry as a path to truth; in Europe, attempts to impose similar restrictions failed, because university faculties resisted the claims of churchly conservatives to limit what could be taught. In this situation, scholastic speculation generated radical ideas about cosmology and physics, foreshadowing the break with traditional cosmology two centuries later.

Although liberty has been valued in various ways in many times and places, only in Europe did it become a central preoccupation before the nineteenth century, and a subject of widespread public reflection. Appeals to liberty and concerns about it found expression in two idioms: a singular one that harked back to Rome and Greece, and regarded liberty as universal or innate; and a plural one associated with the overlapping jurisdictions of ‘feudal’ society that saw liberty as an assemblage of separate rights or privileges (often taken as synonyms), attributed sometimes to custom and sometimes to higher authorities that granted them. Although distinct, the two languages were seldom seen as in tension before the eighteenth century. The chapter examines their relations in different contexts and concludes by noting that the very pervasiveness of claims to enjoy, embody, or represent liberty led to a recognition of how easily invocations of it could become rhetorical tools to justify control over others, leading to Machiavelli’s incisive reflections on the dialectical relations between liberty and domination.
