• This thesis is the result of an investigative work on the formulations and defense ofreligious tolerance in the Catholic Enlightenment of Portugal, to a greater extent, butalso touching on some transits with Brazil. It is assumed that the secularization processthrough which the Iberian kingdom passed, during the eighteenth century, was afundamental element of articulation of previous strands of defense of greater religioustolerance with debates pertinent to the Enlightenment. In this way, this religioustolerance was the product of quite complex syntheses, presented in typical spaces andsociabilities of the Seventeenth and were, in some way, agents of change in a realitymarked by vigilance in matters of opinion and religion. Such formulations of religioustolerance were part of the more radical or more moderate forms of tension inherent inthe struggle for a “religious field” understood here as legitimate access to the so-called
    “assets of salvation” in Pierre Bourdieu’s terminology, which encompass from recognized and authorized interpretations of the Scriptures to religious rites and precepts, thus forming a fundamental critical substrate for thinking about thedissolution of some basic institutions of the Ancient Regime.
