Hispanic specialists in the Alphonsine work have studied the distinction between ‘natura’ and ‘nature’ of the Partidas. The conclusions of these analyzes affirm that this distinction is born from a semantic displacement that is situated in a plane of legal-social relationships, within a naturalistic model in the Alphonsine political project that shows a Christian Aristotelian reading. The present paper does not differ from these conclusions, but we believe that it is necessary to modulate this naturalistic model from broader metaphysical conceptualizations (...) that better explain what that Christian Aristotelianism consists of. We will try to reinforce these theses from assessments that have the multidisciplinary nature present in the Alphonsine scriptorium as a backdrop. We present the possible influence of the philosophical schemes of the First Franciscan Scholasticism in this distinction of the terms ‘nature’ and ‘nature’. (shrink)
