Lorenzo Valla on the Problem of Speaking about the Trinity Charles Trinkaus Lorenzo Valla was a major Renaissance humanist critic of scholasticism, and a proponent of empirical and language-based thought. He also ventured into the field of theology with his humanistic preconceptions that not ancient philosophy but the literary arts and philology should provide the proper model for its study. Salvatore Camporeale in his major studies of Valla, and in a recent notable article comparing the humanistic method of theologizing of Valla with the scholastic method of Thomas Aquinas, established the major features of this new mode of theologizing as based on Biblical philology and study of the Church Fathers. 1 This was taken up by Erasmus and given its fully developed form. 2 Valla was rash enough to apply his methodology to the central Christian doctrine of the Trinity, not without some disastrous results in his first effort in the 1439 redaction of his Repastinatio dialectice et philosophie, but with greater doctrinal acceptability in his later revised versions of 1448 and 1452. 3 Like all theological mysteries, the Trinity defied both ordinary human language and the most rudimentary rules of thought, i.e., grammar, logic, and “common sense.” 4 Hence there was a [End Page 27] great challenge and a real danger of falling into error in talking about the Trinity either to establish its true “nature,” or to defend it against criticism. Valla’s efforts may be considered likely paradigms of some of the ways language study played a role in unraveling one of the Christian religion’s central mysteries. It was one of Lorenzo Valla’s main convictions that the theology and religious and moral thought of his own age (namely Aristotelian scholasticism) should be purged of philosophy, which he regarded as a seedbed of heresy. Yet he himself, though a rhetorician, was not entirely pure of philosophy...just as elements of philosophical thought remained as indispensable ingredients of the rhetorical teachings of Cicero and Quintilian. Thus Valla, following them, especially Quintilian, found it necessary to retain some simplified elements of systematic thought in his primordia of linguistic theory. Nevertheless, he intended to demonstrate that a more satisfactory description of the Trinity could be attained by adhering to these rules of language than that arrived at by the scholastics seeking to affirm it by metaphysical principles. I: The Repastinatio of 1439 Valla in his proem to the 1439 redaction of the Repastinatio stresses the libertas a philosopher should have to think and express his own thoughts and protests the compulsion to think in Aristotelian modes manifested by scholastic philosophers: Why therefore should we fear to contradict this man, especially while following the approved custom of freely stating what we believe? Certainly they treat themselves badly who commit themselves to some sect in which it is necessary to praise everything of the one they follow, whatever it is. We have insisted on that liberty in other books and will hold to it in these. 5 In keeping with these sentiments Valla in this first redaction boldly sets forth his own views. For reasons which will be seen he becomes more careful to refute his opponents and justify his own views in the later two redactions. In this first redaction he begins by setting forth his reduction of the ten Aristotelian/Porphyrian/Boethian categories to three “elements,” using a term found in Quintilian. These are “substance,” “quality” and “action.” He follows this up by reducing the so-called six transcendentals to the one, multi-meaninged term res, or “thing,” which is that about which one is talking, or the subject that can comprise substance, quality and action. 6 [End Page 28] Because the res or “thing” is never substance only, since substance can never be perceived except by means of its qualities or actions which are manifest to the perceiver, Valla proposes a new term for the combination of substance, quality and action: “consubstance.” “There are two species of [consubstance],” he writes, “ ‘soul’ and ‘body.’ A third which is composed of both of these may be added, which is ‘animal.’” 7 Just before introducing the term “consubstance” for things in their combination of the three elements, and without...
