That a man’s fortunes and fame are linked to a certain doctrine or controversy may be an accident of environment. Berengar chose to adduce and partly follow the teachings of Eriugena, whose fame was great, but whose orthodoxy was tainted. The nature of the Eucharist leant itself to dispute, and from the time of Ratramnus, Radbertus, and Eriugena, it was common for theologians to try their hand on it, if only in order to demonstrate their adherence to the extreme doctrines accepted by the Church. These were not the doctrines of Eriugena, nor were they held by Berengar, who would not bring himself to admit an absolute substantial change in the bread and wine. Possibly his convictions were less irrational than the dominant doctrine. Yet he appears to have asserted them, not because he had a clearer mind than others, but by reason of his more self-assertive and combative temperament. He was not an original thinker, but a controversial and turgid reasoner, who naturally enough was forced into all kinds of tergiversation in order to escape condemnation as a heretic. His self-assertiveness settled on the most obvious theological dispute of the time, and his self-esteem maintained the superiority of his own reason over the authorities adduced by his adversaries. Of course he never impugned the authority of Scripture, but relied on it to substantiate his views, merely asserting that a reasonable interpretation was better than a foolish one. Throughout the controversy, one may observe that Berengar’s understanding of fact kept somewhat closer than that of his opponents’ to the tangible realities of sense. But a difference of intellectual temperament lay at the bottom of his dissent; and had not the Eucharist presented itself as the readiest topic of dispute, he would doubtless have fallen upon some other question. As it was, his arguments gained adherents, the dominant view being repellent to independent minds. Still, it won the day, and Berengar was condemned by more than one council, and forced into all manner of equivocal retractions, by which at least he saved his life, and died in extreme old age. It may be that a larger relative import attributed by Berengar and also Roscellin to the tangibilities of sense-perception, led the latter at the close of the century to put forth views on the nature of universals which have given him a shadowy repute as the father of nominalism. The Eucharistic controversy pertained primarily to Christian dogmatics. That regarding universals, or general ideas, pertains to philosophy, and, from the standpoint of formal logic, lies at the foundations of consistent thinking. So closely does it make part of the development of scholasticism, that its discussion had best be postponed; merely assuming for the present that Roscellin’s thinking upon the topic to which his name is attached was not superior in method and analysis to Berengar’s upon the Eucharist.
