“ At Deventer, where the best traditions of the 14th century mysticism were still cultivated, Wessel imbibed that earnest devotional mysticism which was the basis of his theology and which drew him irresistibly, after a busy life, to spend his last days among the Friends of God in the Low Countries. From Dcventer he went to the Dominican school at Cologne to be taught the Thomist theology, and came in contact with humanism. ”

“ As old age approached he came to have a growing dislike to the wordy theological strife which surrounded him, and turned away from that university discipline, "non studia sacrarum literarum sed studio rum commixtae corruption es." ”
