The Art of Tetman Callis

“Every artificer, indeed, aims to produce a work that is beautiful, useful, and enduring, and only when it possesses these three qualities is the work highly valued and acceptable. Corresponding to the above-mentioned qualities, in the pattern of life there must be found three elements: ‘knowledge, will, and unaltering and persevering toil’. Knowledge renders the work beautiful; the will renders it useful; perseverance renders it lasting.” – John of Fidanza, Bonaventure, Retracing the Arts to Theology (trans. Healy; emphases in original)
