Moral Theology: Its Method and Masters

The Positions in Charts

Drawn from the authors' own words; every quotation links to its place.

The virtues: Faith · Hope · Charity · Prudence · Justice · Fortitude · Temperance · In charts

These charts count the points set out on the pages of the positions compared: 404 points on which our authors part ways about the seven virtues. They measure how the authors divide where they dispute, not how often they agree in all their teaching, which is far more often. An author counts on a point when he is placed on one side of it; St. Alphonsus counts as our authors report him, and not where two of them report him on different sides. Pairs placed together on fewer than 8 points are left uncounted.

How Often Two Authors Answer Alike

For every two of the authors placed on at least 50 points: of the points both answer, the share they answer the same way. Blue, mostly alike; red, mostly not; gray, about half and half. Hover over a square for the count. The order is the order of the positions pages: St. Thomas and St. Alphonsus, then the Thomists (Billuart, Concina, Prümmer, Merkelbach, McHugh-Callan), the Franciscan (Bontempi), the Redemptorists (Marc, Wouters) and the Jesuits (Noldin, Sabetti-Barrett, Vermeersch).

With St. Alphonsus

Of the points where our authors report St. Alphonsus's opinion, how often each author takes his side. His Theologia moralis is not yet in this library, so these are reports, chiefly Marc's, Wouters's, Prümmer's, Noldin's and Sabetti-Barrett's.

How Settled Each Virtue's Questions Are

Each virtue's disputed points, sorted by how our authors divide on them (St. Thomas and St. Alphonsus apart). A point where all our authors who answer it agree is a dispute still: St. Thomas or St. Alphonsus stands apart, or the fuller entry records a dissent outside this library or a difference of reason.

  • All who answer it agree
  • Two-thirds or more on one side
  • A smaller majority
  • Evenly divided
  • Only one author answers it

Our Authors Through Time

Each author's life, and a dot for the year of each of his works in this library, the year of the edition we hold: a filled dot for one published in his lifetime, a ring for one published after his death. Two dates mark the changes our authors most often reckon with.
