Summa Theologica, Part II-II (Secunda Secundae)
 Translated by Fathers of the English Dominican Province

by Aquinas Thomas

"Summa Theologica, Part II-II (Secunda Secundae)" by Saint Aquinas Thomas is a theological work written in the 13th century. This section forms part of Thomas Aquinas's masterwork presenting Catholic theology through systematic reasoning. It examines morality in particular detail, exploring individual virtues and vices through 189 questions and 917 articles. Drawing from Christian, Islamic, Jewish, and classical sources, Aquinas employs a distinctive format of objections, counter-arguments, and replies to investigate ethical questions. This portion remains foundational for theological and philosophical study across Christian traditions.
