This version of Aquinas’ Summa contra Gentiles contains the annotations of Joseph
Rickaby, early 20th century Jesuit priest and philosopher, alongside the main text.
Aquinas meant his treatise to serve as an apologetics handbook for missionaries
and philosophers defending the Christian faith against those outside of or hostile to
Christianity. The style and content of Aquinas’ arguments were particularly relevant to
his time. The major religious communities in close proximity to the Christian West—
Jewish and Islamic—had developed their various theological views using borrowed terms
and ideas from Aristotelian philosophy just as Aquinas himself had. Readers have found
Rickaby’s annotations helpful, as his comments strive to enrich the understanding of
others rather than promote a particular philosophical agenda.
