Thomas Aquinas Summa Theologiae - God's Love For Other Things - Sadler's Lectures

This lecture discusses key ideas from the medieval Christian philosopher and theologian Thomas Aquinas' Summa Theologiae, 1st part, question 20, "God's Love", and examines his discussion in article 2, which examines the question whether God loves things other than God. Thomas considers four main lines of reasoning that would say that God either doesn't love other things or only loves some other things but not others. He then clarifies that God wills good to all things that exist, giving them the very being and goodness that they possess, so God loves all things insofar as they are. This doesn't mean that he loves all things to the same extent or in the same ways.

Seneca, Letter 109 - Fellowship And Wise People - Sadler's Lectures

This lecture discusses key ideas from the ancient Stoic philosopher Seneca's Letters, this one looking at Letter 109 It focuses specifically on whether or not a wise person, according to the Stoics, would want or need to be involved with other people, particularly other wise people, to which his answer (perhaps surprisingly to some) is yes. He provides some reasonings for the position he articulates on this, including how the wise person, despite in a strict sense not needing anything or anyone else, will nevertheless desire to share their life with others, and will also benefit from the advice and fellowship of other wise people.
