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.

Thomas Aquinas Summa Theologiae - Whether Love Is In God - Sadler's Lectures

Heloise and Abelard - Letter 3 - Love, Virtue, Duty, and God - Sadler's Lectures
This lecture discusses key ideas from the sequence of letters between two great Medieval intellectuals, lovers, and religious Heloise D'Argenteuil and Peter Abelard
It focuses specifically on the third letter, which is by Abelard. It discusses Heloise's proposal that although they have taken monastic vows, they can rightly enjoy some married life together through writing letters to each other, and Abelard's rejection of that suggestion. He tell her that they both must turn to God and make Christian perfection their goal, even if that means leaving their amorous relationship behind, and he tells her that by his own confessions, he intends to change her love into contempt or hatred for him.

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.

Seneca, Letter 99 - Consolation For Loss Of A Child - Sadler's Lectures
This lecture discusses key ideas from the ancient Stoic philosopher Seneca's Letters, this one looking at Letter 99
In this letter, after a brief introductory paragraph, Seneca reproduces a letter sent to a different correspondent Marullus when he had lost a young child. Although Seneca says that his goal is not to console but rather to offer criticism, he in effect does both of these, offering a number of considerations that can prove helpful to a person who is grieving the loss of a loved one.
