Linkage: Feser’s Negative Mysterian Defense of the Trinity (Dale)

At his self-titled blog Edward Feser, the Catholic philosopher & popular author mounts a negative mysterian defense of the Trinity.
It’s worth a read. In my view, most of it is perfectly reasonable, but it goes wrong where he claims that the teaching of Christ as recording in the New Testament logically implies the creedal formulas [...]

Linkage: Vallicella and Lukas on Supposita (Dale)

Thanks to Vlastimil Vohánka for referring us to this discussion between Maverick Philosopher Bill Vallicella and Dr. Lukas Novak of Charles University, Prague.
As I understand it, a suppositum is supposed to be an ultimate subject of characteristics / properties, as distinct from non-ultimate subjects. My individual human nature is supposed to be suppositum, but Christ’s [...]

Richard of St. Victor’s De Trinitate, Ch. 20 (Dale)

As Joseph explained in his last post, in his On the Trinity, Richard of St. Victor asserts the superiority of “shared love” (Latin: condilectus). He holds that it is superior to other loves in value and in the pleasure it involves. He’s imagining something like my chart on the left.
Look at the bottom case, and [...]

Richard of St. Victor’s De Trinitate, Ch.15 (Joseph)

So we’re done with ch.14. Now on to ch.15. Here’s a paraphrase of his argument:

With divine persons, the perfection of one requires another, and so the perfection of a pair requires union with a third. Each such person is perfectly benevolent and so shares his perfection with the other. But if each is perfectly benevolent, [...]

Linkage: What Randal wants for Christmas (Dale)

Philosophical theologian Randal Rauser has been blogging as the Tentative Apologist. This year, for Christmas, he says he’s hoping for “a coherent account of the incarnation“. In other words, he wants a way of understanding the incarnation doctrine which is apparently consistent. Will he get it? Word has it that the elves are working overtime [...]

Richard of St. Victor’s De Trinitate Ch.14 (Joseph)

We now turn to Richard’s De Trinitate Book 3, Chapters 14-19
Here’s my formulation of the first part of ch.14:
Suppose there’s at least one divine person: P.
Then (1) P is so benevolent that he wants to have no good that he does not want to share.
And (2) P is so powerful that everything is possible for [...]

Richard of St. Victor 11 – Response to the Argument From Love Thus Far (Scott)

In three of the last four posts (Rick St. Vick 6, 7, 9, 10) I surveyed some of Richard of St. Victor’s arguments for why there must be at least three divine persons. (We’ve yet to see an argument for there aren’t more than three persons.) Here I’d like to respond to these, and to [...]

Richard of St. Victor 10 – Perfect Happiness Requires Perfect Love (Scott)

After his initial argument from perfect love for a Trinity of persons, Richard tries to support it by a brief argument from perfect happiness. Here I wish to summarize what I take to be this confirming argument from the plenitude of happiness. [Keep in mind that ‘plenitude’ has that particular meaning of a property of [...]

Richard of St. Victor 9 – Perfect Love Requires Three Persons (Scott)

In this post I’d like to focus on Richard’s initial argument for why God must be a Trinity of persons. Thus far in his argument he has argued for two divine persons, and now adds a further line of argument to show that God is in fact a Trinity and not a Binity of persons. [...]

“Trinity” @ the Stanford Encyclopedia of Philosophy (Dale)

Little known fact: overwork causes one’s neck to become invisible!
After an embarrassing amount of time, I’ve finally finished my encyclopedia entry on the Trinity for the Stanford Encyclopedia of Philosophy (as well as lengthy supplementary documents on the history of Trinity doctrines, Judaic and Islamic objections, and unitarianism).
Since I can’t thank them in the entry, [...]

Richard of St. Victor 8 – A Proposed Constitutional Trinitarian Taxonomy (Scott)

Richard of St. Victor is well known for talking about love, and how awesome it is. It might surprise a few people who have only read the popular English translation of Book 3 (the love/ethics? book) that On the Trinity contains six books. The English translation has brought attention to what some contemporary (continental-esque) philosophers [...]

Richard of St. Victor 7 – The Same Divine Substance (Scott)

Up to this point in Book 3 Richard has told us several things about love (caritas). We have wondered at his saying there isn’t a perfectly good person if he doesn’t love. We have sorted through some necessary conditions for love such that we wonder whether a perfectly good person p must love another person [...]

Richard of St. Victor 6 – Supreme Love Only Among Equals, Again (Scott)

In De Trinitate Book 3.7 Richard summarizes some of what comes beforehand. We have learned that supreme goodness requires supreme love (i.e. supreme love is a necessary condition for supreme goodness), and that supreme love requires more than one person. If supreme love were only self-love, then the total state of affairs “one divine person [...]

Richard of St. Victor 5 – Evaluation of the argument thus far (JT)

In the last three posts, I explained Richard’s argument for why there must be two distinct persons who charitably love each other. Here I want to raise some objections to three of Richard’s claims.

Richard of St. Victor 4 – Charity is shared by equals (JT)

STAGE 3. Next, Richard tries to establish that God can only charitably love an equal. He introduces this idea by raising the following objection: if God must direct his charitable love at a distinct person, then why couldn’t he direct his charitable love at a created person? That would satisfy T5 from the last post, [...]

Richard of St. Victor 3 – Perfect charity must be directed at another person (JT)

STAGE 2. In this stage, Richard tries to show that perfect charity must be directed at another person. Here’s the quotation:
‘no one is properly said to have charity on the basis of his own private love of himself. And so it is necessary for love to be directed toward another for it to be charity’.

Richard of St. Victor 2 – God’s goodness requires charity (JT)

STAGE 1. In this stage, Richard wants to show that God’s perfect goodness somehow requires that God is perfectly charitable. I say ‘somehow requires’ because the logical relation here is not clear. Richard is saying ‘God’s goodness _____ perfect charity’, but what fills in the blank? Is it ‘entails’, ‘presupposes’, or some other logical relation?
Here’s [...]

Richard of St. Victor 1 — Introduction (JT)

Richard of St. Victor is well known for his argument that perfect love must be shared between three persons, and since God’s love is perfect, there must be three persons in God. Richard presents this argument in Book 3 of his De Trinitate, and that’s what we’ll be looking at in this series of posts.

Arius and Athanasius, part 11 – General questions about divine production (JT)

In this series of posts, I’ve been discussing the view of Arius that the Son is created from nothing, and the view of Athanasius that the Father begets the Son. All of this illustrates two basic issues that any classical account of the Trinity has to face when it tries to explain how one divine [...]

Arius and Athanasius, part 10 – The Father and Son can’t share all their properties (JT)

Last time, I explained that Athanasius has not made it clear how the Son ‘inherits’ divine properties from the Father. Yet even if Athanasius could explain how the Son ‘inherits’ properties from the Father, there’s still another problem. Like Arius, Athanasius believes that the Father is simple, and so anything ‘in’ the Father is, strictly [...]
