Are the Souls of Brutes Subsistent?

Aquinas says No but his argument is inconclusive.

Substack latest.

Reader Zacary writes,

I am just a layman who likes studying Aristotelian and Thomistic philosophy, and recently I haven’t been studying the issue of animals in the afterlife. I stumbled across your post from many, many years ago (all the way back in 2009!) that was about the unity of consciousness argument and the subsistence of animal souls. 
Thank you for writing, Zacary.  That post from 2009 left a lot to be desired, so I rewrote it almost completely and published the result over at Substack. I have no time now to respond  to the rest of what you wrote, but if you read the Substack entry and have questions or objections I will try to answer them here.

Four Attitudes Toward Embodiment

Am I ineluctably trapped in a dying animal? Is embodiment an axiologically negative state of affairs or is it an axiologically positive one?  Here are four possible attitudes toward having a material body. They may be loosely associated, respectively, with the names Plato, Aristotle, Aquinas, Benatar.

a) To exist is good, but it would be better to exist without a gross material body subject to decay and dissolution. The body is an impediment, a vehicle for sublunary roads that it would be better not to have to travel.  I am neither identical to my body, nor dependent on it for my existence; I am a soul temporarily incarcerated in a body from which I will be released upon death. I have fallen from a topos ouranios into a spatiotemporal matrix and meat grinder extrication from which is both possible and desirable.

b) To exist is good, but a gross material body is necessary to exist as a conscious and self-conscious being, whence it follows that embodiment is at least instrumentally  good. I am not (identically) a soul; I am a soul-body composite, both components of which are necessary to exist at all.  

c) To exist is good, but only with a 'resurrected' and perfected body supplied by a divine being that needs no body to exist.

d) To exist is not good because possible only with a gross body.  (See my Benatar category.)

De Anima

David K. writes,

I need some help.  I have been exploring the concept of the 'soul' over the last few months. I've meant it to be a fairly wide open review.  I have 'rounded up the usual suspects' philosophically and worked my way through a great deal of the biomedical writings.  Presently, I am in the middle of two works:  The Soul of the Embryo by David Albert Jones and Soul Machine by George Makari.  I am looking for a contemporary philosophical treatment of the topic.  I have searched the categories on both your blogs but wonder if there is a direction you can point me to as well.   

With pleasure, David.

For a high-level contemporary treatment by a distinguished philosopher of religion, I recommend Richard Swinburne, Are We Bodies or Souls? Oxford UP, 2019.  The Soul Hypothesis, eds. Baker and Goetz, Continuum 2011, is a collection of essays by analytic philosophers. For a hard-core old-time  Thomist treatment, one that is probably not quite in line with your current interests as a medical doctor, but still highly relevant given your Catholic upbringing, take a gander at  Reginald Garrigou-Lagrange, Life Everlasting and the Immensity of the Soul (no bibliographical details in my copy!).  More relevant to your biomedical interests is Norman M. Ford, When Did I Begin? Cambridge UP, 1988. 

Directly relevant to your concerns is  the mercifully short Were You a Zygote? by G. E. M. Anscombe. Also of interest is Erich Klawonn, Mind and Death: A Metaphysical Investigation, University Press of Southern Denmark, 2009.

I'll add further titles if they occur to me. Comments are enabled  if anyone wants to make suggestions.

Finally, here is a review by Thomas Nagel, no slouch of a philosopher, of the Swinburne volume mentioned supra.
