May I recommend the philosophy of Herman Dooyeweerd. For the best basic introduction to his philosophy (in English), may I recommend ch 11 (Theory of Reality), ch 12 (Theory of Society), and ch 13 (Theory of “The State”) in “The Myth of Religious Neutrality” by Roy A Clouser (will need to read chs. 1-10 for chs 11-13 to make sense) 😊

I see the "breath" is like the code behind matter – what defines the -ness of something (to a degree. That code is expandable). For matter to arrange into "thing" – breath defines the structure upon which order is built.
I feel like entropy is evidence of that quality of breath/code – it flows, never static, and so matter is never statics in itself.

It is as if they are trying to explain stoicism in the same way as a person that has glimpsed a breast out of the corner of their eye, but never actually seen one naked in its full glory. All is enigmatic cleavage.

Regarding preference and good.
Maybe the way to think about it is that some things are morally good and some things are useful. Drinking water is morally neutral, but it is useful so you should still do it.

I try to live in a stoic point of view in that I hold no attachments for anything or anyone. A lot of it is automatic due to a lifetime of losing everything I have and having to start over a few times and from losing so-called friends. I try not to stress about anything I have no control over and cannot change. I find this refreshing, more free, like I don't have to carry around unnecessary attachments or stress. That's just my experience. I think a lot of people with depression and anxieties could benefit from learning to detach.

Hi Alex,
I’m writing because something has been weighing on me ever since you announced you were no longer vegan, and I’ve struggled to articulate it until now.
When you stepped back from veganism, you mentioned you would still publicly advocate for reducing animal suffering and continue engaging with the ethical arguments. But from the outside, it appears that this advocacy has almost entirely stopped. What confuses me most is how someone who once argued so powerfully that killing sentient animals for trivial reasons is morally indefensible could now see that practice as acceptable, or at least no longer feel compelled to speak against it. I’m trying to understand how such a deep moral conviction could reverse in this way.
This question matters to me personally because your work was a major part of what led me to go vegan. Before encountering your arguments, I resisted the idea completely. But one by one, the justifications I relied on—cultural, practical, psychological—dissolved under the weight of the reasoning you presented. I reached a point where continuing to eat animals felt impossible. It was one of the most ethically transformative experiences I’ve had, and it was largely because of you.
So I hope you can understand why your change in stance feels unsettling, even disorienting. I’m not trying to corner you or demand an explanation—I’m genuinely trying to make sense of how someone who articulated the moral necessity of veganism so clearly could come to see things differently. What changed, internally or philosophically, that made the killing of sentient beings for comparatively trivial preferences seem permissible again?
If you’re open to sharing your thinking, I’d really appreciate it.
Thanks for taking the time,
Xav

36:38 Pneuma or breath seems to be very similar to the modern physics concept of energy.
Everything is made of matter and energy where matter is the passive physical stuff and energy is the active physical element.

Even though a bit more academic, the first part was well explained, easy to follow, and I feel like it helped me to understand more about where the Stoics' ethics and moral come from. I rarely comment on YT but it was a pleasant and enriching conversation to follow. Sellar great discovery. I will follow up on his books and on Musonius Rufus as well 🙂

I find the parallel between the stoic concept of nature “ending” and the bing bang to be quite interesting. Even down to a more recent theory that the universe is currently shrinking and will result in another big bang, echoing the concept of nature repeating itself.
Obviously it’s just a surface deep connection I’m pointing out right after hearing it and haven’t thought on it too deeply.
@oskyys6853

I find that stoicism is often misinterpreted by the internet
Everyone just assumes stoicism is being “tough” not getting emotional over small grievances and completely ignore the virtuous aspect

I would like to know how the Stoics identify selfhood as compared to Buddhism. Can it be independent or is it part of the larger process of Logos?

Stoicism is not an athiest philosoophy. It is a pagan outlook rooted in surviving wars and bloodshed. Marcus Aurelius was a pagan Roman Emperor. All of the stoic philosophers were pagans.

I still think stoicism can be a cop-out, but with some useful points.
Everyone can take something from it that is helpful and discard the rest.
A really interesting talk. I loved it. Thanks.

Stoicism can make you a better and resilient person, but it does not necessarily destroy the human identity—which is what most founders of most religions believe is necessary for true salvation.
In essence, stoicism is a wonderful tool to live rationally within the world—but it is not the same as the profound liberation that comes from completely letting go of the human perspective in favor of a "divine," forgiving and unified consciousness.

Hey Alex, 👋 this is Jackson from the Truth & Tradition Podcast. I am on a mission to watch every one of your videos and leave a comment on each of them.
Super cool to hear more about Stoicism. All I normally hear about it is tid bits from Marcus Arillius. The idea that we should be stoic though because ontologically that is how we preserve ourselves is super cool! I didn't know that about Stoicism. Thanks for sharing! 🙏

Just realized that John Sellars was also the expert on Stoicism Peter Adamson talked to in the "History of Philosophy without any gaps". I guess King's College is the "hidden variable" here. 🙂 Good stuff. He was impressive there and he is impressive here.
