I know that accidents are real in that they get their being from the substance in which they inhere. So " red " is real in the substance of the Rose or in any other substance in which it inheres. Of course science would say that a lot more is going on here and with sound, etc.
Science, in my opinion, tells us the mechanism by which the redness inheres, but it does not disprove that the redness is inherent. (I am not saying that you say that, but this was a common error among philosophers of the Modern period, such as Descartes and Kant: they thought they could reduce qualities to quantity.)
I just think that certain kinds of accidents ( pushing, walking, twirling, etc ) are not beings even in an extended sense. They are the actions ( acts ) of a being. Now I am not a teacher, writer or commentator or anything.
I mostly agree. Aquinas calls those kinds of accidents
operari (action), which corresponds to Aristotle’s categories of
to poiein and
to pathein (action and passion).
Operari is certainly a notch below the accidents that are closest to substance, such as quality and quantity. However, see below.
So when I talk of being I mean a substantial being, the kind of being of which Aristotle says we we are first aware. And when I talk about accidents, even quantity, I always say these are simply accidents of a being/substance/nature. But now I see that I shall have to say " accidents of being per se

.
Technically, for Aristotle
per se and
per accidens being refer to the manner of attributing, not the intrinsic ontological structure of a substance. “Being” (as a linguistic or logical term) is
per se if you are trying to say that the predicate is associated with the subject necessarily (or at least mostly necessarily), and
per accidens if you are saying that it is simply circumstantial. I probably could have explained that better in my previous post. You seldom have to add the words
per se in a sentence; we understand it from the context.
You have to admit that it would be very awkward if I said that " walking " was a being of a being or that it was the being of a substance. Such contortions would make conversation unbelievably complicated, if not impossible. So the normal expressions used would be something like, “…red is an accident inhering in a substance, " or " … in a real being…,” or " …in a being per se ( and even this is awkward ), " or perhaps, " …in a substantial being ( perhaps this would be the best expression ). "
I understand what you and Richa are saying, I just think that Aristotle misses the mark here that’s all. I don’t think I am the only one who has had a problem with his Categories. This is no slight to either Aristotle or Thomas, both were great men. But both were subject to error like all men. And even Thomas disagreed with Aristotle from time to time.
It is obviously OK to disagree with either Aristotle or Aquinas, although (in tongue and cheek) you might want to choose better company than Descartes, Kant, Hegel, and Heidegger

.
However, I still find it difficult to maintain that actions (
operari) don’t participate in any way whatsoever in being: either you “are” walking, or you “aren’t;” the action either takes place, or it does not.
I don’t think we need to make any linguistic contortions to see that. We just say, “the rose ‘is’ red,” and understand that “to be” means “to inhere as a quality;” or “the rose ‘is’ growing,” and understand that " ‘to be’ growing" here indicates an action on the part of the rose. One of the great contributions of Aristotle (in my opinion) is to realize that “to be” is not a “univocal” term: its meaning changes according to the context; nevertheless, it is never completely ambiguous, since it always makes a reference to substance.
One of the common misreadings of Aristotle and Aquinas (in my opinion) is to look at substance and accident as if they were bricks making up a building: the substance would be the slab of concrete making up the foundation, and accidents would be the bricks added on top, as if each accident were a little mini-substance.
In reality, the better image would be that of a spring or water fountain: the accidents (and ultimately even the actions, or
operari), flow forth from the substance, as the water from the spring.
So, neither Aquinas nor Aristotle would have considered accidents as “beings of a being,” but as emanations of a being (i.e., of a substance).
