Hi Mr. Bunbury,
Thank you for the response. Some thoughts:
I do not disagree with the above, my point was from the aspect of reality as it exists in God. “I think therefore I am”? is more like “God thinks therefore I am”.
You’ve hit on a important point here.

All being apart from God’s being is sustained in existence by God. Technically when we give the definition of “substance” as that which exists in itself and does not inhere in another, what remains unsaid is how that existence comes about and how it is preserved. In both cases, it is from God and preserved in being by God.
Nevertheless, we are speaking of the accidents of some thing. Both the substance AND the accidents are real, have being, and exist apart from the mind of the observer. The difference is that where a substance exists in itself, accidents (normally) exist or inhere in an underlying substance. It seems to me that whatever mechanism we wish to develop about the way we perceive the reality of substance or accidents is a bit of a different consideration.
Earnest Bunbury:
The philosophical question of how we know is based, for me as proposed by philosophers (. . .) on phantasm, the mental recreation of an object in the mind that is not reality but only a phantasm of what is “real”.
This is true in Aquinas’ system, but the phantasm is generated by the senses based upon the extra-mental reality that exists outside of the senses. You are right that the phantasm isn’t reality, but there still is an extra-mental reality upon which it is based.
I mentioned above that accidents (which really exist) normally exist in another being. This isn’t the case with the Eucharist – here the accidents (although they still really exist apart from our minds*)* inhere in no underlying being. God keeps the accidents directly in being (the same way God keeps substances directly in being).
It’s a fine point, but in my view a corollary to the Church’s teaching on the Real Presence and the eucharistic change.
For reference here is a passage from Fr. Ott’s *Fundamentals of Catholicism:
The Sacramental Accidents retain their physical reality after the change of the substance. (*Sent. certa.)
*Many Cartesian Theologians of the 17th and 18th centuries (. . .) denied the physical reality of the accidents, by applying to the doctrine of the Eucharist, the teaching of Descartes, that there are not absolute accidents, that is, really distinct and separable from the substance, but only modal accidents, that is not really distinct from the substance and therefore also not separable from it. They declared the sacramental appearances to be subjective impressions of the senses effected in a miraculous manner by the omnipotence of God.
This opinion is incompatible: a) With the teaching of the Council of Trent, which says that all appearances “remain,” that is, stay behind after the transformation of the terminus totalis a quo. b) With the whole teaching of Tradition, which has not the slightest doubt that an objective reality corresponds to the impressions of our senses (. . .) c) With the concept of Sacrament, which demands an objective sign, if the Sacrament is not to become a merely apparent Sacrament.
If the accidents which remain in the Eucharist are subjective and not objective then God would be creating
the illusion of reality in regard to them, which seems somewhat unbecoming. Especially since, as is mentioned by Ott, sacraments are
sensible signs. . . real stuff we touch.
What do you think Mr. Bunbury? I think, now, that I see how you are approaching it. You *aren’t *saying that the appearances only exist in the mind, are you? Maybe what you are saying is that the appearances (which really exist outside of the mind!) don’t
correspond to any underlying substance. That is certainly true!
Thank you very much for the discussion! :tiphat:
