This is an interesting problem, I’ll try my hand at it, here we go:
A. If wholes exist, then either wholes are identical with their parts or distinct from them.
This premise seems straight forward enough, no further comment.
B. Wholes and their parts have incompatible properties.
I am not sure about the usage of the term “incompatible” here, one could easily venture to say that the whole has properties that the part doesn’t have, but to assert incompatibility is a strong assertion. Either clarification regarding the usage is required or evidence for the claim or both.
C. Two entities cannot be identical if they have incompatible properties.
See the comment in (B). Though this seems to be an accurate statement, even if we understand “incompatible” in the sense of “different”.
D. So, wholes are not identical with their parts (B, C).
This follows, no further comments on this premise.
E. The properties of wholes can be entirely explained in terms of facts about their constituent parts.
This is a contentious claim, and hinges on what one would count as a valid explanation. Often times a “third” property (so to speak) arises out of the interaction or congealment of multiple parts, a simple example would be H2O. Hydrogen by itself has specific qualities, and oxygen by itself has specific qualities, though when combined they produce water, a compound with its own unique properties. Can these unique properties be explained? Perhaps. Can they be explained by the totality of facts regarding the interactions between the parts along with the general properties of each individual part? If the answer to the previous question is yes, so then is the answer to this.
(Note: I am not arguing against the premise here, just pointing out that it is contentious along with the highlighting of what I think to be a pertinent fact)
F. Entities whose properties can be entirely explained in terms of facts about their constituent parts are not distinct from their parts.
This is a problematic assertion, if we are to assert that entities with distinct properties are not identical, then that means they are distinct. If that is the case, what constitutes distinction is not how the entity is explained, but rather the perceived properties of the entity.
Either these properties that are explained by the interaction of the individual parts are assigned to the individual parts or they are assigned to some other entity, in the premise (B), it seems as if these properties are not assigned to the individual parts, so it is assigned to some other entity, the entity that owns that property, generally what we refer to as the whole.
Furthermore, why should it be the case that if something can be explained in terms of something, that it is identical to that thing? Just some food for thought.
G. So, wholes are not distinct from their parts (E, F).
No comment here.
H. Therefore, wholes don’t exist (A, D, G)
I see how this is derived from assuming the previous premises, but this causes an interesting question to arise from the assertion of premise (B). It was mentioned that wholes and parts have “incompatible” properties, but now we have concluded that wholes do not exist, a question regarding the properties you alluded to earlier is now lingering, that being, what happened to these properties? If we conclude that wholes do not in fact exist, then these properties that were mentioned should belong to the parts, but it was mentioned earlier that these parts are “incompatible” with such properties, a seeming dilemma in the position (unless you toss out the properties with the whole, but that really wouldn’t explain where the properties came from or provide any justification as to why you would discard them).
That’s my two cents, feel free to comment.
Addendum:
After getting some sleep, it has dawned on me that the argument makes an interesting claim, (C) states that “Two entities cannot be identical if they have incompatible properties” and (F) states that “Entities whose properties can be entirely explained in terms of facts about their constituent parts are not distinct from their parts”. These two premises for the criteria for “valid” distinction in the argument and can be formalized as follows:
IP - “Incompatible properties” (for practical purposes I will be understanding this as unique properties, see the comments above on B)
D - “Distinct”
EP - “Explained by parts”
- A: IP -> D (Premise C)
- B: EP -> ~D (Premise F)
The first premise reads “If the entity has unique properties (properties the parts do not have), then it is distinct (from its parts).
The second premise reads “If the entity is explained by its parts, then it is distinct (from its parts)”.
Given these two, further statements can be derived:
- C: D -> ~EP (Contrapositive of 2B)
- D: IP -> D -> ~EP (1A & 1C)
- E: IP -> ~EP (2D & Transitivity)
Assuming I didn’t err in my logic, it can be said that the premises you have presented, specifically (C) and (F), state, albeit implicitly, that if an entity has incompatible properties with its parts, then its parts do not fully explain it. From this, one of three things must be the case if we wish to preserve the statement: Either premise (B) is false, that being wholes do not have unique or “incompatible” properties from their parts, or premise (E) if false, or one (or both) of the two premises (C and F) is false.
Now if the assertion is that “if wholes exists, then wholes have distinct or ‘incompatible’ properties from their parts and they are explained by their parts”, then it follows that wholes do not exist (assuming the contested premises and their derived statements are sound), but if this is the case, the issue regarding these unique properties (see the comments on conclusion H) still stands, resulting in premise (B) being very problematic if assumed to be true.
