McDonough Reply (Part 2)

At the end of her last post, Armstrong raised the question of why we should be tempted to follow Leibniz’s way out of Della Rocca’s Dilemma if we reject key aspects of Leibniz’s way into the problem. The short answer, I think, is that the aspects of Leibniz’s way into the problem that are most problematic are not essential to his way out of Della Rocca’s Dilemma. Leibniz’s suspect commitment to relations being at least partially ontologically grounded in the divine intellect makes Della Rocca’s Dilemma more challenging, not less. Watching Leibniz juggle five balls makes it easier to see how we can juggle three.

 

I introduced the distinction between ontological and semantic grounding largely to explain the sense in which relations are and are not ideal for Leibniz. If we turn specifically to Della Rocca’s argument against the possibility of relata jointly grounding relations I don’t think that distinction is particularly important. What is important is the thought that at least some relational facts might be wholly grounded in their relata, that, for example, the fact that a and b co-exist might be wholly grounded in the existence of a and the existence of b. Borrowing notation that I learned from my colleague Selim Berker, we might express (what I’ll call) Leibniz’s Key Thought by saying that [p • q] <- [p], [q] where “[p]” is shorthand for “the fact that p,” and “[p] <- [q]” is shorthand for “[p] is fully grounded in [q].”

 

Although I think most contemporary philosophers accept Leibniz’s Key Thought, Della Rocca and Bradley would, I believe, demur. They think that [p], [q] cannot fully ground [p • q] on their own. Something more, in their view, is needed, namely, [p] and [q]’s standing in a certain relation, call it “R.” So, to fully ground [p • q], we’d need at least [p], [q] and R. But wait, they’ll say, [p], [q] and R also can’t fully ground [p • q] on their own. For the same reason as before, something more is needed, namely, their standing in some relation, call it “R’”. And so on. If one allows the first regress, obviously we’ll be off to the races. Either we will be committed to doubling back at some point, falling into a vicious circle, or we’ll be launched on an infinite regress. I think contemporary rationalists should follow Leibniz’s lead and nip the regress in the bud by accepting his Key Thought.

 

If I’ve understood her correctly, Armstrong sees Della Rocca’s argument against the possibility of relata jointly grounding relations slightly differently. Her suggestion is that, according to Della Rocca, “the coexistence of a and b requires the relation of partial grounding, which is itself grounded in the coexistence of a and b.” This suggestion, she thinks, generates an “additional fact in need of explanation … namely, why does the fact that a’s existence partially grounds a and b’s coexistence require appeal to both a and b?” But, as I think Armstrong would agree, if there is such a fact as a’s existence partially grounds a and b’s coexistence, it looks like it too can be grounded in a’s existence and b’s existence. Using Berker’s shorthand, and letting “[p] <- – – [q]” stand for “[p] is partially grounded in [q],” we can say [[p • q] <- – -[p]] <- [p], [q]. If Leibniz’s Key Thought is accepted, it will take care not only of Della Rocca’s Dilemma as I’ve interpreted it, but also as Armstrong has interpreted it. Either way, contemporary rationalists could do a whole lot worse than to follow Leibniz’s way out of Della Rocca’s Dilemma.

 

Thanks again to Armstrong for her careful reading and thoughtful comments. And thanks to Stewart Duncan for setting up our exchange.

A Leibnizian Way Out of the Rationalist’s Dilemma (Part 2)

In Part 1, I raised some questions about how to understand semantic grounding as a response to the Rationalist’s Dilemma within Leibniz’s system. In this post, I will explore the notion of semantic grounding as a response to the dilemma as it arises for adherents to the PSR more generally.

 

According to McDonough’s solution, relations are semantically grounded in their relata jointly and still satisfy the PSR. In particular, McDonough thinks that the relation of coexistence is unproblematically grounded in the existence of its relata:

 

If one has an explanation for the fact that my dog exists, and one has an explanation for the fact that my cat exists, then ipsis factis one has an explanation for the fact that both my dog and cat exist…what is harder to imagine is [Leibniz] agreeing with the intuition that, say, having explained the fact that one substance exists and the fact that another substance exists, there should remain an additional fact still standing in need of explanation, namely, the fact that both substances exist (McDonough 379).

 

However, Della Rocca offers an argument against the possibility of relata jointly grounding relations. This argument is part of what makes Della Rocca’s dilemma worrisome for those that accept the PSR but reject Leibniz’s views on the ideality of relations (or substance-accident ontology for that matter). Della Rocca argues that the coexistence of objects cannot be grounded in the existence of those objects as follows:

 

…in order for a relation between a and b to hold, the relation must be partially grounded in a (and also partially grounded in b). Call this relation of partial grounding (between a and R) R’. So R holds in part because R’ holds. Why does R’, the relation of partial grounding between a and R, hold? There’s a relation, R’, of partial grounding between a and R only because a coexists with b. Call the relation of coexistence R”…Now in virtue of what do a and b co-exist, i.e. in virtue of what does the relation, R”, of coexistence hold? Just as R’ obtains in part because a and b coexist, so too R” obtains because a and b coexist…so R” holds in part because R” holds…And here we reach a circular explanation of a relation (Della Rocca 149).

 

The key move in the above argument is that grounding the coexistence of a and b requires the relation of partial grounding, which is itself grounded in the coexistence of a and b. McDonough, as we saw above, thinks that coexistence can be semantically grounded in existence, because it’s unlikely that “there should remain an additional fact still standing in need of explanation, namely, the fact that both substances exist.” It is, however, worth revisiting this issue precisely because Della Rocca does not think that coexistence directly appeals to the coexistence of both a and b. Instead, the relation of partial grounding generates appeals to the coexistence of a and b. My point is that the additional fact in need of explanation is a fact about grounding—namely, why does the fact that a’s existence partially grounds a and b’s coexistence require appeal to both a and b?

 

Perhaps Della Rocca is emphasizing the partial aspect of this relation. In order for it to be true that a partially grounds the coexistence of a and b, b must also partially ground coexistence. So the conditions under which a partially grounds a and b’s coexistence depends upon both a and b existing, or their coexistence.

 

On the one hand, I’m not sure I’m doing Della Rocca’s objection justice for, when reframed this way, it is still difficult to see why the partial grounding relation requires appeal to coexistence. The partial grounding relation itself is not so specific as to involve the other objects involved in partial grounding. Thus, to my mind, a’s existing partially grounds the coexistence of a and b in the same way that a’s existing partially grounds the coexistence of a and c, in the same way it would partially ground the coexistence of a, b, and c.

 

On the other hand, it is also true that a’s existence does not partially ground a and b’s coexistence without b’s existence. This, at least for me, gives Della Rocca’s worry some bite. But what this suggests is that a’s partial grounding depends on b’s existence, and thus only derivatively on the coexistence of a and b. So we have reason to think that a’s partial grounding relation too depends on a’s existence and b’s existence. This is consistent with what McDonough says about semantic grounding: not only is coexistence grounded in existence, but also the partial grounding of coexistence is grounded in existence. What is surprising, perhaps, is that a’s partial grounding depends upon b’s existence, but as long as it does not depend on their coexistence it is not circular.

 

Della Rocca’s argument above focuses on circularity, but he also raises an infinite regress worry—a Bradley-style regress—whereby the relation between x and y is grounded in a further relation which is grounded in other relations which are themselves grounded in other relations and so on (151). The relation of partial grounding is itself partially grounded thus there is the possibility for an infinite regress of grounding relations. While Leibniz seems opposed to an ontological regress of relations (see Mugnai 2010) it is less clear whether he would object to a semantic regress. Because the issue here is rooted in the ontological aspect of relations I have focused more on the circularity worry. However, if partial grounding can be grounded in existence, then even if there are an infinite number of semantic grounding relations as long as the ground for each is not itself a relation there is not a vicious semantic regress.

 

I’ll leave it to the reader to determine the gravity of Della Rocca’s objection, and the viability of my recommendations using McDonough’s resources. But, as I’ve rendered it, I think that Della Rocca’s objections raise the following important questions for developing a notion of semantic grounding:

 

1. Do semantically grounded relations generate further truths about grounding?
2. If grounding is a relation, are its instances semantically grounded?
3. Is coexistence the (partial?) ground of the grounding relation for coexistence?

A Leibnizian Way Out of the Rationalist’s Dilemma: McDonough Reply (Part 1)

I want to start off by thanking Chloe Armstrong for carefully reading and presenting my paper. She does a great job of summarizing my overall view in the beginning of her post. After that she proposes to reexamine the notion of semantic grounding first with respect to Leibniz’s own system and then with respect to Michael Della Rocca’s more general Rationalist Dilemma.

 

In my paper, in a footnote, I note that “Leibniz’s full semantics is, of course, further complicated by … his esoteric view of truth.” Armstrong presses this point, wondering how we might reconcile my “account of semantic grounding with Leibniz’s conceptual containment theory of truth.” The answer she offers seems to me essentially right. Given Leibniz’s conceptual containment theory of truth, at the end of the day, he’ll have to say that the truth of relational statements is at least partially dependent upon concepts in the divine intellect. The response I offer on Leibniz’s behalf to Della Rocca’s challenge, however, should remain effective as long as he allows – as I think he does, and as Armstrong suggests – that the truth of relational statements concerning co-existence are either partially or immediately grounded in features of the actual world.

 

Della Rocca’s Rationalist Dilemma is a challenge not just for Leibniz but for all would-be rationalists. In my paper, I suggest that at least some contemporary rationalists might want to follow Leibniz’s way out of Della Rocca’s Dilemma. Some of Leibniz’s background commitments are, however, highly contentious. Armstrong thus wonders, quite fairly, “Why, then, should we take Leibniz’s way out if we reject key aspects of Leibniz’s way into the problem?” Why indeed? I’ll take up this question in my reply to Armstrong’s second post.

A Leibnizian Way Out of the Rationalist’s Dilemma (Part 1)

[Comments on Jeffrey McDonough’s “Leibniz, Spinoza and an Alleged Dilemma for Rationalists” (Ergo 2015), by Chloe Armstrong]

 

Consider the following argument that starts with a Leibnizian view about relations:¹

1. Relations are ideal; they are not accidents that inhere jointly in their relata but exist insofar as they are apprehended or cognized by a mind comparing the relata.²
2. Coexistence is a relation.
3. Thus, the coexistence between distinct objects is ideal.
4. If coexistence between distinct objects is ideal, then no numerically distinct objects can coexist.
5. Therefore, no numerically distinct objects can coexist.

The conclusion of the argument endorses radical monism—the   denial that there exists a plurality of objects (including substances, attributes, and modes). This conclusion is unacceptable for Leibniz who maintains that there is a plurality of substances each with a multiplicity of states. (See, e.g., Monadology §§1-8.) Leibniz is in trouble if his analysis of relations undermines the existence of distinct objects. However, the problem runs deeper because Leibniz’s views about relations results from his commitment to the Principle of Sufficient Reason (PSR):

 

If an object x is in a certain state (or has a certain property or whatever), then there must be some thing or things in which the state is grounded, some thing or things in virtue of which the thing is in that state (McDonough 368).

The PSR, so formulated, requires that all states—including relations—be grounded. If the only way to ground relations is to affirm their ideality, then Leibniz’s commitment to the PSR seemingly entails radical monism. Michael Della Rocca (2012) summarizes: “Leibniz’s dilemma is this: EITHER give up the claim that there is a multiplicity of objects and that there are states of objects OR give up the claim that relations are grounded” (157).

 

Leibniz’s Way Out:

Jeffrey McDonough argues that Leibniz has a way out of this dilemma: the fact that coexistence is an ideal entity does not rule out the possibility of coexisting objects. The key is to distinguish two types grounding relations: ontological grounding and semantic or truth-making grounding. The ontological ground of a relation is that in virtue of which the relation exists (373). For example, the ontological ground of the relation of coexistence is an idea in God’s mind. Semantic or truth-making grounding explains why a statement or proposition is true, and, in the case of relations, it specifies the conditions under which a relational predicate holds (375). McDonough observes that the fact that the ontological ground of relations is ideal and mind-dependent does not thereby render the semantic ground of relations mind-dependent. Instead, the truth of relational predication might well be grounded in non-relational properties of each of the relata. In the case of coexistence, McDonough claims that the semantic ground of the relation is the existence of each of the relata. Put differently: coexistence is semantically grounded in existence. Thus, premise (4) of the above argument is false because coexistence is ontologically ideal but semantically real. If coexistence is a two-place relational predicate, Rxy, the fact that R picks out an ideal entity does not prevent Rab from being true as long as a and b each exist.

 

Semantic Grounding in Leibniz’s System:

I want to consider semantic grounding first with respect to Leibniz’s own system, and then with respect to Della Rocca’s more general way into the Rationalist’s Dilemma (which does not depend on uniquely Leibnizian views about the ideality of relations).

 

I’m particularly interested in the first issue, since it is not clear that we can successfully account for semantic grounding of coexistence in the Leibnizian system. This is because there are texts in which Leibniz not only identifies relations as dependent on God’s mind, but also seems to affirm that truth is similarly dependent:

 

The reality of relations is dependent on mind, as is that of truths; but they do not depend on the human mind, as there is a supreme intelligence which determines all of them from all time (New Essays 265).

God not only sees individual monads and the modifications of every monad whatsoever, but he also sees their relations, and in this consists the reality of relations and of truth (Notes for Leibniz to Des Bosses, 5 February 1712).

The above passages seem to assimilate the ideality of relations and the ideality of truth(s). If both the ontological and semantic grounds of coexistence are ideal, McDonough’s distinction between ontological and semantic grounds might not be viable for Leibniz.

 

This issue is also tied to the question of how to reconcile McDonough’s account of semantic grounding with Leibniz’s conceptual containment theory of truth. While it is very natural to ground the truth of coexistence of a and b in the existence of a and the existence of b, Leibniz famously maintains that truth is a matter of conceptual containment. Whether existence is contained in the complete concepts of substances is a controversial interpretive matter, but Leibniz does make it clear that the truth of other relations, such as Caesar having crossed the Rubicon, is true because the concept of having crossing the Rubicon is contained in Caesar’s concept. This suggests that—contra McDonough’s suggestion—the semantic ground for relations rests not in features of the relata themselves, but their concepts or notions.

 

I think, however, that reconciling the conceptual containment theory of truth with McDonough’s account will help explain how relational truths are semantically dependent on God’s mind, but not ideal in the same way as the ontological ground of relations. Perhaps relations are semantically grounded in both the existence of the relata and the concepts of the relata. For example, if God creates substances according to their complete concepts, then complete concepts semantically ground relations by (at least partially) grounding the relevant features of the substance that in turn ground the relation. In this sense truth is mind-dependent, but not ideal, because there is no individual entity corresponding to God’s idea of a relation in the world, but there are entities corresponding to complete concepts and those entities are the immediate ground of relational truths.

 

Both Della Rocca and McDonough stress that Della Rocca’s dilemma is not unique to Leibniz’s system, but confronts anyone committed to the PSR. That said, the above formulation of the problem depends on distinctive Leibnizian commitments including the ideality of relations. Why, then, should we take Leibniz’s way out if we reject key aspects of Leibniz’s way into the problem? I’ll take this question up in Part 2.

 

[Thanks to Stewart Duncan for inviting this post, and thanks to Jeff McDonough in advance for taking the time to respond.  In “Leibniz, Spinoza and an Alleged Dilemma for Rationalists” McDonough not only steers us through some of the most challenging aspects of Leibniz’s system, but also–amidst these opaque topics–develops the resources to engage the Rationalist’s Dilemma.   My comments reflect only a portion of McDonough’s enlightening and subtle discussion.]

Notes:

1. This is drawn from Jeffrey McDonough’s argument in “Leibniz, Spinoza and an Alleged Dilemma for Rationalists” (Ergo 2015). McDonough’s version is based on Michael Della Rocca’s discussion in “Violations of the Principle of Sufficient Reason (in Leibniz and Spinoza),” in Metaphysical Grounding: Understanding the Structure of Reality (Eds. Fabrice Correia and Benjamin Schnieder), Cambridge University Press: 2012, 139-164.

2. The sense in which relations are mind-dependent does not follow directly from Leibniz’s immaterialism. The distinction between ideal and real is one that Leibniz draws within his system. Relations are ideal in the sense that they are not states of the substances that they relate, but instead states that depend on a mind that understands the relevant features of the substances and compares them.

Experimental Philosophy Through History conference (NYU, Feb 20)

 

The division between authors into rationalist and empiricist is often deemed artificial. A frame imposed on early modern philosophers, not of their own making. That between speculative and experimental philosophy, by contrast, is one that also authors in the seventeenth century would have been able to identify with.

Such resonance makes it extra exciting that NYU is holding a conference on experimental philosophy with a historical bend, Experimental Philosophy Through History, on February 20th. Areas discussed range from intuition in Confucian ethics to neo-Kantian anti-empiricism, via Hume, Locke, and decapitation.

Here is the program:
