I answer that, True and false are opposed as contraries, and not, as some have said, as affirmation and negation. In proof of which it must be considered that negation neither asserts anything nor determines any subject, and can therefore be said of being as of not-being, for instance not-seeing or not-sitting. But privation asserts nothing, whereas it determines its subject, for it is "negation in a subject," as stated in Metaph. iv, 4: v. 27; for blindness is not said except of one whose nature it is to see. Contraries, however, both assert something and determine the subject, for blackness is a species of color. Falsity asserts something, for a thing is false, as the Philosopher says (Metaph. iv, 27), inasmuch as something is said or seems to be something that it is not, or not to be what it really is. For as truth implies an adequate apprehension of a thing, so falsity implies the contrary.

Seconds, for the term "true" to have any content, it must not to apply equally to all things; falsity must be at least a possibility. For my part, it's unclear to me how we can have falseness without an intellect. For instance, stars, rocks, numbers, and trees are not true or false, but rather beliefs and statements about them are. Nor will it do to have truth and falsity be properties of "language," as isolated from any consideration of language users. Rocks do not come to know things by having truths carved into them, and in a lifeless universe of random shifting sands, a proposition that happens to be spelled out in English by pure chance means nothing to anyone. — Count Timothy von Icarus
the idea that all knowledge and belief is reducible to atomic propositions, that knowledge is the type of thing that can be atomized or is a whole that is merely the sum of its parts. — Count Timothy von Icarus
At the end of the day it is not merely sentential. Knowledge/truth is more than a set of sentences. — Leontiskos
St. Thomas makes the case for this — Count Timothy von Icarus
“opposite assertions cannot be true at the same time” (Metaph IV 6 1011b13–20) — SEP on Aristotle and Non-Contradiction
But I don't see Thomas saying that the true and the false are not contradictories, nor do I see Aristotle saying that. Classically, true/false are contradictories:
I answer that, True and false are opposed as contraries, and not, as some have said, as affirmation and negation [i.e. contradictory]. In proof of which it must be considered that negation neither asserts anything nor determines any subject, and can therefore be said of being as of not-being, for instance not-seeing or not-sitting. But privation asserts nothing, whereas it determines its subject, for it is "negation in a subject," as stated in Metaph. iv, 4: v. 27; for blindness is not said except of one whose nature it is to see.

Perhaps you need to define what you mean by "contrary."
A major difficulty for modern thought has been the move to turn truth and falsity into contradictory opposites, as opposed to contrary opposites (i.e. making truth akin to affirmation and negation). — Count Timothy von Icarus
I answer that, True and false are opposed as contraries, and not, as some have said, as affirmation and negation. (Aquinas)
A capacity meta logou is categorematic: it is specified by a verb -- say, to heal -- and its positive and negative acts are contraries. A logical capacity is syncategorematic: it is specified by a proposition, and its positive and negative acts are contradictories. — Thinking and Being, 61
Capacities meta logou are two-way capacities because they involve logical capacities. It is because doctors must judge how best to heal their patients that they can also judge how best to poison them. — Thinking and Being, 61
So, without having to make any commitments to any specific sort of correspondence or identity relationship between thought and being, we can simply leave it as "truth is the conformity or adequacy of thought to being." — Count Timothy von Icarus
Reducing truth to a binary seems to edge us towards primarily defining truth in terms of "propositions/sentences" and, eventually, formalism alone, and so deflation. This is as opposed to primarily defining truth in terms of knowledge/belief and speech/writing.
The key difference is that, in the latter, there is a knower, a believer, a speaker, or a writer, whereas propositions generally get transformed into isolated "abstract objects" (presumed to be "real" or not), that exist unconnected to any intellect. Such propositions are true or false (there is no gradation) simpliciter. Such a view seems to require some dubious assumptions. — Count Timothy von Icarus
The essential unity of the thinker with the thought, the knower with the world, can only be shown by rejecting, as Kimhi does, the idea that a proposition can be true or false in the absence of some context of assertion. — J
Sebastian Rödl — J
So yes, the distinction you're making between contraries and contradictories is extremely important. The essential unity of the thinker with the thought, the knower with the world, can only be shown by rejecting, as Kimhi does, the idea that a proposition can be true or false in the absence of some context of assertion.
Are we sure that thought and being exist in the sort of relationship that needs to be "conformed" or "adequated"?
Can we paint a plausible picture that is at bottom monistic?

Agreed, although I don't know if "context of assertion" is the right framing. Beliefs can be true or false without being needing to be "asserted." — Count Timothy von Icarus
Are we sure that thought and being exist in the sort of relationship that needs to be "conformed" or "adequated"?
Well, presumably we need to be able to explain false beliefs and false statements. There is adequacy in the sense of "believing the Sun rotates around the Earth" being, in important ways, inadequate. — Count Timothy von Icarus
Can we paint a plausible picture that is at bottom monistic?
Monistic in what sense? — Count Timothy von Icarus
"Thinking cannot be dependent for its success on anything that is external to it." — Kimhi, 23
What about the quote from the OP? — Count Timothy von Icarus
Yes, something cannot be black and not-black — Count Timothy von Icarus
Edit: For Aristotle contraries allow for an unexcluded middle, but true/false do not, therefore true/false are not contraries. Cf. Metaphysics IV.7 - 1011b23. — Leontiskos
Truth and falsity are mutually exclusive in cases where... — Count Timothy von Icarus
I always assumed Thomas's point here was pointing back to Avicenna and ontological truth. — Count Timothy von Icarus
Such propositions are true or false (there is no gradation) simpliciter. Such a view seems to require some dubious assumptions... — Count Timothy von Icarus
Truth represents a perfect adequacy between the intellect and being. Falsity is the absence of this adequacy. If any inadequacy makes a belief or statement false, that seems to be quite problematic. For one, it would mean that all or almost all of the "laws" of the natural sciences are false, along with our scientific claims.
A theory or hypothesis might not perfectly conform to reality, but this doesn't make it completely inadequate either. — Count Timothy von Icarus
I know that sounds absurd, but so much depends on how we construe "assertion," and the long thread on Kimhi a few months back revealed a lot of work to be done on this question.
The monist wants to be able to say that there is no disjunction between truth and validity -- that there is something ill-formed or incoherent about "A thinks ~p", as opposed to "A doesn't think p".
In Ad Thalassium 60, St. Maximus the Confessor argues for the superiority of unified and direct experience, as opposed to discursive reasoning/knowing. Similarly, in Philosophiae Consolationis (4.6), Boethius argues that reason is to the intellect as time is to eternity, and what “circle” is to “center.” This is because it is “proper” for reason to be “diffused” (diffundi, i.e., scattered or spread) about many things, and then to gather from them a single cognition (i.e., unifying the “Many” into a “One”). Pseudo-Dionysius makes a similar point, (De Divinis Nominibus, 7.2) claiming that souls have rationality insofar as they “diffusedly encircle” (diffusiue circueunt) the truth of multiple existent things. Conversely, the intellect considers one simple truth and grasps the cognition of a whole multitude in it.
This is the problem from Parmenides that Kimhi begin T&B with, you may recall: How can we think that which is not?
Thinking cannot be dependent for its success on anything that is external to it.
And to say that something is not-black is to say that it is false that it is black. Something cannot be true and false, therefore the true and the false are contradictory:
Okay, that's fair, but ontological truth/falsity as they exist primarily in the intellect. I guess I didn't realize that in the OP you were talking about true/false as states of the intellect. For example, you critique a thesis regarding propositions, and seem to in some way question the LEM:
Surely we agree that "p is false" contradicts "p is true."
What objectionable thesis does your opponent hold? — Leontiskos
The Univocity and Binary Nature of Truth
...
I'm going to make a case against both of these assumptions. — Count Timothy von Icarus
Is the idea here that just thinking something is asserting it? — Count Timothy von Icarus
Philosophers are in the habit of indicating the object of judgment by the letter p. There is an insouciance with respect to this fateful letter. It stands ready quietly, unobtrusively, to assure us that we know what we are talking about. For example, when we do epistemology, we are interested in what it is for someone to know—know what? oh yes: p. If we inquire into rational requirements on action or intention, we ask what it is to be obliged to—what? oh yes: see to it that p, intend that p, if p then q, and so on. However, if we undertake to reflect on thought, on its self-consciousness and its objectivity, then the letter p signifies the deepest question and the deepest comprehension. If only we understood the letter p, the whole would open up to us. — Self-Consciousness & Objectivity
Something cannot be true and false because nothing can both be and not be anything, in the same way, at the same time, without qualification. — Count Timothy von Icarus
When it comes to logic, our predicates should be univocal, and this sort of ambiguity should be ruled out. — Count Timothy von Icarus
But even for propositions like: "you had a good day," the truth of this is not reducible to a binary. Sometimes, if asked if we had a good day, we don't really know. Does this mean that there is no truth as to whether or not anyone ever has a good day? That the sentence is not truth-apt? I don't think so. — Count Timothy von Icarus
Well, the problem that I think is most acute is ascribing truth and falsity primarily to propositions. Actually, it seems that in a lot of philosophy they are the only bearers of truth. That's what leads to, IMO, bad conceptualizations of knowledge. — Count Timothy von Icarus
But I suppose my point is that contradiction in this case is used as the lens through which truth as a whole is analyzed. This leads to concepts like "the one true canonical database of all true propositions" and when concepts like this are shown to be flawed, there is a crash into deflation. Truth ends up being either univocal, and contained in "the one true set of propositions," or else entirely relativized (with some appeals to "pragmatism" as a backstop). — Count Timothy von Icarus
The second, no. — Count Timothy von Icarus
However, we can have propositions that make statements about how true something is to some ideal. "This is a good car." Does this reduce to a binary? I don't think so. Is it simply not truth-apt? I don't think this works either, because a car that won't start is in an important sense not a good car. It isn't true to its purpose. — Count Timothy von Icarus
However, I think that, if we are not careful—and we have not been—this move becomes a major step down the road to deflationism vis-à-vis truth. — Count Timothy von Icarus
"truth is primarily in the intellect and only secondarily (or fundementally) in things." — Count Timothy von Icarus
This is a view that I think is every bit as untenable and radical as either solipsism or epistemological nihilism, its advocates just tend to obscure this fact by ultimately deficient appeals to "pragmatism." — Count Timothy von Icarus
Usually the non-binary response will be an attempt to distinguish different parts of the day instead of collecting it into a single whole.
But is this a matter of the univocity of truth or of the ambiguity of language? And is the LEM being rejected if the truth-value is not binary?
"I took a magnifying glass to every part of your vehicle and found a squeaky axle. Therefore I will not drive or trust it."
Okay, so how would you characterize the view you take exception to?
If I understand what you've written, you and I agree that we don't generally know the world as a bunch of propositions.
This point of view is very congenial to yours, I would think, since Rödl is doubting whether "p" -- a proposition -- could possibly do the things, all by itself, that formalism says it can. A thinker is required.
Not quite. Think of it in terms of Frege's "force" as equivalent to (one sense of) "assertion". The question is then: How does the "content" (of the force/content distinction) make itself known independently? If "p" is different from "I think p", how exactly does p come to be present to us? This quote from Rödl captures the problem:
This works sometimes. I don't think it always does; that is, we cannot reduce thought down to "atomic propositions."
But even if we can, does this mean the higher level statement has no truth value at all? — Count Timothy von Icarus
Both IMO. Language involve analagous predication because being involves analogy. — Count Timothy von Icarus
I don't see how LEM is directly at stake. — Count Timothy von Icarus
A fair characterization. But I think the view of truth as related primarily to isolated (often "atomic") propositions has a wide reach even outside of those who go all the way over into deflation. It affects a lot of analytic thought. — Count Timothy von Icarus
Here is one based on a class I had on the philosophy of AI:
Truth is something that applies to propositions (and only propositions). All propositions are either true or false. If this causes issues (which it seems it will), this is no problem. All propositions are decomposable into atomic propositions, which are true or false. Knowledge is just affirming more true atomic propositions as respects some subject and fewer false ones. Thus, knowledge can accurately be modeled as a "user" database of atomic propositions as compared to the set of all true atomic propositions.
"Artificial" seems to like the key word to apply here.
Alternatively, there are all the deflationary approaches, which often make some of the same assumptions, particularly that truth is primarily about propositions (or more broadly "how a community uses language.") There is the same issue here of missing the "adequacy of thought to being." — Count Timothy von Icarus
When, however, it judges that a thing corresponds to the form which it apprehends about that thing, then first it knows and expresses truth. This it does by composing and dividing: for in every proposition it either applies to, or removes from the thing signified by the subject, some form signified by the predicate... — Aquinas, ST I.16 Article 2. Whether truth resides only in the intellect composing and dividing?
I answer that, In one sense truth, whereby all things are true, is one, and in another sense it is not. In proof of which we must consider that when anything is predicated of many things univocally, it is found in each of them according to its proper nature; as animal is found in each species of animal.
...
If therefore we speak of truth, as it exists in the intellect, according to its proper nature, then are there many truths in many created intellects; and even in one and the same intellect, according to the number of things known. — Aquinas, ST I-16 Article 6. Whether there is only one truth, according to which all things are true?
I think the equivocity attaches to the term 'good' rather than to the truth value, but even an assertion utilizing analogical equivocity must have a determinate and assertable form. If it doesn't then there is not any unitary thing being asserted.
The question for the equivocity of truth is this: if the first statement is not meant to be true in a univocal sense, then is it possible for the respondent to disagree with it? To agree? To even understand what is being said?
-Asytheta: truth as the conformity of thought and speech to reality (whose opposite is falsity); and
-Adiareta, truth as the grasping of a whole, apprehension (whose opposite is simply ignorance).
It is worth noting that Aquinas sees truth in a largely discursive manner:
In Ad Thalassium 60, St. Maximus the Confessor argues for the superiority of unified and direct experience, as opposed to discursive reasoning/knowing. Similarly, in Philosophiae Consolationis (4.6), Boethius argues that reason is to the intellect as time is to eternity, and what “circle” is to “center.” This is because it is “proper” for reason to be “diffused” (diffundi, i.e., scattered or spread) about many things, and then to gather from them a single cognition (i.e., unifying the “Many” into a “One”). Pseudo-Dionysius makes a similar point, (De Divinis Nominibus, 7.2) claiming that souls have rationality insofar as they “diffusedly encircle” (diffusiue circueunt) the truth of multiple existent things. Conversely, the intellect considers one simple truth and grasps the cognition of a whole multitude in it.
In proof of which we must consider that when anything is predicated of many things univocally, it is found in each of them according to its proper nature; as animal is found in each species of animal.
Exactly, and not all knowledge is discursive knowledge. It's a sad philosophy that has to look at the climax of Dante's Commedia in Canto XXXIII of the Paradisio, his appeals to the inadequacy of language and memory, and say "well he's just sputtering nonsense." And it's just as sad to have to say something like "we can appreciate the words but not its rational content," since the Comedy is one of the very best (IMO the best) instances of philosophy breathed into narrative form. — Count Timothy von Icarus
Faced with this result, it has a "slide into multiplicity" and produces a multitude of isolated truths, goods, and beauties, with each varying by culture, individual, or even context. — Count Timothy von Icarus
