1606 | You have to be a Platonist to debate about reality, so every philosopher is a Platonist [Roochnik] |
Full Idea: Everyone who enters into a debate about reality automatically becomes a Platonist. Since such debates are the essence of philosophy, every philosopher is a Platonist. | |
From: David Roochnik (The Tragedy of Reason [1990], p.199) | |
A reaction: This is correct |
1595 | Philosophy aims to satisfy the chief human desire - the articulation of beauty itself [Roochnik] |
Full Idea: Philosophy, the attempt to articulate the vision of beauty itself, is the attempt to satisfy the highest human desire. | |
From: David Roochnik (The Tragedy of Reason [1990], p.120) | |
A reaction: A million miles away from modern philosophy, but still an ideal to be taken seriously. |
1571 | 'Logos' ranges from thought/reasoning, to words, to rational structures outside thought [Roochnik] |
Full Idea: Logos can mean i) a thought or reasoning, ii) the word which expresses a thought, iii) a rational structure outside human thought. These meanings give 'logos' an extraordinary range. | |
From: David Roochnik (The Tragedy of Reason [1990], Intro. 12) |
1573 | The hallmark of a person with logos is that they give reasons why one opinion is superior to another [Roochnik] |
Full Idea: What is supposed to identify the person of logos from the one without is the commitment to giving reasons explaining why one opinion is superior to another. | |
From: David Roochnik (The Tragedy of Reason [1990], Intro. 17) |
1603 | Logos is not unconditionally good, but good if there is another person willing to engage with it [Roochnik] |
Full Idea: Logos is not unconditionally good, but good contingent on there being some other person (out there) who is willing to talk with logos, to approach it even as an opponent. | |
From: David Roochnik (The Tragedy of Reason [1990], p.175) |
1572 | In the seventeenth century the only acceptable form of logos was technical knowledge [Roochnik] |
Full Idea: In the seventeenth century only a certain type of logos was deemed legitimate, namely that identified with technical knowledge (or 'techné'). | |
From: David Roochnik (The Tragedy of Reason [1990], Intro. 15) |
1593 | Human desire has an ordered structure, with logos at the pinnacle [Roochnik] |
Full Idea: Human desire has an ordered structure, with logos at the pinnacle. | |
From: David Roochnik (The Tragedy of Reason [1990], p.109) |
1592 | Logos cannot refute the relativist, and so must admit that it too is a matter of desire (for truth and agreement) [Roochnik] |
Full Idea: Logos cannot refute the radical, consistent and self-conscious relativist. Therefore it must admit that, like the relativist, it itself is essentially a matter of desire. It wants to say what is right and wrong, true and false, and for others to agree. | |
From: David Roochnik (The Tragedy of Reason [1990], p.108) |
1598 | We prefer reason or poetry according to whether basics are intelligible or not [Roochnik] |
Full Idea: Is the arché (basis) intelligible, or is it chaos? Upon this question hinges all, for answering it determines whether poetry or logos is the form of human speech that best does justice to the world. | |
From: David Roochnik (The Tragedy of Reason [1990], p.139) |
23277 | Modern pragmatism sees objectivity as possible, despite its gradual evolution [Misak] |
Full Idea: One of the pillars of the new pragmatism is the thought that the standards of objectivity come into being and evolve over time, but that being historically situated in this way does not detract from their objectivity. | |
From: Cheryl Misak (Introduction to 'New Pragmatists' [2007], p.2) | |
A reaction: This looks to me like pragmatism finally coming to its senses. I would say that being any sort of 'social construct' (beloved of cultural relativists) in no way detracts from its capacity for objectivity and truth. |
1584 | Modern science, by aiming for clarity about the external world, has abandoned rationality in the human world [Roochnik] |
Full Idea: The modern scientific world view, with all its hope for clarity and precision, has a flipside, …which is its abandonment of rationality in the world of human significance. | |
From: David Roochnik (The Tragedy of Reason [1990], p.74) |
1591 | Unfortunately for reason, argument can't be used to establish the value of argument [Roochnik] |
Full Idea: Unfortunately for the logos there is no argument that can, without begging the question, establish the goodness of argumentation. | |
From: David Roochnik (The Tragedy of Reason [1990], p.106) |
1599 | Attempts to suspend all presuppositions are hopeless, because a common ground must be agreed for the process [Roochnik] |
Full Idea: To debate about suspending all our presuppositions requires a common ground which, upon being established, immediately renders the debate superfluous. | |
From: David Roochnik (The Tragedy of Reason [1990], p.144) |
19100 | Truth makes disagreements matter, or worth settling [Misak] |
Full Idea: The role of truth is to make disagreements matter, or to make sense of wanting to resolve disagreements. | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 2) | |
A reaction: [She cites Huw Price 2003] This suggests that the most important use of 'truth' is forensic. It is hard to make any sense of a law court without a robust sense of truth. Trial by jury, rather than some great personage, shows this value. |
19108 | Truth is proper assertion, but that has varying standards [Misak] |
Full Idea: The pragmatist will say that truth is proper assertion, but different discourses have different standards for proper assertion. | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 4) | |
A reaction: This remark shows that there is a pragmatic attitude towards truth behind most attempts to analyse the concept of assertion. When and why is assertion legitimate, and what motivates it? |
19094 | For pragmatists the loftiest idea of truth is just a feature of what remains forever assertible [Misak] |
Full Idea: For pragmatists there is an unseverable connection between making an assertion and claiming that it is true. ...Were we to get to a belief that is forever assertible...then we would have a true belief. There is nothing higher or better we could ask of it. | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 1) | |
A reaction: She is particularly drawing on Peirce. She says his 'ideal end of enquiry' idea is a small aspect of his view of truth, which is mainly given here. I had taken the pragmatic view of truth to be silly, but I may rethink. |
19099 | 'True' is used for emphasis, clarity, assertion, comparison, objectivity, meaning, negation, consequence... [Misak] |
Full Idea: 'P is true' is used to emphasise p, and avoid logic problems. The pragmatists says there are plenty of other uses: the aim of assertion or deliberation, the improvement of our views, distinguishing objectivity, explaining meaning, negation, consequence... | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 2) | |
A reaction: Pragmatism seems to break 'true' down into its many uses, rather than having a specific theory of truth. This might be where ordinary language philosophy (how is the word 'true' used) meets pragmatism (how is the concept [true] used). |
19103 | 'That's true' doesn't just refer back to a sentence, but implies sustained evidence for it [Misak] |
Full Idea: The pragmatist says 'That's so' or 'that's true' are not just 'pro-sentential', but carry with them the thought that evidence does currently speak in favour of the statement asserted, and the prediction that it will continue to speak in favour. | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 3) | |
A reaction: This is a very nice point made by a pragmatist against the flimsy view of truth held by various deflationary views. You ought to believe what is true, and stand by what you hold to be true. |
19105 | Truth isn't a grand elusive property, if it is just the aim of our assertions and inquiries [Misak] |
Full Idea: If truth is what satisfies our aims in first-order assertion and inquiry (as the pragmatist says), then there is no search for an elusive property, or a metaphysical property, or a property which we cannot grasp. | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 3) | |
A reaction: This pragmatic approach is much more persuasive than the usual caricature of pragmatic truth (Idea 19097), but I'm beginning to wonder how you distinguish an 'inquiry' (or 'assertion') from other modes of thought. Do I smell a circularity? |
19101 | Disquotation is bivalent [Misak] |
Full Idea: The disquotational schema entails bivalence. | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 2 n10) | |
A reaction: A simple but interesting observation. Critics of Tarski observe that he depends on a bivalent logic. |
19096 | Disquotationalism resembles a telephone directory [Misak] |
Full Idea: Disquotationalism is more like a telephone directory than a theory. | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 2 n7) | |
A reaction: [She cites Wilfred Sellars 1962:33] The idea is that there is a schema - 'p' is true iff p - and that all the acceptable sentences of a language can be expressed in this way, making a vast but finite list. It seems to replace 'theories'. |
19106 | Disquotations says truth is assertion, and assertion proclaims truth - but what is 'assertion'? [Misak] |
Full Idea: The point of the disquotational schema is that to say that a sentence is true is to assert it, and to assert a sentence is to say that it is true. We must then ask what it is to assert or endorse a proposition. | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 4) | |
A reaction: [She is referring to the views of Crispin Wright] Most people would say that we assert something because we think it is true, and truth is obviously prior. Clearly if it has been asserted, that was because someone thought it was true. |
19098 | Deflating the correspondence theory doesn't entail deflating all the other theories [Misak] |
Full Idea: We must not move seamlessly from the thought that the correspondence theory must be deflated to the thought that any theory of truth must be deflated. | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 2) | |
A reaction: This rather good essay offers the idea that Peircean pragmatic approaches to truth can meet the deflationary desires of the opponents of correspondence, without jettisoning all the crucial naturalistic connections with reality. Interesting. |
19104 | Deflationism isn't a theory of truth, but an account of its role in natural language [Misak] |
Full Idea: Deflationist theories are not theories of truth, or theories of what truth is. ...They are theories which try to explain the role that 'true' plays in natural languages. | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 3) | |
A reaction: [She cites Dorothy Grover 2001,2002] If so, then the modern axiomatic theory of truth sounds appealing, because it tries to give a fuller and more precise account than a mere list is disquotations could possibly give. |
15375 | If terms change their designations in different states, they are functions from states to objects [Fitting] |
Full Idea: The common feature of every designating term is that designation may change from state to state - thus it can be formalized by a function from states to objects. | |
From: Melvin Fitting (Intensional Logic [2007], 3) | |
A reaction: Specifying the objects sounds OK, but specifying states sounds rather tough. |
15376 | Intensional logic adds a second type of quantification, over intensional objects, or individual concepts [Fitting] |
Full Idea: To first order modal logic (with quantification over objects) we can add a second kind of quantification, over intensions. An intensional object, or individual concept, will be modelled by a function from states to objects. | |
From: Melvin Fitting (Intensional Logic [2007], 3.3) |
15378 | Awareness logic adds the restriction of an awareness function to epistemic logic [Fitting] |
Full Idea: Awareness logic enriched Hintikka's epistemic models with an awareness function, mapping each state to the set of formulas we are aware of at that state. This reflects some bound on the resources we can bring to bear. | |
From: Melvin Fitting (Intensional Logic [2007], 3.6.1) | |
A reaction: [He cites Fagin and Halpern 1988 for this] |
15379 | Justication logics make explicit the reasons for mathematical truth in proofs [Fitting] |
Full Idea: In justification logics, the logics of knowledge are extended by making reasons explicit. A logic of proof terms was created, with a semantics. In this, mathematical truths are known for explicit reasons, and these provide a measure of complexity. | |
From: Melvin Fitting (Intensional Logic [2007], 3.6.1) |
11026 | Classical logic is deliberately extensional, in order to model mathematics [Fitting] |
Full Idea: Mathematics is typically extensional throughout (we write 3+2=2+3 despite the two terms having different meanings). ..Classical first-order logic is extensional by design since it primarily evolved to model the reasoning of mathematics. | |
From: Melvin Fitting (Intensional Logic [2007], §1) |
11028 | λ-abstraction disambiguates the scope of modal operators [Fitting] |
Full Idea: λ-abstraction can be used to abstract and disambiguate a predicate. De re is [λx◊P(x)](f) - f has the possible-P property - and de dicto is ◊[λxP(x)](f) - possibly f has the P-property. Also applies to □. | |
From: Melvin Fitting (Intensional Logic [2007], §3.3) | |
A reaction: Compare the Barcan formula. Originated with Church in the 1930s, and Carnap 1947, but revived by Stalnaker and Thomason 1968. Because it refers to the predicate, it has a role in intensional versions of logic, especially modal logic. |
1605 | Reality can be viewed neutrally, or as an object of desire [Roochnik] |
Full Idea: There are two extremes: the Aristotelian views reality simply as reality, and the sophist or poet view reality only as an object of desire. | |
From: David Roochnik (The Tragedy of Reason [1990], p.199) |
19109 | The anti-realism debate concerns whether indefeasibility is a plausible aim of inquiry [Misak] |
Full Idea: If indefeasibility turns out to be something we can't sensibly aim at in a kind of inquiry, then the judgements that arise from that kind of 'inquiry' are not truth-apt. It is here that the realism/anti-realism debate resides. | |
From: Cheryl Misak (Pragmatism and Deflationism [2007], 4) | |
A reaction: A very interesting way of presenting the issue, one that makes the debate sound (to me) considerably more interesting than hitherto. I may start using the word 'indefeasible' rather a lot, in my chats with the anti-realist philosophical multitude. |
15377 | Definite descriptions pick out different objects in different possible worlds [Fitting] |
Full Idea: Definite descriptions pick out different objects in different possible worlds quite naturally. | |
From: Melvin Fitting (Intensional Logic [2007], 3.4) | |
A reaction: A definite description can pick out the same object in another possible world, or a very similar one, or an object which has almost nothing in common with the others. |
1577 | Relativism is a disease which destroys the possibility of rational debate [Roochnik] |
Full Idea: Relativism is disease, is pollution, for it negates the efficacy of logos. It destroys the possibility of a complete rational debate of fundamental questions. | |
From: David Roochnik (The Tragedy of Reason [1990], p.41) |
1596 | Reasoning aims not at the understanding of objects, but at the desire to give beautiful speeches [Roochnik] |
Full Idea: Logos originates not in a cognitive capacity for the apprehension of objects, but in the desire to give birth to beautiful speeches. | |
From: David Roochnik (The Tragedy of Reason [1990], p.124) | |
A reaction: It is hard for us to grasp this, but it might be quite life-enhancing if we could return to that old way of thought. |
1578 | If relativism is the correct account of human values, then rhetoric is more important than reasoning [Roochnik] |
Full Idea: If relativism offers an accurate description of human values, then rhetoric replaces logos as the most fundamental human activity. | |
From: David Roochnik (The Tragedy of Reason [1990], p.47) | |
A reaction: Or putting it another way, logos (reason) becomes meaningless. I suppose, though, that a relativist can conduct conditional reasoning (but must belief in some rules of reason). |
