1. Philosophy / C. History of Philosophy / 5. Modern Philosophy / c. Modern philosophy mid-period
In ontology, logic dominated language, until logic was mathematized [Badiou]
     Full Idea: From Aristotle to Hegel, logic was the philosophical category of ontology's dominion over language. The mathematization of logic has authorized language to become that which seizes philosophy for itself.
     From: Alain Badiou (Briefings on Existence [1998], 8)
1. Philosophy / D. Nature of Philosophy / 8. Humour
The female body, when taken in its entirety, is the Phallus itself [Badiou]
     Full Idea: The female body, when taken in its entirety, is the Phallus itself.
     From: Alain Badiou (Briefings on Existence [1998])
     A reaction: Too good to pass over, too crazy to file sensibly, too creepy to have been filed under humour, my candidate for the weirdest remark I have ever read in a serious philosopher, but no doubt if you read Lacan etc for long enough it looks deeply wise.
1. Philosophy / E. Nature of Metaphysics / 7. Against Metaphysics
Philosophy has been relieved of physics, cosmology, politics, and now must give up ontology [Badiou]
     Full Idea: Philosophy has been released from, even relieved of, physics, cosmology, and politics, as well as many other things. It is important for it to be released from ontology per se.
     From: Alain Badiou (Briefings on Existence [1998], 3)
     A reaction: A startling proposal, for anyone who thought that ontology was First Philosophy. Badiou wants to hand ontology over to mathematicians, but I am unclear what remains for the philosophers to do.
2. Reason / A. Nature of Reason / 1. On Reason
When questions are doubtful we should concentrate not on objects but on ideas of the intellect [Plato]
     Full Idea: Doubtful questions should not be discussed in terms of visible objects or in relation to them, but only with reference to ideas conceived by the intellect.
     From: Plato (Parmenides [c.364 BCE], 135e)
2. Reason / A. Nature of Reason / 4. Aims of Reason
Consensus is the enemy of thought [Badiou]
     Full Idea: Consensus is the enemy of thought.
     From: Alain Badiou (Briefings on Existence [1998], 2)
     A reaction: A nice slogan for bringing Enlightenment optimists to a halt. I am struck. Do I allow my own thinking to always be diverted towards something which might result in a consensus? Do I actually (horror!) prefer consensus to truth?
2. Reason / B. Laws of Thought / 5. Opposites
Opposites are as unlike as possible [Plato]
     Full Idea: Opposites are as unlike as possible.
     From: Plato (Parmenides [c.364 BCE], 159a)
2. Reason / C. Styles of Reason / 1. Dialectic
Plato's 'Parmenides' is the greatest artistic achievement of the ancient dialectic [Hegel on Plato]
     Full Idea: Plato's 'Parmenides' is the greatest artistic achievement of the ancient dialectic.
     From: comment on Plato (Parmenides [c.364 BCE]) by Georg W.F.Hegel - Phenomenology of Spirit Pref 71
     A reaction: It is a long way from the analytic tradition of philosophy to be singling out a classic text for its 'artistic' achievement. Eventually we may even look back on, say, Kripke's 'Naming and Necessity' and see it in that light.
3. Truth / C. Correspondence Truth / 1. Correspondence Truth
Correspondence could be with other beliefs, rather than external facts [Kusch]
     Full Idea: The correspondence theory of truth does not commit one to the view the reality is mind-independent. There is no reason why the 'facts' that correspond to true beliefs might not themselves be beliefs or ideas.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch.17)
     A reaction: This seems important, as it is very easy to assume that espousal of correspondence necessarily goes with realism about the external world. It is surprising to think that a full-blown Idealist might espouse the correspondence theory.
3. Truth / F. Semantic Truth / 1. Tarski's Truth / a. Tarski's truth definition
Tarskians distinguish truth from falsehood by relations between members of sets [Kusch]
     Full Idea: According to the Tarskians we separate out truths from falsehoods by tracing the relations between members of different sets.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch.16)
4. Formal Logic / F. Set Theory ST / 2. Mechanics of Set Theory / b. Terminology of ST
There is 'transivity' iff membership ∈ also means inclusion ⊆ [Badiou]
     Full Idea: 'Transitivity' signifies that all of the elements of the set are also parts of the set. If you have α∈Β, you also have α⊆Β. This correlation of membership and inclusion gives a stability which is the sets' natural being.
     From: Alain Badiou (Briefings on Existence [1998], 11)
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / j. Axiom of Choice IX
The axiom of choice must accept an indeterminate, indefinable, unconstructible set [Badiou]
     Full Idea: The axiom of choice actually amounts to admitting an absolutely indeterminate infinite set whose existence is asserted albeit remaining linguistically indefinable. On the other hand, as a process, it is unconstructible.
     From: Alain Badiou (Briefings on Existence [1998], 2)
     A reaction: If only constructible sets are admitted (see 'V = L') then there is a contradiction.
5. Theory of Logic / A. Overview of Logic / 1. Overview of Logic
Topos theory explains the plurality of possible logics [Badiou]
     Full Idea: Topos theory explains the plurality of possible logics.
     From: Alain Badiou (Briefings on Existence [1998], 14)
     A reaction: This will because logic will have a distinct theory within each 'topos'.
5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic
Logic is a mathematical account of a universe of relations [Badiou]
     Full Idea: Logic should first and foremost be a mathematical thought of what a universe of relations is.
     From: Alain Badiou (Briefings on Existence [1998], 14)
5. Theory of Logic / L. Paradox / 3. Antinomies
Plato found antinomies in ideas, Kant in space and time, and Bradley in relations [Plato, by Ryle]
     Full Idea: Plato (in 'Parmenides') shows that the theory that 'Eide' are substances, and Kant that space and time are substances, and Bradley that relations are substances, all lead to aninomies.
     From: report of Plato (Parmenides [c.364 BCE]) by Gilbert Ryle - Are there propositions? 'Objections'
Plato's 'Parmenides' is perhaps the best collection of antinomies ever made [Russell on Plato]
     Full Idea: Plato's 'Parmenides' is perhaps the best collection of antinomies ever made.
     From: comment on Plato (Parmenides [c.364 BCE]) by Bertrand Russell - The Principles of Mathematics §337
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / a. Numbers
Numbers are for measuring and for calculating (and the two must be consistent) [Badiou]
     Full Idea: Number is an instance of measuring (distinguishing the more from the less, and calibrating data), ..and a figure for calculating (one counts with numbers), ..and it ought to be a figure of consistency (the compatibility of order and calculation).
     From: Alain Badiou (Briefings on Existence [1998], 11)
There is no single unified definition of number [Badiou]
     Full Idea: Apparently - and this is quite unlike old Greek times - there is no single unified definition of number.
     From: Alain Badiou (Briefings on Existence [1998], 11)
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / b. Types of number
Each type of number has its own characteristic procedure of introduction [Badiou]
     Full Idea: There is a heterogeneity of introductory procedures of different classical number types: axiomatic for natural numbers, structural for ordinals, algebraic for negative and rational numbers, topological for reals, mainly geometric for complex numbers.
     From: Alain Badiou (Briefings on Existence [1998], 11)
Must we accept numbers as existing when they no longer consist of units? [Badiou]
     Full Idea: Do we have to confer existence on numbers whose principle is to no longer consist of units?
     From: Alain Badiou (Briefings on Existence [1998], 2)
     A reaction: This very nicely expresses what seems to me perhaps the most important question in the philosophy of mathematics. I am reluctant to accept such 'unitless' numbers, but I then feel hopelessly old-fashioned and naďve. What to do?
6. Mathematics / A. Nature of Mathematics / 5. The Infinite / g. Continuum Hypothesis
The undecidability of the Continuum Hypothesis may have ruined or fragmented set theory [Badiou]
     Full Idea: As we have known since Paul Cohen's theorem, the Continuum Hypothesis is intrinsically undecidable. Many believe Cohen's discovery has driven the set-theoretic project into ruin, or 'pluralized' what was once presented as a unified construct.
     From: Alain Badiou (Briefings on Existence [1998], 6)
     A reaction: Badiou thinks the theorem completes set theory, by (roughly) finalising its map.
6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / c. Nominalist structuralism
If mathematics is a logic of the possible, then questions of existence are not intrinsic to it [Badiou]
     Full Idea: If mathematics is a logic of the possible, then questions of existence are not intrinsic to it (as they are for the Platonist).
     From: Alain Badiou (Briefings on Existence [1998], 7)
     A reaction: See also Idea 12328. I file this to connect it with Hellman's modal (and nominalist) version of structuralism. Could it be that mathematics and modal logic are identical?
6. Mathematics / C. Sources of Mathematics / 1. Mathematical Platonism / a. For mathematical platonism
One is, so numbers exist, so endless numbers exist, and each one must partake of being [Plato]
     Full Idea: If one is, there must also necessarily be number - Necessarily - But if there is number, there would be many, and an unlimited multitude of beings. ..So if all partakes of being, each part of number would also partake of it.
     From: Plato (Parmenides [c.364 BCE], 144a)
     A reaction: This seems to commit to numbers having being, then to too many numbers, and hence to too much being - but without backing down and wondering whether numbers had being after all. Aristotle disagreed.
Platonists like axioms and decisions, Aristotelians like definitions, possibilities and logic [Badiou]
     Full Idea: A Platonist's interest focuses on axioms in which the decision of thought is played out, where an Aristotelian or Leibnizian interest focuses on definitions laying out the representation of possibilities (...and the essence of mathematics is logic).
     From: Alain Badiou (Briefings on Existence [1998], 7)
     A reaction: See Idea 12323 for the significance of the Platonist approach. So logicism is an Aristotelian project? Frege is not a true platonist? I like the notion of 'the representation of possibilities', so will vote for the Aristotelians, against Badiou.
6. Mathematics / C. Sources of Mathematics / 6. Logicism / d. Logicism critique
Logic is definitional, but real mathematics is axiomatic [Badiou]
     Full Idea: Logic is definitional, whereas real mathematics is axiomatic.
     From: Alain Badiou (Briefings on Existence [1998], 10)
7. Existence / A. Nature of Existence / 3. Being / a. Nature of Being
There is no Being as a whole, because there is no set of all sets [Badiou]
     Full Idea: The fundamental theorem that 'there does not exist a set of all sets' designates the inexistence of Being as a whole. ...A crucial consequence of this property is that any ontological investigation is irremediably local.
     From: Alain Badiou (Briefings on Existence [1998], 14)
     A reaction: The second thought pushes Badiou into Topos Theory, where the real numbers (for example) have a separate theory in each 'topos'.
7. Existence / A. Nature of Existence / 3. Being / b. Being and existence
Existence is Being itself, but only as our thought decides it [Badiou]
     Full Idea: Existence is precisely Being itself in as much as thought decides it. And that decision orients thought essentially. ...It is when you decide upon what exists that you bind your thought to Being.
     From: Alain Badiou (Briefings on Existence [1998], 2)
     A reaction: [2nd half p.57] Helpful for us non-Heideggerians to see what is going on. Does this mean that Being is Kant's noumenon?
7. Existence / A. Nature of Existence / 3. Being / c. Becoming
The one was and is and will be and was becoming and is becoming and will become [Plato]
     Full Idea: The one was and is and will be and was becoming and is becoming and will become.
     From: Plato (Parmenides [c.364 BCE], 155d)
7. Existence / A. Nature of Existence / 3. Being / f. Primary being
Plato's Parmenides has a three-part theory, of Primal One, a One-Many, and a One-and-Many [Plato, by Plotinus]
     Full Idea: The Platonic Parmenides is more exact [than Parmenides himself]; the distinction is made between the Primal One, a strictly pure Unity, and a secondary One which is a One-Many, and a third which is a One-and-Many.
     From: report of Plato (Parmenides [c.364 BCE]) by Plotinus - The Enneads 5.1.08
     A reaction: Plotinus approves of this three-part theory. Parmenides has the problem that the highest Being contains no movement. By placing the One outside Being you can give it powers which an existent thing cannot have. Cf the concept of God.
7. Existence / A. Nature of Existence / 3. Being / i. Deflating being
The modern view of Being comes when we reject numbers as merely successions of One [Badiou]
     Full Idea: The saturation and collapse of the Euclidean idea of the being of number as One's procession signs the entry of the thought of Being into modern times.
     From: Alain Badiou (Briefings on Existence [1998], 11)
     A reaction: That is, by allowing that not all numbers are built of units, numbers expand widely enough to embrace everything we think of as Being. The landmark event is the acceptance of the infinite as a number.
The primitive name of Being is the empty set; in a sense, only the empty set 'is' [Badiou]
     Full Idea: In Set Theory, the primitive name of Being is the void, the empty set. The whole hierarchy takes root in it. In a certain sense, it alone 'is'.
     From: Alain Badiou (Briefings on Existence [1998], 6)
     A reaction: This is the key to Badiou's view that ontology is mathematics. David Lewis pursued interesting enquiries in this area.
7. Existence / D. Theories of Reality / 1. Ontologies
Ontology is (and always has been) Cantorian mathematics [Badiou]
     Full Idea: Enlightened by the Cantorian grounding of mathematics, we can assert ontology to be nothing other than mathematics itself. This has been the case ever since its Greek origin.
     From: Alain Badiou (Briefings on Existence [1998], 1)
     A reaction: There seems to be quite a strong feeling among mathematicians that new 'realms of being' are emerging from their researches. Only a Platonist, of course, is likely to find this idea sympathetic.
7. Existence / D. Theories of Reality / 3. Reality
Absolute ideas, such as the Good and the Beautiful, cannot be known by us [Plato]
     Full Idea: The absolute good and the beautiful and all which we conceive to be absolute ideas are unknown to us.
     From: Plato (Parmenides [c.364 BCE], 134c)
8. Modes of Existence / D. Universals / 2. Need for Universals
You must always mean the same thing when you utter the same name [Plato]
     Full Idea: You must always mean the same thing when you utter the same name.
     From: Plato (Parmenides [c.364 BCE], 147d)
If you deny that each thing always stays the same, you destroy the possibility of discussion [Plato]
     Full Idea: If a person denies that the idea of each thing is always the same, he will utterly destroy the power of carrying on discussion.
     From: Plato (Parmenides [c.364 BCE], 135c)
8. Modes of Existence / D. Universals / 6. Platonic Forms / a. Platonic Forms
It would be absurd to think there were abstract Forms for vile things like hair, mud and dirt [Plato]
     Full Idea: Are there abstract ideas for such things as hair, mud and dirt, which are particularly vile and worthless? That would be quite absurd.
     From: Plato (Parmenides [c.364 BCE], 130d)
The concept of a master includes the concept of a slave [Plato]
     Full Idea: Mastership in the abstract is mastership of slavery in the abstract.
     From: Plato (Parmenides [c.364 BCE], 133e)
If admirable things have Forms, maybe everything else does as well [Plato]
     Full Idea: It is troubling that if admirable things have abstract ideas, then perhaps everything else must have ideas as well.
     From: Plato (Parmenides [c.364 BCE], 130d)
If absolute ideas existed in us, they would cease to be absolute [Plato]
     Full Idea: None of the absolute ideas exists in us, because then it would no longer be absolute.
     From: Plato (Parmenides [c.364 BCE], 133c)
Greatness and smallness must exist, to be opposed to one another, and come into being in things [Plato]
     Full Idea: These two ideas, greatness and smallness, exist, do they not? For if they did not exist, they could not be opposites of one another, and could not come into being in things.
     From: Plato (Parmenides [c.364 BCE], 149e)
Plato moves from Forms to a theory of genera and principles in his later work [Plato, by Frede,M]
     Full Idea: It seems to me that Plato in the later dialogues, beginning with the second half of 'Parmenides', wants to substitute a theory of genera and theory of principles that constitute these genera for the earlier theory of forms.
     From: report of Plato (Parmenides [c.364 BCE]) by Michael Frede - Title, Unity, Authenticity of the 'Categories' V
     A reaction: My theory is that the later Plato came under the influence of the brilliant young Aristotle, and this idea is a symptom of it. The theory of 'principles' sounds like hylomorphism to me.
8. Modes of Existence / D. Universals / 6. Platonic Forms / b. Partaking
Participation is not by means of similarity, so we are looking for some other method of participation [Plato]
     Full Idea: Participation is not by means of likeness, so we must seek some other method of participation.
     From: Plato (Parmenides [c.364 BCE], 133a)
Each idea is in all its participants at once, just as daytime is a unity but in many separate places at once [Plato]
     Full Idea: Just as day is in many places at once, but not separated from itself, so each idea might be in all its participants at once.
     From: Plato (Parmenides [c.364 BCE], 131b)
If things are made alike by participating in something, that thing will be the absolute idea [Plato]
     Full Idea: That by participation in which like things are made like, will be the absolute idea, will it not?
     From: Plato (Parmenides [c.364 BCE], 132e)
If things partake of ideas, this implies either that everything thinks, or that everything actually is thought [Plato]
     Full Idea: If all things partake of ideas, must either everything be made of thoughts and everything thinks, or everything is thought, and so can't think?
     From: Plato (Parmenides [c.364 BCE], 132c)
The whole idea of each Form must be found in each thing which participates in it [Plato]
     Full Idea: The whole idea of each form (of beauty, justice etc) must be found in each thing which participates in it.
     From: Plato (Parmenides [c.364 BCE], 131a)
8. Modes of Existence / D. Universals / 6. Platonic Forms / c. Self-predication
Nothing can be like an absolute idea, because a third idea intervenes to make them alike (leading to a regress) [Plato]
     Full Idea: It is impossible for anything to be like an absolute idea, because a third idea will appear to make them alike, and if that is like anything, it will lead to another idea, and so on.
     From: Plato (Parmenides [c.364 BCE], 133a)
If absolute greatness and great things are seen as the same, another thing appears which makes them seem great [Plato]
     Full Idea: If you regard the absolute great and the many great things in the same way, will not another appear beyond, by which all these must appear to be great?
     From: Plato (Parmenides [c.364 BCE], 132a)
9. Objects / B. Unity of Objects / 1. Unifying an Object / b. Unifying aggregates
Parts must belong to a created thing with a distinct form [Plato]
     Full Idea: The part would not be the part of many things or all, but of some one character ['ideas'] and of some one thing, which we call a 'whole', since it has come to be one complete [perfected] thing composed [created] of all.
     From: Plato (Parmenides [c.364 BCE], 157d)
     A reaction: A serious shot by Plato at what identity is. Harte quotes it (125) and shows that 'character' is Gk 'idea', and 'composed' will translate as 'created'. 'Form' links this Platonic passage to Aristotle's hylomorphism.
9. Objects / C. Structure of Objects / 5. Composition of an Object
In Parmenides, if composition is identity, a whole is nothing more than its parts [Plato, by Harte,V]
     Full Idea: At the heart of the 'Parmenides' puzzles about composition is the thesis that composition is identity. Considered thus, a whole adds nothing to an ontology that already includes its parts
     From: report of Plato (Parmenides [c.364 BCE]) by Verity Harte - Plato on Parts and Wholes 2.5
     A reaction: There has to be more to a unified identity that mere proximity of the parts. When do parts come together, and when do they actually 'compose' something?
9. Objects / C. Structure of Objects / 8. Parts of Objects / a. Parts of objects
Plato says only a one has parts, and a many does not [Plato, by Harte,V]
     Full Idea: In 'Parmenides' it is argued that a part cannot be part of a many, but must be part of something one.
     From: report of Plato (Parmenides [c.364 BCE], 157c) by Verity Harte - Plato on Parts and Wholes 3.2
     A reaction: This looks like the right way to go with the term 'part'. We presuppose a unity before we even talk of its parts, so we can't get into contradictions and paradoxes about their relationships.
Anything which has parts must be one thing, and parts are of a one, not of a many [Plato]
     Full Idea: The whole of which the parts are parts must be one thing composed of many; for each of the parts must be part, not of a many, but of a whole.
     From: Plato (Parmenides [c.364 BCE], 157c)
     A reaction: This is a key move of metaphysics, and we should hang on to it. The other way madness lies.
9. Objects / C. Structure of Objects / 8. Parts of Objects / c. Wholes from parts
It seems that the One must be composed of parts, which contradicts its being one [Plato]
     Full Idea: The One must be composed of parts, both being a whole and having parts. So on both grounds the One would thus be many and not one. But it must be not many, but one. So if the One will be one, it will neither be a whole, nor have parts.
     From: Plato (Parmenides [c.364 BCE], 137c09), quoted by Kathrin Koslicki - The Structure of Objects 5.2
     A reaction: This is the starting point for Plato's metaphysical discussion of objects. It seems to begin a line of thought which is completed by Aristotle, surmising that only an essential structure can bestow identity on a bunch of parts.
9. Objects / F. Identity among Objects / 6. Identity between Objects
Two things relate either as same or different, or part of a whole, or the whole of the part [Plato]
     Full Idea: Everything is surely related to everything as follows: either it is the same or different; or, if it is not the same or different, it would be related as part to whole or as whole to part.
     From: Plato (Parmenides [c.364 BCE], 146b)
     A reaction: This strikes me as a really helpful first step in trying to analyse the nature of identity. Two things are either two or (actually) one, or related mereologically.
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
We can have knowledge without belief, if others credit us with knowledge [Kusch]
     Full Idea: We can have knowledge that p without believing that p. It is enough that others credit us with the knowledge.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 5)
     A reaction: [He is discussing Welbourne 1993] This is an extreme of the communitarian view.
11. Knowledge Aims / C. Knowing Reality / 4. Solipsism
Methodological Solipsism assumes all ideas could be derived from one mind [Kusch]
     Full Idea: 'Methodological solipsism' says merely that everyone can conceive of themselves as the only subject. Everyone can construct all referents of their thought and talk out of complexes of their very own experience.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch.19)
     A reaction: The possibility of this can be denied (e.g. by Putnam 1983, dating back to Wittgenstein). I too would doubt it, though finding a good argument seems a forlorn hope.
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / f. Foundationalism critique
Foundations seem utterly private, even from oneself at a later time [Kusch]
     Full Idea: Foundationalists place the foundations of knowledge at a point where they are in principle accessible only to the individual knower. They cannot be 'shared' with another person, or with oneself at a later time.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 8)
     A reaction: Kusch is defending an extremely social view of knowledge. Being private to an individual may just he an unfortunate epistemological fact. Being unavailable even to one's later self seems a real problem for foundational certainty.
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / a. Coherence as justification
Testimony is reliable if it coheres with evidence for a belief, and with other beliefs [Kusch]
     Full Idea: Testimony must be reliable since its deliveries cohere both with input from other information routes in the formation of single beliefs, and with other types of beliefs in the formation of systems of belief.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 4)
     A reaction: Kusch criticises this view (credited to C.A.J. Coady 1992) as too individualistic , but it sounds to me dead right. I take a major appeal of the coherence account of justification to be its capacity to extend seamlessly out into external testimony.
The coherentist restricts the space of reasons to the realm of beliefs [Kusch]
     Full Idea: The coherentist restricts the space of reasons to the realm of beliefs.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 8)
     A reaction: I endorse this idea, which endorses Davidson's slogan on the subject. The key thought is that a 'pure' sensation is uninterpreted, and so cannot justify anything. It is only once it generates a proposition that it can justify. But McDowell 1994.
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / c. Coherentism critique
Individualistic coherentism lacks access to all of my beliefs, or critical judgement of my assessment [Kusch]
     Full Idea: Individualistic versions of coherentism assume that a belief is justified if it fits with all, or most, of my contemporaneous beliefs. But who has access to that totality? Who can judge my assessment? From what position could it be judged?
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 8)
     A reaction: [compressed] Though I agree with Kusch on the social aspect of coherence, I don't think these are major criticisms. Who can access, or critically evaluate a society's body of supposedly coherent beliefs? We just do our best.
Individual coherentism cannot generate the necessary normativity [Kusch]
     Full Idea: Standard forms of coherentism are unable to account for normativity, because of their common individualism. Normativity cannot be generated within the isolated individual, or in the causal interaction between world and individual mind.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch.10)
     A reaction: This thought leads to belief in rationalism and the a priori, not (as Kusch hopes) to the social dimension. How can social normativity get off the ground if there is none of it to be found in individuals? The criteria of coherence seem to be given.
13. Knowledge Criteria / C. External Justification / 2. Causal Justification
Cultures decide causal routes, and they can be critically assessed [Kusch]
     Full Idea: Assessments of causal routes are specific to cultures, and thus not beyond dialectical justification.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch.11)
     A reaction: This is a good defence of the social and communitarian view against those who are trying to be thoroughly naturalistic and physicalist by relying entirely on causal processes for all explanation, even though I sympathise with such naturalism.
13. Knowledge Criteria / C. External Justification / 3. Reliabilism / a. Reliable knowledge
Process reliabilism has been called 'virtue epistemology', resting on perception, memory, reason [Kusch]
     Full Idea: Process reliabilism is sometimes subsumed under the label 'virtue epistemology', so that processes are 'epistemically virtuous' if they lead mostly to true beliefs. The 'intellectual virtues' here are perception, memory or reasoning.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 9)
     A reaction: I am shocked that 'intellectual virtue' should be hijacked by reliabilists, suggesting that it even applies to a good clock. I like the Aristotelian idea that sound knowledge rests on qualities of character in the knower - including social qualities.
13. Knowledge Criteria / C. External Justification / 6. Contextual Justification / a. Contextualism
Justification depends on the audience and one's social role [Kusch]
     Full Idea: How a claim (about an X-ray) needs to be justified depends on whether one is confronted by a group of laypersons, or of experts, and is prescribed by one's social role.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 8)
     A reaction: I think this is exactly right. I cannot think of any absolute criterion for justification which doesn't play straight into the hands of sceptics. Final and certain justification is an incoherent notion. But I am a little more individualistic than Kusch.
13. Knowledge Criteria / C. External Justification / 7. Testimony
Testimony is an area in which epistemology meets ethics [Kusch]
     Full Idea: Testimony is an area in which epistemology meets ethics.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 5)
     A reaction: This is very thought-provoking. A key concept linking the two would be 'respect'. Consider also 'experts'.
Powerless people are assumed to be unreliable, even about their own lives [Kusch]
     Full Idea: The powerless in society are not usually taken to be trustworthy witnesses even when it comes to providing information about their own lives.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 5)
     A reaction: This is where epistemology shades off into politics and the writings of Foucault.
Testimony does not just transmit knowledge between individuals - it actually generates knowledge [Kusch]
     Full Idea: Testimony is not just a means of transmission of complete items of knowledge from and to an individual. Testimony is almost always generative of knowledge.
     From: Martin Kusch (Knowledge by Agreement [2002], Intro)
     A reaction: I'm not clear how my testimony could fail to be knowledge for me, but become knowledge just because I pass it to you. I might understand what I say better than you did. When fools pool their testimony, presumably not much knowledge results.
Some want to reduce testimony to foundations of perceptions, memories and inferences [Kusch]
     Full Idea: Reductionalists about testimony are foundationalists by temperament. ...Their project amounts to justifying our testimonial beliefs in terms of perceptions, memories and inferences.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 4)
     A reaction: Kusch wants to claim that the sharing of testimony is the means by which knowledge is created. My line is something like knowledge being founded on a social coherence, which is an extension of internal individual coherence.
Testimony won't reduce to perception, if perception depends on social concepts and categories [Kusch]
     Full Idea: How can we hope to reduce testimony to perception if the way we perceive the world is to a considerable extent shaped by concepts and categories that we have learned from others?
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 4)
     A reaction: To me this sounds like good support for coherentism, the benign circle between my reason, my experience, and the testimony and reason of others. Asking how the circle could get started shows ignorance of biology.
A foundation is what is intelligible, hence from a rational source, and tending towards truth [Kusch]
     Full Idea: It can be argued that testimony is non-reductive because it relies on the fact that whatever is intelligible is likely to come from a rational source, and that rational sources, by their very nature, tend towards the truth.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 4 n7)
     A reaction: [He cites Tyler Burge 1993, 1997] If this makes testimony non-reductive, how would one assess whether the testimony is 'intelligible'?
Vindicating testimony is an expression of individualism [Kusch]
     Full Idea: To believe that testimony needs a general vindication is itself an expression of individualism.
     From: Martin Kusch (Knowledge by Agreement [2002], Intro)
     A reaction: Kusch is a spokesman for Communitarian Epistemology. Surely we are allowed to identify the criteria for what makes a good witness? Ask a policeman.
13. Knowledge Criteria / C. External Justification / 8. Social Justification
Myths about lonely genius are based on epistemological individualism [Kusch]
     Full Idea: Many myths about the lonely scientific genius underwrite epistemological individualism.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 5)
     A reaction: They all actually say that they 'stood on the shoulders of giants', and they are invariably immersed in the contemporary researches of teams of like-minded people. How surprised were the really expert contemporaries by Newton, Einstein, Gödel?
Communitarian Epistemology says 'knowledge' is a social status granted to groups of people [Kusch]
     Full Idea: I propose 'communitarian epistemology' - claiming first that the term 'knowledge' marks a social status, and is dependent on the existence of communities, and second that this social status is typically granted to groups of people.
     From: Martin Kusch (Knowledge by Agreement [2002], Intro)
     A reaction: I find this very congenial, though Kusch goes a little far when he claims that knowledge is largely created by social groups. He allows that Robinson Crusoe might have knowledge of his island, but can't give a decent account of it.
Private justification is justification to imagined other people [Kusch]
     Full Idea: Coming to convince myself is actually to form a pretend communal belief with pretend others, ..which is clearly parasitic on the case where the others are real.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch.11)
     A reaction: This slightly desperate move is a way for 'communitarian' epistemologists to deal with Robinson Crusoe cases. I think Kusch is right, but it is a bit hard to prove that this is what is 'actually' going on.
16. Persons / E. Rejecting the Self / 2. Self as Social Construct
To be considered 'an individual' is performed by a society [Kusch]
     Full Idea: One cannot even have the social status of 'being an individual' unless it has been conferred on one by a communal performative belief.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch.11)
     A reaction: This sounds crazy until you think of the mentality of a tenth generation slave in a fully slave-owning society.
18. Thought / D. Concepts / 1. Concepts / a. Nature of concepts
Our experience may be conceptual, but surely not the world itself? [Kusch]
     Full Idea: I am unconvinced by McDowell's arguments in favour of treating the world as itself conceptual. Granted that our experience is conceptual in quality; it still does not follow that the world itself is conceptual.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 9)
     A reaction: I would take Kusch's point to be a given in any discussion of concepts, and McDowell as a non-starter on this one. I am inclined to believe that we do have non-conceptual experiences, but I take them to be epistemologically useless.
19. Language / F. Communication / 1. Rhetoric
Often socialising people is the only way to persuade them [Kusch]
     Full Idea: Often we can convince members of other cultures only by socializing them into our culture.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch.19)
     A reaction: This looks both true and interesting, and is good support for Kusch's communitarian epistemology. What actually persuades certainly doesn't have to be reasons, and may be almost entirely social.
19. Language / F. Communication / 3. Denial
We must either assert or deny any single predicate of any single subject [Badiou]
     Full Idea: There can be nothing intermediate to an assertion and a denial. We must either assert or deny any single predicate of any single subject.
     From: Alain Badiou (Briefings on Existence [1998], 1011b24)
     A reaction: The first sentence seems to be bivalence, and the second sentence excluded middle.
24. Political Theory / D. Ideologies / 7. Communitarianism / a. Communitarianism
Communitarianism in epistemology sees the community as the primary knower [Kusch]
     Full Idea: Communitarianism in epistemology sees the community as the primary knower.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 5)
     A reaction: This thought offers an account of epistemology which could fit in with communitarian political views. See the ideas of Martin Kusch in this database.
25. Social Practice / E. Policies / 2. Religion in Society
For Enlightenment philosophers, God was no longer involved in politics [Badiou]
     Full Idea: For the philosophers of the Enlightenment politics is strictly the affair of humankind, an immanent practice from which recourse to the All Mighty's providential organization had to be discarded.
     From: Alain Badiou (Briefings on Existence [1998], Prol)
25. Social Practice / E. Policies / 5. Education / c. Teaching
Only a great person can understand the essence of things, and an even greater person can teach it [Plato]
     Full Idea: Only a man of very great natural gifts will be able to understand that everything has a class and absolute essence, and an even more wonderful man can teach this.
     From: Plato (Parmenides [c.364 BCE], 135a)
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / d. The unlimited
The unlimited has no shape and is endless [Plato]
     Full Idea: The unlimited partakes neither of the round nor of the straight, because it has no ends nor edges.
     From: Plato (Parmenides [c.364 BCE], 137e)
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / e. The One
Some things do not partake of the One [Plato]
     Full Idea: The others cannot partake of the one in any way; they can neither partake of it nor of the whole.
     From: Plato (Parmenides [c.364 BCE], 159d)
     A reaction: Compare Idea 231
The only movement possible for the One is in space or in alteration [Plato]
     Full Idea: If the One moves it either moves spatially or it is altered, since these are the only motions.
     From: Plato (Parmenides [c.364 BCE], 138b)
Everything partakes of the One in some way [Plato]
     Full Idea: The others are not altogether deprived of the one, for they partake of it in some way.
     From: Plato (Parmenides [c.364 BCE], 157c)
     A reaction: Compare Idea 233.
26. Natural Theory / B. Natural Kinds / 7. Critique of Kinds
Natural kinds are social institutions [Kusch]
     Full Idea: Natural kinds are social institutions.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch.11)
     A reaction: I can see what he means, but I take this to be deeply wrong. A clarification of what exactly is meant by a 'natural kind' is needed before we can make any progress with this one. Is a village a natural kind? Or a poodle? Or a shoal?
28. God / A. Divine Nature / 4. Divine Contradictions
Omniscience is incoherent, since knowledge is a social concept [Kusch]
     Full Idea: The very idea of omniscience is dubious, at least for the communitarian epistemologist, since knowing is a social state, and knowledge is a social status, needing a position in a social network.
     From: Martin Kusch (Knowledge by Agreement [2002], Ch. 4)
     A reaction: A nice test case. Would an omniscient mind have evidence for its beliefs? Would it continually check for coherence? Is it open to criticism? Does it even entertain the possibility of error? Could another 'omniscient' mind challenge it?
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
We couldn't discuss the non-existence of the One without knowledge of it [Plato]
     Full Idea: There must be knowledge of the one, or else not even the meaning of the words 'if the one does not exist' would be known.
     From: Plato (Parmenides [c.364 BCE], 160d)
29. Religion / D. Religious Issues / 1. Religious Commitment / a. Religious Belief
The God of religion results from an encounter, not from a proof [Badiou]
     Full Idea: The God of metaphysics makes sense of existing according to a proof, while the God of religion makes sense of living according to an encounter
     From: Alain Badiou (Briefings on Existence [1998], Prol)
