Forms are said to be substances to which nothing is prior [Aristotle]
8. Modes of Existence / D. Universals / 6. Platonic Forms / b. Partaking
How can the Forms both be the substance of things and exist separately from them? [Aristotle]
If you accept Forms, you must accept the more powerful principle of 'participating' in them [Aristotle]
If partaking explains unity, what causes participating, and what is participating? [Aristotle]
There is a confusion because Forms are said to be universal, but also some Forms are separable and particular [Aristotle]
8. Modes of Existence / D. Universals / 6. Platonic Forms / c. Self-predication
Forms have to be their own paradigms, which seems to fuse the paradigm and the copy [Aristotle]

All attempts to prove the Forms are either invalid, or prove Forms where there aren't supposed to be any [Aristotle]
Are there forms for everything, or for negations, or for destroyed things? [Aristotle]
If men exist by participating in two forms (Animal and Biped), they are plural, not unities [Aristotle]
Aristotle is not asserting facts about the location of properties, but about their ontological status [Aristotle, by Moreland]

Some things are unified by their account, which rests on a unified thought about the thing [Aristotle]
9. Objects / B. Unity of Objects / 2. Substance / a. Substance
Substance is prior in being separate, in definition, and in knowledge [Aristotle, by Witt]
It is wrong to translate 'ousia' as 'substance' [Aristotle, by Politis]
The baffling question of what exists is asking about the nature of substance [Aristotle]
'Ousia' is 'primary being' not 'primary substance' [Aristotle, by Politis]
If substance is the basis of reality, then philosophy aims to understand substance [Aristotle]
The Pre-Socratics were studying the principles, elements and causes of substance [Aristotle]
A substance could exist as a subject, but not as a mere predicate [Kant]

Elements and physical objects are substances, but ideas and mathematics are not so clear [Aristotle]
9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined
It is matter that turns out to be substance [ousia] [Aristotle]
Substance [ousia] is the subject of predication and cause [aitia?] of something's existence [Aristotle]
Essence (fixed by definition) is also 'ousia', so 'ousia' is both ultimate subject, and a this-thing [Aristotle]
A substance is what-it-is-to-be, or the universal, or the genus, or the subject of saying [Aristotle]
Matter is not substance, because substance needs separability and thisness [Aristotle]
The substance is the form dwelling in the object [Aristotle]
Substance is unified and universals are diverse, so universals are not substance [Aristotle, by Witt]
A thing's substance is its primary cause of being [Aristotle]
None of the universals can be a substance [Aristotle]
In Aristotle, 'proté ousia' is 'primary being', and 'to hupokeimenon' is 'that which lies under' (or 'substance') [Aristotle, by Politis]
Substance is distinct being because of its unity [Aristotle, by Witt]
All appearances need substance, as that which persists through change [Kant]
Substance must exist, as the persisting substratum of the process of change [Kant]

Primary matter and form make a unity, one in potentiality, the other in actuality [Aristotle]
9. Objects / C. Structure of Objects / 2. Hylomorphism / a. Hylomorphism
The form of a thing is its essence and its primary being [Aristotle]
Plato says changing things have no essence; Aristotle disagrees [Aristotle, by Politis]
In 'Metaphysics' Z substantial primacy (as form) is explanatory rather than ontological [Aristotle, by Wedin]
In 'Metaphysics' substantial forms take over from objects as primary [Aristotle, by Frede,M]
Essential form is neither accidental nor necessary to matter, so it appears not to be a property [Aristotle, by Witt]
Aristotle's cosmos is ordered by form, and disordered by matter [Aristotle, by Gill,ML]
Aristotle moved from realism to nominalism about substances [Aristotle, by Frede,M]
A substance is a proper subject because the matter is a property of the form, not vice versa [Aristotle, by Gill,ML]
Aristotle doesn't think essential properties are those which must belong to a thing [Aristotle, by Kung]
Forms of sensible substances include unrealised possibilities, so are not fully actual [Aristotle, by Frede,M]
Essences are not properties (since those can't cause individual substances) [Aristotle, by Witt]
9. Objects / C. Structure of Objects / 2. Hylomorphism / b. Form as principle
Some forms, such as the Prime Mover, are held by Aristotle to exist without matter [Aristotle, by Gill,ML]
A true substance is constituted by some nature, which is a principle [Aristotle]
9. Objects / C. Structure of Objects / 2. Hylomorphism / d. Form as unifier
Things are a unity because there is no clash between potential matter and actual shape/form [Aristotle]
Aristotle's solution to the problem of unity is that form is an active cause or potentiality or nature [Aristotle, by Gill,ML]
9. Objects / C. Structure of Objects / 3. Matter of an Object
Every distinct thing has matter, as long as it isn't an essence or a Form [Aristotle]
In Aristotle, bronze only becomes 'matter' when it is potentially a statue [Aristotle, by Gill,ML]
Aristotle's conception of matter applies to non-physical objects as well as physical objects [Aristotle, by Fine,K]
Aristotle's matter is something that could be the inner origin of a natural being's behaviour [Aristotle, by Witt]
Matter is secondary, because it is potential, determined by the actuality of form [Aristotle, by Witt]
9. Objects / C. Structure of Objects / 5. Composition of an Object
Is there a house over and above its bricks? [Aristotle]
9. Objects / C. Structure of Objects / 7. Substratum
It is unclear whether Aristotle believes in a propertyless subject, his 'ultimate matter' [Aristotle, by Lawson-Tancred]
A substrate is either a 'this' supporting qualities, or 'matter' supporting actuality [Aristotle]
A subject can't be nothing, so it must qualify as separate, and as having a distinct identity [Aristotle, by Gill,ML]
Something must pre-exist any new production [Aristotle]
If you extract all features of the object, what is left over? [Aristotle]
9. Objects / C. Structure of Objects / 8. Parts of Objects / a. Parts of objects
The contents of an explanatory formula are parts of the whole [Aristotle]
9. Objects / C. Structure of Objects / 8. Parts of Objects / b. Sums of parts
A 'whole' (rather than a mere 'sum') requires an internal order which distinguishes it [Aristotle]
If a syllable is more than its elements, is the extra bit also an element? [Aristotle]
9. Objects / C. Structure of Objects / 8. Parts of Objects / c. Wholes from parts
A syllable is something different from its component vowels and consonants [Aristotle]
Wholes are continuous, rigid, uniform, similar, same kind, similar matter [Aristotle, by Simons]
9. Objects / D. Essence of Objects / 1. Essences of Objects
Aristotelian essence underlies behaviour, or underlies definition, or is the source of existence [Aristotle, by Aquinas]
Aristotelian essence is retained with identity through change, and bases our scientific knowledge [Aristotle, by Copi]
Aristotle says changing, material things (and not just universals) have an essence [Aristotle, by Politis]
Are essences actually universals? [Aristotle, by Politis]
9. Objects / D. Essence of Objects / 2. Types of Essence
Aristotelian essences are causal, not classificatory [Aristotle, by Witt]
9. Objects / D. Essence of Objects / 3. Individual Essences
The essence of a single thing is the essence of a particular [Aristotle]
Particulars are not definable, because they fluctuate [Aristotle]
Essence is the cause of individual substance, and creates its unity [Aristotle, by Witt]
Individual essences are not universals, since those can't be substances, or cause them [Aristotle, by Witt]
Aristotelian essence is not universal properties, but individual essence [Aristotle, by Witt]
Aristotle does not accept individual essences; essential properties are always general [Aristotle, by Kung]
Aristotle's essence explains the existence of an individual substance, not its properties [Aristotle, by Witt]
Aristotle takes essence and form as a particular, not (as some claim) as a universal, the species [Aristotle, by Politis]
To be a subject a thing must be specifiable, with some essential properties [Aristotle, by Gill,ML]
9. Objects / D. Essence of Objects / 4. Essence as Definition
If definition is of universals, many individuals have no definition, and hence no essence [Aristotle, by Witt]
Things have an essence if their explanation is a definition [Aristotle]
A thing's essence is what is mentioned in its definition [Aristotle, by Lawson-Tancred]
Essence is what is stated in the definition [Aristotle, by Politis]
9. Objects / D. Essence of Objects / 5. Essence as Kind
The Aristotelian view is that the essential properties are those that sort an object [Aristotle, by Marcus (Barcan)]
9. Objects / D. Essence of Objects / 6. Essence as Unifier
A thing's essence is its intrinsic nature [Aristotle]
An essence causes both its own unity and its kind [Aristotle]
Having an essence is the criterion of being a substance [Aristotle, by Lawson-Tancred]
9. Objects / D. Essence of Objects / 7. Essence and Necessity / c. Essentials are necessary
Aristotle doesn't see essential truths or essential properties as necessary [Aristotle, by Koslicki]
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
Metaphysics is the science of ultimate explanation, or of pure existence, or of primary existence [Aristotle, by Politis]
9. Objects / D. Essence of Objects / 9. Essence and Properties
It is absurd that a this and a substance should be composed of a quality [Aristotle]
9. Objects / D. Essence of Objects / 10. Essence as Species
Generalities like man and horse are not substances, but universal composites of account and matter [Aristotle]
Genera are not substances, and do not exist apart from the ingredient species [Aristotle]
'Categories' answers 'what?' with species, genus, differerentia; 'Met.' Z.17 seeks causal essence [Aristotle, by Wedin]
Standardly, Aristotelian essences are taken to be universals of the species [Aristotle, by Witt]
In 'Met.' he says genera can't be substances or qualities, so aren't in the ontology [Aristotle, by Frede,M]
9. Objects / D. Essence of Objects / 11. Essence of Artefacts
Things are more unified if the unity comes from their own nature, not from external force [Aristotle]
The hallmark of an artefact is that its active source of maintenance is external [Aristotle, by Gill,ML]
9. Objects / D. Essence of Objects / 14. Knowledge of Essences
Aristotle claims that the individual is epistemologically prior to the universal [Aristotle, by Witt]
Actual knowledge is of the individual, and potential knowledge of the universal [Aristotle, by Witt]
9. Objects / E. Objects over Time / 1. Objects over Time
An a priori principle of persistence anticipates all experience [Kant]
9. Objects / E. Objects over Time / 2. Objects that Change
For animate things, only the form, not the matter or properties, must persist through change [Aristotle, by Frede,M]
9. Objects / E. Objects over Time / 12. Origin as Essential
How a thing is generated does not explain its essence [Aristotle, by Politis]
Aristotle wants definition, not identity, so origin is not essential to him [Aristotle, by Witt]
9. Objects / F. Identity among Objects / 1. Concept of Identity
Two things with the same primary being and essence are one thing [Aristotle]
9. Objects / F. Identity among Objects / 4. Type Identity
Things such as two different quadrangles are alike but not wholly the same [Aristotle]

We can't understand self-identity without a prior grasp of the object [Aristotle]
You are one with yourself in form and matter [Aristotle]
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
The Identity of Indiscernibles is true of concepts with identical properties, but not of particulars [Kant, by Jolley]
If we ignore differences between water drops, we still distinguish them by their location [Kant]
10. Modality / A. Necessity / 1. Types of Modality
Modalities do not augment our concepts; they express their relation to cognition [Kant]
10. Modality / A. Necessity / 2. Nature of Necessity
Necessity makes alternatives impossible [Aristotle]
10. Modality / A. Necessity / 6. Logical Necessity
A thing has a feature necessarily if its denial brings a contradiction [Aristotle]
10. Modality / A. Necessity / 7. Natural Necessity
Natural necessity is the unconditioned necessity of appearances [Kant]
10. Modality / B. Possibility / 1. Possibility
Possibility is when the necessity of the contrary is false [Aristotle]
A concept is logically possible if non-contradictory (but may not be actually possible) [Kant]
Anything which is possible either exists or will come into existence [Aristotle]
Is the possible greater than the actual, and the actual greater than the necessary? [Kant]
The analytic mark of possibility is that it does not generate a contradiction [Kant]
10. Modality / B. Possibility / 4. Potentiality
Potentialities are always for action, but are conditional on circumstances [Aristotle]
We recognise potentiality from actuality [Aristotle]
Things are destroyed not by their powers, but by their lack of them [Aristotle]
A 'potentiality' is a principle of change or process in a thing [Aristotle]
10. Modality / C. Sources of Modality / 4. Necessity from Concepts
Formal experience conditions show what is possible, and general conditions what is necessary [Kant]
10. Modality / C. Sources of Modality / 6. Necessity from Essence
Some things have external causes of their necessity; others (the simple) generate necessities [Aristotle]
Aristotle's says necessary truths are distinct and derive from essential truths [Aristotle, by Koslicki]
10. Modality / D. Knowledge of Modality / 1. A Priori Necessary
Kant thought worldly necessities are revealed by what maths needs to make sense [Kant, by Morris,M]
Necessity is always knowable a priori, and what is known a priori is always necessary [Kant, by Schroeter]
For Kant metaphysics must be necessary, so a priori, so can't be justified by experience [Kant, by Maudlin]
Maths must be a priori because it is necessary, and that cannot be derived from experience [Kant]
11. Knowledge Aims / A. Knowledge / 1. Knowledge
The ability to teach is a mark of true knowledge [Aristotle]
Knowledge is threefold: apprehension, reproduction by imagination, recognition by concepts [Kant, by Bowie]
Knowledge begins with intuitions, moves to concepts, and ends with ideas [Kant]
11. Knowledge Aims / A. Knowledge / 2. Understanding
Kant showed that the understanding (unlike reason) concerns what is finite and conditioned [Kant, by Hegel]
Understanding essentially involves singular elements [Kant, by Burge]
Reason is distinct from understanding, and is the faculty of rules or principles [Kant]
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
Opinion is subjectively and objectively insufficient; belief is subjective but not objective; knowledge is both [Kant]
11. Knowledge Aims / A. Knowledge / 6. Knowing How
Things are produced from skill if the form of them is in the mind [Aristotle]
Experience knows particulars, but only skill knows universals [Aristotle]
It takes skill to know causes, not experience [Aristotle]
11. Knowledge Aims / B. Certain Knowledge / 5. Cogito Critique
'I think therefore I am' is an identity, not an inference (as there is no major premise) [Kant]
11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
There are possible inhabitants of the moon, but they are just possible experiences [Kant]
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / a. Idealism
We have no sensual experience of time and space, so they must be 'ideal' [Kant, by Pinkard]
Objects having to be experiencable is not the same as full idealism [Gardner on Kant]
If we disappeared, then all relations of objects, and time and space themselves, disappear too [Kant]
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / b. Transcendental idealism
In Kantian idealism, objects fit understanding, not vice versa [Kant, by Feuerbach]
Kant's idealism is a limited idealism based on the viewpoint of empiricism [Kant, by Feuerbach]
For Kant experience is either structured like reality, or generates reality's structure [Kant, by Gardner]
The concepts that make judgeable experiences possible are created spontaneously [Kant, by Pinkard]
'Transcendental' cognition concerns what can be known a priori of its mode [Kant]
We cannot know things in themselves, but are confined to appearances [Kant]
We have proved that bodies are appearances of the outer senses, not things in themselves [Kant]
Everything we intuit is merely a representation, with no external existence (Transcendental Idealism) [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 1. Nature of the A Priori
Kant's shift of view enables us to see a priority in terms of mental capacity, not truth and propositions [Burge on Kant]
A priori knowledge is limited to objects of possible experience [Kant, by Jolley]
A priori knowledge occurs absolutely independently of all experience [Kant]
One sort of a priori knowledge just analyses given concepts, but another ventures further [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 2. Self-Evidence
Experienceless bodies have space; propertyless bodies have substance; this must be seen a priori [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 4. A Priori as Necessities
Two plus two objects make four objects even if experience is impossible, so Kant is wrong [Russell on Kant]
Propositions involving necessity are a priori, and pure a priori if they only derive from other necessities [Kant]
The apriori is independent of its sources, and marked by necessity and generality [Kant, by Burge]
A priori knowledge is indispensable for the possibility and certainty of experience [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 5. A Priori Synthetic
Seeing that only one parallel can be drawn to a line through a given point is clearly synthetic a priori [Kant, by Benardete,JA]
Kant bases the synthetic a priori on the categories of oneness and manyness [Kant, by Bowie]
Kant showed that we have a priori knowledge which is not purely analytic [Kant, by Russell]
We can think of 7 and 5 without 12, but it is still a contradiction to deny 7+5=12 [Ayer on Kant]
That a straight line is the shortest is synthetic, as straight does not imply any quantity [Kant]
That force and counter-force are equal is necessary, and a priori synthetic [Kant]
The real problem of pure reason is: how are a priori synthetic judgments possible? [Kant]
That two lines cannot enclose a space is an intuitive a priori synthetic proposition [Kant]
Are a priori concepts necessary as a precondition for something to be an object? [Kant]
7+5=12 is not analytic, because 12 is not contained in 7 or 5 or their combination [Kant]
We possess synthetic a priori knowledge in our principles which anticipate experience [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 6. A Priori from Reason
Reason contains within itself certain underived concepts and principles [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 7. A Priori from Convention
If, as Kant says, arithmetic and logic are contributed by us, they could change if we did [Russell on Kant]
12. Knowledge Sources / A. A Priori Knowledge / 8. A Priori as Analytic
No analysis of the sum of seven and five will in itself reveal twelve [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 9. A Priori from Concepts
For Kant analytic knowledge needs complex concepts, but the a priori can rest on the simple [Coffa on Kant]
With large numbers it is obvious that we could never find the sum by analysing the concepts [Kant]
12. Knowledge Sources / A. A Priori Knowledge / 10. A Priori as Subjective
A priori the understanding can only anticipate possible experiences [Kant]

I exist just as an intelligence aware of its faculty for combination [Kant]
Associations and causes cannot explain content, which needs norms of judgement [Kant, by Pinkard]
12. Knowledge Sources / D. Empiricism / 4. Pro-Empiricism
For Kant, our conceptual scheme is disastrous when it reaches beyond experience [Kant, by Fogelin]
All men long to understand, as shown by their delight in the senses [Aristotle]
12. Knowledge Sources / D. Empiricism / 5. Empiricism Critique
Understanding has no intuitions, and senses no thought, so knowledge needs their unity [Kant]
Sensations are a posteriori, but that they come in degrees is known a priori [Kant]
12. Knowledge Sources / E. Direct Knowledge / 2. Intuition
Kantian intuitions are of particulars, and they give immediate knowledge [Kant, by Shapiro]
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / e. Pro-foundations

Scepticism is the euthanasia of pure reason [Kant]
Scepticism is absurd in maths, where there are no hidden false assertions [Kant]

For Kant, experience is relative to a scheme, but there are no further possible schemes [Kant, by Fogelin]
13. Knowledge Criteria / E. Relativism / 3. Subjectivism
If truth is relative it is relational, and concerns appearances relative to a situation [Aristotle]
If relativism is individual, how can something look sweet and not taste it, or look different to our two eyes? [Aristotle]
13. Knowledge Criteria / E. Relativism / 6. Relativism Critique
If the majority had diseased taste, and only a few were healthy, relativists would have to prefer the former [Aristotle]

15. Nature of Minds / C. Capacities of Minds / 1. Faculties
Kant's only answer as to how synthetic a priori judgements are possible was that we have a 'faculty'! [Nietzsche on Kant]
Reason has logical and transcendental faculties [Kant]

Kant deduced the categories from our judgements, and then as preconditions of experience [Kant, by Houlgate]
Kant says we can describe the categories of thought, but Hegel claims to deduce them [Kant, by Meillassoux]
Categories are concepts that prescribe laws a priori to appearances [Kant]

26. Natural Theory / C. Causation / 9. General Causation / b. Nomological causation
Pure Forms and numbers can't cause anything, and especially not movement [Aristotle]
The concept of causality entails laws; random causality is a contradiction [Kant, by Korsgaard]
We judge causation by relating events together by some law of nature [Kant, by Mares]
Experience is only possible because we subject appearances to causal laws [Kant]
26. Natural Theory / C. Causation / 9. General Causation / d. Causal necessity
When a power and its object meet in the right conditions, an action necessarily follows [Aristotle]
Causation obviously involves necessity, so it cannot just be frequent association [Kant]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / b. Scientific necessity
For Kant the laws must be necessary, because contingency would destroy representation [Kant, by Meillassoux]
Kant fails to prove the necessity of laws, because his reasoning about chance is over-ambitious [Meillassoux on Kant]
27. Natural Reality / C. Space / 2. Space
We can't learn of space through experience; experience of space needs its representation [Kant]
Space is an a priori necessary basic intuition, as we cannot imagine its absence [Kant]
27. Natural Reality / D. Time / 1. Nature of Time / a. Absolute time
If space and time exist absolutely, we must assume the existence of two pointless non-entities [Kant]
27. Natural Reality / D. Time / 1. Nature of Time / c. Idealist time
One can never imagine appearances without time, so it is given a priori [Kant]
27. Natural Reality / D. Time / 2. Passage of Time / a. Experience of time
That times cannot be simultaneous is synthetic, so it is known by intuition, not analysis [Kant]
The three modes of time are persistence, succession and simultaneity [Kant]
27. Natural Reality / D. Time / 2. Passage of Time / b. Rate of time
If time involved succession, we must think of another time in which succession occurs [Kant]
27. Natural Reality / D. Time / 3. Parts of Time / a. Beginning of time
It is hard to see how either time or movement could come into existence or be destroyed [Aristotle]
27. Natural Reality / E. Cosmology / 3. The Beginning
The first mover is necessary, and because it is necessary it is good [Aristotle]
Something which both moves and is moved is intermediate, so it follows that there must be an unmoved mover [Aristotle]
Even if the world is caused by fate, mind and nature are still prior causes [Aristotle]
28. God / A. Divine Nature / 2. Divine Nature
There must a source of movement which is eternal, indivisible and without magnitude [Aristotle]
28. God / A. Divine Nature / 5. God and Time
God is not a creator (involving time and change) and is not concerned with the inferior universe [Aristotle, by Armstrong,K]
28. God / A. Divine Nature / 6. Divine Morality / b. Euthyphro question
We don't accept duties as coming from God, but assume they are divine because they are duties [Kant]
28. God / B. Proving God / 1. Proof of God
For Aristotle God is defined in an axiom, for which there is no proof [Aristotle, by Frede,M]
Only three proofs of God: the physico-theological (evidence), the cosmological (existence), the ontological (a priori) [Kant]
28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique
If 'this exists' is analytic, either the thing is a thought, or you have presupposed its existence [Kant]
If an existential proposition is synthetic, you must be able to cancel its predicate without contradiction [Kant]
Being is not a real predicate, that adds something to a concept [Kant]
You add nothing to the concept of God or coins if you say they exist [Kant]
Existence is merely derived from the word 'is' (rather than being a predicate) [Kant, by Orenstein]
Modern logic says (with Kant) that existence is not a predicate, because it has been reclassified as a quantifier [Benardete,JA on Kant]
Kant never denied that 'exist' could be a predicate - only that it didn't enlarge concepts [Kant, by Fitting/Mendelsohn]
Is "This thing exists" analytic or synthetic? [Kant]
28. God / B. Proving God / 3. Proofs of Evidence / a. Cosmological Proof
If you prove God cosmologically, by a regress in the sequences of causes, you can't abandon causes at the end [Kant]
28. God / B. Proving God / 3. Proofs of Evidence / b. Teleological Proof
The world can't be arranged at all if there is nothing eternal and separate [Aristotle]
29. Religion / A. Polytheistic Religion / 2. Greek Polytheism
There are as many eternal unmovable substances as there are movements of the stars [Aristotle]
