| 11244 | Metaphysics is the science of ultimate explanation, or of pure existence, or of primary existence [Aristotle, by Politis] |
| 16143 | It is absurd that a this and a substance should be composed of a quality [Aristotle] |
| 16106 | Generalities like man and horse are not substances, but universal composites of account and matter [Aristotle] |
| 16144 | Genera are not substances, and do not exist apart from the ingredient species [Aristotle] |
| 12359 | 'Categories' answers 'what?' with species, genus, differerentia; 'Met.' Z.17 seeks causal essence [Aristotle, by Wedin] |
| 12068 | Standardly, Aristotelian essences are taken to be universals of the species [Aristotle, by Witt] |
| 16141 | In 'Met.' he says genera can't be substances or qualities, so aren't in the ontology [Aristotle, by Frede,M] |
| 16508 | Things are more unified if the unity comes from their own nature, not from external force [Aristotle] |
| 16117 | The hallmark of an artefact is that its active source of maintenance is external [Aristotle, by Gill,ML] |
| 12092 | Aristotle claims that the individual is epistemologically prior to the universal [Aristotle, by Witt] |
| 12090 | Actual knowledge is of the individual, and potential knowledge of the universal [Aristotle, by Witt] |
| 16173 | Coming to be is by shape-change, addition, subtraction, composition or alteration [Aristotle] |
| 17042 | Natural things are their own source of stability through change [Aristotle] |
| 16159 | For animate things, only the form, not the matter or properties, must persist through change [Aristotle, by Frede,M] |
| 16691 | A day, or the games, has one thing after another, actually and potentially occurring [Aristotle] |
| 16574 | Coming-to-be may be from nothing in a qualified way, as arising from an absence [Aristotle] |
| 11378 | How a thing is generated does not explain its essence [Aristotle, by Politis] |
| 12101 | Aristotle wants definition, not identity, so origin is not essential to him [Aristotle, by Witt] |
| 11380 | Two things with the same primary being and essence are one thing [Aristotle] |
| 17848 | Things such as two different quadrangles are alike but not wholly the same [Aristotle] |
| 16134 | We can't understand self-identity without a prior grasp of the object [Aristotle] |
| 17847 | You are one with yourself in form and matter [Aristotle] |
| 12611 | Necessity makes alternatives impossible [Aristotle] |
| 17852 | A thing has a feature necessarily if its denial brings a contradiction [Aristotle] |
| 15779 | Possibility is when the necessity of the contrary is false [Aristotle] |
| 15769 | Anything which is possible either exists or will come into existence [Aristotle] |
| 15774 | We recognise potentiality from actuality [Aristotle] |
| 11254 | Matter is potentiality [Aristotle, by Politis] |
| 14544 | Potentialities are always for action, but are conditional on circumstances [Aristotle] |
| 15777 | A 'potentiality' is a principle of change or process in a thing [Aristotle] |
| 15778 | Things are destroyed not by their powers, but by their lack of them [Aristotle] |
| 13108 | Chance is a coincidental cause among events involving purpose and choice [Aristotle] |
| 13110 | Intrinsic cause is prior to coincidence, so nature and intelligence are primary causes, chance secondary [Aristotle] |
| 13106 | Maybe there is no pure chance; a man's choices cause his chance meetings [Aristotle] |
| 12612 | Some things have external causes of their necessity; others (the simple) generate necessities [Aristotle] |
| 15108 | Aristotle's says necessary truths are distinct and derive from essential truths [Aristotle, by Koslicki] |
| 547 | The ability to teach is a mark of true knowledge [Aristotle] |
| 544 | Experience knows particulars, but only skill knows universals [Aristotle] |
| 10950 | Things are produced from skill if the form of them is in the mind [Aristotle] |
| 546 | It takes skill to know causes, not experience [Aristotle] |
| 543 | All men long to understand, as shown by their delight in the senses [Aristotle] |
| 8331 | To know something we need understanding, which is grasp of the primary cause [Aristotle] |
| 583 | The starting point of a proof is not a proof [Aristotle] |
| 581 | Dreams aren't a serious problem. No one starts walking round Athens next morning, having dreamt that they were there! [Aristotle] |
| 585 | If relativism is individual, how can something look sweet and not taste it, or look different to our two eyes? [Aristotle] |
| 584 | If truth is relative it is relational, and concerns appearances relative to a situation [Aristotle] |
| 576 | If the majority had diseased taste, and only a few were healthy, relativists would have to prefer the former [Aristotle] |
| 12309 | There cannot be a science of accidentals, but only of general truths [Aristotle] |
| 11386 | Demonstrations about particulars must be about everything of that type [Aristotle] |
| 11385 | Universal principles are not primary beings, but particular principles are not universally knowable [Aristotle] |
| 5080 | We know a thing if we grasp its first causes, principles and basic elements [Aristotle] |
| 11289 | Understanding moves from the less to the more intelligible [Aristotle] |
| 16969 | Science refers the question Why? to four causes/explanations: matter, form, source, purpose [Aristotle] |
| 11250 | Four Explanations: the essence and form; the matter; the source; and the end [Aristotle, by Politis] |
| 12045 | Aristotle's four 'causes' are four items which figure in basic explanations of nature [Aristotle, by Annas] |
| 16968 | There are as many causes/explanations as there are different types of why-question [Aristotle] |
| 11246 | Aristotelian explanations mainly divide things into natural kinds [Aristotle, by Politis] |
| 13109 | Chance is inexplicable, because we can only explain what happens always or usually [Aristotle] |
| 16135 | Real enquiries seek causes, and causes are essences [Aristotle] |
| 11384 | We know something when we fully know what it is, not just its quality, quantity or location [Aristotle] |
| 16105 | We know a thing when we grasp its essence [Aristotle] |
| 11296 | The explanation is what gives matter its state, which is the form, which is the substance [Aristotle] |
| 11999 | Essential properties explain in conjunction with properties shared by the same kind [Aristotle, by Kung] |
| 9088 | Skill comes from a general assumption obtained from thinking about similar things [Aristotle] |
| 16153 | Aristotle distinguishes two different sorts of generality - kinds, and properties [Aristotle, by Frede,M] |
| 9791 | Science is more accurate when it is prior and simpler, especially without magnitude or movement [Aristotle] |
| 571 | Is Socrates the same person when standing and when seated? [Aristotle] |
| 23311 | Aristotle sees reason as much more specific than our more everyday concept of it [Aristotle, by Frede,M] |
| 23310 | Animals live by sensations, and some have good memories, but they don't connect experiences [Aristotle] |
| 11245 | Many memories make up a single experience [Aristotle] |
| 10954 | It is unclear whether acute angles are prior to right angles, or fingers to men [Aristotle] |
| 9789 | You can't abstract natural properties to make Forms - objects and attributes are defined together [Aristotle] |
| 9788 | Mathematicians study what is conceptually separable, and doesn't lead to error [Aristotle] |
| 9792 | Mathematicians study quantity and continuity, and remove the perceptible features of things [Aristotle] |
| 9077 | Mathematicians suppose inseparable aspects to be separable, and study them in isolation [Aristotle] |
| 9075 | If health happened to be white, the science of health would not study whiteness [Aristotle] |
| 5107 | Predicates are substance, quality, place, relation, quantity and action or affection [Aristotle] |
| 20042 | We assign the cause of someone's walking when we say why they are doing it [Aristotle] |
| 636 | Beauty involves the Forms of order, symmetry and limit, which can be handled mathematically [Aristotle] |
| 635 | The good is found in actions, but beauty can exist without movement [Aristotle] |
| 15772 | A thing's active function is its end [Aristotle] |
| 629 | Is the good a purpose, a source of movement, or a pure form? [Aristotle] |
| 5110 | Goodness is when a thing (such as a circle) is complete, and conforms with its nature [Aristotle] |
| 5111 | All moral virtue is concerned with bodily pleasure and pain [Aristotle] |
| 591 | Excellence is a sort of completion [Aristotle] |
| 625 | Is excellence separate from things, or part of them, or both? [Aristotle] |
| 621 | Contemplation is a supreme pleasure and excellence [Aristotle] |
| 11241 | Wise men aren't instructed; they instruct [Aristotle] |
| 5092 | Nature is a principle of change, so we must understand change first [Aristotle] |
| 5113 | Nothing natural is disorderly, because nature is responsible for all order [Aristotle] |
| 632 | Why are some things destructible and others not? [Aristotle] |
| 5085 | 'Nature' refers to two things - form and matter [Aristotle] |
| 5089 | Nature has purpose, and aims at what is better. Is it coincidence that crops grow when it rains? [Aristotle] |
| 626 | Everything is arranged around a single purpose [Aristotle] |
| 5086 | The nature of a thing is its end and purpose [Aristotle] |
| 5087 | A thing's purpose is ambiguous, and from one point of view we ourselves are ends [Aristotle] |
| 5091 | Teeth and crops are predictable, so they cannot be mere chance, but must have a purpose [Aristotle] |
| 5108 | Is ceasing-to-be unnatural if it happens by force, and natural otherwise? [Aristotle] |
| 17858 | Pythagoreans say the whole universe is made of numbers [Aristotle] |
| 5095 | The heavens seem to be infinite, because we cannot imagine their end [Aristotle] |
| 5093 | Continuity depends on infinity, because the continuous is infinitely divisible [Aristotle] |
| 601 | Substance must exist, because something must endure during change between opposites [Aristotle] |
| 16762 | Matter desires form, as female desires male, and ugliness desires beauty [Aristotle] |
| 10955 | Matter is perceptible (like bronze) or intelligible (like mathematical objects) [Aristotle] |
| 16590 | Matter is neither a particular thing nor a member of a determinate category [Aristotle] |
| 12001 | Aristotle says matter is a lesser substance, rather than wholly denying that it is a substance [Aristotle, by Kung] |
| 12299 | Aristotle had a hierarchical conception of matter [Aristotle, by Fine,K] |
| 15954 | Aristotle may only have believed in prime matter because his elements were immutable [Aristotle, by Alexander,P] |
| 16099 | The traditional view of Aristotle is God (actual form) at top and prime matter (potential matter) at bottom [Aristotle, by Gill,ML] |
| 15771 | Primary matter is what characterises other stuffs, and it has no distinct identity [Aristotle] |
| 12868 | Ultimate matter is discredited, as Aristotle merged substratum of change with bearer of properties [Simons on Aristotle] |
| 616 | It doesn't explain the world to say it was originally all one. How did it acquire diversity? [Aristotle] |
| 17464 | When Aristotle's elements compound they are stable, so why would they ever separate? [Weisberg/Needham/Hendry on Aristotle] |
| 16098 | I claim that Aristotle's foundation is the four elements, and not wholly potential prime matter [Aristotle, by Gill,ML] |
| 10952 | Unusual kinds like mule are just a combination of two kinds [Aristotle] |
| 11252 | The 'form' of a thing explains why the matter constitutes that particular thing [Aristotle, by Politis] |
| 11253 | A 'material' cause/explanation is the form of whatever is the source [Aristotle, by Politis] |
| 13107 | Causes produce a few things in their own right, and innumerable things coincidentally [Aristotle] |
| 8332 | The four causes are the material, the form, the source, and the end [Aristotle] |
| 561 | Is there cause outside matter, and can it be separated, and is it one or many? [Aristotle] |
| 588 | We exercise to be fit, but need fitness to exercise [Aristotle] |
| 634 | Pure Forms and numbers can't cause anything, and especially not movement [Aristotle] |
| 14543 | When a power and its object meet in the right conditions, an action necessarily follows [Aristotle] |
| 9787 | Scientists must know the essential attributes of the things they study [Aristotle] |
| 20063 | Motion fulfils potentiality [Aristotle] |
| 5114 | If movement can arise within an animal, why can't it also arise in the universe? [Aristotle] |
| 5116 | When there is unnatural movement (e.g. fire going downwards) the cause is obvious [Aristotle] |
| 5099 | The universe as a whole is not anywhere [Aristotle] |
| 5097 | If everything has a place, this causes an infinite regress, because each place must have place [Aristotle] |
| 5098 | Place is not shape, or matter, or extension between limits; it is the limits of a body [Aristotle] |
| 20920 | If there were many cosmoses, each would have its own time, giving many times [Aristotle] |
| 5106 | Would there be time if there were no mind? [Aristotle] |
| 22967 | It is unclear whether time depends on the existence of soul [Aristotle] |
| 8590 | Time does not exist without change [Aristotle] |
| 22965 | Time measures rest, as well as change [Aristotle] |
| 22885 | For Aristotle time is not a process but a means for measuring processes [Aristotle, by Bardon] |
| 22959 | Time is not change, but the number we associate with change [Aristotle] |
| 22964 | Change only exists in time through its being temporally measure [Aristotle] |
| 5104 | Time is an aspect of change [Aristotle] |
| 22956 | How can time exist, when it is composed of what has ceased to be and is yet to be? [Aristotle] |
| 5102 | If all of time has either ceased to exist, or has not yet happened, maybe time does not exist [Aristotle] |
| 5103 | Time is not change, but requires change in our minds to be noticed [Aristotle] |
| 22961 | The present moment is obviously a necessary feature of time [Aristotle] |
| 22916 | Unlike time, change goes at different rates, and is usually localised [Aristotle, by Le Poidevin] |
| 617 | It is hard to see how either time or movement could come into existence or be destroyed [Aristotle] |
| 16693 | Time has parts, but the now is not one of them, and time is not composed of nows [Aristotle] |
| 22958 | Nows can't be linked together, any more than points on a line [Aristotle] |
| 22968 | Circular motion is the most obvious measure of time, and especially the celestial sphere [Aristotle] |
| 22963 | We measure change by time, and time by change, as they are interdefined [Aristotle] |
| 22966 | The present moment is a link (of past to future), and also a limit (of past and of future) [Aristotle] |
| 22957 | We can't tell whether the changing present moment is one thing, or a succession of things [Aristotle] |
| 5083 | Do things come to be from what is, or from what is not? Both seem problematical. [Aristotle] |
| 620 | The first mover is necessary, and because it is necessary it is good [Aristotle] |
| 613 | Even if the world is caused by fate, mind and nature are still prior causes [Aristotle] |
| 619 | Something which both moves and is moved is intermediate, so it follows that there must be an unmoved mover [Aristotle] |
| 5119 | The source of all movement must be indivisible and have no magnitude [Aristotle] |
| 622 | There must a source of movement which is eternal, indivisible and without magnitude [Aristotle] |
| 7603 | God is not a creator (involving time and change) and is not concerned with the inferior universe [Aristotle, by Armstrong,K] |
| 16165 | For Aristotle God is defined in an axiom, for which there is no proof [Aristotle, by Frede,M] |
| 610 | The world can't be arranged at all if there is nothing eternal and separate [Aristotle] |
| 12097 | There are as many eternal unmovable substances as there are movements of the stars [Aristotle] |
