| 12558 | Truth only belongs to mental or verbal propositions [Locke] |
| 12522 | It is propositions which are true or false, though it is sometimes said of ideas [Locke] |

| 7782 | Every simple idea we ever have brings the idea of unity along with it [Locke] |
| 324 | Before the existence of the world there must have been being, space and becoming [Plato] |
| 20364 | The apprehensions of reason remain unchanging, but reasonless sensation shows mere becoming [Plato] |

| 12517 | Ideas are uncertain when they are unnamed, because too close to other ideas [Locke] |
| 13435 | We can't categorise things by their real essences, because these are unknown [Locke] |

| 13436 | There are no gaps in the continuum of nature, and everything has something closely resembling it [Locke] |
| 12490 | Power is active or passive, and has a relation to actions [Locke] |

| 12521 | We can only know a thing's powers when we have combined it with many things [Locke] |
| 15974 | The essence of whiteness in a man is nothing but the power to produce the idea of whiteness [Locke] |
| 15976 | What is the texture - the real essence - which makes substances behave in distinct ways? [Locke] |

| 12042 | Plato's Forms were seen as part of physics, rather than of metaphysics [Plato, by Annas] |
| 307 | Something will always be well-made if the maker keeps in mind the eternal underlying pattern [Plato] |
| 318 | In addition to the underlying unchanging model and a changing copy of it, there must also be a foundation of all change [Plato] |
| 321 | For knowledge and true opinion to be different there must be Forms; otherwise we are just stuck with sensations [Plato] |
| 317 | The universe is basically an intelligible and unchanging model, and a visible and changing copy of it [Plato] |
| 7717 | All things that exist are particulars [Locke] |
| 7718 | Universals do not exist, but are useful inventions of the mind, involving words or ideas [Locke] |
| 12499 | Bodies distinctively have cohesion of parts, and power to communicate motion [Locke] |

| 12529 | I speak of a 'sortal' name, from the word 'sort' [Locke] |
| 8546 | Powers are part of our idea of substances [Locke] |
| 1196 | We can conceive of three sorts of substance: God, finite intelligence, and bodies [Locke] |
| 12536 | We sort and name substances by nominal and not by real essence [Locke] |
| 7945 | We think of substance as experienced qualities plus a presumed substratum of support [Locke] |
| 12485 | We don't know what substance is, and only vaguely know what it does [Locke] |
| 16796 | Locke may accept coinciding material substances, such as body, man and person [Locke, by Pasnau] |
| 12507 | A mass consists of its atoms, so the addition or removal of one changes its identity [Locke] |
| 12559 | Complex ideas are collections of qualities we attach to an unknown substratum [Locke] |
| 12498 | Particular substances are coexisting ideas that seem to flow from a hidden essence [Locke] |
| 12520 | The best I can make of real essence is figure, size and connection of solid parts [Locke] |
| 13771 | Real essence is the constitution of the unknown parts of a body which produce its qualities [Locke] |
| 16038 | Locke may distinguish real essence from internal constitution, claiming the latter is knowable [Locke, by Jones,J-E] |
| 12810 | We can conceive an individual without assigning it to a kind [Locke, by Jolley] |
| 16786 | You can't distinguish individuals without the species as a standard [Locke] |
| 15992 | Many individuals grouped under one name vary more than some things that have different names [Locke] |
| 12530 | The less rational view of essences is that they are moulds for kinds of natural thing [Locke] |
| 12532 | Even real essence depends on a sort, since it is sorts which have the properties [Locke] |
| 12539 | If every sort has its real essence, one horse, being many sorts, will have many essences [Locke] |
| 11155 | Essence is the very being of any thing, whereby it is what it is [Locke] |
| 12510 | Not all identity is unity of substance [Locke] |
| 12560 | We can only slightly know necessary co-existence of qualities, if they are primary [Locke] |
| 16787 | Explanatory essence won't do, because it won't distinguish the accidental from the essential [Locke, by Pasnau] |
| 16028 | Lockean real essence makes a thing what it is, and produces its observable qualities [Locke, by Jones,J-E] |
| 12305 | Locke's essences determine the other properties, so the two will change together [Locke, by Copi] |
| 15985 | It is impossible for two things with the same real essence to differ in properties [Locke] |
| 12534 | We cannot know what properties are necessary to gold, unless we first know its real essence [Locke] |
| 13434 | In our ideas, the idea of essence is inseparable from the concept of a species [Locke] |
| 16035 | If we based species on real essences, the individuals would be as indistinguishable as two circles [Locke] |
| 16036 | Internal constitution doesn't decide a species; should a watch contain four wheels or five? [Locke] |
| 12540 | Artificial things like watches and pistols have distinct kinds [Locke] |
| 16031 | Real essence explains observable qualities, but not what kind of thing it is [Locke, by Jones,J-E] |
| 15646 | If essence is 'nominal', artificial gold (with its surface features) would qualify as 'gold' [Locke, by Eagle] |
| 12306 | 'Nominal essence' is everything contained in the idea of a particular sort of thing [Locke, by Copi] |
| 15988 | The observable qualities are never the real essence, since they depend on real essence [Locke] |
| 12537 | To be a nominal essence, a complex idea must exhibit unity [Locke] |
| 15644 | In nominal essence, Locke confuses the set of properties with the abstracted idea of them [Eagle on Locke] |
| 16029 | Locke's real and nominal essence refers back to Aristotle's real and nominal definitions [Locke, by Jones,J-E] |
| 12531 | Nominal Essence is the abstract idea to which a name is attached [Locke] |
| 13433 | Essences relate to sorting words; if you replace those with names, essences vanish [Locke] |
| 12533 | Real essences are unknown, so only the nominal essence connects things to a species [Locke] |
| 12557 | Our ideas of substance are based on mental archetypes, but these come from the world [Locke] |
| 12561 | For 'all gold is malleable' to be necessary, it must be part of gold's nominal essence [Locke] |
| 12525 | The essence of a triangle is simple; presumably substance essences are similar [Locke] |
| 13431 | A space between three lines is both the nominal and real essence of a triangle, the source of its properties [Locke] |
| 13423 | The schools recognised that they don't really know essences, because they couldn't coin names for them [Locke] |
| 12804 | There are no independent natural kinds - or our classifications have to be subjective [Locke, by Jolley] |
| 12547 | We know five properties of gold, but cannot use four of them to predict the fifth one [Locke] |
| 12503 | Identity means that the idea of a thing remains the same over time [Locke] |
| 12505 | One thing cannot have two beginnings of existence, nor two things one beginning [Locke] |
| 16795 | Same person, man or substance are different identities, belonging to different ideas [Locke] |
| 12504 | Two things can't occupy one place and time, which leads us to the idea of self-identity [Locke] |
| 12553 | Some of our ideas contain relations which we cannot conceive to be absent [Locke] |
| 12544 | Our knowledge falls short of the extent of our own ideas [Locke] |
| 12574 | When two ideas agree in my mind, I cannot refuse to see and know it [Locke] |
| 15995 | The greatest certainty is knowing our own ideas, and that two ideas are different [Locke] |
| 12562 | General certainty is only found in ideas [Locke] |
| 12569 | Knowledge by senses is less certain than that by intuition or reason, but it is still knowledge [Locke] |
| 12564 | I am as certain of the thing doubting, as I am of the doubt [Locke] |
| 7570 | Innate ideas are trivial (if they are just potentials) or absurd (if they claim infants know a lot) [Locke, by Jolley] |
| 12472 | If the only test of innateness is knowing, then all of our knowledge is innate [Locke] |
| 7709 | A proposition can't be in the mind if we aren't conscious of it [Locke] |
| 4018 | Innate ideas were followed up with innate doctrines, which stopped reasoning and made social control possible [Locke] |
| 7723 | The senses first let in particular ideas, which furnish the empty cabinet [Locke] |
| 7507 | The mind is white paper, with no writing, or ideas [Locke] |
| 12474 | The mind is a blank page, on which only experience can write [Locke] |
| 12518 | The mind cannot produce simple ideas [Locke] |
| 12478 | A 'quality' is a power to produce an idea in our minds [Locke] |
| 15989 | Colours, smells and tastes are ideas; the secondary qualities have no colour, smell or taste [Locke, by Alexander,P] |
| 15971 | Secondary qualities are powers of complex primary qualities to produce sensations in us [Locke] |
| 12481 | Hands can report conflicting temperatures, but not conflicting shapes [Locke] |
| 12546 | We can't know how primary and secondary qualities connect together [Locke] |
| 6725 | Locke believes matter is an inert, senseless substance, with extension, figure and motion [Locke, by Berkeley] |
| 15982 | Qualities are named as primary if they are needed for scientific explanation [Locke, by Alexander,P] |
| 12479 | Primary qualities produce simple ideas, such as solidity, extension, motion and number [Locke] |
| 12480 | Ideas of primary qualities resemble their objects, but those of secondary qualities don't [Locke] |
| 7049 | In Locke, the primary qualities are also powers [Locke, by Heil] |
| 15973 | In my view Locke's 'textures' are groups of corpuscles which are powers (rather than 'having' powers) [Locke, by Alexander,P] |
| 7050 | I suspect that Locke did not actually believe colours are 'in the mind' [Locke, by Heil] |
| 15979 | Secondary qualities are simply the bare powers of an object [Locke] |
| 12482 | Molyneux's Question: could a blind man distinguish cube from sphere, if he regained his sight? [Locke] |
| 334 | Only bird-brained people think astronomy is entirely a matter of evidence [Plato] |
| 7724 | All the ideas written on the white paper of the mind can only come from one place - experience [Locke] |
| 12527 | Some ideas connect together naturally, while others connect by chance or custom [Locke] |
| 12555 | The constant link between whiteness and things that produce it is the basis of our knowledge [Locke] |
| 12542 | Knowledge is just the connection or disagreement of our ideas [Locke] |
| 16637 | The absolute boundaries of our thought are the ideas we get from senses and the mind [Locke] |
| 2793 | It is unclear how identity, equality, perfection, God, power and cause derive from experience [Locke, by Dancy,J] |
| 12543 | Intuition gives us direct and certain knowledge of what is obvious [Locke] |
| 19517 | Believing without a reason may just be love of your own fantasies [Locke] |
| 15977 | Facts beyond immediate experience are assessed by agreement with known truths and observations [Locke] |
| 2555 | For Locke knowledge relates to objects, not to propositions [Locke, by Rorty] |
| 10326 | Other men's opinions don't add to our knowledge - even when they are true [Locke] |
| 6488 | Locke has no patience with scepticism [Locke, by Robinson,H] |
| 16037 | Locke seems to use real essence for scientific explanation, and substratum for the being of a thing [Locke, by Jones,J-E] |
| 16032 | To explain qualities, Locke invokes primary and secondary qualities, not real essences [Locke, by Jones,J-E] |
| 12519 | Gold is supposed to have a real essence, from whence its detectable properties flow [Locke] |
| 5962 | Plato says the soul is ordered by number [Plato, by Plutarch] |
| 12551 | We are satisfied that other men have minds, from their words and actions [Locke] |
| 12483 | Unlike humans, animals cannot entertain general ideas [Locke] |
| 5002 | Consciousness is the perception of what passes in a man's own mind [Locke] |
| 2603 | If we aren't aware that an idea is innate, the concept of innate is meaningless; if we do, all ideas seem innate [Locke] |
| 2421 | There is nothing illogical about inverted qualia [Locke] |
| 3522 | The same object might produce violet in one mind and marigold in another [Locke] |
| 7721 | Locke's view that thoughts are made of ideas asserts the crucial role of imagination [Locke] |
| 12476 | Every external object or internal idea suggests to us the idea of unity [Locke] |
| 12501 | The mind can make a unity out of anything, no matter how diverse [Locke] |
| 9083 | The mind creates abstractions by generalising about appearances of objects, ignoring time or place [Locke] |
| 7040 | General words represent general ideas, which are abstractions from immediate circumstances [Locke] |
| 12528 | If a man sees a friend die in a room, he associates the pain with the room [Locke] |

| 1373 | Identity over time involves remembering actions just as they happened [Locke] |
| 1380 | Should we punish people who commit crimes in their sleep? [Locke] |
| 5511 | For Locke, conscious awareness unifies a person at an instant and over time [Locke, by Martin/Barresi] |
| 12509 | If the soul individuates a man, and souls are transferable, then a hog could be a man [Locke] |
| 1376 | Identity must be in consciousness not substance, because it seems transferable [Locke] |
| 12512 | If someone becomes conscious of Nestor's actions, then he is Nestor [Locke] |
| 12513 | If a prince's soul entered a cobbler's body, the person would be the prince (and the man the cobbler) [Locke] |
| 12514 | On Judgement Day, no one will be punished for actions they cannot remember [Locke] |
| 1397 | Locke sees underlying substance as irrelevant to personal identity [Locke, by Noonan] |
| 6139 | Locke implies that each thought has two thinkers - me, and 'my' substance [Merricks on Locke] |
| 5513 | Two persons might have qualitatively identical consciousnesses, so that isn't enough [Kant on Locke] |
| 1345 | Locke's move from substance to consciousness is a slippery slope [Butler on Locke] |
| 1197 | No two thoughts at different times can be the same, as they have different beginnings [Locke] |
| 1364 | Locke confuses the test for personal identity with the thing itself [Reid on Locke] |
| 12511 | If consciousness is interrupted, and we forget our past selves, are we still the same thinking thing? [Locke] |

| 12809 | Nothing about me is essential [Locke] |
| 3792 | We are free to decide not to follow our desires [Locke] |
| 12494 | Men are not free to will, because they cannot help willing [Locke] |

| 12500 | Thinking without matter and matter that thinks are equally baffling [Locke] |
| 15996 | We can't begin to conceive what would produce some particular experience within our minds [Locke] |
| 12552 | Thoughts moving bodies, and bodies producing thoughts, are equally unknowable [Locke] |

| 6486 | Ideas are the objects of understanding when we think [Locke] |
| 12496 | Complex ideas are all resolvable into simple ideas [Locke] |
| 12475 | All our ideas derive either from sensation, or from inner reflection [Locke] |
| 17735 | Simple ideas are produced in us by external things, and they match their appearances [Locke] |
| 12471 | Innate ideas are nothing, if they are in the mind but we are unaware of them [Locke] |
| 5827 | A species of thing is an abstract idea, and a word is a sign that refers to the idea [Locke] |
| 7716 | Words were devised as signs for inner ideas, and their basic meaning is those ideas [Locke] |
| 7308 | Words stand for the ideas in the mind of him that uses them [Locke] |
| 12524 | For the correct reference of complex ideas, we can only refer to experts [Locke] |

| 331 | Bad governments prevent discussion, and discourage the study of virtue [Plato] |
| 310 | The creator of the cosmos had no envy, and so wanted things to be as like himself as possible [Plato] |
| 311 | The cosmos must be unique, because it resembles the creator, who is unique [Plato] |
| 15997 | We are so far from understanding the workings of natural bodies that it is pointless to even try [Locke] |
| 325 | We must consider the four basic shapes as too small to see, only becoming visible in large numbers [Plato] |
| 15978 | I take 'matter' to be a body, excluding its extension in space and its shape [Locke] |
| 15170 | We distinguish species by their nominal essence, not by their real essence [Locke] |
| 15993 | If we observe total regularity, there must be some unknown law and relationships controlling it [Locke] |

| 12550 | If we knew the minute mechanics of hemlock, we could predict that it kills men [Locke] |
| 15966 | Boyle and Locke believed corpuscular structures necessitate their powers of interaction [Locke, by Alexander,P] |
| 15984 | The corpuscular hypothesis is the best explanation of the necessary connection and co-existence of powers [Locke] |

| 12565 | God has given us no innate idea of himself [Locke] |
| 21241 | Even the fool can hold 'a being than which none greater exists' in his understanding [Anselm] |
| 21243 | An existing thing is even greater if its non-existence is inconceivable [Anselm] |
| 21244 | Conceiving a greater being than God leads to absurdity [Anselm] |
| 21242 | If that than which a greater cannot be thought actually exists, that is greater than the mere idea [Anselm] |
| 1421 | A perfection must be independent and unlimited, and the necessary existence of Anselm's second proof gives this [Malcolm on Anselm] |
| 21245 | The word 'God' can be denied, but understanding shows God must exist [Anselm] |

| 21247 | Nonexistence is impossible for the greatest thinkable thing, which has no beginning or end [Anselm] |
| 1420 | Anselm's first proof fails because existence isn't a real predicate, so it can't be a perfection [Malcolm on Anselm] |
| 12566 | We exist, so there is Being, which requires eternal being [Locke] |
| 12571 | If miracles aim at producing belief, it is plausible that their events are very unusual [Locke] |
