| 16796 | Locke may accept coinciding material substances, such as body, man and person [Locke, by Pasnau] |
| 17043 | Form, not matter, is a thing's nature, because it is actual, rather than potential [Aristotle] |
| 16970 | A thing's form and purpose are often the same, and form can be the initiator of change too [Aristotle] |
| 16104 | Unity of the form is just unity of the definition [Aristotle] |

| 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] |

| 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] |

| 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] |

| 11254 | Matter is potentiality [Aristotle, by Politis] |
| 13110 | Intrinsic cause is prior to coincidence, so nature and intelligence are primary causes, chance secondary [Aristotle] |

| 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] |

| 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] |

| 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] |
| 13109 | Chance is inexplicable, because we can only explain what happens always or usually [Aristotle] |
| 16037 | Locke seems to use real essence for scientific explanation, and substratum for the being of a thing [Locke, by Jones,J-E] |

| 15950 | We will only understand substance when we know the necessary connections between powers and qualities [Locke] |
| 9787 | Scientists must know the essential attributes of the things they study [Aristotle] |
| 7713 | We identify substances by supposing that groups of sensations arise from an essence [Locke] |
| 12545 | Other spirits may exceed us in knowledge, by knowing the inward constitution of things [Locke] |
| 12484 | Motion is just change of distance between two things [Locke] |
| 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] |
| 15986 | Boyle and Locke suspect forces of being occult [Locke, by Alexander,P] |
| 16685 | An insurmountable force in a body keeps our hands apart when we handle it [Locke] |
| 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] |
| 15980 | We can locate the parts of the universe, but not the whole thing [Locke] |
| 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] |
| 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] |
| 12486 | An 'instant' is where we perceive no succession, and is the time of a single idea [Locke] |
| 22968 | Circular motion is the most obvious measure of time, and especially the celestial sphere [Aristotle] |
| 12487 | We can never show that two successive periods of time were equal [Locke] |
| 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] |
| 12567 | It is inconceivable that unthinking matter could produce intelligence [Locke] |
| 5119 | The source of all movement must be indivisible and have no magnitude [Aristotle] |
| 12570 | The finite and dependent should obey the supreme and infinite [Locke] |
| 12565 | God has given us no innate idea of himself [Locke] |
| 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] |
