46 ideas
13838 | A decent modern definition should always imply a semantics [Hacking] |
22309 | An idea can only be like another idea [Berkeley] |
13833 | 'Thinning' ('dilution') is the key difference between deduction (which allows it) and induction [Hacking] |
13834 | Gentzen's Cut Rule (or transitivity of deduction) is 'If A |- B and B |- C, then A |- C' [Hacking] |
13835 | Only Cut reduces complexity, so logic is constructive without it, and it can be dispensed with [Hacking] |
13845 | The various logics are abstractions made from terms like 'if...then' in English [Hacking] |
13840 | First-order logic is the strongest complete compact theory with Löwenheim-Skolem [Hacking] |
13844 | A limitation of first-order logic is that it cannot handle branching quantifiers [Hacking] |
13842 | Second-order completeness seems to need intensional entities and possible worlds [Hacking] |
13837 | With a pure notion of truth and consequence, the meanings of connectives are fixed syntactically [Hacking] |
13839 | Perhaps variables could be dispensed with, by arrows joining places in the scope of quantifiers [Hacking] |
13843 | If it is a logic, the Löwenheim-Skolem theorem holds for it [Hacking] |
6717 | Abstract ideas are impossible [Berkeley] |
18876 | Berkeley does believe in trees, but is confused about what trees are [Berkeley, by Cameron] |
3291 | Emergent properties appear at high levels of complexity, but aren't explainable by the lower levels [Nagel] |
6715 | Universals do not have single meaning, but attach to many different particulars [Berkeley] |
6719 | No one will think of abstractions if they only have particular ideas [Berkeley] |
6714 | Universals do not have any intrinsic properties, but only relations to particulars [Berkeley] |
6729 | Material substance is just general existence which can have properties [Berkeley] |
16636 | A die has no distinct subject, but is merely a name for its modes or accidents [Berkeley] |
6722 | Perception is existence for my table, but also possible perception, by me or a spirit [Berkeley] |
6724 | The only substance is spirit, or that which perceives [Berkeley] |
6723 | The 'esse' of objects is 'percipi', and they can only exist in minds [Berkeley] |
6732 | When I shut my eyes, the things I saw may still exist, but in another mind [Berkeley] |
6726 | No one can, by abstraction, conceive extension and motion of bodies without sensible qualities [Berkeley] |
6728 | Motion is in the mind, since swifter ideas produce an appearance of slower motion [Berkeley] |
6727 | Figure and extension seem just as dependent on the observer as heat and cold [Berkeley] |
6495 | Berkeley's idealism resulted from fear of scepticism in representative realism [Robinson,H on Berkeley] |
6720 | Knowledge is of ideas from senses, or ideas of the mind, or operations on sensations [Berkeley] |
23636 | Berkeley's idealism gives no grounds for believing in other minds [Reid on Berkeley] |
6736 | I know other minds by ideas which are referred by me to other agents, as their effects [Berkeley] |
6713 | If animals have ideas, and are not machines, they must have some reason [Berkeley] |
6491 | Berkeley replaced intentionality with an anti-abstractionist imagist theory of thought [Berkeley, by Robinson,H] |
6711 | The mind creates abstract ideas by considering qualities separated from their objects [Berkeley] |
10581 | I can only combine particulars in imagination; I can't create 'abstract' ideas [Berkeley] |
6721 | Ideas are perceived by the mind, soul or self [Berkeley] |
6716 | Language is presumably for communication, and names stand for ideas [Berkeley] |
6718 | I can't really go wrong if I stick to wordless thought [Berkeley] |
6731 | No one can explain how matter affects mind, so matter is redundant in philosophy [Berkeley] |
6730 | We discover natural behaviour by observing settled laws of nature, not necessary connections [Berkeley] |
3290 | Given the nature of heat and of water, it is literally impossible for water not to boil at the right heat [Nagel] |
15861 | The laws of nature are mental regularities which we learn by experience [Berkeley] |
6734 | If properties and qualities arise from an inward essence, we will remain ignorant of nature [Berkeley] |
6735 | All motion is relative, so a single body cannot move [Berkeley] |
6733 | I cannot imagine time apart from the flow of ideas in my mind [Berkeley] |
6737 | Particular evils are really good when linked to the whole system of beings [Berkeley] |
