7. Existence / B. Change in Existence / 2. Processes
Slow and continuous events (like balding or tree-growth) are called 'processes', not 'events' [Simons]
     Full Idea: Some changes are slow and continuous and are called 'processes' rather than events; the growth of a tree or the greying of John's hair.
     From: Peter Simons (Events [2003], 3.2)
     A reaction: So making a loaf of bread is an event rather than a process, and World War I was a process rather than an event? If you slow down a dramatic event (on film), you see that it is really a process. I take 'process' to be a much more illuminating word.
Maybe processes behave like stuff-nouns, and events like count-nouns [Simons]
     Full Idea: There is arguably a parallel between the mass-count distinction among meanings of nouns and the process-event distinction among meanings of verbs. Processes, like stuff, do not connote criteria for counting, whereas events, like things, do.
     From: Peter Simons (Events [2003], 6.2)
     A reaction: Hm. You can have several processes, and a process can come to an end - but then you can have several ingredients of a cake, and you can run out of one of them. This may be quite a helpful distinction.
7. Existence / B. Change in Existence / 4. Events / a. Nature of events
Einstein's relativity brought events into ontology, as the terms of a simultaneity relationships [Simons]
     Full Idea: The ontology of events rose in philosophy with the rise of relativity theory in physics. Einstein postulated the relativity of simultaneity to an observer's state of motion. The terms of the relation of simultaneity must be events or their parts.
     From: Peter Simons (Events [2003], 1.1.2)
     A reaction: Intriguing. Philosophers no doubt think they are way ahead of physicists in such a metaphysical area. Personally I regard the parentage of the concept as good grounds for scepticism about it. See Idea 7621 for my reason.
9. Objects / D. Essence of Objects / 9. Essence and Properties
How do we tell a table's being contingently plastic from its being essentially plastic? [Jackson]
     Full Idea: On a friendly reading of Quine, there is nothing to make the difference between a table's being contingently plastic and its being essentially plastic.
     From: Frank Jackson (Possible Worlds and Necessary A Posteriori [2010], 5)
     A reaction: This is, of course, the dreaded modern usage of 'essential' to just mean 'necessary' and nothing more. In my view, there may be a big problem with knowing whether a problem is necessary, but knowing whether it is essential is much easier.
An x is essentially F if it is F in every possible world in which it appears [Jackson]
     Full Idea: On the possible world's account, x's being essentially F is nothing more nor less than x's being F in every world in which it appears.
     From: Frank Jackson (Possible Worlds and Necessary A Posteriori [2010], 6)
     A reaction: There you go - 'true in every possible world' is the definition of metaphysical necessity, not the definition of essence. Either get back to Aristotle, or stop (forever!) talking about 'essence'!
9. Objects / D. Essence of Objects / 15. Against Essentialism
Quine may have conflated de re and de dicto essentialism, but there is a real epistemological problem [Jackson]
     Full Idea: The unfriendly response to Quine's objection to essentialism is that it conflates the de re and the de dicto. The friendly response is that behind that conflation is a real epistemological problem for essentialism.
     From: Frank Jackson (Possible Worlds and Necessary A Posteriori [2010], 1)
     A reaction: He cites Richard Cartwright 1968 for the friendly response. The epistemological question is how we can know the essentialness of an essence.
10. Modality / D. Knowledge of Modality / 3. A Posteriori Necessary
How can you show the necessity of an a posteriori necessity, if it might turn out to be false? [Jackson]
     Full Idea: If something is offered as a candidate necessary a posteriori truth, how could we show that it is necessary, in the face of the fact that it takes investigation to show that it is true, and so, in some sense, it might have turned out to be false?
     From: Frank Jackson (Possible Worlds and Necessary A Posteriori [2010], 1)
     A reaction: This is the topic of his paper, which he compares with how we can know that essences are essential.
10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / a. Conceivable as possible
How do you know you have conceived a thing deeply enough to assess its possibility? [Vaidya]
     Full Idea: The main issue with learning possibility from conceivability concerns how we can be confident that we have conceived things to the relevant level of depth required for the scenario to actually be a presentation or manifestation of a genuine possibility.
     From: Anand Vaidya (The Epistemology of Modality [2015], 1.2.2)
     A reaction: [He cites Van Inwagen 1998 for this idea] The point is that ignorant imagination can conceive of all sorts of absurd things which are seen to be impossible when enough information is available. We can hardly demand a criterion for this.
