4 ideas

7. Existence / D. Theories of Reality / 8. Facts / b. Types of fact

15201	That Queen Anne is dead is a 'general fact', not a fact about Queen Anne [Prior,AN]
	Full Idea: The fact that Queen Anne has been dead for some years is not, in the strict sense of 'about', a fact about Queen Anne; it is not a fact about anyone or anything - it is a general fact.
	From: Arthur N. Prior (Changes in Events and Changes in Things [1968], p.13), quoted by Robin Le Poidevin - Past, Present and Future of Debate about Tense 1 b
	A reaction: He distinguishes 'general facts' (states of affairs, I think) from 'individual facts', involving some specific object. General facts seem to be what are expressed by negative existential truths, such as 'there is no Loch Ness Monster'. Useful.

9. Objects / D. Essence of Objects / 7. Essence and Necessity / b. Essence not necessities

13166	Essences are no use in mathematics, if all mathematical truths are necessary [Mancosu]
	Full Idea: Essences and essential properties do not seem to be useful in mathematical contexts, since all mathematical truths are regarded as necessary (though Kit Fine distinguishes between essential and necessary properties).
	From: Paolo Mancosu (Explanation in Mathematics [2008], §6.1)
	A reaction: I take the proviso in brackets to be crucial. This represents a distortion of notion of an essence. There is a world of difference between the central facts about the nature of a square and the peripheral inferences derivable from it.

16. Persons / F. Free Will / 5. Against Free Will

19413	If we know what is good or rational, our knowledge is extended, and our free will restricted [Leibniz]
	Full Idea: The more perfect one is, the more one is determined to the good, and so is more free at the same time. ...Our power and knowledge are more extended, and our will much the more limited within the bounds of perfect reason.
	From: Gottfried Leibniz (Letters to Pierre Bayle [1702], 1702)
	A reaction: I like this idea, which seems to me to derive from Aquinas. When I choose to eat and drink each day, or agree that 7+5 is 12, I don't complain about my lack of freedom in the choices. Goodness and reason are constraints I welcome.

27. Natural Reality / D. Time / 2. Passage of Time / e. Tensed (A) series

22899	'Thank goodness that's over' is not like 'thank goodness that happened on Friday' [Prior,AN]
	Full Idea: One says 'thank goodness that is over', ..and it says something which it is impossible which any use of any tenseless copula with a date should convey. It certainly doesn't mean the same as 'thank goodness that occured on Friday June 15th 1954'.
	From: Arthur N. Prior (Changes in Events and Changes in Things [1968]), quoted by Adrian Bardon - Brief History of the Philosophy of Time 4 'Pervasive'
	A reaction: [Ref uncertain] This seems to be appealing to ordinary usage, in which tenses have huge significance. If we take time (with its past, present and future) as primitive, then tenses can have full weight. Did tenses mean anything at all to Einstein?
