4 ideas

9. Objects / D. Essence of Objects / 5. Essence as Kind

13074	Only natural kinds and their members have real essences [Suárez, by Cover/O'Leary-Hawthorne]
	Full Idea: On Suarez's account, only natural kinds and their members have real essences.
	From: report of Francisco Suárez (works [1588]) by Cover,J/O'Leary-Hawthorne,J - Substance and Individuation in Leibniz 1.3.1 n21
	A reaction: Interesting. Rather than say that everything is a member of some kind, we leave quirky individuals out, with no essence at all. What is the status of the very first exemplar of a given kind?

21. Aesthetics / C. Artistic Issues / 7. Art and Morality

468	Musical performance can reveal a range of virtues [Damon of Ath.]
	Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice.
	From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where?

26. Natural Theory / C. Causation / 4. Naturalised causation

7563	The old 'influx' view of causation says it is a flow of accidental properties from A to B [Suárez, by Jolley]
	Full Idea: The 'influx' model of causation says that causes involve a process of contagion, as it were; when the kettle boils, the gas infects the water inside the kettle with its own 'individual accident' of heat, which literally flows from one to the other.
	From: report of Francisco Suárez (works [1588]) by Nicholas Jolley - Leibniz Ch.2
	A reaction: This nicely captures the scholastic target of Hume's sceptical thinking on the subject. However, see Idea 2542, where the idea of influx has had a revival. It is hard to see how the water could change if it didn't 'catch' something from the gas.

27. Natural Reality / B. Modern Physics / 1. Relativity / a. Special relativity

12709	Motion is not absolute, but consists in relation [Leibniz]
	Full Idea: In reality motion is not something absolute, but consists in relation.
	From: Gottfried Leibniz (On Motion [1677], A6.4.1968), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 3
	A reaction: It is often thought that motion being relative was invented by Einstein, but Leibniz wholeheartedly embraced 'Galilean relativity', and refused to even consider any absolute concept of motion. Acceleration is a bit trickier than velocity.
