12056	An ancestral relation is either direct or transitively indirect [Wiggins]

	From: David Wiggins (Substance [1995], 4.10.1)
	A reaction: A concept invented by Frege (1879).

8. Modes of Existence / C. Powers and Dispositions / 4. Powers as Essence

12050	Substances contain a source of change or principle of activity [Wiggins]
	Full Idea: Substances are things that have a source of change or principle of activity within them.
	From: David Wiggins (Substance [1995], 4.4.1)
	A reaction: A vey significant concession. I think we can talk of 'essences' and 'powers', and drop talk of 'substances'. 'Powers' is a much better word, because it immediately pushes the active ingredient to the forefront.
