7 ideas

7. Existence / A. Nature of Existence / 6. Criterion for Existence

19393	What is not active is nothing [Leibniz]
	Full Idea: We can now show from the inner truths of metaphysics that what is not active is nothing.
	From: Gottfried Leibniz (True Method in Philosophy and Theology [1686], p.64)
	A reaction: This is Leibniz's rebellion against the Cartesian idea that all that matters for natural existence is spatial extension. I agree (tentatively) with Leibniz's vision of nature here. Modern physics reveals a seething turmoil beneath the placid exterior.

9. Objects / E. Objects over Time / 4. Four-Dimensionalism

11842	If short-lived happenings like car crashes are 'events', why not long-lived events like Dover Cliffs? [Broad]
	Full Idea: We call a lightning flash or a motor accident an event, but refuse to apply this to the cliffs of Dover. ...But quantitative differences (of time) give no good grounds for calling one bit of history an event, and refusing the name to another bit.
	From: C.D. Broad (Scientific Thought [1923], p.54), quoted by David Wiggins - Sameness and Substance Renewed 2.3 n13
	A reaction: Wiggins calls this proposal a 'terrible absurdity', but it seems to me to demand attention. There is a case to be made for a 'process' to be the fundamental category of our ontology, with stable physical objects seen in that light.

14759	A thing is simply a long event, linked by qualities, and spatio-temporal unity [Broad]
	Full Idea: A thing is simply a long event, throughout the course of which there is either qualitative similarity or continuous qualitative change, together with a characteristic spatio-temporal unity.
	From: C.D. Broad (Scientific Thought [1923], 10 'Duration')
	A reaction: At least he is trying to give some sort of principle that links the stages of the event together.

22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / e. Human nature

7667	There are two sides to men - the pleasantly social, and the violent and creative [Diderot, by Berlin]
	Full Idea: Diderot is among the first to preach that there are two men: the artificial man, who belongs in society and seeks to please, and the violent, bold, criminal instinct of a man who wishes to break out (and, if controlled, is responsible for works of genius.
	From: report of Denis Diderot (works [1769], Ch.3) by Isaiah Berlin - The Roots of Romanticism
	A reaction: This has an obvious ancestor in Plato's picture (esp. in 'Phaedrus') of the two conflicting sides to the psuché, which seem to be reason and emotion. In Diderot, though, the suppressed man has virtues, which Plato would deny.

27. Natural Reality / D. Time / 1. Nature of Time / g. Growing block

8160	The present and past exist, but the future does not [Broad, by Dummett]
	Full Idea: Not only the present but also the past exist, but the future (so long as it is the future) does not.
	From: report of C.D. Broad (Scientific Thought [1923]) by Michael Dummett - Thought and Reality 1
	A reaction: This is quite appealing, and seems right if you believe that every truth has a truthmaker, and that there are no truths about the future. And yet the whole misery of people dying is that they cease to exist.

14609	We could say present and past exist, but not future, so that each event adds to the total history [Broad]
	Full Idea: One theory accepts the reality of the present and the past, but holds that the future is simply nothing at all. Nothing has happened to the present by becoming past except that fresh slices of existence have been added to the total history of the world.
	From: C.D. Broad (Scientific Thought [1923], II)
	A reaction: This is now known as Broad's 'Growing Block' view of time. It is tempting to say that neither past nor future exist, but it seems undeniable that statements about the past can be wholly true, unlike those about the future.

27. Natural Reality / D. Time / 2. Passage of Time / d. Time series

22933	We imagine the present as a spotlight, moving across events from past to future [Broad]
	Full Idea: We imagine presentness moving, like the spot of light from a policeman's bulls eye traversing the fronts of houses in a street. What is illuminated is present, what was illuminated is past, and what is not yet illuminated is the future.
	From: C.D. Broad (Scientific Thought [1923], II)
	A reaction: This is the 'moving spotlight' compromise theory, which retains the B-series eternal sequence of ordered events, but adds the A-series privileged present moment. Le Poidevin says Broad represents time twice over.
