6 ideas

1. Philosophy / D. Nature of Philosophy / 1. Philosophy

7848	Philosophy begins in the horror and absurdity of existence [Nietzsche, by Ansell Pearson]
	Full Idea: For Nietzsche philosophy begins in horror - existence is something both horrible and absurd.
	From: report of Friedrich Nietzsche (The Birth of Tragedy [1871]) by Keith Ansell Pearson - How to Read Nietzsche Ch.1
	A reaction: A striking contrast to Aristotle (Idea 549). Personally I think my philosophy begins with confusion. Not that I endorse a Wittgenteinian view, that we are just trying to cure ourselves of self-inflicted wounds. Life is very complex and we are bit simple.

2. Reason / D. Definition / 1. Definitions

19426	'Nominal' definitions just list distinguishing characteristics [Leibniz]
	Full Idea: A 'nominal' definition is nothing more than an enumeration of the sufficient distinguishing characteristics.
	From: Gottfried Leibniz (Reflections on Knowledge, Truth and Ideas [1684], p.284)
	A reaction: Not wholly clear. Are these actual distinguishing characteristics, or potential ones? Could DNA be part of a human's nominal definition (for an unidentified corpse, perhaps).

11. Knowledge Aims / A. Knowledge / 1. Knowledge

19424	Knowledge needs clarity, distinctness, and adequacy, and it should be intuitive [Leibniz]
	Full Idea: Knowledge is either obscure or clear; clear ideas are either indistinct or distinct; distinct ideas are either adequate or inadequate, symbolic or intuitive; perfect knowledge is that which is both adequate and intuitive.
	From: Gottfried Leibniz (Reflections on Knowledge, Truth and Ideas [1684], p.283)
	A reaction: This is Leibniz's expansion of Descartes's idea that knowledge rests on 'clear and distinct conceptions'. The ultimate target seems to be close to an Aristotelian 'real definition', which is comprehensive and precise. Does 'intuitive' mean coherent?

18. Thought / C. Content / 2. Ideas

19427	True ideas represent what is possible; false ideas represent contradictions [Leibniz]
	Full Idea: An idea is true if what it represents is possible; false if the representation contains a contradiction.
	From: Gottfried Leibniz (Reflections on Knowledge, Truth and Ideas [1684], p.287)
	A reaction: Odd in the analytic tradition to talk of a single idea or concept (rather than a proposition or utterance) as being 'true'. But there is clearly a notion of valid or legitimate or useful concepts here. Hilbert said true just meant non-contradictory.

26. Natural Theory / C. Causation / 2. Types of cause

19425	In the schools the Four Causes are just lumped together in a very obscure way [Leibniz]
	Full Idea: In the schools the four causes are lumped together as material, formal, efficient, and final causes, but they have no clear definitions, and I would call such a judgment 'obscure'.
	From: Gottfried Leibniz (Reflections on Knowledge, Truth and Ideas [1684], p.283)
	A reaction: He picks this to illustrate what he means by 'obscure', so he must feel strongly about it. Elsewhere Leibniz embraces efficient and final causes, but says little of the other two. This immediately become clearer as the Four Modes of Explanation.

27. Natural Reality / C. Space / 6. Space-Time

14014	Space alone, and time alone, will fade away, and only their union has an independent reality [Minkowski]
	Full Idea: Henceforth, space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.
	From: Hermann Minkowski (Space and Time [1908], Intro)
	A reaction: Notice the qualification that it is a 'kind of' union. Deep confusion arises from exaggerating the analogy between space and time. Craig Bourne remarks (2006:157) that this shows independence of measurement, not of reality
