5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / c. not

18801	Classical negation is circular, if it relies on knowing negation-conditions from truth-conditions [Dummett]
	Full Idea: Explanations of classical negation assume that knowing what it is for the truth-condition of some statement to obtain, independently of recognising it to obtain, we thereby know what it is for it NOT to obtain; but this presupposes classical negation.
	From: Michael Dummett (The Logical Basis of Metaphysics [1991], p.299), quoted by Ian Rumfitt - The Boundary Stones of Thought 1.1
	A reaction: [compressed wording] This is Dummett explaining why he prefers intuitionistic logic, with its doubts about double negation.

11. Knowledge Aims / C. Knowing Reality / 3. Idealism / d. Absolute idealism

21912	Fichte, Schelling and Hegel rejected transcendental idealism [Lewis,PB]
	Full Idea: Fichte, Schelling and Hegel were united in their opposition to Kant's Transcendental Idealism.
	From: Peter B. Lewis (Schopenhauer [2012], 3)
	A reaction: That is, they preferred genuine idealism, to the mere idealist attitude Kant felt that we are forced to adopt.

21911	Fichte, Hegel and Schelling developed versions of Absolute Idealism [Lewis,PB]
	Full Idea: At the University of Jena, Fichte, Hegel and Schelling critically developed aspects of Kant's philosophy, each in his own way, thereby giving rise to the movement known as Absolute Idealism, see reality as universal God-like self-consciousness.
	From: Peter B. Lewis (Schopenhauer [2012], 2)
	A reaction: Is asking how anyone can possibly have believed such a bizarre and ridiculous idea a) uneducated, b) stupid, c) unimaginative, or d) very sensible? It sounds awfully like Spinoza's concept of God. Also Anaxagoras.

22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / j. Ethics by convention

6017	Nomos is king [Pindar]
	Full Idea: Nomos is king.
	From: Pindar (poems [c.478 BCE], S 169), quoted by Thomas Nagel - The Philosophical Culture
	A reaction: This seems to be the earliest recorded shot in the nomos-physis wars (the debate among sophists about moral relativism). It sounds as if it carries the full relativist burden - that all that matters is what has been locally decreed.
