4 ideas

2. Reason / A. Nature of Reason / 2. Logos

6294	In the beginning was the Word, and the Word was with God, and the word was God [John]
	Full Idea: In the beginning was the Word, and the Word was with God, and the word was God.
	From: St John (04: Gospel of St John [c.95], 01.01)
	A reaction: 'Word' translates the Greek word 'logos', which has come a long way since Heraclitus. The interesting contrast is with the later Platonist view that the essence of God is the Good. So is the source of everything to be found in reason, or in value?

3. Truth / A. Truth Problems / 2. Defining Truth

8821	Jesus said he bore witness to the truth. Pilate asked, What is truth? [John]
	Full Idea: Jesus: I came into the world, that I should bear witness unto the truth. Everyone that is of the truth heareth my voice. Pilate saith unto him, What is truth?
	From: St John (04: Gospel of St John [c.95], 18:37-8)
	A reaction: There is very little explicit discussion of truth in philosophy before this exchange (apart from Ideas 251 and 586), and there isn't any real debate prior to Russell and the pragmatists. What was Pilate's tone? Did he spit at the end of his question?

5. Theory of Logic / D. Assumptions for Logic / 4. Identity in Logic

3299	In logic identity involves reflexivity (x=x), symmetry (if x=y, then y=x) and transitivity (if x=y and y=z, then x=z) [Baillie]
	Full Idea: In logic identity is an equivalence relation, which involves reflexivity (x=x), symmetry (if x=y, then y=x), and transitivity (if x=y and y=z, then x=z).
	From: James Baillie (Problems in Personal Identity [1993], Intr p.4)

15. Nature of Minds / B. Features of Minds / 1. Consciousness / e. Cause of consciousness

4921	Quantum states in microtubules could bind brain activity to produce consciousness [Penrose]
	Full Idea: I propose that microtubules in nerve cells could give rise to a stable quantum state that would bind the activity of brain cells throughout the cerebrum and in doing so give rise to consciousness.
	From: Roger Penrose (Could a computer ever understand? [1998], p.329)
	A reaction: This seems to offer a physical theory to account for the 'unity' of the mind (which so impressed Descartes), but I don't quite see why being aware of things would ensue from some 'quantum binding'. I daresay 'quantum binding' occurs in the Sun.
