10. Modality / A. Necessity / 1. Types of Modality

14528	Maybe modal thought is unavoidable, as a priori recognition of necessary truth-preservation in reasoning [Hale/Hoffmann,A]
	Full Idea: There are 'transcendental' arguments saying that modal thought is unavoidable - recognition, a priori, of the necessarily truth-preserving character of some forms of inference is a precondition for rational thought in general, and scientific theorizing.
	From: Bob Hale/ Aviv Hoffmann (Introduction to 'Modality' [2010], 1)
	A reaction: So the debate about the status of logical truths and valid inference, are partly debates about whether out thought has to involve modality, or whether it could just be about the actual world. I take possibilities and necssities to be features of nature.

21. Aesthetics / C. Artistic Issues / 6. Value of Art

20436	Art leads to mental health, and mental clarity [Beardsley,M, by Carroll,N]
	Full Idea: Beardsley says aesthetic experience relieves tensions and quiet destructive emotions. It also aids us in sorting out the jumble in the flow of consciousness, by virtue of its tendencies toward heightened clarity and coherence.
	From: report of Monroe Beardsley (Aesthetics: problems in the philosophy of criticism [1958]) by Noël Carroll - Monroe Beardsley p.162-3
	A reaction: I find this claim highly implausible. I like art, but I feel neither healthier nor clearer after experiencing it.

27. Natural Reality / A. Classical Physics / 2. Thermodynamics / a. Energy

20646	Helmholtz used 'energy' to mathematically link heat, light, electricity and magnetism [Helmholtz, by Watson]
	Full Idea: Helmholtz provided the requisite mathematical formulation linking heat, light, electricity and magnetism, by treating these phenomena as different manifestations of 'energy'.
	From: report of Hermann von Helmholtz (On the Conservation of Force [1847]) by Peter Watson - Convergence 01 'Human'
	A reaction: I'm increasingly struck by the neglect by philosophers of nature of these amazing developments in 19th century physics, because they prefer the excitement of the latest nuclear physics. There is more philosophical interest in the earlier stages.

27. Natural Reality / A. Classical Physics / 2. Thermodynamics / c. Conservation of energy

20973	All forces conserve the sum of kinetic and potential energy [Helmholtz, by Papineau]
	Full Idea: Helmholtz crucially asserted that all forces conserve the sum of kinetic and potential energy; superficially non-conservative forces like friction are simply macroscopic manifestations of more fundamental forces conserving energy at the micro-level.
	From: report of Hermann von Helmholtz (On the Conservation of Force [1847]) by David Papineau - Thinking about Consciousness App 4.3
	A reaction: Friction had been a problem case, because it appeared not to conserve energy when it slowed movement down.
