11. Knowledge Aims / A. Knowledge / 2. Understanding

19542	It is nonsense that understanding does not involve knowledge; to understand, you must know [Dougherty/Rysiew]
	Full Idea: The proposition that understanding does not involve knowledge is widespread (for example, in discussions of what philosophy aims at), but hardly withstands scrutiny. If you do not know how a jet engine works, you do not understand how it works.
	From: Dougherty,T/Rysiew,P (Experience First (and reply) [2014], p.24)
	A reaction: This seems a bit disingenuous. As in 'Theaetetus', knowing the million parts of a jet engine is not to understand it. More strongly - how could knowledge of an infinity of separate propositional truths amount to understanding on their own?

19543	To grasp understanding, we should be more explicit about what needs to be known [Dougherty/Rysiew]
	Full Idea: An essential prerequisite for useful discussion of the relation between knowledge and understanding is systematic explicitness about what is to be known or understood.
	From: Dougherty,T/Rysiew,P (Experience First (and reply) [2014], p.25)
	A reaction: This is better. I say what needs to be known for understanding is the essence of the item under discussion (my PhD thesis!). Obviously understanding needs some knowledge, but I take it that epistemology should be understanding-first. That is the main aim.

11. Knowledge Aims / A. Knowledge / 7. Knowledge First

19541	Rather than knowledge, our epistemic aim may be mere true belief, or else understanding and wisdom [Dougherty/Rysiew]
	Full Idea: If we say our cognitive aim is to get knowledge, the opposing views are the naturalistic view that what matters is just true belief (or just 'getting by'), or that there are rival epistemic goods such as understanding and wisdom.
	From: Dougherty,T/Rysiew,P (Experience First (and reply) [2014], p.17)
	A reaction: [compressed summary] I'm a fan of understanding. The accumulation of propositional knowledge would relish knowing the mass of every grain of sand on a beach. If you say the propositions should be 'important', other values are invoked.

17. Mind and Body / B. Behaviourism / 2. Potential Behaviour

7435	Dispositions are second-order properties, the property of having some property [Jackson/Pargetter/Prior, by Armstrong]
	Full Idea: It was proposed that dispositions are second-order properties of objects: the property of having some property.
	From: report of Jackson/Pargetter/Prior (Three theses about dispositions [1982]) by David M. Armstrong - Pref to new 'Materialist Theory' p.xvii
	A reaction: It seems more plausible to say that dispositions are first-order properties - that is, properties are dispositions, which are causal powers. A disposition to smoke is to have a causal power which leads to smoking.

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.
