4 ideas

14. Science / B. Scientific Theories / 1. Scientific Theory

22363	You have only begun to do real science when you can express it in numbers [Kelvin]
	Full Idea: When you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.
	From: Lord Kelvin (Wm Thomson) (works [1881]), quoted by Reiss,J/Spreger,J - Scientific Objectivity 4.1
	A reaction: [Popular Lectures 1 p.73] Clearly the writer is a physicist! Astronomers discover objects, geologists discover structures, biologists reveal mechanisms.

19. Language / D. Propositions / 3. Concrete Propositions

19216	Propositions (such as 'that dog is barking') only exist if their items exist [Williamson]
	Full Idea: A proposition about an item exists only if that item exists... how could something be the proposition that that dog is barking in circumstances in which that dog does not exist?
	From: Timothy Williamson (Necessary Existents [2002], p.240), quoted by Trenton Merricks - Propositions
	A reaction: This is a view of propositions I can't make sense of. If I'm under an illusion that there is a dog barking nearby, when there isn't one, can I not say 'that dog is barking'? If I haven't expressed a proposition, what have I done?

24. Political Theory / D. Ideologies / 10. Theocracy

7825	The politics of Leibniz was the reunification of Christianity [Stewart,M]
	Full Idea: The politics of Leibniz may be summed up in one word: theocracy. The specific agenda motivating much of his work was to reunite the Protestant and Catholic churches
	From: Matthew Stewart (The Courtier and the Heretic [2007], Ch. 5)
	A reaction: This would be a typical project for a rationalist philosopher, who thinks that good reasoning will gradually converge on the one truth.

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

20644	Energy has progressed from a mere formula, to a principle pervading all nature [Kelvin]
	Full Idea: The name 'energy', first used by Thomas Young, has come into use after it was raised from a mere formula of mathematical dynamics to become a principle pervading all nature, and guiding every field of science.
	From: Lord Kelvin (Wm Thomson) (works [1881]), quoted by Peter Watson - Convergence 01 'Principle'
	A reaction: [bit compressed] As far as I can see energy behaves exactly as if it were a substance, like water conserved in rainfalls, and yet it isn't a stuff, and seems to result from a process of abstraction. I take it to be one of the biggest mysteries in physics.
