4 ideas

13. Knowledge Criteria / C. External Justification / 2. Causal Justification

11052	Psychological logic can't distinguish justification from causes of a belief [Frege]
	Full Idea: With the psychological conception of logic we lose the distinction between the grounds that justify a conviction and the causes that actually produce it.
	From: Gottlob Frege (Logic [1897] [1897])
	A reaction: Thus Frege kicked the causal theory of justification well into touch long before it had even been properly formulated. That is not to say that there is no psychological aspect to logic, because there is.

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.

22. Metaethics / B. Value / 2. Values / g. Love

15998	Perfect love is not in spite of imperfections; the imperfections must be loved as well [Kierkegaard]
	Full Idea: To love another in spite of his weaknesses and errors and imperfections is not perfect love. No, to love is to find him lovable in spite of, and together with, his weaknesses and errors and imperfections.
	From: Søren Kierkegaard (Works of Love [1847], p.158)
	A reaction: A true romantic at heart, Kierkegaard ideally posits perfect love as unconditional love, and not just of good attributes, predicates and conditions. However, the real question for both me and Kierkegaard is, is perfect love desirable or even possible?[SY]

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.
