12. Knowledge Sources / B. Perception / 4. Sense Data / d. Sense-data problems
Sense-data are dubious abstractions, with none of the plausibility of tables [Quine]
     Full Idea: The notion of pure sense datum is a pretty tenuous abstraction, a good deal more conjectural than the notion of an external object, a table or a sheep.
     From: Willard Quine (On Mental Entities [1952], p.225)
     A reaction: This seems to sum up the view of sense-data held by the generation after Russell and Moore. Ayer still talks about them, but Russell had already given them up. The simple challenge is - what is the evidence for their existence? Cf innate ideas.
12. Knowledge Sources / D. Empiricism / 4. Pro-Empiricism
Empiricism says evidence rests on the senses, but that insight is derived from science [Quine]
     Full Idea: The crucial insight of empiricism is that any evidence for science has its end points in the senses. This insight remains valid, but it is an insight which comes after physics, physiology, and psychology, not before.
     From: Willard Quine (On Mental Entities [1952], p.225)
     A reaction: Interesting. I think Hume and co. were probably outlining essential presuppositions and contraints which must be accepted by science. Quine offers empiricism as more like a description of science (with success as its authority?).
14. Science / D. Explanation / 2. Types of Explanation / h. Explanations by function
To explain a house we must describe its use, as well as its parts [Leibniz]
     Full Idea: A house would be badly explained if we were to describe only the arrangement of its parts, but not its use.
     From: Gottfried Leibniz (On Body and Force, Against the Cartesians [1702], p.255)
     A reaction: This must partly fall under pragmatics (i.e. what the enquirer is interested in). But function plays a genuine role in artefacts, and also in evolved biological organs.
15. Nature of Minds / C. Capacities of Minds / 10. Conatus/Striving
Active force is not just potential for action, since it involves a real effort or striving [Leibniz]
     Full Idea: Active force should not be thought of as the simple and common potential [potentia] or receptivity to action of the schools. Rather, active force involves an effort [conatus] or striving [tendentia] toward action.
     From: Gottfried Leibniz (On Body and Force, Against the Cartesians [1702], p.252)
     A reaction: This is why Leibniz is lured into making his active forces more and more animistic, till they end up like proto-minds (though never, remember, conscious and willing minds).
26. Natural Theory / D. Laws of Nature / 1. Laws of Nature
God's laws would be meaningless without internal powers for following them [Leibniz]
     Full Idea: To say that, in creation, God gave bodies a law for acting means nothing, unless, at the same time, he gave them something by means of which it could happen that the law is followed.
     From: Gottfried Leibniz (On Body and Force, Against the Cartesians [1702], p.253)
     A reaction: This is the beginning of the modern rebellion against the medieval view of laws as imposed from outside on passive matter. Unfortunately for Leibniz, once you have postulated active internal powers, the external laws become redundant.
27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces
All qualities of bodies reduce to forces [Leibniz]
     Full Idea: All qualities of bodies .....are in the end reduced [revoco] to forces.
     From: Gottfried Leibniz (On Body and Force, Against the Cartesians [1702], p.256)
     A reaction: The dots conceal a long qualification, but he is essentially standing by this simple remark. If you substitute the word 'powers' for 'forces', I think that is just about right.
Power is passive force, which is mass, and active force, which is entelechy or form [Leibniz]
     Full Idea: The dynamicon or power [potentia] in bodies is twofold, passive and active. Passive force [vis] constitutes matter or mass [massa], and active force constitutes entelechy or form.
     From: Gottfried Leibniz (On Body and Force, Against the Cartesians [1702], p.252)
     A reaction: This is explicitly equating the innate force understood in physics with Aristotelian form. The passive force is to explain the resistance of bodies. I like the equation of force with power. He says the entelechy is 'analogous' to a soul.
29. Religion / D. Religious Issues / 2. Immortality / a. Immortality
Resurrection developed in Judaism as a response to martyrdoms, in about 160 BCE [Anon (Dan), by Watson]
     Full Idea: The idea of resurrection in Judaism seems to have first developed around 160 BCE, during the time of religious martyrdom, and as a response to it (the martyrs were surely not dying forever?). It is first mentioned in the book of Daniel.
     From: report of Anon (Dan) (27: Book of Daniel [c.165 BCE], Ch.7) by Peter Watson - Ideas
     A reaction: Idea 7473 suggests that Zoroaster beat them to it by 800 years.
