7 ideas

27. Natural Reality / A. Classical Physics / 1. Mechanics / a. Explaining movement
Motion is just change of distance between two things [Locke]
     Full Idea: Motion is nothing but change of distance between two things.
     From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 2.13.14)
     A reaction: If a thing moved steadily relative to other objects, and we then removed all other objects in the universe, would it still be moving?
27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces
Boyle and Locke suspect forces of being occult [Locke, by Alexander,P]
     Full Idea: I believe that both Boyle and Locke were suspicious of forces, regarding them as occult.
     From: report of John Locke (Essay Conc Human Understanding (2nd Ed) [1694]) by Peter Alexander - Ideas, Qualities and Corpuscles 7
     A reaction: I take this to be key difference between these two and Leibniz, with the latter on the side of the angels.
An insurmountable force in a body keeps our hands apart when we handle it [Locke]
     Full Idea: The bodies which we daily handle make us perceive that they do by an insurmountable force hinder the approach of the parts of our hands that press them.
     From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 2.04.01)
     A reaction: This is interesting for a rare use of the word 'force' by Locke. I like the empiricist approach to these things, of actually contemplating handling physical objects. Empiricism keeps the feet of philosophy firmly on the ground.
27. Natural Reality / C. Space / 5. Relational Space
We can locate the parts of the universe, but not the whole thing [Locke]
     Full Idea: We have no idea of the place of the universe, though we can of all the parts of it.
     From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 2.13.10)
     A reaction: Locke evidently agrees with the Leibniz view of space as relative, rather than with Newton's absolute view. …But see Idea 15981.
27. Natural Reality / D. Time / 3. Parts of Time / b. Instants
An 'instant' is where we perceive no succession, and is the time of a single idea [Locke]
     Full Idea: A part of duration wherein we perceive no succession, is that which we may call an 'instant'; and is that which takes up the time of only one idea in our minds.
     From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 2.14.10)
     A reaction: Given that the present appears to have zero duration (if it is where past and future meet), then this strikes me as a pretty accurate account of what we mean by an instant.
27. Natural Reality / D. Time / 3. Parts of Time / d. Measuring time
We can never show that two successive periods of time were equal [Locke]
     Full Idea: Two successive lengths of duration, however measured, can never be demonstrated to be equal.
     From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 2.14.21)
     A reaction: Nice thought. You can't lay the durations next to one another, the way you can lengths. You can only count the clock ticks, but not be sure whether their speed remained constant.
27. Natural Reality / G. Biology / 3. Evolution
It is inconceivable that unthinking matter could produce intelligence [Locke]
     Full Idea: It is as impossible to conceive that ever bare incogitative matter should produce a thinking intelligent being, as that nothing should of itself produce matter.
     From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.10.10)
     A reaction: This is still a strongly intuitive objection that some people have to materialistic evolution. If you don't think the mind can be reduced to the physical, you still have this problem. You'll probably have to concoct an idea called 'emergence'.
