Single Idea 15962

[filed under theme 12. Knowledge Sources / B. Perception / 2. Qualities in Perception / d. Secondary qualities ]

Full Idea

Perhaps Boyle's most important technical terms is 'texture'. ...It must not be confused with the way we feel the texture of a surface like sandpaper or velvet; it is rather a structure of unobservable particles and so it is not directly observable.

Gist of Idea

Boyle's term 'texture' is not something you feel, but is unobservable structures of particles

Source

report of Robert Boyle (The Origin of Forms and Qualities [1666]) by Peter Alexander - Ideas, Qualities and Corpuscles 03.2

A Reaction

This is the basis for Alexander's reassessment of what Boyle and Locke meant by a 'secondary quality', which, he says, is a physical feature of objects, not a mental experience.


The 13 ideas from Robert Boyle

Boyle's secondary qualities are not illusory, or 'in the mind' [Boyle, by Alexander,P]
Boyle attacked a contemporary belief that powers were occult things [Boyle, by Alexander,P]
In the 17th century, 'disposition' usually just means the spatial arrangement of parts [Boyle, by Pasnau]
Boyle's term 'texture' is not something you feel, but is unobservable structures of particles [Boyle, by Alexander,P]
The corpuscles just have shape, size and motion, which explains things without 'sympathies' or 'forces' [Boyle, by Alexander,P]
The corpuscular theory allows motion, but does not include forces between the particles [Boyle, by Alexander,P]
Form is not a separate substance, but just the manner, modification or 'stamp' of matter [Boyle]
Essential definitions show the differences that discriminate things, and make them what they are [Boyle]
Explanation is deducing a phenomenon from some nature better known to us [Boyle]
To cite a substantial form tells us what produced the effect, but not how it did it [Boyle]
Explanation is generally to deduce it from something better known, which comes in degrees [Boyle]
The best explanations get down to primary basics, but others go less deep [Boyle]
I don't see how mere moving matter can lead to the bodies of men and animals, and especially their seeds [Boyle]
