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]
