1. “Attraction” as in Newton’s supernatural cause.
   

[From Newton’s commentary on his Definitions, 6, 7, and 8. Densmore p. 21]

1. Further, I call attractions and impulses accelerative and motive in the same sense.
   
2. Morover, I use the words “attraction”, “impulse” or [words denoting] a propensity of any kind toward a center, indifferently and promiscuously for each other; I am considering these forces, not physically, but only mathematically.
   
3. Therefore, the reader should beware of thinking that by words of this kind I am anywhere defining a species or manner of action, or a cause or physical account, or that I am truly and physically attributing forces to centers (which are mathematical points) if I should happen to say either that centers attract, or that centers belong to centers.
