Vector/Newton/Bigelow/Pargetter: a vector explains the positions of the object, not vice versa.
Problem: this seems to require the assumption that a body could have a velocity without taking several positions.
Solution/Bigelow/Pargetter: the connection between velocity and positions is created so that the vector explains the change of position, not because it is defined by the change.

Independence/Explanation/Science/Bigelow/Pargetter: logical independence must not be pushed to the point where there is no relevant link between the entities. (Here properties of the 1st and 2nd level).

Independence/Movement/before/after/Pre-history/Determination/Ockhamists/Bigelow/Pargetter: Problem: at the top of a parabola (trajectory of a projectile), the body moves horizontally, but this is not independent of the before and after.
Flux/Vector/Newton/Bigelow/Pargetter: considers the movement at this point as independent. There is at least one logical independence.
Velocity/Newton/Bigelow/Pargetter: can be completely independent of 2nd level properties: e.g. transmission of velocities by impact. (+...)
I 68
Consistency/Newton/Bigelow/Pargetter: after that, it is not even absurd to attribute a velocity of 0 to a body that does not move noticeably.
Vector/Newton/Bigelow/Pargetter: therefore, it is not logically necessary that a vector is linked to attributes that change over time.
Change of location/Ockham/Bigelow/Pargetter: when we look at the sequence of positions in time, the Ockhamists do not imply instantaneous velocity (entails).

Malebranche/Change/Movement/Bigelow/Pargetter: (Ockhamist): according to Malebranche, God creates the object anew at every point. This is not a causal process.
