I explained my reasoning by saying that the words ‘principis agi..t’ derived, in my opinion, from the Latin ‘ago’, ‘to drive’ or ‘put in motion’, and that this translated as ‘principle of motion or movement’, however Stewart's work on the translation has persuaded me that his translation, 'connectedness principle' is correct and it seems to fit better with the preceeding text.
I've had some more thoughts about this phrase and I think one can infer that it refers to either a connection between two objects or an interconnection between several. I prefer the idea of two-part connections because I think he would have used some word such as interconnectedness to describe a connection between several objects. He also states that his weights worked in pairs, and that seems to fit. But what else can we gather from the phrase?
Connectedness implies a degree of connection somewhat less than a full connection and I'm thinking of something like, for instance, a length of rope between ones-self and a heavy object. You can pull it but you can't push it, so it's a one-way connection. My research has has shown how this is used in Bessler's wheel and he has used two similar arrangement for moving weights in both direction but only pushing them, and then he allows one hald of the pair of weights to return under its own steam and the other is brought back by the pull-not-push method.
But there is another version of the pull-not-push which gives additional advantages. Using a lever which is articulated or hinged a point between the two ends allows one to pull another object but also to push it and, with the desired proportions, to push it with extra force over a shorter distance. A combination of these features is used in Bessler's wheel.
