I would think they would use the language of mathematics, and I'm not sure how it would contribute to an understanding of emergence. Others whose knowledge of geometry is fresher than mine could explain it better, but basically, once the length of the sides of a triangle is fixed, by drivin

Its an application of basic geometry. If the struts of the triangle are made of materials that do not stretch, compress, or flex (outside of acceptable parameters for the construction in question), then the triangle is *stable*--even if the joints are frictionless pivots. This is essentially becau

John Forgive what is going to seem like an odd response. I keep wanting people to give me an account in terms of FORCES. So, it is not for me, who is seeking advice on an explanation, to dictate what SORT of an explanation is satisfactory. However, explanations like the the one you kind

James, Your explanation is in terms of the arrangement of the parts... arrangement and connection, if you will. Am I correct? Would you characterize that explanation as a reductive one? This is not a trick question. I genuinely want to know. And should one speak of downward causation h

Nick, Since you are looking for emergence, you don't expect to get a complete explanation of the strength of a triangle in terms of the strength of its parts. Part of the strength of the triangle has to do with how the parts are structured with respect to each other. I suspect that no matter how a

Nick - But surely we cannot reduce the strength of a triangle to the strength of its parts because the strength of a triangle depends on the ARRANGEMENT of those parts. And arrangement is not a property of any of the parts. after my missive on Tolerancing and my claim that "Emergence" requires

I have to admit, I've just reached the limit of my competence. I don't know what it means for an explanation to be reductive. I'll have to go read something about that--my lack of formal education is exposed. A triangle (made of parts) is the name for a particular arrangement of parts. If you arra
