I think of philosophy cultures in this way. The models offering structural integrity, with rhizomes fostering added supports and extensions, and the bridging, like that of a cantilever, of some synergy that runs through, allowing matters of process to proceed, like a rail line. The waters, something of experimentation, something of the process being explored that can result in the process being channeled. For example, narrative computation resulting in informatic interactivity and likely newer institutional development, as an evolving transitional. This, obviously being metaphorical, is not to be essentializing, nor would this be of summative assessment, but rather, there is always that need for a vision, in relation to mission(s) and objective(s). I think the Firth of Forth Bridge is a good vision. Even in terms of bottom-up and top-down structuring managing balance to establish a process running through, the successful design corresponds.
