There is an integration of existing knowledge in the process of constructing new knowledge - as in the natural sciences. This orientation towards integration at lower levels in the building of generalised propositions is typically represented visually as a triangle: A horizontal knowledge structure is 'a series of specialised languages, each with its own specialised modes of interrogation and specialised criteria’ - as in the humanities. A horizontal knowledge structure is represented diagrammatically as a series of discrete strongly bounded and so segmented languages L 1 L 2 L 3 L n
