Another step allowing one to realise the n-dimensional psychic reality could be the naming of other elements of psychoanalysis. The Euclidean representational system still furnishes a helping hand towards its realisation, through polyhedral construction. Again, the human sensuous apparatus can cope with representations of polyhedra with six, eight, ten, twelve and even twenty faces. The mind could be represented, albeit imperfectly, by its sensuous bases which also confer a kind of comprehension, by an n-dimension polyhedron whose faces are not equal to each other (Fig. 22).
