Through clinical experience an effort is made to develop a grid in – knowledge (-K) which was achieved by displacement of column 2 (ψ) to the left of the original. It is asserted that it actively arises as a barrier against the unknown or known and disagreeable. The grid’s heterogeneity is stressed, which becomes more accentuated with the negative dimension. There we face the lower part of the grid (starting from line C) as an inversion of the elements corresponding to the positive grid. However, (–β) elements were created, that are studied by autistic phenomena. Conception of the (–β) elements ruptures or expands Bion’s referential. Transformations into knowledge become important because they will lead the way to transformations in O. A theoretical review became mandatory to develop these ideas about the concepts of – space, -K space, transformations in – K, transformations into hallucinosis, β element and grid according to the parameters of Bion and other authors.
