 Freud saw inhibited development, fixation, and regression as centrally formative elements in the creation of a neurosis.Arguing that 'the libidinal function goes through a lengthy development', he assumed that 'a development of this kind involves two dangers – first, of "inhibition", and secondly, of "regression" '.Inhibitions produced fixations; and the 'stronger the fixations on its path of development, the more readily will the function evade external difficulties by regressing to the fixations'.
