In her 1993 book New Maladies of the Soul philosopher and psychoanalyst Julia Kristeva wrote about how the psychological ailments she found in her patients differed from those uncovered by Freud a hundred years previously. In particular she noted "Today's men and women - who are stress-riden and eager to achieve, to spend money, have fun and die - dispense with the representation of their experience that we call psychic life... We have neither the time nor the space needed to create a soul for ourselves, and the mere hint of such activity seems frivolous and ill-advised." Where Freud had found people with complex entanglements in their psyches, Kristeva discovers people who barely have any interior life at all: their inner worlds are impoverishied and nearly empty.
