Like Freud's, Winnicott's writing displays an enormous interest in wor
ds, in their histories as well as their current usage. The author disc
usses his use of two words, 'capacity' and 'belief', combined in the p
hrase 'capacity to believe'. What Winnicott has to say about this capa
city sheds light on the nature of both religious and cultural experien
ce generally. The paper's argument has two strands that are woven toge
ther throughout. The first is Winnicott's concern for words and how a
knowledge of their roots can enrich their current meaning. The second
is his concern for the nature of belief, the 'capacity to believe', an
d his conviction that in exploring this capacity psychoanalysis might
have something to teach religion. These concerns are interrelated in a
number of ways in Winnicott's writing and are ultimately connected wi
th his notion of a 'cultural field', a place to grow, where 'inventive
ness', even verbal inventiveness, is 'just one more example... of the
interplay between separateness and union', that is the separateness of
individual language users but also their union through the language t
hey share.
