The author begins by noting that the heuristic value of the concept of bise
xuality can be explored in two directions, involving respectively its role
in psychopathology and in the development of creativity and thought. The au
thor concentrates on the first of these aspects, which entails a reconsider
ation of the 'phallic question'. The status of femininity is investigated o
n the basis of Freud's and Winnicott's theories of bisexuality and the auth
or here finds an explanation for the reputation of femininity and for the '
phallic question' thereby implied, which represents the underlying bedrock
resulting in interminable analyses. An important element in this rejection
is stated to be the maternal aspect of femininity. Particularly reference i
s made to the somatic roots of phallic defences and to their effects on tho
ught and symbolisation. Some brief clinical examples al e presented to sugg
est that the bedrock may be due to the distorted use of sensoriality and of
the el otogenic zones. The author contends that the anal zone plays a cruc
ial part in the manifestations of bisexuality and contrasts phallic logic w
ith the logic of triangulation. Numerous literature references and clinical
examples support and illustrate her arguments throughout. The author ends
with a discussion of the implications of bisexuality for thought and knowle
dge.
