The Freudian concept of reliance has been widely discussed. From reliance o
f the drive on the biological, that is, on a self-conservation function, to
reliance on the object, opinions are divided. Just as the concept of hospi
talism described by Spitz taught us the essential role of the object, one o
f the merits of these babies is to recall its importance, but also to demon
strate its insufficiency. It seems futile to attempt to trace a dividing li
ne.
This reflection is uniquely centered on the biological role concerning reli
ance and opens a path of questioning as to the validity of the Freudian des
cription which must demonstrate itself in double reliance, that is, in the
narrow articulation of respiratory and feeding functions, which, in the nor
mal, habitual case, both serve as a support for the oral sexual drive. The
cathexis of differentiated erogenous zones, the respiratory-digestive tract
s, is realized beginning with a common erogenous zone : the buccal cavity.
