A short overview of results stemming from infant research will serve a
s a starting point for the following reflections. 1.) Parental fantasi
es about their children are a powerful conducive or detrimental - deve
lopmental force. The capacity for symbolisation as it expresses itself
in fantasies is (therefore) the ''ultimate'' specifically human found
ation for neurosis or healthy development. 2.) The affects of the infa
nt are of short duration and situatively variable. They gain durabilit
y only later through linkage with fantasies. Aggression is not a probl
em due to its being a drive but because of its propensity for derailme
nt. This occurs when aggression, being in itself an adaptive dispositi
on, becomes connected to destructive fantasies. 3.) An interactional r
evision of the concept of projective identification will be put forwar
d. 4.) The author argues for an interactional supplementation of the t
heory of neurosis which has hitherto primarily focussed on the analysi
s of intrapsychic mechanisms. 5.) Observed interactions between depres
sive parents and their infants support the clinically gained suppositi
ons regarding the genesis of depressive disorders. Furthermore it info
rms of the diversity of modalities serving to express and communicate
states of mind.
