I have traced in my deliberations the mutual influence of drive and ego development throughout the male child's dyadic and triadic father relatedness as it proceeds within a changing soma and social surround during the first two decades of life. I have made the effort to conceptualize the normal developmental progression in male personality formation with explicit reference to the fate of the boy's dyadic father relationship as well as his negative Oedipus complex in general. These considerations, restricted as they are in scope and gender, assign to the dyadic father complex a nuclear role in neurosogenesis as well as recognize in it an etiological factor in relation to specific forms of psychopathology throughout the male life cycle.
