This article applies a two-axis model of human development to the prob
lem of suicide trajectory. The two-axis approach represents a fundamen
tal shift in the way Eriksonian stages are viewed. Typical interpretat
ions of Erikson suggest healthy development is achieved by resolving e
ach stage crisis horizontally in favor of the syntonic as opposed to t
he dystonic ego quality. A two-axis view proposes that an organism beg
ins each stage at the negative or dystonic position in reaction to the
stage-initiating life event and must move ahead vertically to achieve
the positive syntonic quality and the attaining of a stage-specific s
yntonic equilibrium. We are suggesting that successful development inv
olves not the avoidance of the negative or dystonic ego qualities at e
ach stage but the very plunging into each of them as the natural seque
la of the preceding life event. Successful development involves workin
g through a stage vertically to attain the respective stage-specific p
ositive or syntonic ego position, followed by forward regression to th
e next advanced stage. The logic of this developmental axis is simply
that the loosening of one's defenses (i.e., greater permeability of wa
lls) should occur in conjunction with the strengthening of one's ego (
i.e., greater definition of boundaries). Incongruent resolution of the
individuation-attachment dilemma results in ''enmeshment'' (attachmen
t to the external world without individuation), or in ''disengagement'
' (remaining detached even after becoming sufficiently individuated).
Extreme distress can result from the attempt to simultaneously apply e
nmeshed and disengaged styles to cope with the overwhelming challenges
of the new life stage, creating a potentially suicidal level of stres
s.
