The subjective can be so over-emphasized that the individual’s inner world becomes entirely divorced from reality. In that case we call him mad. On the other hand, as Winnicott points out, the individual can suppress his inner world in such a way that he becomes over-compliant with external reality. If the individual regards the external world merely as something to which he has to adapt, rather than as something in which his subjectivity can find fulfilment, his individuality disappears and his life becomes meaningless or futile.
