From Jean-Paul Sartre's point of view, our human need for belonging is the fundamental driving force behind shame, and what gives it its ontological status.
Because of shame, I no longer exist in a state of transcendent consciousness, but am now self-conscious and reflexively self-aware. Sartre writes: ‘‘Thus the Other has not only revealed to me what I was; he has established me in a new type of being … I need the Other in order to realize to realize fully all the structures of my being’
Sartre employs the account of ‘the look,’ and concomitantly shame, as a multilayered metaphor. In some sense, he is being literal: sometimes I do need the other to judge me before I realize something about myself. In these cases, the seeming temporality of Sartre’s account, where I start as a self-contained transcendent subjectivity, and am transformed into a self-aware relational being, as a result of the objectifying look of the other, makes some sense.
Shame is the feeling of an original fall, not because of the fact that I may have committed this or that particular fault but simply that I have ‘fallen’ into the world in the midst of things and that I need the mediation of the Other in order to be what I am.
Sartre’s reference to an original fall indicates that the subject’s deepest desire is to become ‘‘like God,’’ or a being that is pure transcendence, impervious to the objectification of others.
The body symbolizes our vulnerability, neediness, physical desire and ultimately the lack of control we have over our own mortality. Hence the body, especially when it falls ill or fails us, is a powerful source and site of shame.
In fact, it is because of our ‘‘extreme vulnerability to others (in infancy for all one’s needs and in adulthood for one’s very sense of identity and worth)’’that shame experiences form part of the structure of our subjective and intersubjective being.
Sartre repeatedly asserts: ‘I need the mediation of the Other in order to be what I am’

In Nietzsche point of view about Human need is relates to "meaning".
Nietzsche claims that human beings have acquired a new need—indeed a new condition of existence—not shared with other animals. Meaning is a uniquely human need. Human beings must see their activity and their existence as meaningful because we are reflective creatures. We need to know why we exist and to see a reason for going on living, not just for the sake of self-preservation, but in order for us to thrive. Non-human animals lack a need for meaning. Nietzsche also claims that the need for meaning gradually developed, implying that human beings didn’t always have this need.
