 Persons are psychic wholes or totalities that must be approached as such. “Every I is unique” (Jedes Ich ist Einmaliges, 1950/2006: 294[343]) with its own “peculiarity” (Eigentümlichkeit), that is incommunicable, even though it also has a “quid” that it shares with other egos. Every human being has “unrepeatable singularity” (2000c: 161[182]). In the human ego, there is a contrast between “ego-life” and “being” (1950/2006 296[345]). The ego is “transparent” (durchsichtig) to itself (1950/2006: 296[345]). For Stein, every person is an ego, but not every ego is a person. A person must be aware of itself and there may be egos (e.g., animal egos) that do not have this self-awareness and transparency. In this regard, to be a person requires a degree of developing self-awareness.
