This study reconsidered Erikson’s concept of identity from the subjective perspective to enhance self-understanding. Those experiences Erikson labeled as “identity crisis” elicited self-questioning in two instances: at times of memory loss and adolescence. Self-questioning in memory loss was comparable to the loss of personal identity, according to Erikson. Self-questioning during adolescence was comparable to the loss of ego identity. The concept of identity is regarded as “sameness and continuity,” given Erikson’s description of personal identity and ego identity. In this paper, Tatara’s view of “sameness and continuity” was reconsidered from the subjective perspective; leading to the idea that identity is “I am Me as an individual living in society, from birth to death.” Recognizing oneself according to the above definition due to the loss of personal identity proved impossible. Moreover, accepting oneself due to the loss of ego identity also proved to be impossible. This study’s notion of identity could provide ground for Erikson’s concept of identity from the subjective perspective. Further studies could address issues, including the theoretical clarification of existential considerations arising from identity crisis, the theoretical clarification of identity crisis that may shake the grounds of identity through various changes, and developing a theoretical methodology on phenomenological grounds examining the first two endeavors. Key words: identity, sameness, continuity, self-understanding
