Open, Closed, and Empty Individualism are  philosophical positions concerning the nature of  

personal identity over time, particularly how we  consider the existence and persistence of "self."

Closed Individualism posits  that individuals are distinct  

and separable entities that persist over time.

This view is the most common intuition  about personal identity: that each person  

is a separate individual with a unique and  continuous identity from birth to death.

Open Individualism argues that there is only one  subject of experience, one "I," who is everyone.

According to this view, the boundaries  between individuals are illusory,  

and the consciousness experiencing life through  

one person is the same consciousness  experiencing life through all others.

This philosophy transcends traditional  notions of personal identity,  

suggesting a universal connectedness.

Empty Individualism takes a different approach,  asserting that the self is an illusion and there  

is no real persistence of identity over  time, even within a single person's life.

From moment to moment, there is  no enduring self that continues  

from the past through to the future.  Each moment is its own experience,  

with no actual "individual" that  persists across these moments.
