No individual mind can exist without a framework consisting of cultural components. There is no such thing in reality. Cultures change over time and across space. It is probably helpful to our understanding to say that, at some point in time, one culture has evolved into a different culture. It is a current cultural convention, a rule, that we think of action as originated from individual minds located in individual bodies.
Some current commentators say that the present typical state of consciousness is a trance state.
And each of you for helping me. At least for me they are unthought until I think them. I can imagine the shock to the individual mind on standing up on an African plain and being able to think of one's temporary presence on earth and of death being an event that brings to an end one's earthly existence. I believe the individual mind extends as far into the past as human consciousness does - at least a quarter of a million years or more. I also believe that, from the very beginning, we have struggled with them because we need to also act as individuals to survive.
