I think any finite activity requires some sort of embodiment, and consequently that anything like the practically engaged spirits Berkeley talks about must also have some embodiment. On the other hand, the various strands of activity from which our eventual essence is precipitated over time — commitments, thoughts, feelings — are not strictly tied to single individuals, but are capable of being shared or spread between individuals.
Most notably, this often happens with parents and their children, but it also applies whenever someone significantly influences the commitments, thoughts, and feelings of someone else. I feel very strongly that I partially embody the essence and characters of both my late parents — who they were as human beings — and I see the same in my two sisters. Aristotle suggests that this concrete transference of embodied essence from parents to children is a kind of immortality that goes beyond the eternal virtual persistence of our essence itself.
Our commitments, thoughts, and feelings are not mere accidents, but rather comprise the activity that constitutes our essence. I put commitments first, because they are the least ephemeral. In mentioning commitments I mean above all the real, effective, enduring commitments embodied in what we do and how we act.
