Philosophers spend a lot of time (too much?) debating identity. I grow impatient with such things.
Yet, it is true that there is something slippery about the term. Take my own case. I am Victor Storiguard when I talk about transhumanism. I am other people, with other names, with I write about other things.
How much more complicated will "identity" be when we can genuinely occupy other bodies, have multiple bodies, and be multiple people.
