The ‘proper’ basis for the personal identity of any given human is a hard thing to derive… if you’re limited to the tools of, say, science. Â Science wonderfully (and tragically in the case of murder, hate, discrimination, etc.) describes what humans ‘do’ (human doings), but not what/who humans ‘are’ (human beings).
I’d want to affirm that ‘doing’ (as well as ‘knowing’ and ‘feeling’) is a necessary component of what a human ‘being’ is, but not the whole composition. Â Any identity based on only feelings, actions and intelligence alone is incomplete and leaves out something.
