Single Idea 16794
[filed under theme 9. Objects / F. Identity among Objects / 3. Relative Identity
]
Full Idea
It makes a great difference to ask concerning Socrates whether he is the same human being or whether he is the same body. For his body, when he is old, cannot be the same it was when he was an infant. …He can, however, be the same human being.
Gist of Idea
As an infant, Socrates was not the same body, but he was the same human being

Book Ref
