On taking a shit

From a thread in The Other Place:

“Suddenly I had to think of him.” Say a picture of him suddenly floated before me. Did I know it was a picture of him, N.? I did not tell myself it was. What did its being of him consist in, then? Perhaps what I later said or did.

(Zettel, 14)

If to know is to hold a justified true belief, then what is the justification here? I know it is a picture of him because I recognise it as such? But that is to say just that I know it is a picture of him because I know it is a picture of him…

And if there is no justification, then do we not know that it is a picture of him?

Now apply this to taking a shit. Can one properly be said to know one needs to shit? What is the justification here?

In my ubiquitous puppy-kicking for fun example, what is the justification for seeing the act as cruel?

Rather, we recognise that it is a picture of him; One recognises that one needs the loo; and one recognises that the puppy-kicking for fun is cruel.

This by way of a partial return to the lost theme in Furthering Philippa Foot.
