Full Idea
If one shares my view that justified belief is, at least roughly, well-formed belief, surely animals and young children can have justified beliefs.

A Reaction
I take this to be a key hallmark of the externalist view of knowledge. Personally I think we should tell the animals that they have got true beliefs, but that they aren't bright enough to aspire to 'knowledge'. Be grateful for what you've got.
