Scientific knowledge versus spiritual knowledge

[Angrboda]

A child perhaps hasn't proven to itself rationally that it has value, perpetual identity, worth, praise, etc, but it can believe in these things and be justified in doing so.

A child can be justified in believing in these things without it rising to the level of knowledge, nor with it being true. I find it odd that you use the example of a child, as children are particularly susceptible to mistaking insufficient justification for belief with knowledge.
