Think for yourself, question authority.

Well thank you Mongoose - it was left open because it should be left open. It’s for the sake of intellectual “honesty” - not to be deceptive or to trick. If knowledge is, then how knowledge got there is irrelevant to it being knowledge, for the sake of it being knowledge. So you’re right, say the 5 year old is a psychic. Perhaps the child is a genius. Perhaps the physicist made a simple mistake, or miscommunicated something. Perhaps the physicist cheated through college. Perhaps the physicist is a sociopathic liar. Perhaps the child got lucky.

The point of this whole thread is that reason and logic, coupled with your values essentially are the authority, not people.
