the Master is stopped from investigation?
To add some context:
「夫子至是邦也，必聞其政，求之與？抑與之與？」
this is where OP's quote coming from.

求之與？抑與之與？
求之與？ is basically saying "do you seek it yourself(perhaps doing some investigative work) to obtain the information"

抑與之與？
is saying "or you just hear(hear to believe) what other people are saying"
