Context

“907
But is it probable that probability gives assurance?
Difference between rest and security of conscience. Nothing gives certainty but truth; nothing gives rest but the sincere search for truth.
908
The whole society itself of their casuists cannot give assurance to a conscience in error, and that is why it is important to choose good guides. Thus they will be doubly culpable, both in having followed ways which they should not have followed, and in having listened to teachers to whom they should not have listened.
909
Can it be anything but compliance with the world which makes you find things probable?” source
