quotes from The Problem of Pain

Regarding shame:

"We are told to 'get things out into the open', not for the sake of self-humiliation, but on the grounds that these 'things' are very natural and we need not be ashamed of them. But unless Christianity is wholly false, the perception of ourselves which we have in moments of shame must be the only true one; and even Pagan society has usually recognised 'shamelessness' as the nadir of the soul. ... It is mad work to remove hypocrisy by removing the temptation to hypocrisy: the 'frankness' of people sunk below shame is a very cheap frankness."

Regarding sadness:

"My own idea, for what it is worth, is that all sadness which is not either arising from the repentance of a concrete sin and hastening towards concrete amendment or restitution, or else arising from pity and hastening to active assistance, is simply bad; and I think we all sin by needlessly disobeying the apostolic injuntion to 'rejoice' as much as by anything else."
