Beatings occurred on the slightest provocation, sometimes for no reason at all.
[…] At such a moment it is not the physical pain which hurts the most (and this applies to adults as much as to punished children); it is the mental agony caused by the injustice, the unreasonableness of it all.
[…] The most painful part of beatings is the insult which they imply.
— Viktor E. Frankl, Man’s Search for Meaning, 1946, Beacon Press (2006 edition), p. 36-37
