"And people are often unable to do anything, imprisoned as they are in I don’t know what kind of terrible, terrible, oh such terrible cage. […] Do you know what makes the prison disappear? Every deep, genuine affection. Being friends, being brothers, loving, that is what opens the prison, with supreme power, by some magic force. Without these one stays dead. But whenever affection is revived, there life revives."
Vincent Van Gogh in a letter to his brother Theo (July 1880)
