249 Nowadays, it is easy to be tempted to turn the page, to say that all these things happened long ago and we should look to the future. For God’s sake, no! We can never move forward without remembering the past; we do not progress without an honest and unclouded memory. We need to “keep alive the flame of collective conscience, bearing witness to succeeding generations to the horror of what happened”, because that witness “awakens and preserves the memory of the victims, so that the conscience of humanity may rise up in the face of every desire for dominance and destruction”. The victims themselves – individuals, social groups or nations – need to do so, lest they succumb to the mindset that leads to justifying reprisals and every kind of violence in the name of the great evil endured. For this reason, I think not only of the need to remember the atrocities, but also all those who, amid such great inhumanity and corruption, retained their dignity and, with gestures small or large, chose the part of solidarity, forgiveness and fraternity. To remember goodness is also a healthy thing.
