Looking back. Looking ahead. 2020-2025

210   SPEECHES | INSTITUTIONS Institutions shared ethical convictions.We must not take them for granted. We must defend them again and again. The memory of the suffering caused by the systematic violation of human dignity can – when it reaches in and touches our souls – renew our resolve to stand up for human dignity today. That is why I am grateful for acts of remembrance like today’s. And that is why I am grateful that we will now hear from Leon Weintraub, who is gracious enough to share his own personal memories. May remembrance of the past help us put humanity first – now and in the future. Thank you for listening! FOOTNOTES 1 Victor Klemperer, LTI.
