Ideas have consequences

Victor Frankl, survivor of Auschwitz, once said:

“The gas chambers of Auschwitz were the ultimate consequence of the theory that man is nothing but the product of heredity and environment…I am absolutely convinced that the gas chambers of Auschwitz, Treblinka, and Maidanek were ultimately prepared not in some ministry or other in Berlin, but rather at the desks and in lecture halls of nihilistic scientists and philosophers." - Can Man Live Without God?, Ravi Zacharias
