"Those who will not learn from history are condemned to repeat it" -- Santayana

More good reading: Tiergartenstrasse 4: T-4 Aktion Nazi Euthanasia Program Also this: Lamarck, Darwin, Haeckel and Nazi eugenics -- "Naziism is applied biology"

Nazi propaganda poster, 1936. It says pretty much what the other one does (and what Hitler said), that the handicapped or biologically unfit are an intolerable burden on the nation and on its treasury.

Let's try that Santayana quotation again, I meant only to paraphrase... Here's a Wikipedia discussion:

    * Progress, far from consisting in change, depends on retentiveness. Those who cannot remember the past are condemned to repeat it.

          o This famous statement has produced many paraphrases and variants:
            Those who cannot learn from history are doomed to repeat it.
            Those who do not remember their past are condemned to repeat their mistakes.
            Those who do not read history are doomed to repeat it.
