All that is necessary for evil to succeed is that good men do nothing. - Edmund Burke.

When the Nazis came for the communists,
I remained silent;
I was not a communist.

Then they locked up the social democrats,
I remained silent;
I was not a social democrat.

Then they came for the trade unionists,
I did not speak out;
I was not a trade unionist.

Then they came for the Jews,
I did not speak out;
I was not a Jew.

When they came for me,
there was no one left to speak out for me!

--Pastor Martin Niemöller (1892–1984) about the inactivity of German Intellectuals followingthe Nazi rise to power and the purging of their chosen targets, group after group.
