I have focused on this theme before, but I believe it is always important.
“The only thing necessary for the triumph of evil is for good men to do nothing.” Edmund Burke
While today, we would say people instead of men, the importance of the message remains. When evil or the potential for it exists, it must be opposed.
“The world is a dangerous place to live; not because of the people who are evil, but because of the people who don’t do anything about it.” Albert Einstein
Both men from very different times and different political and social backgrounds give a moral imperative to people to stand up to evil, that it cannot and should not be ignored.
