“The only thing necessary for evil to triumph is for good men to do nothing.”
This quote is usually attributed to Edmond Burke, though I found some discussion online as to whether or not he really said that. Burke was an Irish political philosopher who lived in the 1700’s and is regarded as the father of modern conservatism. It’s a quote which certainly heightens ones’ sense of responsibility. You could apply it to everything from your country’s politics to everyday life. It removes the excuse of not getting involved in “somebody else’s business” – because it is our business if we see injustice around us.
