“A man who is good for anything ought not to calculate the chance of living or dying; he ought only to consider whether in doing anything he is doing right or wrong—acting the part of a good man or of a bad.” - The Apology of Socrates by Plato
This short novel, which was written with the intention of being adapted for the theatre (and indeed, there was a movie version), tells a captivating story. It's about the resistance of a small town against an invading force. You can easily substitute "Norway" for the small town and "Germany" for the invading force as needed, and there's no need to go into detail about who the "Leader" is. Steinbeck's tale is filled with such self-righteous passion and vigor that it was secretly printed and circulated by many of the European underground resistance movements during WWII.
“Free men cannot start a war, but once it is started, they can fight on in defeat. Herd men, followers of a leader, cannot do that, and so it is always the herd men who win battles and the free men who win wars.”
