Tyranny, Injustice and Self-Determination.

Tyranny is when you abuse your power/authority.
Injustice is the unfair treatment of others.
Self determination is to do what you want without anyone else telling you what to do.

Farmer Jones was tyrannous and abused his power over the animals. He gave them very little food, worked them too hard, and showed injustice to the animals by mistreating them. The animals showed self-determination to overthrow Farmer Jones because they wanted to overthrow for their own reasons and not anyone else's.
