In the first part of this book, there is a historical overview of the views of ancient Greek philosophers, as well as those of modern philosophers (17th - 19th century) on the moral perspective of animals.
In the second part, all theories of ethical treatment of non-human animals are developed, whether they are philosophical or political.
In the third and final part, an effort is made to demonstrate that evolutionary line that connects us with other animals and a political direction is proposed for the contemporary vegan movement.
Excerpt from the book: "The more we collectively struggle, with understanding and faith in our vision, the sooner we will achieve the liberation of both human and non-human animals. It is not enough for each of us to fight alone and for ourselves, merely changing our personal lifestyle. We need to mobilize those around us, using knowledge, arguments, and emotional appeal as our tools, until we achieve the liberation of all animals used by humans, whether they are in farms, laboratories, circuses, or zoos."
