Logos in "The Rights of Animals" by Brigid Brophy

In Brigid Brophy's, "The Rights of Animals," Brophy makes exceptional use of logos in constructing her argument that animals are more than mere commodities made for humans, and should be treated as such. Brophy structures her argument around the assumptions and perceptions of most (animal consuming) humans in her society. She uses simple, syllogistic, and rational explanations for why she believes that it is wrong for humans to 'use' animals. Additionally (and one might call this ethos, but I think it also falls under the category of logic), Brophy addresses the assumptions that most members of her society make about her based on her arguments and explains why those assumptions and preconceptions are irrational and therefore irrelevant. She also points out several logical fallacies typically used by her opponents, such as the ad populum fallacy and the false dilemma fallacy. In summary, the effectiveness of Brophy's article can be attributed to her appeal to logos on the issue of animal rights.
