Applying Cartesian principles to the vegan question, I am forced by reason to conclude that some chickens' eggs are probably vegan.
I think there are many arguments supporting the conclusion that some eggs can be vegan. Here is one:
Veganism is hard. Eggs make it easier (in terms of both experience and wellbeing). Therefore, by eating *eggs, vegans are more likely to remain vegan. Therefore, by eating *eggs, vegans are increasing the maximum potential suffering reduction of Veganism.
*eggs- for example: the tenth egg taken from a feral chicken's nest, would, in my opinion, be totally cool to eat. Vegan healthy yumminess.
