Breathing is a physical action, so there isn’t much to debate there. However, even some physical actions—like using the bathroom—can have political or cultural dimensions. For instance, why do you use a toilet instead of a bidet, as is common in parts of Europe or South America? That choice is shaped by cultural and economic factors that influence your behavior.
Because my bathroom is too small to house a bidet.
Also, a bidet and toilet don’t serve the same purpose so your example is a false choice.
> Well, that depends on what you eat. Do you eat meat, or are you vegan?
The choice of what to eat can reflect or engage with political and social systems, but it isn’t a political act. It is a personal act. And “to eat” is also not a political act.
Aristotle said politics is the study of how communities can achieve “the good life” through governance and organization. He said we are political animals (zoon politikon) who naturally form communities, such as the polis (city-state), to achieve common goals and virtue.
The idea that any human action is political cannot be attributed to Aristotle. It is also a silly and amateur assertion — to breathe is not political, to think is not political, to eat is not political, etc.
