Hannah Arendt was a philosopher accustomed to using metaphors. Among other things, she advocated for their use in philosophical reflection in her Journal of Thoughts.[1] In The Origins of Totalitarianism, Arendt explored the question of totalitarianism – how these types of regimes form, evolve, exist, and perish.[2] She also examined the differences between totalitarianism and other forms of political systems, such as autocratic regimes.[2][3][4]
In this context, Arendt uses the metaphor of the onion to represent the structure of totalitarian systems.[2][5][6] This metaphor illustrates an organized structure centered around a central point, the leader of the totalitarian system.[2] She contrasts this structure with other types, such as the pyramid-like structures of autocracy or tyranny.[7][8] This depiction reveals that totalitarianism evolves in "waves", spreading through different layers of society.[9] The closer one is to the center, the more radicalized they are, whereas those closer to the periphery are less radicalized.[7] With this example, Arendt also exposes the dual nature of totalitarian organizations, possessing two faces—one presented to the external world, appearing normal, and another turned inward, radicalized.[7]
The metaphor is described by researchers like Sophie Schulze as follows:[10]
For Arendt, the onion structure designates two distinct things: one, that power diffuses from the center to the periphery (centrifugal movement); the other, that each circle maintains itself through the balance between two opposing forces.
This structure also enables totalitarian regimes to absorb shocks from the external reality of the system.[11] Each layer of the onion absorbs a bit of the shockwave, ultimately rendering the contact with external reality harmless. This occurs despite the contradictions with the practical and scientific lies propagated by totalitarian regimes.[11][12]
The use of the metaphor was deemed relevant when discussing, among other things, the USSR under Stalin, Nazi Germany, and Imperial Japan.[13] The notion that this structure helps totalitarian regimes avoid 'external reality shocks' is also considered an important concept in psychology.[11]
