In The Psychology of Revolution, Gustave Le Bon says that belief is unconscious and uninfluenced by reason.
The revolution is the work of believers. It is hated by some and praised by others, and is a dogma that is either accepted or rejected as a whole, without the use of logic.
Reason may spark a revolution but can only develop by mystic and emotional elements.
A revolution become a belief, but it often begins because of the suppression of crying abuses or a despotic government, or unpopular state.
Logic can point to the abuses of the government, but to move masses of people, its hopes must be awakened.
