Quote by Friedrich Nietzsche
Madness is rare in individuals - but in groups, parties, nations, and ages it is the rule.
Summary
This quote suggests that while madness, or irrational thinking and behavior, is uncommon or rare in individual people, it becomes prevalent or customary when these individuals form groups, parties, nations, or live in specific time periods. It implies that collective thinking can sometimes lead to collective madness, where the beliefs and actions of a group or society may not make logical sense when examined from an individual perspective. This quote reflects the potential for irrationality and insanity to emerge on a larger scale and highlights the influence of collective behavior on the prevalence of madness.
