"In individuals, insanity is rare; but in groups, parties, nations and epochs, it is the rule"

This quote by Friedrich Nietzsche suggests that while individual individuals may be reasonably sane, when they come together in groups, celebrations, nations, or dates, they end up being more prone to insanity. This could be interpreted as a warning versus the power of groupthink, and how it can result in unreasonable and harmful habits. It might likewise be seen as a commentary on the propensity of people to end up being more extreme in their beliefs when they are part of a group. Nietzsche's quote suggests that when people come together in large numbers, they are most likely to act in manner ins which are not in their own benefits. This could be viewed as a cautionary suggestion to be knowledgeable about the power of group dynamics and to be conscious of the capacity for illogical habits when individuals come together in great deals.
