"Madness is rare in individuals - but in groups, parties, nations, and ages it is the rule"

This quote by Friedrich Nietzsche suggests that while people might have the ability to keep a level of sanity, when it comes to bigger groups such as celebrations, countries, and ages, insanity is the standard. This might be analyzed as a criticism of the collective mentality of society, and how it can result in unreasonable and destructive habits. Nietzsche's quote suggests that when people come together in a group, they can end up being vulnerable to the impact of the group, and can be driven to act in ways that they would not typically do as an individual. This could be viewed as a warning versus the threats of groupthink, and how it can lead to a loss of specific autonomy and a descent into mayhem.
