This quote suggests that our tendency towards aggression is the most significant barrier to achieving a civilized society. In essence, it implies that our innate aggressive impulses prevent us from living harmoniously, as they cause conflict and destruction. Civilization, in this context, refers to a state of social development and organization considered to be most advanced, characterized by a complex cultural and political order, such as respect for the rule of law, social harmony, and mutual respect.

Freud’s idea is based on the belief that humans have an inherent aggressive drive, which, if left unchecked, can lead to hostility and violence. This aggression, he suggests, is the antithesis of civilization, as it disrupts social order, creates conflict, and prevents progress. In a civilized society, these aggressive impulses must be controlled or sublimated into more socially acceptable behaviors to maintain order and harmony.

Applying this idea to today’s world, we can see that aggression, whether in the form of war, crime, or social and political discord, continues to be a significant impediment to civilization. For instance, ongoing conflicts and wars in various parts of the world disrupt social order, cause destruction, and prevent progress, thereby serving as a hindrance to civilization.

On a personal development level, this idea suggests that individuals must learn to manage their aggressive impulses to become more civilized. This can be achieved through various means, such as practicing self-control, developing empathy, and learning conflict resolution skills. By doing so, individuals can contribute to a more civilized society by reducing conflict and promoting harmony.

Ultimately, Freud’s quote serves as a reminder of the importance of controlling our aggressive impulses, both individually and collectively, to achieve a more civilized society. It underscores the need for emotional intelligence, empathy, and peace-building efforts in our quest for civilization.
