"In civilized life, where the happiness and indeed almost the existence of man, depends on the opinion of his fellow men. He is constantly acting a studied part"

Jeremy Collier's quote explores the elaborate characteristics of societal living and the human predisposition to act in action to societal expectations. At its core, the quote recommends that within the confines of civilized society, an individual's joy and, to a level, their existential validation, are greatly dependent on the understandings and judgments of others. This reliance on external recognition prompts individuals to perform particular roles or display habits that align with societal norms and expectations-- a "studied part", as Collier explains.

The expression "civilized life" implies a society that is governed by guidelines, norms, and expectations, recommending a departure from a more natural or base state of presence. In such a structured environment, people often discover themselves in a constant state of self-presentation, where authenticity might be jeopardized in favor of socially acceptable habits. This performance is not simply shallow however is deeply rooted in the social material where social approbation and fear of ostracism determine behavior.

Moreover, the idea that "the joy and indeed nearly the existence of male" rests upon societal viewpoint suggests a profound commentary on human psychology and social behavior. Joy here is intertwined with acceptance, suggesting that the individual's sense of worth and satisfaction is extrinsically encouraged. The existential aspect indicate a deeper philosophical factor to consider of identity and self-regard-- that a person's sense of being is affirmed through the eyes of others.

Collier's wisdom beckons self-questioning on the balance between uniqueness and societal conformity. It presents questions on the cost of social acceptance and challenges one to consider the authenticity of their actions. In essence, it is a reflection on the performative nature of social interactions and a critique of the level to which people might give up individual credibility for the sake of social approval. This quote encourages readers to ponder the implications of living a life determined by external understandings and the potential loss of real self that may accompany such a life.
