Which thinker is often credited with the idea of 'the golden mean'?

The concept of 'the golden mean' is most closely associated with Aristotle. He introduced this idea as part of his ethical philosophy, which emphasizes moderation and the balance between extremes in behavior and actions. According to Aristotle, virtue lies between two vices: one of excess and one of deficiency. For example, courage is a virtue that lies between the extremes of recklessness (excess) and cowardice (deficiency). This idea is foundational to his ethics, which promotes the notion that living a virtuous life involves finding a harmonious middle ground. Through this understanding of the golden mean, Aristotle sought to guide individuals in achieving moral excellence and a fulfilling life.
