Meaning: This quote is attributed to the Roman Emperor Marcus Aurelius, who was also known for his philosophical writings. The quote speaks to the idea of controlling one's anger by considering the brevity of human life. It suggests that when one feels an intense or excessive anger, they should remind themselves of the fleeting nature of life.

Marcus Aurelius, who reigned from 161 to 180 AD, is perhaps best known for his work "Meditations," a series of personal writings and reflections on Stoic philosophy. Stoicism emphasizes the importance of self-control, rationality, and the acceptance of things beyond our control. The quote in question aligns with Stoic principles by encouraging individuals to take a broader perspective on their emotions, particularly anger, and to consider the transient nature of human existence.

The first part of the quote, "When thou art above measure angry," acknowledges the intensity of anger. It suggests that there are times when anger can become overwhelming and all-consuming. This acknowledgment is important because it recognizes the powerful and sometimes uncontrollable nature of anger, which is a common human experience.

The second part of the quote, "bethink thee how momentary is man's life," offers a solution for dealing with excessive anger. It encourages individuals to reflect on the fleeting nature of human life. This reflection may serve as a reminder that the things which provoke our anger are often inconsequential in the grand scheme of our existence. It invites individuals to consider whether it is worth expending their limited time and energy on feelings of anger.

The use of the term "momentary" is significant, as it underscores the brevity and transience of human life. This word choice emphasizes the fleeting nature of our time on earth and encourages individuals to consider whether their anger is a worthwhile investment of this precious and limited resource.

The attribution of the quote to Marcus Aurelius, who was not only a renowned emperor but also a philosopher, adds weight to the message. It suggests that these words were spoken or written by a figure who faced the complexities of human emotion and the challenges of leadership. As such, the quote carries a sense of wisdom and experience, reinforcing the idea that it is valuable guidance for managing one's emotions.

In summary, the quote encourages individuals to confront their intense anger by contemplating the impermanence of human life. By doing so, it aligns with the Stoic principles of self-control and perspective, offering a philosophical approach to managing emotions. The attribution to Marcus Aurelius adds historical and philosophical significance to the quote, lending it credibility and depth. Ultimately, this quote serves as a timeless reminder to consider the bigger picture in moments of intense anger.
