* The cyclical nature of life: The poem's structure itself is a key indicator. It depicts life as a series of stages, each with its own unique characteristics and challenges. This cyclical view suggests a wisdom about the inevitability of change and the interconnectedness of all life's phases.
* Acceptance of impermanence: Each age is presented with its own set of weaknesses and strengths. The infant's "mewling and puking," the lover's "sighs and groans," the soldier's "bearded like the pard," the justice's "round belly," the "lean and slipper'd pantaloon," and finally the "second childishness" are all presented as inevitable, highlighting the transient nature of life and the wisdom of accepting its impermanence.
* Humorous detachment: The poem's use of humor, particularly in describing the ridiculousness of some stages, points to a certain detachment from the world's woes. This detachment implies a wisdom that recognizes the fleeting nature of these struggles and encourages a lighter perspective.
* The final stage: The poem ends with the image of the "second childishness" - a return to a state of helplessness and dependence. This final stage suggests a wisdom that comes from experiencing life in its entirety, acknowledging its limitations and accepting the cycle of life and death.
* A sense of perspective: The poem's tone is overall one of contemplation and observation. It doesn't judge any stage, but rather presents them all with a sense of objectivity and understanding. This perspective offers a deeper understanding of the human condition, ultimately reflecting a kind of wisdom gained through experience.
In conclusion, while "Seven Ages of Man" doesn't explicitly preach wisdom, it offers a powerful depiction of the human journey and its inherent wisdom. Through its cyclical structure, acceptance of impermanence, humorous detachment, and contemplative tone, the poem invites us to recognize the richness and complexity of life, ultimately finding meaning in its inevitable flow.
