Introduction:
In the poem "The Lake Isle of Innisfree" by William Butler Yeats, the poet expresses his longing for a simple and peaceful life in nature. Through his words, he upholds several values that are important for a fulfilling and meaningful existence.

Connection with nature:
One of the core values supported by the poet is the deep connection with nature. The speaker yearns to escape the hustle and bustle of urban life and retreat to a serene and idyllic place. He longs for the sounds of nature, such as the lapping of water and the singing of crickets, which can provide solace and inner peace.

Self-sufficiency and simplicity:
Another value the poet supports is self-sufficiency and simplicity. The speaker desires to build a small cabin on the isle, where he can live a self-reliant life. He wishes to grow his own food, such as beans and honey, and engage in simple tasks like fishing and collecting honeycombs. This emphasis on a simple lifestyle suggests a rejection of materialism and a preference for a more sustainable and pared-down existence.

Escaping the pressures of modern life:
The poet also champions the idea of escaping the pressures of modern life. The speaker expresses his weariness with the noise and stress of the city, longing instead for the tranquility and solitude of the isle. By retreating to this imagined place, he seeks respite from the demands and complexities of contemporary society.

Harmony and balance:
The poem also highlights the value of harmony and balance. The speaker yearns for a life where he can find peace and quietude, where his mind can be still and his soul can be at ease. This desire for inner harmony suggests a need for a more balanced and centered way of living, in contrast to the frenetic pace and distractions of modern life.

Conclusion:
Through "The Lake Isle of Innisfree," William Butler Yeats promotes values such as a deep connection with nature, self-sufficiency and simplicity, escaping the pressures of modern life, and seeking harmony and balance. These values serve as a reminder of the importance of finding solace, meaning, and fulfillment in a world that often demands much more.
