The Coming of Wisdom with Time

Of course the first thing I noticed about this poem was the length. The poem is 4 lines long with an average of 8 words per line. Its short, sweet, and to the point. Kind of the way Yeats describes the coming of wisdom throughout the poem. The other thing I noticed was the fact that the first word of the poem is not capitalized but the second, third, and fourth lines have the first word capitalized. I feel like there is a significance to this but I'm not completely sure. Maybe it symbolizes the coming of wisdom like Yeats describes in the poem.

The first line, "through leaves are many, the root is one...," gives a very image rich idea of what Yeats views was wisdom. The leaves represents the countless experiences, memories, and adventures that people experience through life. The "root is one" represents the person in the end of all the experiences. Yeats then uses the last three lines to make a sort of metaphor to the youthful days and the older days.
"Through all the lying days of my youth
I swayed my leaves and flowers in the sun;
Now I may wither into the truth."
Yeats is saying that now since he has experienced all of this, he can be done. The last line "Now I may wither into the truth," seems a little more harsh then the rest of the poem.
