I know the stars by their names,
⁠Aldebaran, Altair,
And I know the path they take
⁠Up heaven's broad blue stair.

I know the secrets of men
⁠By the look of their eyes,
Their gray thoughts, their strange thoughts
⁠Have made me sad and wise.

But your eyes are dark to me
⁠Though they seem to call and call—
I cannot tell if you love me
⁠Or do not love me at all.

​I know many things,
⁠But the years come and go,
I shall die not knowing
⁠The thing I long to know.
