Houdini

SI 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.
