The Mystery of Choice by Robert W. Chambers

Where two fair paths, deep flowered
And leaf-embowered,
Creep East and West across a World concealed,
Which shall he take who journeys far afield?
Canst thou then say, “I go,”
Or “I forego”?
What turns thee East or West, as thistles blow?
Is fair more fair than fair—and dost thou know?
