Analysis of The Fugitive Ideal

As some most pure and noble face,
Seen in the thronged and hurrying street,
Sheds o'er the world a sudden grace,
A flying odour sweet,
Then, passing, leaves the cheated sense
Baulked with a phantom excellence;

So, on our soul the visions rise
Of that fair life we never led:
They flash a splendour past our eyes,
We start, and they are fled:
They pass, and leave us with blank gaze,
Resigned to our ignoble days.
