The imagination of a boy is healthy, and the mature imagination of a man is healthy; but there is a space of life between, in which the soul is in a ferment, the character undecided, the way of life uncertain, the ambition thick-sighted: thence proceeds mawkishness.
John KeatsO fret not after knowledge - I have none, and yet my song comes native with the warmth. O fret not after knowledge - I have none, and yet the Evening listens.
John Keats
