Beware of her fair hair, for she excels All women in the magic of her locks; And when she winds them round a young man's neck, She will not ever set … - Johann Wolfgang von Goethe

The artist may be well advised to keep his work to himself till it is completed, because no one can readily help him or advise him with it...but the scientist is wiser not to withhold a single finding or a single conjecture from publicity.

Nowhere would anyone grant that science and poetry can be united. They forgot that science arose from poetry, and failed to see that a change of times might beneficently reunite the two as friends, at a higher level and to mutual advantage.

Nothing is therefore more dangerous than solitude. Our imagination, forced by its very nature to unfold, nourished by the fantastic visions of poetry, gives shape to a whole order of creatures of which we are the lowliest, and everything around us seems to be more glorious, everyone else more perfect...If, on the other hand, we can make up our minds to go about our daily tasks, resigned to our feelings, and hardships, we often find that, in spite of our meanderings and procrastinations, we have gone farther than quite a few others have gone with their sails unfurled and steering gear functioning.
