The instinctive and the inventive mind are the elaborating forces towards the creation of a work of art.
The schemata governing an artistic thought either represent and derive from the inventive mind or indicate the instinct, and suggest the belief in the close interaction of rational and irrational thinking that generates the 'symbol'.
So we'll go no more a-roving
So late into the night,
Though the heart still be as loving,
And the moon still be as bright.
For the sword outwears its sheath,
And the soul outwears the breast,
And the heart must pause to breathe,
And love itself have rest.
Though the night was made for loving,
And the day returns too soon,
Yet we'll go no more a-roving
By the light of the moon.
