“The faculty of imagination is the great spring of human activity, and the principal source of human improvement. As it delights presenting to the mind scenes and characters more perfect than those which we are acquainted with, it prevents us from ever being completely satisfied with our present condition, or with our past attainments and engages us continually in the pursuit of some untried enjoyment or of some ideal excellence. Destroy this faculty, and the condition of man will become so stationary as that of the brutes”
Dugald Stewart, Scottish Philospher (1753 – 1828)
