The dictum that we are affected only as we believe is open to grave doubt. We are often thrown into a state of trepidation simply through the power of the imagination. We are wise after the event, like Partridge at the play:

"No, no, sir; ghosts don't appear in such dresses as that neither… And if it was really a ghost, it could do one no harm at such a distance, and in so much company; and yet, if I was frightened, I am not the only person."[6]

The supernatural which persisted always in legends handed down from one generation to another on the lips of living people, had not lost its power to thrill and alarm, and gradually worked its way back into literature. Although Gray and Collins do not venture far beyond the bounds of the natural, they were in sympathy with the popular feelings of superstitious terror, and realised how effective they would be in poetry.

Collins, in his Ode on the Superstitions of the Scottish
Highlands
, adjures Home, the author of Douglas, to sing:

"how, framing hideous spells,
In Sky's lone isle, the gifted wizard-seer
Lodged in the wintry cave with Fate's fell spear
Or in the depths of Uist's dark forests dwells,
How they whose sight such dreary dreams engross
With their own vision oft astonished droop
When o'er the wintry strath or quaggy moss
They see the gliding ghosts unbodied troop."

Burns, in the foreword to Halloween (1785), writes in the "enlightened" spirit of the eighteenth century, but in the poem itself throws himself whole-heartedly into the hopes and fears that agitate the lovers. He owed much to an old woman who lived in his home in infancy:

"She had … the largest collection in the country of tales and songs concerning devils, ghosts, fairies, brownies, witches, warlocks, spunkies, kelpies, elf-candles, dead-lights, wraiths, apparitions, cantraips, giants, enchanted towers, dragons and other trumpery. This cultivated the latent seeds of poetry, but had so strong an effect on my imagination, that to this hour, in my nocturnal rambles, I sometimes keep a sharp look-out in suspicious places; it often takes an effort of philosophy to shake off these idle terrors."[7]

Tam o' Shanter, written for Captain Grose, was perhaps based on a Scottish legend, learnt at the inglenook in childhood, from this old wife, or perhaps

"By some auld houlet-haunted biggin
Or kirk deserted by its riggin,"

from Captain Grose himself, who made to quake:
