Tolkien on Fairy Tales

What's special about Fairy Tales?

Professor JRR Tolkien writes in 'Tree and Leaf':

 Fairy Tales are not moral tales [Bunyan] or animal fables [Aesop] or dreams [Alice] or travellers' tales or allegories [Orwell] or satires [Swift] They have an ancient origin with elements of the 

• mystical [supernatural like religion] 
• magical [through observation of Nature] and 
• a mirror [reflecting the nature of human beings]

Fairy tales often explore what is prohibited; what is behind the locked door? Forbidden love, for instance.A spell is both a story told and a charm with power over people.Fairy tales are not simple yarns that appeal to children, in fact not all children enjoy them. 

Fairy Tales can be a literary genre which explores the depths of space and time, the ability to communicate with other living beings, They are presented and read as 'true'.

 Andrew Lang, a collector and writer of Fairy Tales says they require:

'a willing suspension of disbelief'

Tolkien disagrees, 

  He states that the best Fairy Tales enchant,that is they create a secondary world, with its own rules that draws the reader in.
