In this important book, Lesley Jeffries introduces a phenomenon which has not been given the attention it deserves - the contextual construction of oppositional meaning. These are opposites not recognisable as such out of context but that are clearly set up this way in the text concerned.
The significance of oppositional meaning is well-known, and has been discussed by scholars for millennia, from Philosophy to Politics. But the main emphasis has always been on the conventional opposite: the opposite recognised by lexical semantics.

Language items: It is the opposite of good.
Topics and vocabulary: Words and their opposites.

Spirits Unseen~The Representation of Subtle Bodies in Early Modern European Culture

Spirits – airy, volatile ‘subtle bodies – occupied a central place in early modern European culture. At the edge of the visible and perceptible, spiritus could signify a broad variety of subtle substances, both natural and divine: the vapours moving inside the body, the elements of air and fire, angels, demons and spectres, the Holy Spirit and the human soul. Spirits functioned as intermediaries between two opposite worlds with continually shifting borders.

Steppenwolf

Harry Haller is a sad and lonely figure, a reclusive intellectual for whom life holds no joy. He struggles to reconcile the wild primeval wolf and the rational man within himself without surrendering to the bourgeois values he despises. His life changes dramatically when he meets a woman who is his opposite, the carefree and elusive Hermine. The tale of the Steppenwolf culminates in the surreal Magic Theater—For Madmen Only!

The Unadulterated Cat

The Unadulterated Cat by Terry Pratchett is a book written to promote what Pratchett terms the 'Real Cat', a cat who urinates in the flowerbeds, rips up the furniture, and eats frogs, mice and sundry other small animals. The opposite of the Real Cat is the 'Fizzy Keg Cat', a well-behaved and bland kind, as seen on cat food advertisements.
