Wittgenstein's Mistress is a novel unlike anything David Markson - or anyone else - has ever written before. It is the story of a woman who is convinced, and, astonishingly, will ultimately convince the reader as well, that she is the only person left on earth. Presumably she is mad. And yet so appealing is her character, and so witty and seductive her narrative voice, that we will follow her hypnotically as she unloads the intellectual baggage of a lifetime in a series of irreverent meditations on everything and everybody from Brahms to sex to Heidegger to Helen of Troy.

And as she contemplates aspects of the troubled past which have brought her to her present state, so too will her drama become one of the few certifiably original fictions of our time.

What if everything in the world were a misunderstanding, what if laughter were really tears?

Either/Or is the earliest of the major works of Søren Kierkegaard, one of the most startlingly original thinkers and writers of the nineteenth century, and the first which he wrote under a pseudonym, as he would for his greatest philosophical writings.

Adopting the viewpoints of two distinct figures with radically different beliefs—the aesthetic young man of Part One, called simply 'A', and the ethical Judge Vilhelm of the second section—Kierkegaard reflects upon the search for a meaningful existence. He contemplates subjects as diverse as Mozart, drama, boredom, and, in the famous Seducer's Diary, the cynical seduction and ultimate rejection of a young, beautiful woman.

A masterpiece of duality, Either/Or is an exploration of the conflict between the aesthetic and the ethical—both meditating ironically and seductively upon Epicurean pleasures, and eloquently expounding the noble virtues of a morally upstanding life.
