Vladimir Nabokov was a self-described memorist. From a very early age he knew that preserving the past was not only important, but making it central to one's life was the only validation to existence. The present is but milliseconds, he said, and the future only a set of random possibilities; but the past is real, it has been lived, it has been an expression of personality, character, and desire. What more to life is there?
Nabokov said that the past and only the past defines human existence. The present, Nabokov is nothing more than a moment of existence before becoming the past. The Higgs boson once produced has a lifetime of less than one sextillionth of a second; and this is slow compared to the passage of the present to the past. The future is only a speculative time of possibilities and impossible dreams.
The more one remembers the past, said Nabokov, lives it through constant recollection, and curates it as a personal, existential treasure, the more one’s life has substance and meaning. Nabokov developed techniques to fix events in his memory and devised ways to recall them from his mental archives and replay them like a movie. The more he could remember, he said, the more complete he was as a human being.

However one chooses to define the present, it quickly becomes the past, archived in our memory, and without attention can disappear. If we cannot remember the beach at Deauville - the umbrellas, the silhouette of the cliffs of Dover on the English side of the Channel, the seagulls, the chill, and the dresses of young girls – then it never happened. Even if the events of that day had subliminal effects – our preference for colored dresses or our dislike of the chill – if we cannot remember them, they have lost their meaning, integrity, and substance.
Nabokov’s Speak, Memory is an autobiography which was written not as a historical record of the author’s life, but as a pastiche of those memories which define him. There was no reason to order them chronologically, to link them to future events citing cause and effect, only to celebrate them for what they were – integral and indispensable parts of him.

'You can't repeat the past', Nick Carroway says to Gatsby in Fitzgerald's The Great Gatsby.
'Can't repeat the past?', Gatsby replies, incredulously. 'Of course you can'.
Gatsby had loved Daisy for four years - the long interlude of the war before which she promised to marry him, during which she became frustrated with waiting and married Tom Buchanan, and after which she once again professed her love for her charming prince, home from the wars.
During his time home from France and before he once again met Daisy, he built his mansion across the water from her home and the blinking green light on her dock was a fetish, a call sign, a signal, a marker, a beacon. It meant not only that the present Daisy was there real and indefinably beautiful as ever, but that the past was there, unchanged and ready to be recovered and relived.

Nick reflects on Gatsby who embodied all the things he detested in a man but who represented the one quality almost never found in any human being - hope, a sense of possibility, encounter, and irrefutable love. At the moment when Nick confronted Gatsby with the truth - that love, like every other youthful ambition - has its place in fond memory, but can never be recreated because it was never, nor ever could be, real - Gatsby is incredulous.
Fitzgerald often writes about young, irreplaceable love - a love that persists without logic, that retains its hold regardless of its fantasy. It is to be held in trust, remembered, never loosened. 'There are many kinds of love in the world', he writes in his short story The Sensible Thing, but never the same love twice. In Winter Dreams he writes of a young man who can never forget or move on from his first love, one so romantically cast - a summer night, moonlight, a starlit sky - that the experience even more than the girl lock him forever within the past.
In Lolita Nabokov writes of the same, almost mystical qualities of young love and how it is not only indelible but pursuant. Humbert Humbert's adolescent love for a girl who died confines him within his memories of her. He compares every woman to her, but no woman can ever compare; until the past is repeated and he meets Lolita - not a grown woman who reminds him of his young love's innocence and simple beauty, but a girl exactly like the one he loved. He has done the impossible - he has recreated the past.

A man I knew fell in love with a Swedish woman and spent a long midsummer's night with her in Stockholm, an idyll he recalled to friends, a deeply emotionally endowed affair that had stayed with him long after the affair had ended. For months after she left for Eritrea, she was always on his mind. 'I reset the reel', he said, 'and replayed the film over and over again'.
Nabokov developed a way of fixing in his memory those events, people, and places that he knew would be important to him in the future; and he replayed them again and again to assure that they would never be given to interpretation, editing, or revision.
The man I knew tried to do the same. He remembered the smell of tobacco in the taxi that took him from the airport to the hotel where Inger would meet him, the arrangement of flowers in the stone planters on the steps up to the hotel, the sound and chatter of the lobby, the chandelier in the ballroom, the music of a string quartet; and every day after he left Stockholm he rewound the reel and played it again - remembering the flowers, the tobacco, the lobby, the Victorian elevator, the smell of the long corridors.
The fact that the memories faded, intruded upon and confused, was no surprise. Even Nabokov's assiduousness failed him as the present and anticipation of the future intruded on the past and made it more and more indistinguishable from every other bit of his history.
Humbert Humbert and Jay Gatsby carried their first loves with them until they were requited - in Gatsby's case his reunion with Daisy, the rekindling of their love; in Humbert's case his discovery of Lolita, the incarnation of his his childhood love, their passionate affair.
Lolita was called by one critic literature's most compelling love story; and despite the expected criticism from those who saw the book as nothing more than romantic pedophilia and demanded its censure and removal, he held to his view. A love that had its origins in the most beautifully pure and responsive adolescence, a love which not only was never forgotten but became an emotional point de repere and then found its regeneration and rediscovery in Delores Haze could only be described as the way love should be - irresistible, unavoidable, and beyond censure and expectation.
Gatsby could never, would never, forget Daisy for all her deceit and selfishness. He had been won over not just by Daisy but by the affair of young love, destined for everyone to be the love of one's life. He could never see beyond that.
Sam Dodsworth, the main character in Sinclair Lewis's novel of the same name, was no different. He was besotted by the young, vivacious Fran and despite her deliberate neglect, utter emotional depravity, and selfish ambitions, he cannot leave her. She takes lovers, abuses him, callously turns him away, and leads her gay, empty, ambitious life without him; and yet he confesses to himself and to others that he loves her and cannot do without her.

He cannot see what she has become or what she is becoming. His love for her, conditioned by first love and its romantic setting; and responding to some indefinable internal need, was in fact unconditional.
When men get divorced, widowed, or left behind, they will always seek out their old girlfriends, especially their first loves. Perhaps, just maybe, the spark that they had when teenagers and young adults can be restruck. Love especially first love has its indelibility. It has not yet been conditioned by necessity, obligation, or duty; and therefore can still exist even after decades of hard use.
Thomas Wolfe wrote You Can't Go Home Again, described by one critic as 'a sweeping, emotionally charged journey of a writer exiled from his past, traveling across continents to confront truth, disillusionment, and the enduring human need to belong.' The book, harsh in tone, critical, offensive, and dismissive of the past which held him captive, has none of the limning, romantic sense of the past of Gatsby or Lolita; but it deals with the same theme - the absolute hold and importance of the past as a human signifier. Despite the raucous journey through America that Wolfe describes and the many disruptive, demanding, and irresistibly alluring moments of it, he cannot shake the dirt from his roots.

Thousands of romantic novels have been written - romantic fiction for women is one of the industry's most profitable sectors, and the greatest writers have placed love at the center of their fiction, using it as metaphor, dramatic showpiece, popular meme, eternal conundrum - but Lolita and Gatsby stand out because of their rootedness in the past and their understanding that true love is not a matter of happenstance or circumstance, but original.
