Javier Marías said this quote

...and yet the idea is hard to accept, it's so hard to succeed in making something happen, even what's been decided on and planned out, not even the will of a god seems forceful enough to manage it, if our own will is made in its semblance. It may be, rather, that nothing is ever unmixed and the thirst for totality is never quenched, perhaps because it is a false yearning. Nothing is whole or of a single piece, everything is fractured and evenomed, veins of peace run through the body of war and hatred insinuates itself into love and compassion, there is truce amid the quagmire of bullets and a bullet amid the revelries, nothing can bear to be unique or prevail or be dominant and everything needs fissures and cracks, needs it negation at the same time as its existence. And nothing is known with certainty and everything is told figuratively.

~ Javier Marías

Fiction has the ability to show us what we don’t know and what doesn’t happen.

~ Javier Marías

When you don’t know what to believe, when you’re not prepared to play the amateur detective, then you get tired and dismiss the entire business, you let it go, you stop thinking and wash your hands of the truth or of the whole tangled mess—which comes to the same thing. The truth is never clear, it’s always a tangled mess. Even when you get to the bottom of it. But in real life almost no one needs to find the truth or devote himself to investigating anything, that only happens in puerile novels.

~ Javier Marías

Everything becomes a story and ends up drifting about in the same sphere, and then it's hard to differentiate between what really happened and what is pure invention. Everything becomes a narrative and sounds fictitious even if it's true.
