Art consists in making others feel what we feel, in freeing them from themselves by offering them our own personality. The true substance of whatever I feel is absolutely incommunicable, and the more profoundly I feel it, the more incommunicable it is. In order to convey to someone else what I feel, I must translate my feelings into his language – saying things, that is, as if they were what I feel, so that he, reading them, will feel exactly what I felt. And since this someone is presumed by art to be not this or that person but everyone (i.e., that person common to all persons), what I must finally do is convert my feelings into a typical human feeling, even if it means perverting the true nature of what I felt.

Abstract things are hard to understand, because they don’t easily command the reader’s attention, so I’ll use a simple example to make my abstractions concrete. Let’s suppose that, for some reason or other (which might be that I’m tired of keeping the books or bored because I have nothing to do), I’m overwhelmed by a vague sadness about life, an inner anxiety that makes me nervous and uneasy. If I try to translate this emotion with close-fitting words, then the closer the fit, the more they’ll represent my own personal feeling, and so the less they’ll communicate it to others. And if there is no communicating it to others, it would be wiser and simpler to feel it without writing it. But let’s suppose that I want to communicate it to others – to make it into art, that is, since art is the communication to others of the identity we feel with them, without which there would be no communication and no need for it. I search for the ordinary human emotion that will have the colouring, spirit and shape of the emotion I’m feeling right now for the inhuman, personal reason of being a weary bookkeeper or a bored Lisboan. And I conclude that the ordinary emotion which in ordinary souls has the same characteristics as my emotion is nostalgia for one’s lost childhood.

Now I have the key to the door of my theme. I write and weep about my lost childhood, going into poignant detail about the people and furniture of our old house in the country. I recall the joy of having no rights or responsibilities, of being free because I still didn’t know how to think or feel – and this recollection, if it’s well written and visually effective, will arouse in my reader exactly the same emotion I was feeling, which had nothing to do with childhood.

I’ve lied? No, I’ve understood. That lying, except for the childish and spontaneous kind that comes from wanting to be dreaming, is merely the recognition of other people’s real existence and of the need to conform that existence to our own, which cannot be conformed to theirs. Lying is simply the soul’s ideal language. Just as we make use of words, which are sounds articulated in an absurd way, to translate into real language the most private and subtle shifts of our thoughts and emotions (which words on their own would never be able to translate), so we make use of lies and fiction to promote understanding among ourselves, something that the truth – personal and incommunicable – could never accomplish.

Art lies because it is social. And there are two great forms of art: one that speaks to our deepest soul, the other to our attentive soul. The first is poetry, the second is the novel. The first begins to lie in its very structure; the second in its very intention. One purports to give us the truth through lines that keep strict metres, thus lying against the nature of speech; the other purports to give us the truth by means of a reality that we all know never existed.

To feign is to love. Whenever I see a pretty smile or a meaningful gaze, no matter whom the smile or gaze belongs to, I always plumb to the soul of the smiling or gazing face to discover what politician wants to buy our vote or what prostitute wants us to buy her. But the politician that buys us loved at least the act of buying us, even as the prostitute loved being bought by us. Like it or not, we cannot escape universal brotherhood. We all love each other, and the lie is the kiss we exchange.
