8 April 1891
The obscenity of nostrils and mouths; the ignominious cupidity of smiles and women encountered in the street; the shifty baseness on every side, as of hyenas and wild beasts ready to bite: tradesmen in their shops and strollers on their pavements. How long must I suffer this? I have suffered it before, as a child, when, descending by chance to the servant's quarters, I overheard in astonishment their vile gossip, tearing up my own kind with their lovely teeth.

This hostility to the entire race, this muted detestation of lynxes in human form, I must have rediscovered it later while at school. I had a repugnance and horror for all base instincts, but am I not myself instinctively violent and lewd, murderous and sensual? Am I any different, in essence, from the members of the riotous and murderous mob of a hundred years ago, who hurled the town sergeants into the Seine and cried, 'String up the aristos!' just as they shout 'Down with the army!' or 'Death to the Jews!

The madness of the eyes is the lure of the abyss. Sirens lurk in the dark depths of the pupils as they lurk at the bottom of the sea, that I know for sure - but I have never encountered them, and I am searching still for the profound and plaintive gazes in whose depths I might be able, like Hamlet redeemed, to drown the Ophelia of my desire.

Masks! I see them everywhere. That dreadful vision of the other night - the deserted town with its masked corpses in every doorway; that nightmare product of morphine and ether - has taken up residence within me. I see masks in the street, I see them on stage in the theatre, I find yet more of them in the boxes. They are on the balcony and in the orchestra-pit. Everywhere I go I am surrounded by masks. The attendants to whom I give my overcoat are masked; masks crowd around me in the foyer as everyone leaves, and the coachman who drives me home has the same cardboard grimace fixed upon his face!

It is truly too much to bear: to feel that one is alone and at the mercy of all those enigmatic and deceptive faces, alone amid all the mocking laughs and the threats embodied in those masks. I have tried to persuade myself that I am dreaming, and that I am the victim of a hallucination, but all the powdered and painted faces of women, all the rouged lips and kohl-blackened eyelids... all of that has created around me an atmosphere of trance and mortal agony. Cosmetics: there is the root cause of my illness!

But I am happy, now, when there are only masks! Sometimes, I detect the cadavers beneath, and remember that beneath the masks there is a host of spectres.

...the presence of others has become even more intolerable to me, their conversation most of all. Oh, how it all annoys and exasperates me: their attitudes, their manners, their whole way of being! The people of my world, all my unhappy peers, have come to irritate, oppress and sadden me with their noisy and empty chatter, their monstrous and boundless vanity, their even more monstrous egotism, their club gossip... the endless repetition of opinions already formed and judgments already made; the automatic vomiting forth of articles read in those morning papers which are the recognised outlet of the hopeless wilderness of their ideas; the eternal daily meal of overfamiliar cliches concerning racing stables and the stalls of fillies of the human variety... the hutches of the 'petites femmes' - another worn out phrase in the dirty usury of shapeless expression!

Oh my contemporaries, my dear contemporaries...

Their idiotic self-satisfaction; their fat and full-blown self-sufficiency: the stupid display of their good fortune; the clink of fifty- and a hundred-franc coins forever sounding out their financial prowess, according their own reckoning; their hen-like clucking and their pig-like grunting, as they pronounce the names of certain women; the obesity of their minds, the obscenity of their eyes, and the toneless-ness of their laughter! They are, in truth, handsome puppets of amour, with all the exhausted despondency of their gestures and the slackness of their chic...

Chic! A hideous word, which fits their manner like a new glove: as dejected as undertakers' mutes, as full-blown as Falstaff...

Oh my contemporaries: the ceusses of my circle, to put it in their own ignoble argot. They have all welcomed the moneylenders into their homes, and have been recruited as their clients, and they have likewise played host to the fat journalists who milk their conversations for the society columns. How I hate them; how I execrate them; how I would love to devour them liver and lights - and how well I understand the Anarchists and their bombs!

Although he had always been a gentleman till then, he had 'caught his century', a disease impossible to analyze but by this simple phrase.

The fancies that take their monstrous birth from the spinelessness and boredom of usurped wealth bring in their wake every defect ... and though rich men's crimes escape the law, protected as they are by the cowardice of governments and people, Nature, more real than society, sets her anarchic example by abandoning the wretched time servers of Capital to the shame and madness of the worst aberrations.
