Disease is a conviction, and I was born with that conviction. - Italo Svevo

È un modo comodo di vivere quello di credersi grande di una grandezza latente.

Wine is a great danger, especially because it doesn't bring truth to the surface. Anything but the truth, indeed: it reveals especially the past and forgotten history of the individual rather than his present wish; it capriciously flings into the light also all the half-baked ideas with which in a more or less recent period one has toyed and then forgotten.

Svevo’s Zeno, with his complicated relationship with psychoanalysis, is an unforgettable embodiment of the situation of the 20th century humans who have been persuaded by ideologies that they should not listen to [the moral compass of] conscience.
They may believe they are very modern and sophisticated, but in the end they are not able to impose order on the chaos of consciousness and their lives end up in moral bankruptcy.
…
Zeno lives in an era of turmoil, and ultimately does not succeed in recovering his conscience. However, he has his opportunities to understand that, notwithstanding what the psychoanalyst tells him, only [the moral compass of] conscience can impose the needed order to what is otherwise a chaotic flow of disconnected pieces of consciousness. These opportunities come when he is confronted with suffering and the world’s injustice, although neither he nor the other main characters in the novel profit of them.
