The quote from Dante that appears on Fin's computer is "Abandon all hope, ye who enter here." The quote comes from The Inferno (Italian for "Hell"), which is the first part of Dante Alighieri's 14th-century epic poem The Divine Comedy, specifically from Canto III. The original Italian phrase is "Lasciate ogne speranza, voi ch'intrate". Verbatim, the line translates as "Leave (lasciate) every (ogne) hope (speranza), ye (voi) that (ch') enter (intrate)."
There are many English translations of this famous line. Some examples include:
All hope abandon, ye who enter here - Henry Francis Cary (1805–1814)
All hope abandon, ye who enter in! - Henry Wadsworth Longfellow (1882)
Leave every hope, ye who enter! - Charles Eliot Norton (1891)

A complete English translation of the inscription above the gates of Hell:
"Through me you pass into the city of woe:
Through me you pass into eternal pain:
Through me among the people lost for aye.
Justice the founder of my fabric moved:
To rear me was the task of Power divine,
Supremest Wisdom, and primeval Love.
Before me things create were none, save things
Eternal, and eternal I endure.
All hope abandon, ye who enter here."
