“There is titillating pleasure in looking back at the past and asking oneself, 'What would have happened if...' and substituting one chance occurrence for another, , observing how, from a gray, barren, humdrum moment in one’s life, there grows forth a marvelous rosy even that in reality had failed to flower. A mysterious thing, this branching structure of life: one senses in every past instant a parting of ways, a 'thus' and an 'otherwise', with innumerable dazzling zigzags bifurcating and trifurcating against the dark background of the past.”

“One is always at home in one's past...”

“It is easy for him and me to decipher now a past destiny; but a destiny in the making is, believe me, not one of those honest mystery stories where all you have to do is keep an eye on the clues.”

“What chatty Madam Shpolyanski mentioned had conjured up Mira's image with unusual force. This was disturbing. Only in the detachment of an incurable complaint, in the sanity of near death, could one cope with this for a moment. In order to exist rationally, Pnin had taught himself...never to remember Mira Belochkin - not because...the evocation of a youthful love affair, banal and brief, threatened his peace of mind...but because, if one were quite sincere with oneself, no conscience, and hence no consciousness, could be expected to subsist in a world where such things as Mira's death were possible. One had to forget - because one could not live with the thought that this graceful, fragile, tender young woman with those eyes, that smile, those gardens and snows in the background, had been brought in a cattle car and killed by an injection of phenol into the heart, into the gentle heart one had heard beating under one's lips in the dusk of the past.”

“You see - the moulded whimsy of a friezeon a portico keeps us from recognizing,sometimes, the symmetry of the whole...You will leave; we'll forget one another;but now and then the name of a street,or a street organ weeping in the twilight,will remind us in a more vivid and moretruthful way than thought could resurrector words convey, of that main thingwhich was between us, the main thing whichwe do not know ... And in that hour, the soulwill miraculously sense the charmof past trifles, and we will understandthat in eternity all is eternal”

“And what agony, thought Krug the thinker, to love so madly a little creature, formed in some mysterious fashion (even more mysterious to us than it had been to the very first thinkers in their pale olive gloves) by the fusion of two mysteries, or rather two sets of a trillion of mysteries each; formed by a fusion which is, at the same time, a matter of choice and a matter of chance and a matter of pure enchantment; thus formed and then permitted to accumulate trillions of its own mysteries; the whole suffused with consciousness, which is the only real thing in the world and the greatest mystery of all.”

“...memory can restore to life everything except smells, although nothing revives the past so completely as a smell that was once associated with it.”
