What is this jest in majesty? This ass in passion? How do God and Devil combine to form a live dog? - Vladimir Nabokov

I have often noticed that we are inclined to endow our friends with the stability of type that literary characters acquire in the reader's mind. [...] Whatever evolution this or that popular character has gone through between the book covers, his fate is fixed in our minds, and, similarly, we expect our friends to follow this or that logical and conventional pattern we have fixed for them. Thus X will never compose the immortal music that would clash with the second-rate symphonies he has accustomed us to. Y will never commit murder. Under no circumstances can Z ever betray us. We have it all arranged in our minds, and the less often we see a particular person, the more satisfying it is to check how obediently he conforms to our notion of him every time we hear of him. Any deviation in the fates we have ordained would strike us as not only anomalous but unethical. We could prefer not to have known at all our neighbor, the retired hot-dog stand operator, if it turns out he has just produced the greatest book of poetry his age has seen.

God does not exist, as neither does our hereafter, that second bogey being as easily disposed of as the first. Indeed, imagine yourself just dead — and suddenly wide awake in Paradise where, wreathed in smiles, your dear dead welcome you.
Now tell me, please, what guarantee do you possess that those beloved ghosts are genuine; that it is really your dear dead mother and not some petty demon mystifying you, masked as your mother and impersonating her with consummate art and naturalness? There is the rub, there is the horror; the more so as the acting will go on and on, endlessly; never, never, never, never, never will your soul in that other world be quite sure that the sweet gentle spirits crowding about it are not fiends in disguise, and forever, and forever, and forever shall your soul remain in doubt, expecting every moment some awful change, some diabolical sneer to disfigure the dear face bending over you.

No writer in a free country should be expected to bother about the exact demarcation between the sensuous and the sensual; this is preposterous; I can only admire but cannot emulate the accuracy of judgment of those who pose the fair young mammals photographed in magazines where the general neckline is just low enough to provoke a past master's chuckle and just high enough not to make a postmaster frown.
