Katie Roiphe's book raises critical questions which concern not only the relationship between Dodgson and Alice Liddell, but the very idea of attraction between humans.
That he was attracted to Alice, to the point of obsession, is not in question. Was he sexually attracted to her? In truth, we can never know, but in examining the nature of attraction, especially in the light of the 20 year age difference, we are lead into many interesting areas.
Katie Roiphe's projection that he finally made the quantum leap into photographing Alice naked, as he had done with other young girls, is not entirely unreasonable. The reclining nude 'study' of Evelyn Hatch is one of the few surviving examples of his child nude phase. Apparently he took a substantial number of child nude photographs, of which only perhaps four have survived.
Whether the attraction was based on past-life karma, mere aesthetics or something darker is again unknown. His sexual attraction to an eleven year old Alice is not unthinkable as there is an inevitable level of male biological response to the presence of sexually maturing females, based on a simple reproductive urge. While there is no estrus response as such in humans, there will be other factors, other signals, which trigger attraction and the equivalent of a mating ritual.
His attraction of whatever kind to the four year old Alice, is more problematic. Given his ability to think in child-like fantasy terms, as evinced by the books, it may be that at some level, the four year old in Carroll had a simple crush on the young Alice, and that simultaneously he projected her future development into adult form as a possible future soul mate.
There is still debate over whether he actually proposed to the eleven year old Alice, and whether this, rather than the nude photography, may have been the final straw for her family.
Whatever the reality may have been, Roiphe's story is challenging and well developed, and not entirely unsympathetic to his situation, projected or otherwise. Roiphe's view seems to be that even if he was sexually attracted to her, he did at least control himself.
For me, the bottom line in terms of the real world, is that if there is a male hanging around your family 'because he loves children so much', there is a 99% chance he has pedophile tendencies and should not be trusted under any circumstances.
The downside of Carroll/Dodgson is that he was a pompous oaf, who wrote very condescendingly about others, imagining that he could charm his way into the lives of an infinite number of young girls and their often witless parents.
Was he a calculating monster? I think not. Was he in love with Alice? Yes. Were his attentions and the form they took excessive? Yes.
Somewhere in between those who dismiss him as a pedophile and those who would completely whitewash his disturbing obsessions, may well lie the truth.
