Food for thought for sure, From Hell is a complex piece of work with many layers of human emotions, expressions, and delusions.
One thing I particularly like about Alan Moore is his all-pervading kindness to everyone he presents in his works, both villains and heroes, victims and criminals.
So, we see Sir William Gull— a genius, a murderer, deranged to many but sure of his superiority only found his true nature of derangement and inferiority in his visit to a higher plain.
There are some memorable panels and monologues that will keep me thinking for quite a while.
Although Moore used Hinton's fourth dimension as a central concept of this work, he— probably with his modern sense of four-dimensional space understood the fourth dimension as time, whereas Hinton's was an Euclidean one. However, since the Euclidean dimensions are all spatial it may have helped Moore to think along the line where he can craft a simile like the panels above— where he compared the causality with architecture.
A masterpiece!
The footnotes alone are almost a book unto themselves(!)
Yes. They allow us to take a peek at Moore's mind. I remember how sound his idea about Anarchy was in V for Vendetta. He gives so much thought to everything he writes.
