Walker Percy’s foreword to the book cannot be bettered:
Perhaps the best way to introduce this novel — which on my third reading of it astounds me even more than the first — is to tell of my first encounter with it. While I was teaching at Loyola in 1976 I began to get telephone calls from a lady unknown from me. What she proposed was preposterous. It was not that she had written a couple of chapters of a novel and wanted to get into my class. It was that her son, who was dead, had written an entire novel during the early sixties, a big novel, and she wanted me to read it. Why would I want to do that? I asked her. Because it is a great novel, she said.
Over the years I have become very good at getting out of things I don’t want to do. And if ever there was something I didn’t want to do, this was surely it: to deal with the mother of a dead novelist and, worst of all, to have to read a manuscript that she said was great, and that, as it turned out, was a badly smeared, scarcely readable carbon.
But the lady was persistent, and it somehow came to pass that she stood in my office handing me the hefty manuscript. There was no getting out of it; only one hope remained — that I could read a few pages and that they would be bad enough for me, in good conscience, to read no farther. Usually I can do just that. Indeed the first paragraph often suffices. My only fear was that this one might not be bad enough, or might be just good enough, so that I would have to keep reading.
In this case I read on. And on. First with the sinking feeling that it was not bad enough to quit, then with a prickle of interest, then a growing excitement, and finally an incredulity: surely it was not possible that it was so good. I shall resist the temptation to say what first made me gape, grin, laugh out loud, shake my head in wonderment. Better let the reader make the discovery on his own.
Here at any rate is Ignatius Reilly, without progenitor in any literature I know of — slob extraordinary, a mad Oliver Hardy, a fat Don Quixote, a perverse Thomas Aquinas rolled into one — who is in violent revolt against the entire modern age, lying in his flannel nightshirt, in a back bedroom on Constantinople Street in New Orleans, who between gigantic seizures of flatulence and eructations is filling dozens of Big Chief tablets with invective. …
I hesitate to use the word comedy — though comedy it is — because that implies simply a funny book, and this novel is a great deal more than that. A great rumbling farce of Falstaffian dimensions would better describe it; commedia would be closer to it.
It is also sad. One never quite knows where the sadness comes from — from the tragedy at the heart of Ignatius’s great gaseous rages and lunatic adventures or the tragedy attending the book itself.
The tragedy of the book is the tragedy of the author — his suicide in 1969 at the age of thirty-two. Another tragedy is the body of work we have been denied.
It is a great pity that John Kennedy Toole is not alive and well and writing. But he is not, and there is nothing we can do about it but make sure that this gargantuan tumultuous human tragicomedy is at least made available to a world of readers.
I was asked whether the book was canonical for Louisiana, and I am not sure that it was when I first read it not too many years after its publication, but surely it is now. It is a note-perfect rendition of aspects of New Orleans, and much more than that.
