A Diatribe from the Remains of Dr. Fred McCabe

by Daniel Rourke

About a month ago in handling the remains of one Dr. Fred McCabe I found rich notes of contemplation on the subject of information theory. It appears that Fred could have written an entire book on the intricacies of hidden data, encoded messages and deceptive methods of transmission. Instead his notes exist in the form of a cryptic assemblage of definitions and examples, arranged into what Dr. McCabe himself labelled a series of ‘moments’.

I offer these moments alongside some of the ten thousand images Dr. McCabe amassed in a separate, but intimately linked, archive. The preface to this abridged compendium is little capable of preparing one for the disarray of material, but by introducing this text with Fred’s own words it is my hope that a sense of the larger project will take root in the reader’s fertile imagination.

The Moment of the Message: A Diatribe

by Dr. Fred McCabe

More than ten thousand books on mathematics and a thousand books on philosophy exist for every one upon information. This is surprising. It must mean something.

I want to give you a message. But first. I have to decide how to deliver the message.

This is that moment.

I can write it down, or perhaps memorise it – reciting it in my head like a mantra, a prayer chanted in the Palace gardens. And later, speaking in your ear, I will repeat it to you. That is, if you want to hear it.

I could send it to you, by post, or telegram. After writing it down I will transmit it to you. Broadcasting on your frequency in the hope that you will be tuned in at the right moment. Speaking your language. Encoded and encrypted, only you will understand it.

I have a message for you and I want you to receive it. But first. I have to decide what the message is.

This is that moment:

This is the moment of the message

From the earliest days of information theory it has been appreciated that information per se is not a good measure of message value. The value of a message appears to reside not in its information (its absolutely unpredictable parts) but rather in what might be called its redundancy—parts predictable only with difficulty, things the receiver could in principle have figured out without being told, but only at considerable cost in money, time, or computation. In other words, the value of a message is the amount of work plausibly done by its originator, which its receiver is saved from having to repeat.

This is the moment my water arrived at room temperature

The term enthalpy comes from the Classical Greek prefix en-, meaning “to put into”, and the verb thalpein, meaning “to heat”.

For a simple system, with a constant number of particles, the difference in enthalpy is the maximum amount of thermal energy derivable from a thermodynamic process in which the pressure is held constant.

This is the moment the wafer became the body of Christ

The Roman Catholic Church got itself into a bit of a mess. Positing God as the victim of the sacrifice introduced a threshold of undecidability between the human and the divine. The simultaneous presence of two natures, which also occurs in transubstantiation, when the bread and wine become the body and blood of Christ, threatens to collapse the divine into the human; the sacred into the profane. The question of whether Christ really is man and God, of whether the wafer really is bread and body, falters between metaphysics and human politics. The Pope, for all his failings, has to decide the undecidable.
