The One True Platonic Heaven: A Scientific Fiction on the Limits of Knowledge

by John L. Casti

Book Overview

By the author of The Cambridge Quintet, John L. Casti's new book continues the tradition of combining science fact with just the right dose of fiction. Part novel, part science ? wholly informative and entertaining.

In the fall of 1933 the newly founded Institute for Advanced Study in Princeton, New Jersey, welcomed its first faculty member, Albert Einstein. With this superstar on the roster, the Institute was able to attract many more...

Intellectual heaven on earth

What Casti means by the title 'One True Platonic Heaven' is polyvalent - in the first place, it is frequent reference to the IAS, the Institute for Advanced Study at Princeton University, a think-tank founded for the advancement of pure science. So adamant are some that it remain 'pure' rather than 'applied', that when one of their number proposes to bring a computing device in, there is controversy among the members, that this would end up being an 'application', and implicit slippery slopes abound.Of course, the timing of this novel (and it is a novel) is the early twentieth century - the prologue begins with snapshots of various points prior to World War II, key moments in the development of mathematics and scientific epistemology. The core of the book takes place just after the war, in Princeton, as the earliest computing machines (ENIAC, anyone?) have been developed by the military, and are now being further developed for both civilian and military applications.The cast of characters Casti draws is impressive - the core group includes Einstein, Godel, von Neumann, Oppenheimer, and Strauss; other 'also starring' roles go to T.S. Eliot (Oppenheimer was a poet on the side, and the idea of the limits of knowledge is a multi-disciplinary task), Goldstein, Weyl, Pauli, Bohm and others. Casti draws these people together in informal and formal settings, preferring the former to the later - walking to campus and having discussions, gatherings at tea-time, etc. Casti injects the human element into the mix (we are told of Godel's eccentricity such that he starved himself to death no fewer than three times, for example) - his descriptions help the narrative flow of the novel, but can be distracting for those who wish to get directly to the heart of the arguments.The book is rather thin - 160 pages of text, small-format pages at that - and while the subject matter is rather high end intellectual thinking, in fact the substance of the book probably only consists of about a third of those pages; the rest is psychological tid-bits about the characters (enlightening from an historical standpoint, and pointing the way in some respects as to why people thought the ways they did) or narrative linkages, so it can be read fairly quickly (unlike a mathematics textbook, which would more likely take a longer time). There are no equations here - Casti is assuming some knowledge of mathematics in general theory; Casti also assumes a grounding in physics and in philosophy. Without some background in at least one of these disciplines, the reader is likely to be lost at several points.It is fascinating to realise that the limitations on knowledge discussed in this hypothetical construct by such exalted twentieth-century thinkers contain elements still on the table for discussion today. This is where another meaning of the 'one true Platonic heaven' comes into play - it is a theoretical construct, akin to the Forms, without direct substance, yet reflected in import

Casti does it again!

John Casti has emerged as the most articulate, humorous and sophisticated science writer in the world in recent years. Writing on topics as diverse as Artificial Intelligence, Mathematics and Complexity, Biology and Genetics and the Philosophy of Science, he now has taken the boldest step as of yet, an effort to debate the limits of knowledge itself. As in his earlier book, The Cambridge Quintet, Casti weaves together a fictional set of discussions between famous scientists set in the 1940s at the Institute for Advanced Study, Princeton, the "one, true, platonic heaven", a place where the most austere and profound theorists in the world could come and think. Participants include such luminaries as J. Robert Oppenheimer (who was director of the institute then), Kurt Godel, Freeman Dyson, John von Neumann and the great Einstein himself. The discussions take place at diverse locations and times; in the common room during tea time, between Einstein and Godel during walks from the institute to the house, and at a party hosted by the great mathematician John von Neumann. The topic? What are the limits of our knowledge, in Physics, in Mathematics, in Social Sciences, in Philosophy. At the background are minor discussions of matters involving whether Kurt Godel should be made a permanent member, and whether von Neumann should build the first ever computer in the Institute. There's also a cameo appearance by T. S. Eliot, who was an invited member for a year. I have to admit that this book is not as profound as The Cambridge Quintet. However, Casti has an uncanny knack for constructing life size figures of famous scientists, and making the discussions relevant, articulate and accessible. There are of course, a few cliche lines coming from each of the scientists, but then since the discussions are fictional, who knows what all of them would have actually said. In the end, there is no concrete conclusion, as there cannot be any about such a profound topic. But I closed the book feeling sure only about one thing, that we must continue the quest for the limits of knowledge, even if we don't know what they are at this moment. This is surely an example where, for once, the journey is infinitely more interesting and important than the destination.

Unique and enjoyable work

Casti's unique blending of science and fiction is a delight to read. The story takes place against the backdrop of the early years of the Princeton Institute for Advanced Study--a true citadel of genius if there ever was one. Characters like Einstein, Kurt Godel, J. Robert Oppenheimer (who was its director), Hermann Weyl, Wolfgang Pauli, and John Wheeler (not all of whom were at the institute) come to life as they discuss and debate the great scientific issues of the day. Much of the story transpires over conversations in the halls of the institute, or at the gregarious and likeable von Neumann's cocktail parties. Some of the best conversations are between Godel and Einstein as they stroll along the streets of Princeton. The gnomish and reclusive Godel was one of the few people who could surprise Einstein, and one time Godel (who was most famous as a logician) said he'd just happened to be playing around with Einstein's relativistic field equations and had found a solution that had escaped Einstein that suggested that time didn't exist, or at least there was no meaning to our ideas of temporal succession. In this solution, closed, relativistic, timelike lines existed in space, and one could go forward in time as well as backward. Einstein is stunned and impressed by this little bombshell that Godel had dropped on him--yet another example of Godel's amazing genius, and why he was known as the "Grand Exalted Ruler" of the "One True, Platonic Heaven"--the Princeton Institute for Advanced Study. And that's not to mention the fact that Godel's famous incompleteness proof threw into doubt the great Hilbert's entire program of completeness in mathematics which had been widely supported. This is just one of the many fascinating discussions which Casti skillfully uses to explore and explain very clearly and concisely not only some esoteric science but also such questions as the ethics of science, aesthetics in science, Einstein's controversial and infamous stand on quantum indeterminacy, and the scientist's place in society.Casti also manages to inject some drama into the story with the controversy surrounding von Neumann's proposal for building the first big electronic computer at the Institute--a proposal which many of the Institute's professors opposed because it was against the Institute's stated mission of doing only pure and not applied research. Through some clever politicking and persuasion, Oppenheimer manages to get the project approved, although it was the only such engineering project ever undertaken at the Institute, and nothing else like it was ever done again. Another side story involves Godel's elevation to full professor which had been delayed because of some of his personal quirks and otherworldly nature--the job of full professor also involving not just thinking about your subject all day long but also requiring spending considerable time in various administrative duties which the other professors thought Godel unsuited for. But Oppenhe
