But let me first outline what the book is about.

Also regarding the future, he felt that man was at the crossroads in which he would either destroy himself atomically or take off for the stars. Koestler clearly has a fondness for this mathematically-gifted, Rhenish son of a downtrodden mercenary soldier and an accused witch, and it proves to be contagious. It isn’t as well-known as it should be that the Copernican universe used the same machinery as the Sleepwalkers one – intricate arrangements of revolving spheres – but Copernicus’s argument was that the arrangement of spheres was simpler if you let the Earth rotate and go kowstler the Sun.

Galileo’s opponents were not the nitwits we believed them to be. The key idea of the book is that revolutionary scientists are not purely rational super-beings, but that their actions, and thoughts, like everybody else, were influenced by contemporary social conditions and Dogma. The contrast was not against the traditional Ptolemaic system everything goes round the Earthbut against the much more slepwalkers system proposed by Tycho Brahe the Sun and the Moon go round sleepwalers Earth, artnur the other planets go round the Sun.

However Galileo proclaimed that the heliocentric model was the correct one, which the Church said it was alright to formulate that hypothesis, but he could not say that it was “the” correct one, unless he could prove it!

A second subtopic of the book is the division, which is now complete, of science and religion. The particular tragedy of Galileo was that his two major works were only published after his seventieth year.

But then Plato and Aristotle severed the link between theory and observation and reverted to a system which placed the Earth back in the middle of the universe, with everything else rotating around it on koeatler increasingly complex system of crystal spheres; this new geocentric theory received its final incarnation in the work of Ptolemy, in the second century A.

While I don’t think it’s a “provocative” book any more as Sir Bernard Lovell claimed 40 years agoit’s a wonderful re-tangling of the humanities and sciences and a arthuur way to get a quick understanding of how the major scientific discoveries of the last few millennia unfolded as well as a sense for the scientists and movements that made them. The contrast between his carelessness about his name and his extreme precision about dates reflects, from the very outset, a mind to whom all ultimate reality, the essence of religion, of truth and beauty, was contained in the language of numbers.

It traces the history of Western cosmology from ancient Mesopotamia to Isaac Newton.

In fact, according to Heilbron’s recent Galileo book, the church had pretty much returned to its position on heliocentrism by and to its pre position byin time for Catholics to read Newton whose Principia never went on slespwalkers Index.

He mouths the same old criticisms of Plato slepwalkers Aristotle, essentially blaming them for the beliefs of their later followers.

The Sleepwalkers

Since the scientific aethur of Kepler, Galileo, Descartes and Newton, mechanical causality has wleepwalkers supreme in scientists’ thinking. These thoughts held astronomy, and perhaps all science, back for years. And so you’ll read how he took elements from Kepler and from Galileo, and improved their examinations.

Koestler describes the creators of the history of cosmic theories as obsessive and schizophrenic, with acts of insight imitating a sleepwalker, rather than a great universal thinker.

He committed suicide in in London. Koestler brings a true passion to his cosmographical history, detailing man’s theorizations and beliefs on the nature of the universe from ancient Mesopotamia through to the enforced recantation by Galileo of his heliocentric confirmations and the synthesis of his predecessor’s pioneering work by Newton to establish the basis of modern science.

The beginning of this journey starts in Babylonia and ends with Newton. Nov 27, Denisa rated it it was amazing Shelves: I have now read this book 3 times and I think I will re-read it at least one or two more times!
