A Zionist is democratic?

To make such an outrageous statement, after seeing the genocide the Palestinians continue to face, is insulting and offensive. Zionism is not about supporting Jewish rights, it's about supporting the right for Jewish people to savagely torture and kill an indigenous population of Palestinians and then claim ownership of the their land and property. Jewish scholars and Rabbis do not support Zionism. Rabbi Weiss, Ilan Pappé ..to name only a few, proving how it was founded on lies. I guess if Koestler can be a democratic Zionist, Josef Mengele can now be called a humanitarian surgeon. Offensive? Yes. Committing atrocities is never justified no matter how you label them.

Koestler and Kepler: The Perfect Fusion

"The Watershed" by Arthur Koestler is a magnificent piece of literature that is unique, yet well organized and informative of the life and works of Johannes Kepler. Koestler does a great job in showing how the modern world-view was slowly replaced by the medieval world-view and how science has progressively advanced. He has a direct goal to demonstrate the distinction between Humanities and Sciences. I believe it is a necessary book to read for anyone interested in science. It enables the reader with a greater understanding of the universe and the planets in our solar system. It is also unique in showing the struggles Kepler and many scientists face during their lives that they must overcome. Kepler's personal writings fused with Koestler's outside commentary provide for an informative read applicable to any reader. Koestler shows how Kepler's studies directly influenced modern astronomy and physics through his three laws, which were pivotal in the works of Isaac Newton. Also, he effectively demonstrates the process in which Kepler drew up his theories and found his discoveries, as well as the resistance he faced from the general public, himself, and other factors. "The Watershed is one biography that should be read by anyone interested in physics, astronomy, or any other science.

The Watershed

This book is an excellent read for all inquiring minds, young and old. As a young avid reader, it was this book and the memory of Koestler's words describing not only Kepler himself, but of the watershed crest where thought and reason began to cascade down the slope of knowledge; it was this that ignited within me the spark that touched off a greater quest for knowledge. My son is now nine, and I hope that this book may have the some of the same cathartic effect on him.

Stuck between two worlds

Arthur Kooestler was a true 20th century man. At various periods in his life he was a refugee, communist, Zionist and democratic-socialist. He was a true cosmopolitan, in the positive sense, and also a student of the history of science.The Watershed is a hymn to a forgotten hero of science - the astronomer J. Kepler who lived in the latter part of the 16th and early part of the 17th centuries. Koestler projects him as a true genius, the father of modern cosmology, who laid the foundation for modern astronomy and who paved the way for Newtonian physics but never realized the importance of his three laws. Kepler was caught between two worlds: the medieval theological world based on Aristotelian physics and modern science based on observation and calculation. If you like he was caught between his heart and his mind. This is readily seen in his works which range from the mystic to the scientific. Keplers three laws were:1.the planets do not orbit in circles but in ellipses.2.the speed of the planets vary during their orbit.3.there is an exact correlation between a planets' period of revolution around the sun and it's distance from the sun: the squares of the periods of revolution of any two planets are as the cubes of their mean distance from the sun.In fact, Kepler had discovered gravity but didn't realize it. This great mind couln't make the the final jump into modernity. This book is a really fine portrayal of Kepler as a great thinker, a man of his times and as Everyman with the same personal problems we all experience.I strongly reccomend this forgotten work to anybody interested in the history of science.
