A summary of the historical work of Immanuel Velikovsky
This text is also available in Dutch
This is a text that I wrote in 2009. After finishing the text I read more, for example the work of the SIS (Society for Interdisciplinary Studies) that publishes the "SIS-Review" and the "Chronology and Catastrophism Review" since 1975. This might have caused me to change my text for example in the last part. Yet I prefer to keep the text, in the way I wrote it in 2009. In 2011 I decided to translate the text in English and I want to thank members of the SIS who helped me with the translation.
