Immanuel Velikovsky has been labelled a pseudoscientist by some (main article: Pseudoscience), and a genius by others. Han Kloosterman asked the rhetorical question: "Is Velikovsky a charlatan or a genius, or both?"
Brian Moore writes:
- "Another celebrated Freudian, Dr Paul Federn, recorded in 1947  the following view of Velikovsky:
- "A genius. A great man. An excellent psychoanalyst. An M.D. member of the Palestine group. Some revolutionary ideas that some people think are crazy, but he is a genius. Would not consider him for a teacher, but as an analyst I have sent him some of my most difficult cases."
Frederic B. Jueneman writes:
- "In the field of Velikovsky's historical reconstructions, there are increasing numbers of scholars who are privately proclaiming him a genius for putting his finger on the perennial sorespot in Egyptian, Greek, and Anatolian chronology -- the roughly six centuries of dark ages of Mediterranean culture that abruptly stopped, had its long hiatus, and continued precisely where it left off as if nothing had happened. Velikovsky simply went to the heart of the problem and said that Egyptian chronology, the standard meterstick of the Middle East and Mediterranean civilizations, is in chaos and in error by as much as 800 years. [..]
- "Quite frankly, in my view Velikovsky's efforts were not the labors of a pseudo-scientist, because his work has touched on too many things which preemptively have been proven correct, or with furthered knowledge might be proven one way or another. I am convinced that the major thrust of his opponents' arguments is that no one man can cut across so many disciplines with any authority or understanding at all, and in demeaning the man they merely demean their own inadequacy."
Reporting on the 1974 AAAS conference, Scientists Confront Velikovsky', the Observer newspaper wrote:
- "it wasn't Velikovsky's theories that angered the professors so much -- though they were heretical enough -- as the fact that thousands of their students swallowed them with an almost religious fervor, and saw the craggy, white-haired scholar as a wronged genius."
- "When in 1971 I first read Worlds in Collision it was like opening the doors to a new, fascinating world. As soon as I had read the book and considered its contents, I was convinced that Velikovsky's reconstruction of ancient astronomical events was essentially correct, and since then I have endeavoured to find explanations wherever Velikovsky's theories seemed to be afflicted with theoretical difficulties. [..] To me there is no doubt that Immanuel Velikovsky was one of the greatest geniuses that ever lived."
- "Once the panorama of human history has been seen through the prism of Velikovsky's genius, the implications of his work press in from all sides." [..] "I believe Velikovsky to be one of the greatest geniuses of the millennium."
- "If Velikovsky's first paradigm was a serious and tragic misidentification, then his second paradigm was a stroke of a genius, a genius in cosmology, though not one in celestial mechanics. "
- "Dr. Immanuel Velikovsky died last November. Unlike his friends Albert Einstein and Sigmund Freud, Dr. Velikovsky went to his grave deprived of plaudits from his peers. It is my belief that he was, indeed, the last true Renaissance man: his genius will be recognized after his death even more than the famous painters of the nineteenth century."
Philosopher David Stove writes:
- "Who is the most important thinker of the present century? Einstein, many would say. I am too ignorant, unfortunately, to judge whether that is true. Change the question a little: which thinker is the most important for the light he has thrown on human and terrestrial affairs? Freud? Wittgenstein? Konrad Lorenz? These answers I can judge, and I do not agree with any of them. My answer is, Immanuel Velikovsky."
