This is a new low for Lissu Sympathizers,Just admit the guy blew it by letting the mouth control the talking instead of involving his brain. In one side he shames Nyerere, another side he is shaming CCM for now listening to Nyerere and faithfully follow his policies, which is which?why should CCM follow policies of a lair as per Lissu assertions?
Baring gross irregularities in ones PhD, there is absolutely no viable reason to discuss the validity of Mwakyembe's credentials, unless you have no idea whats involved in level 8 qualifications.
The entire premise of research at that level is original thinking, and its actually plausible for this line of thinking to be modified over time,same way Newton being Utterly wrong with regards to laws of physics doesn't make Cambridge waive his mathematics professorship postmortem.
Steven Hawking has made several comments with regards to his the bing bang theories and some of them are exact opposite of what he proposed many years ago.in fact i know a guy who even disputed some of the findings in his PhD:
see here:
American Press Association - Cosmologist Solves NASA Mystery
Stephen personally acknowledged to some discrepancies and has published several works that has taken the light of these new revelations.
Even people with extraordinary brains such as Nash,or Von Neumann were wrong from time to time, and these were the kinds of brain who could solve Riemannian manifolds, Euclidean computations in their head half asleep were still wrong in their early assertions.
If these geniuses by earthly standard made retractions on their previous work,why should Mwakyembe remain static?Not that he cares as i believe he is no longer doing active research.
I can not imagine any academic settings where people will be afraid to pen down what they believe to be right for the mere worry of having to be wrong. Do you understand the courage it takes to work on research,performing the same damn experiment for 3-4 years?and almost exactly be wrong 99% of the time until that Eureka moment comes through? Research is not based on being right, rather on original thinking and formulating of clear hypothesis.
Infact you would be shocked to know how many PhD dissertations are wrong year in year out. a 300 page thesis does not need to be 100% accurate to contribute to knowledge, sometimes being wrong is crucial for the next researcher who is going to write a literature review of your work(what Lisu is doing) for seeing past mistakes is seen in research as the first step towards solving any problem.
