| Added in edit: Assuming it's not possible to change advisor ... You have to make a decision: Quit, or take control of your own education and finish. You will need your supervisor to deal with the administrative aspects of your degree, so you can't avoid him entirely. However, you can limit your contact with him to that role alone. However, you will need someone to supervise your academic requirements. So you need to find someone with whom you can talk about your work, and possibly with whom you can collaborate. A supervisor suggests problems to work on, suggests material to read and understand, monitors that you're working hard enough, checks on your progress, and if your progress isn't adequate, suggests modifications to the current schedule/scheme of work. You will need to do almost all of that yourself, or find someone else to collaborate with to accomplish those academic aspects. But it can be done, and if you succeed it becomes a major, major accomplishment on your CV. But you really need to take control. Or quit. |
I agree with your advice except for this line. To be clear, a Ph.D does count as a "major, major accomplishment on your CV" (at least to the right audience). But you won't get any extra credit for putting up with a bad adviser.
I am tempted to simply advise quitting, but switching to another adviser (or even sticking it out) could also make sense. It depends on how exactly your adviser is bad, and whether you could honestly expect another Ph.D. adviser to be significantly better. Actual abuse is one thing, but benign neglect and a "sink or swim" attitude are pretty typical attitudes. If the problem is that your adviser is just focused on raising funds and doesn't have much time or inclination to help you on your research, then you can't expect any better if you roll the dice another time.
Also - what field are you in? What are your career goals? Most people with Ph.Ds don't end up in jobs that require them. If you think you'll be dropping out of academia in three years anyways (and there's no shame in that), then there really is little reason to stick it out for three more years of suffering, regardless of the whys.
