I chose to do an MPhil for two reasons. Firstly, because it gave me great flexibility to work on the topics that interested me the most. In standard taught masters programmes, your studies are restricted to those courses that are made available by the department that year. But the MPhil allows you to work on more or less whatever you want, provided you can find a member of the department willing to supervise them. Warwick has a large and diverse philosophy department so it should be easy to find specialists to supervise you on your areas of interest. Secondly, I chose to do an MPhil because I knew I wanted to continue with philosophy at a PhD level and beyond.
In this regard, the MPhil programme is the obvious choice after an undergraduate degree. It is not that taught masters programmes shut any doors - and many students continue on to complete PhDs and have careers in academia. However, it would be fair to say that the MPhil specifically targets the independent research skills needed to succeed in academia, through one-on-one supervisions and completion of an extended 30,000 word thesis. The MPhil is structured so that you have regular meetings with supervisors to discuss papers you have written. The supervisions are tough - you can expect to have your papers pulled apart at first. However, this just means that when you come to redraft them for assessment they will be that much stronger. All my supervisors have been great and have certainly helped to make my papers significantly better than they would otherwise have been.
