A PhD level dissertation is something you can easily call a lengthy and formal writing a dissertaiton. Among the requirements that are usually applied to PhD dissertations there is one that calls for originality. This is the very essence of your PhD dissertation. It has to be absolutely unique and talk about the earlier uninvestigated problem. PhD level dissertations, certainly, refer to previously written theories and popular researchers, but it is only 20% of the overall work. A PhD level dissertation that is made of other scholars’ theories and half plagiarized can not be called an authentic writing. They can certainly not be called PhD level dissertations.

      PhD level dissertation is a piece of substantial writing. PhD level dissertations usually argue in defense of a particular thesis that has to be new and non-researched, as well. As for the scholarly methodology of the PhD dissertation, it has to boil down to the stated hypothesis and pay attention to the evidence.

      Collecting evidence for the PhD level dissertation takes as much time as actually writing a PhD dissertation. Not only you will have to analyze, evaluate and systematize the sources and data, but you will also have to organize all the gathered evidences in a form of a discussion, where your theory has to come forward.

      PhD dissertations call for critical thinking: lessons learned, results obtained while researching etc. As for the statements, there is a strict rule in PhD dissertations: all statements have to be supported in a certain way. You can do it either by backing them up with references to already published materials or by original works.

      A mistake that has to be avoided in PhD level dissertations is the repetition of summaries and copy-pasting of already published works.
