Doctor of Philosophy


Doctor of Philosophy, abbreviated Ph.D. or PhD for the Latin philosophiƦ doctor, meaning "teacher of philosophy", or, more rarely, D.Phil., for the equivalent doctor philosophiƦ, is an advanced academic degree awarded by universities. In many, but not all countries in the English-speaking world, it has become the highest degree one can earn (but see also the higher doctorates awarded by universities in the UK, Ireland and some Commonwealth countries) and applies to graduates in a wide array of disciplines in the sciences and humanities. The Ph.D. has become a requirement for a career as a university professor or researcher in most fields.
The detailed requirements for award of a Ph.D. degree vary throughout the world; however, there are a number of common factors. In some countries (the US, Canada, Denmark, for example), most universities require coursework for Ph.D. degrees. In many other countries (especially those with a greater degree of specialization at the undergraduate level, such as the UK) there is no such condition in general. It is not uncommon, however, for individual universities or departments to specify analogous requirements for students not already in possession of a master's degree.
In countries requiring coursework, there is usually a prescribed minimum amount of study — typically two to three years full time, or a set number of credit hours — which must take place before submission of a thesis. This requirement is usually waived for academic staff submitting a portfolio of peer-reviewed published work. The candidate may also be required to successfully complete a certain number of additional, advanced courses relevant to his or her area of specialization.
A candidate must submit a thesis or dissertation consisting of a suitable body of original academic research, which is in principle worthy of publication in a peer-refereed context.[1] In many countries a candidate must defend this work before a panel of expert examiners appointed by the university; in other countries, the dissertation is examined by a panel of expert examiners who stipulate whether the dissertation is in principle passable and the issues that need to be addressed before the dissertation can be passed.
Universities in the non-English-speaking world have begun adopting similar standards to those of the Anglophone Ph.D. degree for their research doctorates (see, for example, Bologna Process).[2]


History of the Ph.D. degree


The origins of the doctorate dates back to the ijazat attadris wa 'l-iftta ("license to teach and issue legal opinions") in the medieval Madrasahs from the 9th century, though it was limited to Islamic law at the time, as in a Doctor of Laws degree.[3] The doctorate was later extended to philosophy in the European universities in the Middle Ages which generally placed all academic disciplines outside the professional fields of theology, medicine and law under the broad heading of "philosophy" (or "natural philosophy" when referring to science). The degree of Doctor of Philosophy was a doctorate, generally granted as honorary degrees to select and well-established scholars.[citation needed]
According to Wellington, Bathmaker, Hung, MucCullough and Sikes (2005), the first Ph.D. degree was awarded in Paris in 1150, but not until the early nineteenth century did the term "Ph.D. degree" acquire its modern meaning as the highest academic doctoral degree, thanks to university practice in Germany. As Wellington et al. explain, prior to the nineteenth century professional doctoral degrees could only be awarded in theology (Th.D.), law (J.D.), or medicine (M.D.). In 1861, Yale University adopted the German practice (first introduced in the 19th century at the Friedrich Wilhelm University in Berlin) of granting the degree to younger students who had completed a prescribed course of graduate study and successfully defended a thesis/dissertation containing original research in science or in the humanities.[4]
From the United States the degree spread to Canada in 1900, and then to the United Kingdom in 1917.[5] This displaced the existing Doctor of Philosophy degree in some universities; for instance, the D.Phil. (higher doctorate in the faculty of philosophy) at the University of St Andrews was discontinued and replaced with the Ph.D. (research doctorate). Oxford retained the D.Phil. abbreviation for their research degrees. Some newer UK universities, for example Buckingham (est. 1976), Sussex (est. 1961), and, until a few years ago, York (est. 1963), chose to adopt the D.Phil., as did some universities in New Zealand.
