What is the Full Form of PhD?
The full form of PhD is “Doctor of Philosophy.”
Despite having “Philosophy” in its name, a PhD is not restricted to the study of philosophy alone. The term Philosophy in this context originates from the Greek word philosophia, which means ‘love of wisdom.’ Thus, a PhD represents the pursuit of knowledge in a particular field, whether it’s engineering, social sciences, literature, biology, physics, business, or any other discipline.
What is a PhD?
A PhD is a doctoral-level academic degree awarded by universities and higher education institutions to students who have completed advanced study and original research in a specific area of study.
It is the highest academic qualification in most educational systems globally. A PhD program typically involves:
- Extensive academic coursework
- In-depth original research
- Publication of findings in academic journals
- Writing a dissertation or thesis
- Defending the dissertation before an expert panel
The primary purpose of a PhD is to contribute new, original knowledge to your field of study.
History of the PhD
The concept of a PhD originated in medieval European universities where ‘Philosophy’ denoted a universal love for knowledge encompassing all academic disciplines. In those times, any doctor-level degree was termed a Doctor of Philosophy.
Over time, the PhD degree expanded beyond philosophy to other subjects and fields, but the traditional title remained intact, symbolizing the highest pursuit of wisdom and knowledge.
