The question of whether to refer to someone with a Doctor of Philosophy (Ph.D.) degree as “Doctor” is a common point of confusion. The title is entirely appropriate for a Ph.D. holder, as the degree represents the highest academic achievement awarded by a university. Uncertainty stems from the widespread association of the title “Doctor” with medical practitioners. Understanding the historical context and modern distinctions provides a clear guide for correct usage.
The Academic Origin of the Title “Doctor”
The title “Doctor” is fundamentally an academic designation tracing back to medieval European universities. The term originates from the Latin verb docere, which translates directly to “to teach,” signifying a “Master Teacher.”
The first doctorates were awarded in the 12th and 13th centuries at institutions like the University of Bologna and the University of Paris. This degree, known as the licentia docendi, granted the recipient the formal license to teach at a university level. It was the highest degree conferred and was initially reserved for theology, law, and medicine.
The Doctor of Philosophy (Ph.D.) degree continues this ancient academic tradition. The term “philosophy” is used in its broader Greek sense, meaning “love of wisdom.” The Ph.D. became the standard research degree across all academic disciplines, from the humanities to the natural sciences.
A Ph.D. holder is recognized as having contributed original research that expands human knowledge. The title “Doctor” acknowledges this scholarly accomplishment and the qualification to instruct others in their specialized field.
Distinguishing Academic and Professional Doctorates
Confusion arises because the public primarily encounters individuals with professional doctorates, particularly in medicine. A clear distinction exists between the academic research doctorate (Ph.D.) and professional practice doctorates (M.D.). Both types correctly confer the title “Doctor,” but they represent different educational pathways and professional goals.
The Ph.D. is a research-focused degree requiring the completion and defense of a dissertation presenting new, original knowledge. This degree trains scholars and researchers for careers in academia or scientific investigation. The training emphasizes theoretical understanding and the discovery of new principles.
In contrast, professional doctorates are practice-oriented, focusing on applying existing knowledge to a specific profession. The M.D. degree involves intensive clinical training designed to prepare practitioners for direct patient care. Other professional degrees, like the Doctor of Education (Ed.D.) or Doctor of Psychology (Psy.D.), focus on advanced application within their respective fields.
Medical doctors adopted the title “Doctor” for professional recognition, becoming commonplace in the 18th and 19th centuries. This widespread usage in a highly visible profession led to the assumption that the title is exclusively medical. Both the research-focused Ph.D. and the practice-focused M.D. are legitimate doctoral degrees, and their holders are entitled to the designation.
Etiquette for Using the Title in Different Settings
The decision to use the title “Dr.” for a Ph.D. holder depends heavily on the specific social or professional environment. In academic and formal settings, the use of the title is standard and expected. Official correspondence, academic introductions, and university environments require using “Dr.” as a sign of respect for scholarly achievement.
In social or informal contexts, the etiquette is more flexible and guided by personal preference. While it is never incorrect to address a Ph.D. holder as “Doctor,” many prefer to be called by their first name outside of their professional sphere. The appropriate approach is to use the title upon first meeting and then follow the individual’s lead if they suggest a less formal address.
For professional environments outside of academia, such as corporate or government workplaces, usage is determined by company culture and the degree’s relevance to the job. If the Ph.D. relates directly to the person’s expertise, the title is often used in formal communications. If the degree is not pertinent to the daily work, the title may be dropped in favor of a first name.
Ph.D. holders generally reserve the title for professional and academic contexts. The title serves to establish credibility and authority within a field of expertise. If there is any doubt about how to address a person with a doctorate, using “Dr.” is the most respectful and correct choice.
