A consultant is a professional engaged to offer specialized expertise or guidance, often in complex or niche fields. This theme is examined through various perspectives: Arthur Conan Doyle depicts consultants as motivated by practical, familial duties, while George Bernard Shaw emphasizes their role as expensive, last-resort options in medicine.
Edward L. Bernays portrays consultants as strategic advisors in public relations, and David H. Rothman warns of their potential to exaggerate issues. Across literature and practice, the consultant appears both as a reliable expert and a figure of calculated usefulness, bridging the gap between knowledge and its application.
