One obvious career choice is academic. This will involve guiding, teaching and counseling students. You will conduct research and publish your findings. These will normally be in the form of academic papers submitted to journals, as well as books. A successful academic career could lead to chairmanship of a department.
Consider becoming a writer and/or consultant after you have developed a strong reputation in your field. The work can include media interviews and advising government and private business in areas such as ethics and the wider implications of economic and political decisions and policies.
As an expert in the liberal arts, you may find employment in non-profit organizations. These organizations often consider more than just economic values, such as ethics, holistic and creative thinking and pragmatism.
In a modern, flexible job market, you may have to consider areas outside your specific area of expertise. These include working in the public sector, in management and as a journalist, as well as overseas posts with non-government and government organizations. Working for a multinational company may also be an option.
