What are some good solid reasons to study Philosophy in the Twenty-First Century? I'n not talking about ethics or logic, primarily epistomology, the history of philosophical thought, and so on.

Thanks.

Because you find it interesting

Why Study Philosophy? (http://www.philosophy.ubc.ca/undergrad/why-philosophy.html)
" This is partly because philosophy touches on so many other subjects, and partly because its methods are widely applicable to other areas of intellectual accomplishment. Communication skills, critical reasoning skills, and general problem-solving skills are all enhanced by work in philosophy. They are also essential to many other disciplines and projects. In addition, philosophy helps students develop sound methods of research and analysis. By its nature, Philosophy also helps students to organize and unify information that they may have learned only in a piecemeal way in other courses."
