TH&E studies as separate academic subjects, or combined as an academic branch, can act as a field that is taught to students, an academic genre to study, and more importantly as a practice aimed at enhancing and enriching the society within which TH&E takes place. I will in this chapter refer to TH&E studies, fully conscious of the fact that studies in these sub-fields take different shapes, and are taught separately from one another at some institutions. My aim in this chapter is, however, to investigate the philosophical foundations and issues of these studies, and as they have fairly similar antecedents I will disregard the diversity they take in practice. They are dealt with here together as TH&E studies.
