The article stresses some notions related to ontological and epistemological issues, the source of which are questions about the possibilities and manner of exploring mental handicap.

The article raises the notions related to a field researcher’s workshop, difficulties in data acquisition, the emotional context of exploring the environment of persons with disabilities, as well as the ethical and moral dilemmas that provide an indispensable element of such a research undertaking.
