This dissertation comprises an introduction, seven previously published papers dealing with aspects of psychodrama and the person-centred approach, criticisms of the person-centred approach, an assessment of my contribution to person-centred theory and practice and an 'afterword' which brings my exploration up to date. Although each of the papers draws on my practical experience as a therapist, researcher and educator, two of them are accounts of research, the others are broadly 'conceptual'. They are presented in the context of an heuristic journey which demonstrates my development as a person-centred thinker and practitioner. The introduction establishes this over-arching heuristic framework and gives my rationale for including these papers. The papers are followed by a consideration of the criticisms of the person-centred approach in which I show (with reference to the literature) how, if I can, I answer these criticisms. In the penultimate chapter I examine my papers in the light of some of the 'critical issues' with respect to the person-centred approach.
