When embarking on dissertation research, it is essential to understand the philosophical foundations that shape your study. Three key philosophical concepts—epistemology, ontology, and axiology—play a critical role in determining how research is approached, conducted, and interpreted. Understanding these concepts will not only strengthen the theoretical foundation of your dissertation but also ensure coherence in your research design and methodology.
Epistemology: the nature of knowledge
Epistemology is concerned with the nature, scope, and justification of knowledge. It explores how we come to know things, what counts as knowledge, and how knowledge can be validated. In dissertation research, epistemology influences the choice of research methods and the interpretation of findings. There are two main epistemological positions:
Positivism – Assumes that knowledge is objective, measurable, and derived from observable phenomena. Positivist research often uses quantitative methods, such as experiments or surveys, to test hypotheses and establish generalizable facts.
Interpretivism (or Constructivism) – Argues that knowledge is subjective and socially constructed. Interpretivist research typically employs qualitative methods, such as interviews or case studies, to understand human experiences and meanings.
Your epistemological stance shapes how you collect and analyze data, determining whether you focus on objective facts or subjective interpretations.
Ontology: The nature of reality
Ontology deals with the nature of reality and what exists. It addresses fundamental questions about whether reality is independent of our perceptions or socially constructed by individuals and groups. There are two primary ontological perspectives:
Realism – Suggests that reality exists independently of human perception. Realists believe that there are objective truths that can be discovered through empirical research.
Relativism – Proposes that reality is subjective and differs based on individuals’ or cultures’ perspectives. This view aligns with qualitative research, where multiple realities are explored.
Understanding your ontological stance helps define your research approach—whether you aim to discover an objective reality or explore diverse perspectives and experiences.

Axiology: The role of values in research
Axiology concerns the role of values and ethics in research. It examines how researchers’ beliefs, biases, and ethical considerations influence the research process. Axiology is especially relevant when selecting research topics, determining methodologies, and interpreting findings.
Objective axiology – Suggests that research should be value-free, emphasizing neutrality and detachment.
Subjective axiology – Recognizes that research is influenced by the researcher’s values, experiences, and ethical considerations.
Axiology is crucial in dissertation research, as it guides ethical decision-making, the selection of research questions, and the interpretation of data. Researchers must be transparent about their biases and ethical responsibilities to ensure credibility and integrity.
Applying these concepts to dissertation research
When designing your dissertation, it is vital to clearly define your epistemological, ontological, and axiological positions. These concepts influence:
- Research questions – A positivist, realist stance may lead to hypothesis-driven questions, while an interpretivist, relativist stance may focus on open-ended inquiries.
- Methodology – Your epistemology and ontology guide whether you use quantitative, qualitative, or mixed methods.
- Ethical considerations – Axiology ensures that your research is conducted ethically and reflects awareness of potential biases.
By thoughtfully considering these philosophical foundations, you can create a well-structured, coherent, and academically rigorous dissertation that aligns with your research objectives.
