THEORY AS THE ENGINE OF RESEARCH: A CRITICAL EVALUATION OF THE
ROLE AND SIGNIFICANCE OF THEORISATION IN THE RESEARCH PROCESS
1. INTRODUCTION
In every field of academic inquiry, researchers attempt to understand, explain, and
interpret phenomena that matter to people and the world they live in. Research is not
merely about gathering facts or applying methods; it is a thoughtful process shaped
by the beliefs, values, and frameworks researchers bring to their work. The
statement "Theory is the engine of research" captures this reality. Theory drives
research by giving it purpose, direction, and meaning. It shapes the questions we
ask, how we go about answering them, and how we interpret the findings. Without
theory, research risks becoming an empty technical process, devoid of depth and
purpose. It becomes, as Jackson and Mazzei argue, little more than a repetition of
methods, ignoring the deeper ontological and epistemological foundations of inquiry
(Jackson & Mazzei, 2018).
This essay critically evaluates the importance of theorisation in research. It explains
why theory should be understood as the foundation of all scholarly work, explores
various paradigms and theoretical approaches, and shows how theory provides the
intellectual framework needed for inquiry. It draws on a wide range of academic
sources, from Thomas Kuhn to Patti Lather and Karen Barad, to show how theory
helps researchers move beyond surface-level observation into deeper levels of
analysis, questioning, and engagement. The essay also addresses critiques of
theorisation and reflects on the challenges of applying theory responsibly in an ever-
changing world.
In a world filled with complex problems, researchers cannot afford to work without
theory. Theory not only helps us understand what is, but also opens up the
possibility of imagining what could be. For this reason, theory is not simply an
optional add-on to research. It is, indeed, its driving force.
2. UNDERSTANDING THEORY IN RESEARCH
Theory in research refers to a system of ideas that helps us to explain, understand,
and interpret phenomena. It is not simply an abstract concept detached from practice
