The Structure of Scientific Revolutions by Thomas Kuhn

The Structure of Scientific Revolutions by Thomas Kuhn is considered one of the most influential books of the twentieth century, in scientific and philosophical circles. This book is a fundamental part of the historical and sociological account of the philosophy of science. It is also an important piece in the theory of scientific knowledge and its development throughout history.

In The Structure of Scientific Revolutions, Kuhn outlines the concept of ‘paradigm shift’ - a notion of how science progresses. He proposes that, over time, a certain set of ideas and belief systems become entrenched in the scientific community and subsequent work is done within the ‘paradigm’ of these ideas and beliefs. As these beliefs hold sway over the scientific community, ‘normal science’ is performed and the ‘paradigm’ is extended to new areas of inquiry. This ‘normal science’ is open to modifications and interpretations but, until anomalies and incongruities appear, it remains relatively unchanged as it works within the framework of the existing paradigm.

When two paradigms become contrasted and incongruities in the theories of the two paradigms surface, then a ‘crisis’ is born and a ‘scientific revolution’ takes place as the scientific community works to reconcile the rival paradigms. Whenever a new paradigm is introduced, or old one is abandoned, it has been claimed - by some - that this is an accusation of ‘philosophical relativism’. A key contribution of Kuhn’s is to argue that there are ‘incommensurability of paradigms’ meaning there is no concrete and correct way to determine which paradigm is correct. This notion divides opinion sharply, particularly among those in the scientific community who would prefer to believe that scientific theory and methods are correct, as opposed to being relative to the particular paradigm in use.

In his famous work, Kuhn argued that scientific progress is only made through successive breakthroughs, rather than gradual progressions. He argued that this approach to science is more effective than attempting to advance through ‘gradual refinement’. This notion of paradigm shifts has been both contested and embraced. Supporters of Kuhn argue that accruing knowledge in the sciences often involves periods of ‘normal science’ and long periods of stability before the advent of revolutionary breakthroughs and new paradigms.

Kuhn’s insights into the structure of scientific revolutions have become embedded in the study of the history of science, helping to explain why certain ideas became popular at certain times and why certain problems remained intractable. Through his work, Kuhn has altered the course of twentieth century historiography and philosophies of science, and his writing continues to provide a valuable - and even crucial - resource for understanding how scientific ideas arise and evolve.

In conclusion, The Structure of Scientific Revolutions by Thomas Kuhn is one of the most influential books of the past century, particularly in the realm of the philosophy of science. It outlined the concept of the ‘paradigm shift’: the notion that one paradigm of understanding holds sway over the scientific community until anomalies in the theory surface, leading to a revolution in understanding as two paradigms battle for ascendancy. The notion of Kuhn’s ‘incommensurability of paradigms’ continues to divide opinion, but his work has been a fundamental contribution to the understanding of the structure of scientific revolutions and has changed the face of twentieth century historiography and the philosophy of science.
