Political science has come so far as a discipline that different schools and scholars have different interpretations of science in the study of politics, and that diversity is important to maintain. The past two decades have seen an explosion of political voice across the developing world. From the shift towards democracy in Africa, Asia, and Latin America and the mushrooming of citizen-led initiatives to hold those in power to account, to the uprisings in the Middle East and North Africa and the eruption of protest movements in countries as diverse as Brazil, Egypt, India, and Turkey, we now have a wealth of experience we can use to reimagine the role of engaged populations in political processes and to redefine the very substance of democracy. The concept of Political Science as a study of State, Government and national Institution is not considered adequate today. The scope of political science is vast and experts have divided the field of political science into five sub-disciplines that are political theory, public administration, comparative politics, international relations, and public law. It needs to be noted that these sub-disciplines cover the entire gamut of the modern political economy and provide the basis for the study and understanding of how the global political economy works. The study of the matters concerning the allocation and distribution as well as the transfer of power is one of the main preoccupations of political scientists. The success or otherwise of the governance structures is gauged by political scientists who examine the multifaceted and multilayered factors at work that contribute to good or bad governance.
This book entitled “Introduction to Political Science” lays emphasis on its being the study of power and authority. It also explains its ever-widening scope. Its scope includes study of the state and the study of political system; covering the study of government, study of power; study of man and his political behaviour and study of political issues which influence politics directly or indirectly. Economic growth is probably the most powerful causal factor accounting for variation in human development across space and through time and has been explored in several recent studies. Yet, it is clearly not the only factor. Indeed, countries with similar levels of economic development sometimes experience radically different levels of human development. Thus, it is vital that we extend the purview of work on this subject to include other structural-level factors that might impact the life-conditions of the world’s poor. The focus in this book is on the role of political institutions, whether democracy, constitutional structures, or state capacity have consistent, independent effects on human development. This edition will be of valued to anyone studying institutionalism, as well as political institutions, and public administration.
