The double life of ideology: from revolutionary science to radical creed

In short: Is ideology a tool for liberation or a weapon of manipulation? From its 18th-century origins as a 'science of ideas' intended to free the human mind, the concept has evolved into a complex mechanism for social engineering, political struggle, and the mobilization of total commitment.

The term 'idéologie' was coined in the late 18th century by French philosopher A.-L.-C. Destutt de Tracy during the French Revolution. He proposed a 'science of ideas' intended to rid the human mind of prejudice and prepare citizens for the 'sovereignty of reason.' Unlike purely explanatory philosophies, Tracy’s vision was programmatic; it aimed to actively improve human life and transform France into a rational society. However, this dual nature—being both an intellectual theory and a practical plan for change—meant the word quickly became polarizing. While Tracy saw it as a laudatory science, Napoleon Bonaparte later used the term with scorn, blaming 'idéologues' for France's military failures.

In a strict sense, an ideology is defined by five core characteristics: it provides a comprehensive theory of the world, sets out a program for social organization, assumes that achieving this program requires a struggle, seeks to recruit committed adherents rather than just persuade them, and addresses a wide public while often granting leadership to intellectuals. These features distinguish true ideologies from mere opinions. They are often associated with the rise of secular beliefs in the 19th and 20th centuries, replacing traditional religious faith with systems like communism, fascism, and various forms of nationalism.

The Islamic State (IS) exemplifies the high-commitment, struggle-oriented nature of ideology. Its creed, defined as a 'middle way' between extremist and lax interpretations, blends Salafi jihadism, Wahhabism, and Qutbism. While some scholars, like Cole Bunzel, suggest not all members fully grasp the group's specific ideology, others like Bernard Haykel argue that Western observers often underestimate the passionate attachment of even the rank-and-file to religious doctrine. For IS, ideology is not just a theory; it is a call to restore a caliphate, purge 'apostasy,' and prepare for a final Day of Judgment through active, violent struggle.
