 The evaluative meaning of “terrorism” has shifted considerably more than once. So has its descriptive meaning, but to a lesser degree. Whatever else the word may have meant, its ordinary use over more than two centuries has typically indicated two things: violence and intimidation (the causing of great fear or terror, terrorizing). The dominant approach to the conceptual question in philosophical literature reflects this. Terrorism is usually understood as a type of violence. This violence is not blind or sadistic, but rather aims at intimidation and at some further political, social, or religious goal or, more broadly, at coercion.
